- [Exposed Roots and Sensitivity](https://why-are-my-teeth-sensitive.junegy.workers.dev/exposed-roots-sensitivity/): Exposed roots sensitivity happens when gums move back and uncover root surfaces that lack the hard enamel covering the rest of the tooth.
- [Acidic Foods and Sensitivity](https://why-are-my-teeth-sensitive.junegy.workers.dev/acidic-foods-sensitivity/): Acidic foods sensitivity comes from acids temporarily softening the tooth surface, which can leave the layer underneath easier to reach with cold, heat or.
- [Cracks and Sensitivity](https://why-are-my-teeth-sensitive.junegy.workers.dev/cracked-tooth-sensitivity/): Cracked tooth sensitivity often shows up as a brief, sharp zing when you bite down or when you release the bite, or when something hot or cold touches one.
- [When Sensitivity Needs a Visit](https://why-are-my-teeth-sensitive.junegy.workers.dev/when-sensitivity-needs-a-visit/): Mild, brief sensitivity to cold or sweets can often be watched for a short while while you adjust habits, but when sensitivity needs a visit is usually clear.
