Dental question about taxonomy:condition:cavities
A cavity is a permanently damaged area of tooth caused by acid from plaque, and treatment depends on how far the damage has spread.
What is a cavity and how far can its damage spread?
A cavity is a permanently damaged area of tooth caused by acid from plaque, and treatment depends on how far the damage has spread.
How do plaque bacteria dissolve minerals from enamel?
Bacteria in plaque use sugars and release acids that dissolve enamel minerals. Early mineral loss may appear as a white spot, while a true hole can extend through enamel into dentine and eventually the pulp.
What can you do each day to limit cavity progression?
Brush twice daily with fluoride toothpaste, clean between the teeth, and limit repeated sugary drinks or snacks. A dentist may use fluoride for early mineral loss, a filling for a cavity, or pulp treatment when infection reaches the nerve tissue.
Which signs mean a cavity needs dental care?
Arrange care for sensitivity, toothache, a visible hole, a broken edge, food trapping, or a darkening area. Facial swelling, fever, or difficulty swallowing needs urgent assessment.
What treatment options should you ask about for this lesion?
Ask whether the lesion is active, how deep it is, and whether a filling, fluoride treatment, or pulp treatment is appropriate. Ask how the tooth will be restored and how to prevent another lesion.
Frequently asked questions
Can a cavity heal on its own?
Early mineral loss may be arrested or repaired with fluoride and plaque control, but a formed hole cannot rebuild without restorative treatment.
Why does a cavity hurt with cold?
Cold can stimulate fluid movement in exposed dentine or irritate a pulp affected by advancing decay.
