When you have sensitive teeth, activities such as brushing, flossing, eating, and drinking can cause sharp, temporary pain in your teeth. Sensitive teeth are typically the result of worn tooth enamel or exposed tooth roots. Sometimes, however, tooth discomfort is caused by other factors, such as a cavity, a cracked or chipped tooth, or a side effect of a dental procedure, such as bleaching.
If you are concerned about sensitive teeth, start by visiting your dentist. They can identify or rule out any underlying causes of your tooth pain. Depending on circumstances, your dentist may have multiple recommendations.
