Cavities are the most common dental problem we treat — and also one of the most preventable. A few consistent habits will protect your teeth far more than any single treatment.

How cavities form

Bacteria in your mouth feed on sugar and produce acid, which slowly dissolves the enamel. Left unchecked, this creates a hole (cavity) that grows deeper over time. The good news: you can interrupt this process every single day.

The daily essentials

  • Brush twice a day with a fluoride toothpaste for two full minutes.
  • Floss once a day to clean between teeth where a brush cannot reach.
  • Do not rinse straight after brushing — spit, and let the fluoride keep working.

Watch your diet

It is not just how much sugar you eat, but how often. Frequent snacking and sipping sweet drinks keeps your teeth under constant acid attack. Try to keep sugar to mealtimes, drink water between meals, and rinse after sweet or acidic foods.

Do not skip professional care

A six-monthly checkup and scaling and polishing removes hardened tartar that brushing cannot, and lets us catch early decay while it is still painless and cheap to fix. Fluoride treatments and sealants add extra protection, especially for children.

Know the early warning signs

Sensitivity to sweet, hot or cold, white or brown spots on a tooth, or mild sensitivity when biting can all signal early decay. Caught early, a small filling is quick and simple. Book a checkup at our Bhayli clinic if you notice any of these.

Frequently Asked Questions

How often should I brush and floss?

Brush twice a day with fluoride toothpaste for two minutes, and floss once a day. It is the single most effective routine for preventing cavities.

Does sugar really cause cavities?

Indirectly, yes. Bacteria turn sugar into enamel-dissolving acid. Frequent snacking and sipping sugary drinks is especially damaging because it keeps teeth under constant attack.

How often should I get a dental checkup?

Every six months for most people. Regular checkups and cleanings catch decay early, when treatment is simple, painless and inexpensive.
