When do I need a mouthguard for teeth grinding?

You may need a mouthguard, known as a nightguard, if you have a chronic teeth grinding habit. If you don’t address the physical/psychological reasons for your teeth grinding habit (i.e. stress), nor use a night guard, you may experience further complications that may put your teeth at risk of permanent damage.

That said, everyone grinds, clenches or gnashes their teeth at one time or another. Most times we don’t even know we do it because teeth grinding, or bruxism, is usually subconscious behaviour, and symptoms aren’t always noticeable at first. It’s not until a partner or carer notices, or one experiences advanced symptoms that you may start to figure out what you’ve been doing with your teeth at night. But when does grinding become a problem that puts your oral health at risk?

The common symptoms of bruxism that indicate you may need to wear a “night guard” mouthguard from your dentist, include:

  • Dull headaches or ear pain – if you wake up with either of these symptoms, the reason could be teeth grinding at night.
  • Sore toothaches – a dull toothache may indicate excess pressure on your teeth from grinding.   
  • Facial stiffness – this symptom may indicate that your facial muscles have tensed for a long period indicating extended teeth grinding.
  • Medication – some medications, such as anti-depressants, cause teeth grinding while you sleep.
  • Non-stop grinding – if you have temporary or chronic stress issues, your teeth may be grinding on them at night.
  • Intense jaw clenching – this may cause your teeth to clench also.
  • Chipped tooth – if you notice a chip on a tooth or wear on the cusps/edges of your teeth – that is not the result of “poor” food choices (e.g. ice cubes) – you may be grinding your teeth excessively.
  • Sore, inflamed jaw joints in the morning – this may be a sign of temporomandibular joint disorder (TMJD) which can occur from teeth grinding.

If you suspect that you have any of the signs and symptoms listed above and may be grinding your teeth, the next step is to see your dentist for a proper diagnosis and potential treatment options.

Teeth grinding may arise from a range of physical and/or psychological issues that will need to be dealt with – especially for children who are experiencing stress, anger and/or anxiety issues.  In the meantime, if you (or a family member) are experiencing bruxism, your dentist can help prevent any further oral health complications – such as attrition – by fitting you with a custom “nightguard” mouthguard that you can wear comfortably at night.

Magnetic microbots to become dental assistants

Magnetic microbots to become dental assistants

An American research and development team made up of engineers, biologists and dentists at the University of Pennsylvania have created the next generation of dental assistants – teeny-tiny micro-robots.

These micro-robots are capable of cleaning biofilms, such as oral plaque, with great control and precision via an external magnetic field.

What are bio-films?

Bio-films are thin, slimy, highly-resilient films containing bacterial colonies that can be home to several hundred bacterial species. Bio-films secret a glue-like substance and can stick extremely well to any non-shedding surface.

Examples of biofilms include oral, arterial and brain plaques, as well as biofilms in catheters or water lines.

How do dental micro-robots work?

Dental micro-robots are a type of CAR device which stands for Catalytic Antimicrobial Robots. They are able to completely and systematically breakdown and remove biofilms from a range of surfaces, including the curved surfaces of a tooth. At the same time, CARs kill embedded bacteria and all other residual material until there is nothing left of the biofilm but a completely clean surface.
How are dental micro-robots controlled?

Dental micro-robots, or CARs, are controlled and driven by external magnetic fields, in a similar way to how an aquarium magnet cleaner uses a magnetic handle to control a magnetic scrubber on the inside of aquarium glass. CARs, like aquarium scrubbers, are magnetic also, and follow the direction of an external magnetic field.

Pending further technological development, the motion and direction of the CARs will be actively informed by 3D image scans of the dental plaque sooner or later, which will make them more intelligent and effective at targeting dental plaque on a range of tooth surfaces.

Dental Health Week 2019 – Are you tracking your oral health?

Dental Health Week 2019 starts today and will continue for the next week! So what is Dental Health Week?  It’s Australia’s own annual oral health promotion week which aims to remind Australians adults and kids about the importance of keeping good oral health.

