Tooth decay isn’t just a childhood issue. In fact, many adults are surprised to discover they’re dealing with dental decay, even if they’ve had relatively few problems in the past.
At Harley Private Dental, we see firsthand how common adult tooth decay is, and more importantly, how manageable it can be with the right care. If you’re noticing changes in your teeth or you’ve been putting off a check-up, this post is for you.
In this article, we’ll break down why decay happens, what signs to look for, and how we can help you keep your smile strong and healthy at any age.
Why Do Adults Get Tooth Decay?
Tooth decay, or dental caries, occurs when acids in the mouth erode the protective outer layer of the tooth—called enamel. This often results from a build-up of plaque, a sticky film of bacteria that feeds on sugars from food and drink.
Although we often associate decay with children (thanks to sugary snacks and irregular brushing), adults face their own risk factors, including:
Dry mouth
Saliva plays a key role in neutralising acids. Many medications (including those for blood pressure, allergies, and depression) reduce saliva production.
Busy lifestyles
Skipping dental visits or relying on convenience foods high in sugar or starch can increase the risk.
Previous dental work
Old fillings, crowns or bridges can wear down or trap bacteria, leading to new decay around the edges.
Changes in diet
Even “healthy” habits like sipping fruit juice or grazing throughout the day can contribute to acid attacks on your teeth.
