One of the most common questions patients ask is:
“Wouldn’t I know if I had a cavity?”
Unfortunately, not always.
Many cavities cause no symptoms at all during their early stages.
As decay progresses, however, certain symptoms can appear.
1. Cold Sensitivity
A tooth may become increasingly sensitive to cold drinks or foods.

2. Sensitivity to Sweets
Sugar or sweet foods may trigger sensitivity in an affected tooth.
3. Food Getting Stuck
A cavity or failing filling can change the contour between teeth, allowing food to repeatedly become trapped.
4. Pain When Chewing
Deeper decay or weakened tooth structure may cause chewing discomfort.
However, cracks and other problems can produce similar symptoms.

5. A Visible Hole
More advanced cavities can sometimes create an obvious defect in the tooth.
At this point, the tooth has physically lost structure and generally cannot simply remineralize back into its original shape.

6. Toothache
As decay progresses toward the nerve, symptoms can become more significant.
Pain may become spontaneous rather than occurring only when eating or drinking.
7. Absolutely Nothing
This is perhaps the most important sign.
A cavity may not feel like anything.
That is why relying exclusively on pain can allow decay to progress significantly before treatment.
How Are Cavities Confirmed?
Your dentist may combine:
- Visual examination
- Clinical testing
- Dental X-rays
- Your symptoms
- Comparison with previous examinations

Frequently Asked Questions
Can a cavity hurt and then stop?
Symptoms can fluctuate. The disappearance of pain doesn’t necessarily mean the underlying problem has resolved.
Can you see every cavity?
No. Cavities between teeth may not be visible without appropriate imaging.
Does every cavity hurt?
Definitely not.

Don’t wait for a cavity to announce itself.
