Dental question about taxonomy:condition:cavities
A cavity is tooth decay: acids made by plaque bacteria remove minerals from enamel and can form a hole that reaches dentin or the pulp.
What is a cavity and how does tooth decay form?
A cavity is tooth decay: acids made by plaque bacteria remove minerals from enamel and can form a hole that reaches dentin or the pulp.
What does a cavity mean for the tooth structure?
A cavity is a localized defect caused by demineralization of tooth enamel and dentin. Plaque bacteria use fermentable carbohydrates and produce acids, which soften the tooth before a visible hole, sensitivity, or pain develops.
What can you do when early mineral loss is found?
Early mineral loss may be reversible before cavitation. A filling removes diseased tissue and seals the defect.
When should you seek care for possible tooth decay?
Fluoride toothpaste helps protect exposed enamel. Arrange an examination if the problem persists or interferes with eating, sleep, or normal oral care.
What should you ask about the cause and treatment?
Ask what finding explains the symptom, whether the tooth or gum needs testing, and which treatment addresses the cause. Share medicines, pregnancy status, allergies, and relevant medical conditions.
Frequently asked questions
Can a cavity heal on its own?
Very early mineral loss may be managed with fluoride and plaque control, but a formed cavity does not grow new enamel.
Why can a cavity hurt with sweets?
Sweet exposure can move fluid through dentin tubules and stimulate an irritated pulp.
