Case Study
Swapping troubled amalgam fillings for natural-looking composites
Upgrading to a healthier, more natural smile
Ava (not her real name) visited TC Dental, concerned that her old silver fillings on her back teeth weren’t feeling right. Specifically, teeth 45 to 47 (lower right side molars and premolars) had amalgam fillings from many years ago. Over time, Ava noticed that these fillings no longer felt or looked like they should, and during her dental checkup, we found more than just outdated materials.
Old fillings and hidden decay
Amalgam (or silver) fillings were a mainstay in dentistry for decades thanks to their strength and durability. But they’re not without drawbacks. Over time, amalgam can cause tiny cracks in the tooth due to expansion and contraction with temperature changes. This can let bacteria in, making it easier for decay to develop underneath or around the old filling, which was exactly what happened in Ava’s case.
Upon examination and updated X-rays, we found that teeth 46 and 47 had visible decay beneath the old fillings. If left untreated, this decay could eventually reach the nerve of the tooth, leading to pain, infection, or even the need for root canal therapy later on.
Composite fillings for a healthier, more natural smile
Ava decided to replace her old amalgam fillings with composite (white) fillings—a popular choice for good reason. Unlike the dark, metallic look of silver fillings, composite materials are tooth-coloured and blend seamlessly with natural enamel. Not only does this improve the appearance of your smile, but it also offers excellent durability for everyday chewing.
Here’s what we did for Ava:
1. Carefully removed the old amalgam fillings on teeth 45-47.
2. Cleaned out all decay, especially in teeth 46 and 47, where the cavities had spread.
3. Rebuilt the teeth with high-quality composite material, shaped and polished to restore their natural shape and function.
A strong, healthy, and natural-looking smile
Ava was thrilled with the result. Her teeth now look just like natural tooth structure—no more dark patches when she laughs or talks. More importantly, her teeth are protected from further decay, and her overall oral health is back on track.
Why patients choose composite fillings today
More and more patients are opting to replace old silver fillings with white composite ones.
Here’s why:
- Natural appearance: Blends beautifully with your teeth
- Safe and strong: Bonds securely to the tooth, helping to strengthen it
- No more metallic look: No dark spots when you smile or open wide
- Preserves more of your natural tooth: Composite requires less removal of healthy tooth structure than amalgam