This year event is all about keeping track of the oral health of you and your family. Unfortunately, this is a responsibility that not all Aussies are taking seriously enough.

According the Australian Dental Association’s Oral Health Tracker report card on the oral health habits of child, teen and adult Australians:

  • 65% of Australians haven’t visited their dentist for a check up for two years,
  • Half of Australians only brush their teeth once daily,
  • Approximately 40% of Australians don’t floss or use interdental brushes for the spaces in between their teeth and around their gums, and
  • 73% of teens aged 14 to 18 years are eating too much added sugar.

So, what’s the message to all Australians from the ADA regarding these serious community oral health issues?

  1. Visit your dentist for regular checkups and preventative dental treatment, once or twice a year.
  2. Brush your teeth TWICE a day with fluoride toothpaste – once when you wake up and again before you go to bed.
  3. Make sure you clean the interdental spaces between your teeth at least once a day, using floss, piksters or interdental brushes.
  4. Ensure your child eats a balanced, healthy diet, and limit their intake of added sugars.

Keeping track of your oral health is so important to avoid serious complications to your oral and general health – now and later in life. Happy Dental Health Week from the TC Dental team!

How much fluoride is just right for good oral health?

How much fluoride is just right for good oral health?

Fluoride is a natural occurring mineral that is found in the environment in water sources that have filtered through volcanic rocks and soil. There is no question that fluoride is an essential factor to develop and maintain strong healthy teeth. This reduces the risk of tooth decay and other oral health complications.

How is fluoride delivered?

Fluoride can be delivered to the body systemically or topically.

Topical fluorides include fluoride toothpastes, mouth rinses, gels and varnishes. These act by strengthening the teeth directly, and making them more resistant to tooth decay. However, the beneficial effects of topical fluorides, apart from varnishes, wear off easily. This is why you should wait at least 30 min after applying topical fluorides before eating or drinking again.

Systemic fluorides are ingested and integrated into developing tooth structures. Systemic fluoride can be found in tap water, fluoride supplements, and food and drinks such as shellfish, chicken, potatoes, grapes and rice. If these foods have been prepared with tap water, the concentration of fluoride is further increased. Once systemic fluoride enters the body, it can also make its way into your saliva, which provides a continual fluoride wash over your teeth.

How much fluoride is required by the body?

The amount of fluoride your body needs depends on your body weight. As a general rule, children need 0.5mg (500?g) of fluoride daily. This why kids should only use a small pea-sized amount of toothpaste on their toothbrushes, and be taught to spit not swallow. Adults need between 3 to 4mg (3000-4000?g) daily.

The upper limit of fluoride intake is 2.5 times the recommended intake. Beyond this level, fluoride may have negative health effects.

Too much fluoride can lead to fluorosis

While the right amount of fluoride intake is essential to strengthen tooth enamel and prevent oral health issues, too much can have adverse effects. If a child consumes too much fluoride as their teeth are developing, they can experience an oral condition called fluorosis.
Fluorosis leads to white or brown discolouration or spots on tooth enamel. However, it is only a cosmetic effect and affects the appearance of teeth, not their health or strength. If you are a parent and notice any of these signs, consult with your family dentist. They can determine if any discolouration is the result of fluorosis, and recommend ways to limit your child’s fluoride intake.

On the other hand, your dentist may identify signs of a fluoride deficiency, which should also be avoided as this leads to softer enamel and weaker teeth.

Teens risk tooth damage by using DIY teeth whitening products

Teens risk tooth damage by using DIY teeth whitening products

In a recent joint statement, the Australian Dental Association (ADA) Deputy CEO, Eithne Irving and Melbourne-based dental practitioner, Dr Toni Surace have advised parents and teens that DIY teeth whitening kits and products are unsuitable for children and teens under the age of 18.

Teens under pressure to look “perfect”

In this day and age of social media, too many teens feel pressured to live up to unrealistic standards of perfection, in order avoid negative comparison, criticism and bullying from their peers. As a result, they are experiencing problems with their health and wellbeing.

