People with sensitive teeth may feel a twinge of pain when they eat hot or cold foods or when they drink sweet, acidic, or alcoholic beverages. The pain is caused by nerve endings exposed when the teeth' enamel wears down. There are several things that people can do to treat sensitive teeth. First, it is essential to avoid tooth brushing too hard, which can wear down the enamel. In addition, people can use toothpaste designed for people with sensitive teeth. These toothpaste often contain ingredients that help to block the pain signals from the nerves. Finally, people can talk to their dentist about getting a fluoride treatment, which can help to strengthen the enamel and make the teeth less sensitive. People with sensitive teeth can enjoy eating and drinking without pain by taking these steps.
