Do you avoid cold foods and drinks because the cold sensitivity hurts your teeth? Tooth cold sensitivity should not be ignored, because it may be caused by something that needs to be fixed right away.
Sometimes, cold sensitivity is caused by the root of the tooth becoming exposed after gum recession. The root does not have the same protective coating as the rest of our teeth and this causes the sensitivity. Talk with your dentist about some home care remedies. Some of these are as easy as always using a soft bristled tooth brush or using a special toothpaste.
Cold Sensitivity Due to Nerve Damage
Lingering cold sensitivity can also be cause by a diseased nerve in your tooth and may require a root canal. When your tooth nerve begins to die, it does not respond to cold like it should. Cold testing inspects proper tooth nerve function. Often, a refrigerant sprayed on a cotton pellet is placed on a tooth to test normal function. A healthy tooth nerve will feel sense slight discomfort from the cold and will return to normal when the cold pellet is removed. A diseased tooth will have a hypersensitive, lingering response to cold or may have no sensation at all. This sensitivity requires root canal treatment by an endodontist to help you return to full oral health.
