What is tooth sensitivity? Tooth sensitivity is tooth pain caused by wear and tear on the tooth surface or gum tissue. The most common cause of tooth sensitivity in adults is the exposure of tooth roots due to gum recession. As the roots of the teeth lose their enamel protection, thousands of tiny holes appear in the teeth, exposing the nerve center (pulp) of the teeth. This causes pain when the tooth is exposed to cold, heat or pressure. If left unattended, this can lead to other oral health problems. Because of tooth pain, brushing can be done with less effort, which can lead to cavities and gum disease in particular. How do I know if I have tooth sensitivity? If you experience tooth pain when eating hot or cold foods or drinking hot or cold beverages, you may have tooth sensitivity. Tooth sensitivity is not uncommon. One in four adults has tooth sensitivity, and it is often recurrent. How to treat tooth sensitivity? The first step is to seek help from a dentist or health professional. Tooth sensitivity can usually be cured. Your dentist will prescribe a fluoridated brushing gel or fluoride mouthwash. You can also try a mildly abrasive toothpaste for sensitive teeth. You can consult your dentist to see which anti-sensitivity product is right for you. It is important to brush your teeth the right way, otherwise your teeth will wear down and cause tooth sensitivity. Excessive force when brushing, improper wearing of denture clasps or braces can lead to tooth (surface) wear.
