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.

Where can I get tooth decay treated in Dubai?
General dentist Dr. Fariba Alnoory treats tooth decay at Manhal Medical Center in Dubai, usually with tooth-coloured composite fillings for small to medium cavities. Deeper decay that reaches the nerve may need root canal treatment with Dr. Manhal Helfawee, and large cavities may need an onlay or crown. Early treatment is simpler and keeps more of the natural tooth.
Do cavities on baby teeth need fillings?
Often yes — Dr. Fariba Alnoory at Manhal Medical Center in Dubai fills cavities in baby teeth when they are likely to cause pain or infection before the tooth falls out naturally. Very early decay may be managed with fluoride and diet changes instead. Many baby molars remain until around age 10–12, so they are worth protecting.
What are the early signs of a cavity?
Early cavities often cause no pain, which is why Dr. Fariba Alnoory at Manhal Medical Center in Dubai relies on check-ups and X-rays to find them. Later signs include sensitivity to sweet or cold, a visible dark spot or hole, food trapping or pain on biting. Throbbing pain or swelling means the decay may have reached the nerve.

I had an excellent experience with Dr. Fariba. She is an amazing dentist—very professional, gentle, and caring. She took the time to explain every step of the treatment and made sure I felt comfortable throughout the procedure. Her clinic is clean, modern, and welcoming, and her staff are always friendly and helpful. I'm very happy with the results and truly appreciate her attention to detail. I highly recommend Dr. Fariba to anyone looking for a skilled and compassionate dentistDr Fariba is the one dentist I keep going back to, because she is honest, kind, gives advice on making teeth last…Like many people, I don't enjoy the dentist. For many years I avoided visits out of fear. I found Manhal 15 years ago, and he is a wonderful dentist. Calming presence. Excellent implantology as well as other dental work. I have recommended him personally to many friends, and will continue to do so. I just hope he doesn't ever retire. When I have been overseas with dental problems, I have flown back to Dubai specifically to see him. Could not imagine ever going to another dentist.