Along with anxiety, loss of self confidence and eating disorders, teens are now risking their oral health in an effort to look “perfect”. Unfortunately a lot of teens are attempting to achieve a dazzling, bright smile with DIY teeth whitening products that are primarily aimed at the adult market.

DIY teeth whitening products are unsuitable for developing teeth

According to Ms Irving, off-the-shelf DIY whitening kits and products were not only ineffective for maturing teeth, but had the potential to seriously damage a child’s teeth and gums.

Most teens don’t realise that their adult or permanent teeth don’t reach their maximum “whiteness” until lighter coloured enamel develops after several years. But in order to achieve their best smile and gain more “likes”, teens are resorting to “quick fix” DIY whitening products that pose a number of risks to their oral health.

Furthermore, if teens use high concentrations of bleach – that aggressively remove their tooth enamel – they may end up spitting out their “liquefied” teeth down the sink.

Dental problems that teens may experience through using whitening products include:

  • irreversible erosion & thinning of developing tooth enamel
  • ulcerations
  • chemical burns to gums
  • gum shrinkage
  • patchy teeth
  • tooth sensitivity & toothaches
  • oral infection
  • stomach problems from swallowing bleaching products

Teeth whitening products & remedies that teens (under 18) should avoid include:

  • over-the-counter teeth whitening kits
  • LED light treatment
  • whitening strips
  • whitening toothpaste
  • lemon juice
  • charcoal

Cranberries to help in the fight against tooth decay

Cranberries to help in the fight against tooth decay

In March 2019, oral health researchers at the University of Queensland published the results of a study on the oral bacterial fighting properties of cranberries and other dark-coloured fruit berries.
Previous clinical research has shown cranberry polyphenols to have antimicrobial qualities. But the UQ team took another step, and further investigated the effects of cranberry extracts on oral bacteria samples derived from saliva.

What they found was that cranberries are excellent for your oral health!

Traditional benefits of cranberry

There has always been an awareness of the health benefits of cranberries in recorded human history. The American cranberry had been used by Native American Indians for centuries to treat scurvy, and to help heal stomach and liver problems.

Earlier still, the Ancient Romans were well aware of its medicinal value. And in England, cranberries were a go-to remedy for diarrhoea, scurvy, fevers, and skin, urinary and genital infections.

Nowadays, clinical studies have proven that cranberries are indeed medicinally beneficial for many of the same ailments that ancient people experienced. However, science has gone on to discover other health benefits including lowering the risk of heart and neurological disease, regulating inflammation and inhibiting cancer cell proliferation.

The UQ Cranberry test results.

The UQ researchers’ test results show that the polyphenols, or phytochemicals, abundantly present in cranberries had a significant inhibiting effect on the types of oral bacteria that cause tooth decay and cavities.

After a 12 hour period, oral bacterial bio-film samples treated with cranberry extracts showed a 38% drop in bio-mass, a 44% reduction in acid formation and a 51% reduction of bacterial colony forming units (CFUs).

The UQ researchers now plan to develop an oral care and hygiene product for daily use containing the medicinally beneficial Cranberry extract used in their study.

Common cosmetic dental problems

Common cosmetic dental problems

Having healthy teeth and gums is important for chewing and breaking down food for better digestion, as well as optimal nutritional intake. If your teeth and gums aren’t healthy, you may experience oral and general health complications as a result. That’s where your dentist steps in, for they can help treat oral conditions and disease so that your oral health stays on track.

However, there is another important job that dentists do – cosmetic dentistry. Cosmetic dentistry refers to dental work that is used to correct and improve the appearance of your smile.

There are a number of smile issues that cosmetic dentistry can fix. Cosmetic dental problems don’t necessarily affect your oral health, but they can have a huge impact on your appearance, “smile” confidence and emotional well-being.

