Dental question about taxonomy:condition:cavities
A cavity is a local loss of tooth mineral caused by acids from bacterial plaque; a dentist removes damaged tissue when needed and restores the tooth.
What happens when acids create a cavity in a tooth?
A cavity is a local loss of tooth mineral caused by acids from bacterial plaque; a dentist removes damaged tissue when needed and restores the tooth.
Why can exposed dentine make a tooth feel sensitive?
Enamel is the hard outer layer; dentin lies beneath it and can become sensitive when exposed. Plaque bacteria use fermentable carbohydrates and produce acids that dissolve mineral.
What treatment may a cavity need at its current stage?
Small lesions may be managed with preventive care, while cavitated or deep lesions may need a filling or pulp treatment. Can a cavity heal after it forms a hole?
When can early tooth mineral loss need dental care?
Early mineral loss may be arrested or remineralized, but a true cavitation cannot be rebuilt by brushing alone. Arrange dental care promptly when symptoms persist, recur, or interfere with eating, sleep, or normal mouth function.
What should you ask about the cavity diagnosis and options?
Ask which findings support the diagnosis, which clinical steps are proposed, and what alternatives or follow-up are appropriate. Ask what change should prompt an earlier review.
