Why cavities can be silent
Tooth decay starts in the enamel, the hard outer layer of the tooth, which has no nerves. A cavity can grow for months before it reaches the softer layer underneath and starts to cause sensitivity or pain. That is why regular exams and X-rays matter: they find decay while it is still small.
Signs to watch for
- Sensitivity to sweets, or to hot or cold food and drinks
- A toothache, or a sharp pain when you bite down
- A visible pit or hole in a tooth
- White, brown or black spots on the surface of a tooth
- Food that keeps catching in the same spot between two teeth
- A rough edge your tongue keeps finding
None of these is proof of a cavity on its own, but any of them is a good reason to have the tooth checked.
Why it’s worth acting early
Cavities detected early can be resolved with a simple filling. If decay keeps going, it can reach the nerve in the center of the tooth and cause an infection, and the treatment becomes a root canal and a crown. Left long enough, a tooth may not be savable at all.
What treatment looks like
For most small and medium cavities, we remove the decay and fill the tooth with a tooth-colored composite filling that bonds to the tooth and blends in with your smile. The appointment is usually quick, and the area is numbed first so you stay comfortable.
