Overview
Tooth sensitivity happens when dentin or the tooth nerve is irritated. Mild generalized sensitivity may improve with desensitizing toothpaste, but one-tooth sensitivity, pain on biting, or lingering pain can signal decay or a crack.
Key Takeaways
- ✓Hard brushing and acidic drinks can worsen sensitivity.
- ✓Gum recession exposes root surfaces that are more sensitive.
- ✓Sensitivity toothpaste helps some cases but will not fix cavities or cracks.
- ✓Pain that lingers after cold needs evaluation.
What You Can Do At Home
- 1Use a soft toothbrush and avoid scrubbing.
- 2Try desensitizing fluoride toothpaste consistently for several weeks.
- 3Reduce acidic drinks like cola, citrus drinks, and frequent vinegar-based foods.
- 4Do not brush immediately after acidic foods or vomiting; rinse first and wait.
