Cavity treatment
Dental cavity treatment in Casablanca
Tooth decay is the most common dental disease. It starts as a simple demineralisation of the enamel and, untreated, spreads to the dentine and then the nerve, causing pain, abscesses and sometimes tooth loss. The earlier it is treated, the simpler the treatment. At the Smiles & Beyond centre, cavities are detected at check-ups and treated conservatively.
Why treat a cavity without waiting?
A small cavity is often painless, which is why it is left to progress. But it does not heal on its own. Once it reaches the nerve, a root canal or even a crown is needed; untreated, an infection (abscess) can appear with pain, swelling and sometimes fever. Early treatment means fewer visits and better preserves the tooth.
How is a cavity treated?
The dentist removes the decayed part under local anaesthesia, then rebuilds the tooth with a tooth-coloured composite (filling). For a large cavity, an inlay-onlay or crown may be preferable. If the nerve is affected, a root canal is done first. X-rays reveal cavities between teeth or under old restorations that cannot be seen by eye.
Preventing cavities every day
Brush twice a day with fluoride toothpaste, clean between teeth, limit snacking and sugary drinks, and have regular check-ups and scaling. In children, fissure sealants and fluoride can help: the dentist advises according to risk.
Warning signs
A white, brown or black spot on a tooth, sensitivity to cold, heat or sweets, pain when chewing, persistent bad breath, food always trapped in the same place, or a swollen gum. With severe pain or swelling, consult quickly: emergency appointments are available.

How the treatment works
Examination and X-rays

Prevention
Personal brushing and diet advice, check-up schedule adapted to your risk.
Frequently asked questions
Does cavity treatment hurt?
It is done under local anaesthesia, so you should not feel pain. Slight sensitivity may last a few days.
Can a cavity heal on its own?
The very first demineralisation can sometimes be stabilised with fluoride and hygiene, but an established cavity does not heal and must be treated.
What if a cavity is very deep?
See a dentist quickly. Depending on the nerve, a root canal may be needed, followed by a restoration or a crown.
Should baby teeth be treated?
Yes, a cavity in a baby tooth can cause pain and infection and affect the permanent tooth. This is part of children’s dentistry.
