Why is it so important to inform Australian school students about the health risks of sugar?

Short answer: Too many Australians are over consuming sugar and are experiencing serious health problems as a result.

According to the World Health Organisation (WHO), the recommended daily intake of sugar should not exceed 6 teaspoons of added sugar. However, Australians consume way over that daily amount by eating 14-16 teaspoons on average. Children and teens consume even more where the average exceeds a whopping 20 teaspoons or more.
Valium leads to the potentiation of the effects of alcohol, anticonvulsants, sleeping pills, antihistamines and hypotensive drugs, neuroleptics, tricyclic antidepressants, general anesthetics, muscle relaxants and analgesics. Valium loses its activity in combination with analeptics and psychostimulants. Antacids reduce the rate of absorption of the active substance.

The effects of high added sugar intake on your health

Eating too much sugar is a key causative factor in a number of developmental and health issues that can impact on a child throughout their entire lifetime. These include:

• tooth decay and oral disease
• brain developmental issues
• poor sleep
• learning difficulties
• obesity
• type 2 diabetes
• heart disease
• Alzheimer’s & mental health issues
• cancer

What will students be taught about sugar consumption?

The SugarByHalf school program is comprised of a number of curriculum-aligned lessons that can be integrated in science, math, HPE and English units at primary and secondary school levels.

Students are taught to understand and recognise how sugar is marketed to them, good nutrition and the health effects of long term sugary food choices. Units include:

• The social and economic impact of sugar (HASS – Grades 5/6)
• Understanding the nutrition information panel (Math – Grades 5/6)
• Body science – the science of sugar (HPE – Grades 7/8)
• The influence of advertising on sugar consumption (English – Grades 9/10)
• Sugar, acids and tooth decay (Science – Grades 9/10)

Is your child’s school teaching the Sugar-By-Half curriculum?

If the answer is no, do something about it. If you are a concerned parent or educator, you can find out more information about these free curriculum-aligned learning units at:  https://www.coolaustralia.org/sugar-by-half-landing-page/

While some lessons include practical science investigations that can only be conducted in a classroom, others are quite suitable for home learning. Future lessons are currently in development for early childhood age groups also.

However, there is one other hygiene tip that most people constantly forget – don’t touch your face!

People self-inoculate germs from fingers to face

For years, flu researchers have advised people to stop touching their faces during cold and flu season, especially if they are out in public spaces.

Everytime you touch your mouth, nose or eyes, you transfer bacteria or viruses there from whatever contaminated surface your fingers have come in contact with. This is the primary way that certain bacteria and viruses spread apart from airborne transmission.

So, even if you were to wash your hands regularly, there are plenty of opportunities to re-contaminate your hands in between when in public spaces.

Face touching – a hard habit to break

Most people touch their faces whether they know it or not. Whether it’s scratching an itch, rubbing the nose or even brushing hair off your face for a few selfies, we can’t seem to keep our hands away from our faces.

Studies have shown that we can touch our faces over 20 times per hour and may touch public surfaces 3 times an hour on average.

COVID-19 in public spaces

Public surfaces that we touch – such as shopping trolleys, self-checkout machines or public toilets – can be covered in greasy bio-films brimming with bacteria. Health experts claim that COVID-19 can survive on these types of surfaces for several hours or more.

So, the next time you wash your hands with soap for 20 seconds, try to avoid touching public surfaces and your face until the next hand wash!

Alarming rates of oral disease among athletes

However, in a study published recently by English dental researchers from University College London, it was discovered that elite athletes have significantly higher rates of oral disease than everyone else.

As hard as that is to believe, the UCL study was comprehensive and surveyed 352 Olympic and professional athletes from a wide range of sports including athletics, swimming, cycling, rugby league, soccer, hockey, rowing and sailing. All athletes in the study were given oral health checkups that included assessments for tooth decay, gum disease and tooth erosion. They were also surveyed about their oral care and hygiene habits.

Athletes scored high on oral health habits

As far as oral habits go, elite athletes scored impressive results compared to the rest of the population. On top of the 94% who brushed twice daily, 44% flossed or practiced interdental cleaning daily.

The same athletes scored low in their oral health check up

But now for the bad news! Despite all their commendable efforts to maintain their oral health, top athletes experienced alarming rates of oral disease. In the English study, researchers found that 49.1% had tooth decay that was untreated, and of those, nearly all had gum inflammation. When interviewed, 32% stated that their oral health issues had a negative effect on their performance and training.

The paradox explained by UCL researchers

Professor Ian Needlemen, who led the UCL study, reported that there were two main factors that contributed to this grim picture of oral health among the athletes. The first, was their regular use of sports drinks, energy bars and energy gels, all of which consist of sweetened refined carbohydrates. These types of foods and drinks are sticky and contribute greatly to tooth decay and erosion.

In addition, during extended periods of intensive physical activity, the athletes experienced dehydration and a dry mouth. Without adequate hydration, the acidic food and drink residue in their mouths was not being rinsed out by enough saliva.

All elite athletes need to adopt better oral health habits

In conclusion, one of the lead UCL researchers, Dr Julie Gallagher, has recommended that all elite athletes should rethink their intake of energy foods and beverages, adopt more thorough oral health habits and visit their dentist more often.

Tartar or calculus is an oral condition where a calcified build up occurs behind or outside your teeth along the gum line. Most oral health information will tell you that tartar is the end result of plaque that has hardened because it hasn’t been removed regularly through brushing and flossing.

Once tartar forms on your teeth, only your dentist can remove it during a dental clean via a nonsurgical dental procedure called scaling. This dental technique utilises a special instrument to remove tartar build up from your teeth above, along and below the gum line.

Tartar is a biomarker for calcium build-up in your body

However, whether you have experienced light or heavy tartar doesn’t mean you just have oral care and hygiene issues, it may also be a sign that you have trouble metabolising calcium.

