Tooth sensitivity can occur when the gum tissue covering the underlying roots of the teeth are lost. This process known as recession is part of the aging process. It can, however, be due to periodontal disease which your dentist can determine. Tissue abrasion and loss can be caused from over-aggressive toothbrushing. Clenching and grinding teeth known as bruxism can also weaken the enamel at the gumline exposing the underlying tissue. Regardless of the cause, the recession at the gumline allows the underlying dentin and nerve endings to be exposed which allows food and drink to be in contact with porous areas of the tooth resulting in sensitive nerves. To manage the sensitivity, we recommend sensitivity toothpaste or prescription high fluoride toothpaste for temporary relief. Speak to your dental hygienist and dentist about addition procedures to reduce sensitivity.
