Caries treatment
Caries is treated according to how far decay has entered the tooth, from fluoride care to a filling, root canal, or extraction.
The short answer
Caries treatment depends on the depth of decay: early enamel damage may be managed with fluoride and plaque control, while a cavity usually needs a filling; decay reaching the pulp may require root canal treatment or removal of the tooth.
What is the direct answer?
What does this question mean?
Caries is tooth decay caused by acids produced when plaque bacteria use sugars. The process can soften enamel first, then form a cavity in dentine and irritate the pulp, which contains nerves and blood vessels.
What can you do next?
Arrange an examination with dental X-rays when the depth is uncertain. A dentist may apply fluoride to an early lesion, remove softened tooth tissue and place a composite or amalgam filling, or clean and seal the root canals when the pulp is infected.
When should you seek dental care?
Book care promptly for a persistent toothache, sensitivity that lingers after hot or cold drinks, a visible hole, swelling, or pain on biting. Facial swelling, fever, difficulty swallowing, or difficulty breathing needs urgent dental or medical attention.
What should you ask the dentist?
Ask whether the lesion is active and how close it is to the pulp, whether an X-ray is needed, and which material suits the tooth. Also ask how much sound tooth will be removed and how to prevent new decay around the restoration.
Frequently asked questions
Can a cavity heal on its own?
A formed cavity cannot grow back, but early enamel mineral loss may be arrested or repaired with fluoride and plaque control.
Does every cavity need a root canal?
No. Root canal treatment is considered when decay or injury has inflamed or infected the pulp; shallower decay is usually restored with a filling.
