Tooth decay and cavities — signs, treatment and prevention
Cavities often cause no pain until they are large. Regular check-ups and X-rays find them while treatment is still simple.
Tooth decay starts as softening of the enamel and becomes a cavity as it spreads into the dentine. Early decay can sometimes be stopped with fluoride; cavities are treated with tooth-coloured composite fillings, while deep decay may need root canal treatment or a crown.
Key facts
- Often painless until advanced
- Tooth-coloured composite fillings
- Deep decay may need root canal
- Check-ups catch decay early
Signs of decay
Sensitivity to sweet or cold, food catching in a tooth, dark spots or holes, and later toothache.
Treatment by stage
Early lesions: fluoride and monitoring. Cavities: composite fillings. Deep decay: root canal treatment and a crown.
Preventing new cavities
Fluoride toothpaste, fewer sugary snacks and drinks between meals, cleaning between teeth and six-monthly check-ups.
Composite fillings repair cavities with resin matched to your tooth colour. They bond to the tooth, allowing a more conservative preparation than old metal fillings.

Questions patients ask
Patients visit us from Al Safa, Al Wasl, Jumeirah, Umm Suqeim, Al Quoz, City Walk, Business Bay, Downtown Dubai and Al Barsha — and from Sharjah and the wider UAE.
Can a cavity heal by itself?
Early enamel softening can remineralise; a true cavity needs a filling.
Are white fillings strong?
Modern composites are strong for most fillings; very large ones may need an inlay or crown.
Why do I get cavities even though I brush?
Diet, saliva, gaps between teeth and dry mouth all play a role.
Can old amalgam fillings be replaced?
Yes, when they are failing or for appearance, after discussion.
