Cavity treatment
Dental cavities are holes in teeth that are developed from tooth decay and are normally accompanied by discoloration on your tooth’s surface and a painful sensation. When you eat or drink bacteria in your mouth digest the food particles and create acids that can damage the enamel of your teeth and create a cavity.
If a cavity is untreated, it can lead to toothaches, infection, and even the loss of your tooth. Proper brushing, flossing, and dental cleanings can prevent cavities.
Regular checkups can identify cavities at an early stage and before they lead to serious problems.

How to treat a dental cavity?
Filling:
When decay progresses at an early stage, the most common treatment your dentist will take is fillings. Your dentist will drill out the decayed part and fill the hole with special material. Dental fillings are made of silver amalgam or composite resin.
Crown:
When too much of the tooth structure is lost, your dentist might opt for crowns, and try to save what’s left of the tooth.
Root canal:
When tooth decay goes too deep and damages the nerves of the tooth, it’s not possible to treat it with a filling or a crown. In this case, your dentist may suggest a root canal treatment and place a crown over the affected tooth.
Extraction:
Tooth extraction is usually the last option when the damaged tooth can’t be saved with other treatments. A tooth extraction will leave an empty space between your teeth, which may be resolved by inserting a partial denture, bridge, or implant.

Frequently Asked Questions
What is a dental cavity?
A dental cavity is a permanently damaged area of a tooth caused by tooth decay. Cavities develop when bacteria in the mouth feed on sugars and starches, producing acids that gradually wear away the tooth enamel. If left untreated, cavities can become larger and lead to pain, infection, or even tooth loss.
When do I need a dental filling?
A dental filling is recommended when tooth decay is detected before it reaches the inner nerve of the tooth. Your dentist removes the decayed portion of the tooth and fills the area with a durable material, such as composite resin, to restore the tooth’s strength, function, and appearance.
How much does cavity treatment cost?
The cost of cavity treatment depends on the size of the cavity, the type of treatment required, and your dental insurance coverage. A simple filling generally costs less than a dental crown, root canal treatment, or tooth extraction. Your dentist will examine your tooth and provide a personalised treatment plan and cost estimate.
What are the signs and symptoms of a cavity?
Common signs of a cavity include:
- Tooth sensitivity to hot, cold, or sweet foods
- Toothache or pain when biting
- Visible holes or pits in a tooth
- Brown, black, or white spots on the tooth
- Food getting trapped in a tooth
- Bad breath caused by decay
Some cavities cause no symptoms in the early stages, which is why regular dental check-ups are important.
Can a cavity heal without treatment?
No. Once a cavity has formed, it cannot heal on its own. Although early enamel damage may sometimes be slowed or remineralised with fluoride, an actual cavity requires professional dental treatment. Delaying care allows the decay to progress and increases the risk of more complex procedures.
