What causes cavities and tooth decay?
Tooth decay begins when bacteria use sugars and starches to create acids that weaken tooth enamel. Over time, the weakened area can become a cavity.
Common signs of a cavity
Early tooth decay may have no symptoms. As it progresses, you may notice:
- Tooth sensitivity to hot, cold, or sweets
- A toothache or pain that starts without an obvious reason
- A white, brown, or dark spot on a tooth
- A visible pit or hole
- Pain when biting or chewing
- Food repeatedly getting stuck in the same place
