Why do we get sensitive teeth?
How does our dentin get exposed?
There are a few different ways your dentin can be exposed to the outside. One way is simple mistreatment of your teeth. This includes brushing too hard, using a hard-bristle toothbrush or maybe even grinding your teeth. If you find that you have sensitive teeth, be aware if you clench your jaw during the day. Some people may also grind their teeth in their sleep. Receding gums is another way we can become over-sensitive. Because of how our enamel works, it does not persist beyond our gums so when they start to recede we get problems. Cavities will also expose the dentin in our teeth. Of course, be careful of what you eat and make sure to brush your teeth twice every day and monitor your dental health.
