Frequently Asked Questions (FAQ) for Sensitivity

The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.

Tooth sensitivity is usually a sharp intermittent zinging pain in response to cold air or food or drinks that are especially hot or cold or very sweet or sour. If you’re experiencing pain that is more severe and more constant, chances are it’s a different kind of mouth pain.

As the gums pull back, dentin becomes exposed and your teeth become less protected from sensations like hot and cold. While sensitive teeth don’t necessarily look that different, sensitive gums will turn red and may bleed. Unlike sensitive teeth, sensitive gums may not hurt that much at all. But the longer you ignore them, the worse for your teeth, so see your dentist as soon as possible.

One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets.