If your body has difficulty metabolising calcium, it may be going to all sorts of places in your body, like your artery walls, joints, soft tissue and saliva. Everywhere it seems except for your bones and teeth where it’s needed most.

How do high calcium levels in your body cause tartar?

Tartar is not just made up of hardened plaque. It also contains a lot of calcium. So where does this calcium originate? It comes from your saliva. The higher the calcium levels are in your saliva, the more prone you are to developing tartar on your teeth. Unfortunately, today men are not very fond of or just afraid to carry out such experiments on their body and health, so they just take what they find first and calm down on this, even if the drug does not help solve the problem of sexual intercourse very well. Therefore, it is best to immediately stop at such a popular drug as Cialis. More information at https://tadalafilhome.com.

Why does tartar only form in certain areas of your teeth?

Tartar, or calculus, usually forms on tooth surfaces that are close to your saliva glands. The saliva glands under your tongue are chiefly responsible for tartar build-up behind your bottom front teeth, and the glands in your cheeks can affect the outside surfaces of your molars.

What are the health risks of high calcium levels in the body?

High calcium levels in your body can build up in all the wrong places which may cause a range of health issues. These include joint issues, coronary calcification, calcified arterial plaque, heart disease, tartar – and very weak teeth and bones.

There are mouthwashes and there are mouthwashes.

Some are pro-biotic, some are fluoridated to help strengthen tooth enamel, while others contain alcohol and are meant to zap all the oral bacteria in your mouth to kingdom come – or for at least 24 hours till they regenerate and the bad breath starts up again! However, it’s the latter mouthwash option that has come under increasing scrutiny and been red flagged by oral health researchers in recent years.

Should you use alcohol-containing mouthwash to eliminate “99%” of the germs in your mouth?

Maybe not. While it’s true that certain oral bacteria cause acidic plaque that should be prevented to maintain good oral health, there are other essential oral bacteria that are quite beneficial and extremely important to your oral and digestive health.

Together, this community of “good and bad” oral bacteria make up what is known as the oral microbiome. Using a mouthwash that kills 99% of oral bacteria in your mouth means that you are eliminating not just the bad bugs but the good ones as well.

Additionally, alcohol-based mouthwashes can dry out your mouth and reduce saliva which is essential for oral health.

What is the oral microbiome?

The oral microbiome is a large and diverse ecosystem of microbiota aka oral bacteria in your mouth that is second only to the gut microbiome in size. Within it are well over 700 species of oral bacteria living side by side. When your oral microbiome is in balance, your gut flora usually is also and vice-versa.

How do good oral bacteria contribute to good oral health?

When your oral microbiome is in balance, the presence of good bacteria outcompetes the pathogenic bacteria and prevents them from accumulating together en masse via plaque and dumping huge amounts of bacterial acid onto your teeth – thus causing bad breath, tooth decay and gum disease.

Additionally, beneficial bacteria can prevent pathogenic oral bacteria from reaching critical mass, after which they may start to invade your bloodstream and other parts of your body.

Good helpful oral bacterial strains include Lactobacillus salivarius, Lactobacillus reuteri, Lactobacillus brevis and A12.

Since beneficial bacteria can keep pathogenic bacteria in check, you’ll experience a reduction in:

• plaque build-up,
• gum disease inflammation,
• gingivitis,
• bleeding gums, and
• bad breath (halitosis).

Certain beneficial oral bacteria can also help prevent oral infection and oral cancer.

What causes an imbalance of good and bad oral bacteria?

Unfortunately, when your diet predominately consists of refined carbohydrates and simple sugars – i.e. sweets, pastries, white flour products and sweet drinks – bad oral bacteria can take over your oral micrbiome. Pathogenic gram negative bacteria outnumber the beneficial ones and start to wreak havoc on your teeth.

Other factors that may contribute to an imbalance of your oral flora include poor oral care, a weakened immune system, genetics and a reduced saliva flow, aka dry mouth.

Mouthwashes that may be harmful to your oral microbiome

You may take probiotics – as opposed to antibiotics – to improve your gut bacterial flora. So why shouldn’t it be any different for your oral microbiome? Essentially, alcohol-containing mouthwashes act as antiseptics and antibiotics destroying a large part of your oral microbiome indiscriminately.

The most harmful mouthwashes to your oral microbiome include ones containing alcohol, hydrogen peroxide and chlorhexidine.

The best way to rebalance your oral microbiome

Eat more fermented pre and probiotic foods, such as raw asparagus and sauerkraut, and fibre-rich vegetables, such as celery, to balance your oral and gut flora.

Include calcium rich foods in your diet such as yoghurt, soft cheeses, kefir and vegetable stalks, such as the stalks of silverbeet or broccoli. Keep in mind that the stalks of any above-ground vegetables often contain higher concentrations of calcium than the leaves or flowers.

Pre and probiotics are also available in concentrated supplements. However, people with weakened immune system should consult their G.P. if they are considering taking them.

Gentler mouthwash options

Listerine, Colgate and other producers of mouthwash are currently researching mouthwash formulas that selectively target pathogenic oral bacteria. However, these products are still in the pipeline.

Fortunately, there are a wide range of probiotic oral mouth washes and rinses available that are alcohol free. These may gentler on your beneficial oral bacteria, teeth and gums. To check out what’s available near you, just Google “oral probiotic mouthwash/mouthrinse” in their Shopping Search bar.

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.

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.

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 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.
The urology specialists of our St. Andrew’s medical center work with the erectile dysfunction patients practically every day. Usually, the therapy they choose is based on the use of one of the PDE5 inhibitors. Cialis is one of the safest and most effective of them. Our patients like this drug because of its long duration and few side effects.

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 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