The following include the most common cosmetic dental problems that dentists treat:

  • Tooth stains and discolouration

    Teeth whitening is by far the most common cosmetic dental treatment that people seek to brighten their smile. However, this treatment is mostly suitable for extrinsic or superficial stains caused by long term consumption of certain foods and beverages that stain your teeth. On the other hand, intrinsic stains are usually caused by certain meds and aging, and are deeply embedded in teeth. These require cosmetic options such as veneers or crowns.

  • Teeth spaces

    Spaces between teeth may develop due to developmental or tooth drift problems. This can cause a smile to look uneven and draw attention to the gap. Orthodontic treatments, such as aligners or braces, are the best long term options. They require a lot of patience and potential discomfort on the part of the patient because treatment can take months or even years. For quicker results, cosmetic treatment options such as dental crowns and veneers are quite popular.

  • Misaligned and malpositioned teeth

    A smile can look uneven if your teeth aren’t in their proper positions. As above, orthodontic treatment is the best long term solution. However, more immediate results can be achieved through the use of dental bridges and veneers.

  • Missing teeth

    People tend to cover up or limit their smile if they have a missing front tooth because it’s just so obvious. That’s why tooth replacement options are important to improve the smile confidence of those missing a tooth. Your dentist can recommend the best option for your situation which may be a dental bridge, a dental implant or removable dentures (partial or full).

  • Chipped, damaged or broken teeth

    Teeth that are damaged through accident, tooth decay or wear & tear can be repaired and restored to their original function and appearance via a few dental options, including fillings, inlays, overlays and crowns.

Have you experienced tooth erosion?

Have you experienced tooth erosion?

Most people are familiar with tooth decay but not tooth erosion. Tooth erosion should not be confused with tooth decay which is a type of tooth damage caused by bacterial acidic by-products – however they are similar.

What is tooth erosion and what causes it?

Tooth erosion occurs when you lose tooth structure, namely your tooth enamel, due to chemicals. The chemicals that cause erosion are found in acidic food and drinks, or acid refluxed from your stomach.

If you consume excessive amounts of acidic food and drinks daily, then you have probably already experienced tooth erosion without realising it. For example, soft drinks can contain high amounts of citric and phosphoric acid. Sipping on them as opposed to using a straw can bath your teeth in an acid bath that can wear away your teeth continually.

Other possible causes of tooth erosion include bulimia, GI problems, certain medications and genetics.

How does your dentist measure tooth erosion?

Your dentist measures tooth erosion by comparing the thickness of enamel on each tooth. There are also other signs of tooth erosion that your dentist looks out for, including:

  • darker or yellowish discolouration of your teeth indicating the dissolving of enamel,
  • sensitivity to hot, cold or sweet foods,
  • thin or transparent front teeth tips,
  • shape changes to your teeth that can give them a concave appearance,
  • a glassy appearance on your tooth surfaces,
  • flattened or pitted chewing surfaces of your molars, and
  • the impression that your natural tooth structure appears to be sinking around a filling.

TC-dental-tooth-erosion-causes

How can tooth erosion be prevented and treated?

To prevent erosion, limit the amount of acidic foods and beverages that you consume. When you eat or drink them, do so promptly and try rinsing any residue left in your mouth with water.

As far as dental treatment goes, there’s only so much your dentist can do since enamel loss is irreversible. However, your dentist can restore an eroded tooth to protect the inner tooth structure or dentin. Try using a fluoride or desensitising toothpaste to strengthen your tooth enamel as well.

How a high-fibre diet can improve your oral health

How a high-fibre diet can improve your oral health

A new study* conducted by New Zealand researchers at the University of Otago aims to figure out why high fibre foods are good for your oral health. Previous clinical research has already established that a higher fibre and wholegrain intake is beneficial for oral health, but the Kiwi scientists now want to better understand the actual mechanism that makes it so.

How do high fibre foods benefit your oral health?

