Q: My teeth are sensitive to the cold. Is there anything I can do to ease the discomfort?
A: Now that winter is here with its icy blasts of wind, many people will discover that their teeth are sensitive to the cold. The condition is sometimes called dentin hypersensitivity. Dentin is the layer of tissue under the tooth's enamel. When enamel wears down or gums recede, root surfaces are exposed. Eating or drinking hot or cold foods and liquids-and exposure to cold air-can be painful. Over a lifetime of contact with hot and cold elements, teeth also can develop microscopic cracks.
If you have a problem with sensitivity to hot or cold, see your
dentist to rule out a more serious problem like a cavity or an abscess.
If the problem is dentin hypersensitivity, your dentist may be able
to treat the problem with a sealant like cement or plastic. Fluoride
gels and special toothpastes that can help with the condition are
also available. They will block transmission of the hot or cold stimulant
to the dentin. When you experience any sort of abnormal feeling in
your mouth, your first step should be a call to the dentist.
