If you have sensitive teeth, you may feel pain when your teeth are touched or exposed to hot or cold foods. The condition, called “dentin hypersensitivity,” occurs when the roots of teeth become exposed due to gum disease (the most common cause), excessive brushing, aging or tooth grinding.
Get toothpaste specifically formulated for sensitive teeth.
Use it 3 times a day or until you have noticed that it’s helped. Use a toothbrush with extra-soft bristles, and do not brush horizontally, which exposes tooth roots.
Avoid stimuli that trigger pain. Hot or cold foods like ice cream and coffee, sweet or sour foods such as lemons and candy, and acidic foods such as wine and grapefruit juice commonly cause problems for people with sensitive teeth.If it’s just from eating ice cream or something you can just gargle with warm water.