Although the links between a high fibre diet and better oral health have been recognised by a number of studies, the reasons why still need more confirmation. However, scientists have identified a few potentially beneficial mechanisms that occur when you consume foods high in fibre:

  1. Cleansing action. The fibre in high fibre foods may gently scrap and buff your tooth surfaces, removing plaque build-up in the process.
  2. Oral bacterial inhibition. Certain substances found in the bran layer of wholegrains may inhibit the growth of oral bacteria.
  3. Chewing increases saliva production. Consuming high fibre foods involves a lot of healthy chewing. This increases your mouth’s production of cleansing, anti-bacterial saliva, as well as stimulating blood flow to your teeth & gums.

What are the best high-fibre foods?

High-fibre foods refer to foods that are high in dietary fibre. To get the fibre you need, there are a number of foods that are rich in fibre, including:

  • Vegetables – Vegetables that are rich in fibre are generally richer or darker in colour but there are exceptions. High fibre veges include carrots, celery, broccoli, beetroot, leafy greens (incl. spinach, silver beet, pak choi & kale) and potatoes (incl. sweet potato).
  • Fruit – High fibre fruits include apples, oranges, pears, bananas and berries.
  • Wholegrains – Wholegrain foods that are high in fibre include intact wholegrains and finely milled wholegrains such as whole grain breads (dark rye, pumpernickel & whole wheat), oats, brown rice, wild rice, bran and barley. Choose bread with at least 3 grams of fibre per slice.
  • Beans and legumes – Try adding more lentils, peas and beans to your casseroles, soups and salads.
  • Seeds & Nuts – Watch the calories but try loading up on chia seeds, quinoa, pumpkin seeds, sunflower seeds, pistachios and almonds.

TC-Upper-Mt-Gravatt-Dental-diet-high-fibre-die

How much fibre should you eat per day?

The Heart Foundation’s recommended intake of fibre per day is 30 grams for men and 25 grams for women. Children aged between 4 and 8 years old should consume at least 18 grams. Girls aged between 9 and 18 years old should increase their intake gradually from 20 to 22 grams, while boys need to consume 24 to 28 grams. But it’s totally ok to eat more than these recommended amounts!

To simplify, this recommended fibre intake translates into:

  • approx. 4 serves of wholegrain or wholemeal foods daily,
  • approx. 5 serves of vegetables, beans or legumes daily, and
  • approx. 2 serves of fruit daily.

Clean your tongue for better oral & general health!

Clean your tongue for better oral & general health!

Keeping your tongue clean is an important part of oral health care and hygiene. Why? Because oral bacteria can build up on your tongue, just like it does on your teeth.

If excess bacteria accumulate on your tongue, you may experience halitosis or bad breath. But that’s not all. You may also be at higher risk of more serious oral health complications, such as oral infections, periodontal disease and lung infections.

Daily tongue cleaning reduces your risk of gum disease (periodontal disease)

Cleaning your tongue is very important if you want to reduce pathogenic tongue bacteria. Take Fusobacterium Nucleatum for example. It is a highly invasive bacterium that causes periodontal (gum) disease.

F. Nucleatum feed off fermenting carbohydrates and cause dental plaque. These microorganisms live quite comfortably in the mucus on your tongue. They can proliferate into huge colonies within tongue mucus, which can contain 100s of millions of these nasty rod-shaped critters. Now imagine brushing your teeth, but not your tongue.

What happens next?

As soon as you put down your toothbrush and close your mouth, your bacterially coated tongue is going to redeposit millions of bacteria straight back onto the teeth you’ve just cleaned! F. Nucleatum can also infect the head, neck, chest, lungs, liver and abdomen if given the opportunity.

Tongue cleaning may help prevent lung infections

Tongue cleaning is a crucial part of a general health routine to help prevent pathogenic bacteria from spreading to the rest of your body. Many previous clinical studies have shown that you can inhale aspirated oral bacteria from your mouth straight into your lungs. This can lead to health complications if your immune system is under par.

According to a new study published by Japanese dental researchers in August 2018, a bacterial imbalance on your tongue can lead to pneumonia and other respiratory health problems – especially if you are an older adult with missing teeth, high plaque levels and more tooth decay than usual.

The Japanese researchers noted that equal attention should be given to maintaining proper oral care of the tongue, as well as the teeth and gums, for good oral health.
