Many people suffer from sensitive teeth: a condition in which hot and cold foods or liquids, or cold air can cause discomfort and pain.
Tooth sensitivity can be caused by cavities or infection, by excessive clenching or grinding of teeth, or by wear near the gumline. As we age, enamel often becomes thin and sensitivity increases.
Hypersensitive teeth can cause people to change their eating habits, avoid social situations, or even avoid proper oral hygiene because the simple act of brushing or rinsing causes pain. Relief can sometimes be had by using a desensitizing toothpaste, sealants, or special fillings.
