It's common to present sensitivity in the teeth. The tooth sensitivity it produces generally when the dentin, which is the part that is under the glaze or protective layer of the tooth, becomes exposed.
The sensitivity in the teeth may be generated by gradual loss of the enamel, by retraction of the gums, when you have tooth decay, or when one of the teeth to fracture.
It's also possible to generate sensitivity if you have any habit as bruxism, if you eat a lot carbonated water, lemon, or ice. Sometimes it can be submitted sensitivity if you're using a very abrasive toothpaste. If you have recently made a teeth whitening or a deep cleaning it is normal to have sensitivity in your teeth for a few days.
