There are many causes of tooth sensitivity, but the most frequent reason is root exposure caused by gum recession. When gums pull away, or recede from the tooth surface, the tooth's root is exposed in the mouth. This part of the tooth is more porous and softer than the enamel of the tooth. Desensitizers can be placed on these areas to alleviate sensitivity, and daily use of a sensitivity toothpaste at home are most beneficial. Additionally, tissue grafting procedures in Mitchell, SD can eliminate sensitivity.
