Your : Your teeth may be feel painful when exposed to very hot or very cold foods or beverages because the dentin is exposed. The top layer of the tooth is called enamel. Enamel does not have a nerve supply, thus the enamel is not causing your tooth pain. The layer of the tooth below the enamel is called dentin. If the dentin is exposed, this can lead to pain with temperature changes because the dentin is sensitive. How can your dentin become more exposed over time? Anything which decreases your enamel can increase dentin exposure. If you grind your teeth, you can wear down enamel. If you drink lots of sodas, the carbonic acid damages the enamel. If you have acid reflux into the mouth, it has a similar result. Brushing your teeth too vigorously can abrade away the enamel. Of course, one of the biggest concerns is if you have dental decay (a cavity). Are any of these possible reasons for the increased sensitivity of your teeth?
