How Does Mouthwash For Sensitive Teeth Work?

According to the Ontario Dental Association at home treatments such as fluoride rinses and desensitizing toothpastes can help with tooth sensitivity. Mouthwashes desensitize teeth in two major ways: by applying solutions that anaesthetize the delicate tubules in the underlying dentin area of the teeth, and by coating your tooth enamel with materials that reinforce it and make it stronger. These strengthening compounds also fill in these microscopic tubules that lead into the inner tooth pulp through the dentin that lies below tooth enamel. Results don't occur overnight, however. It takes regular use to build up the anaesthetizing effect and strengthen the tooth enamel.

It can be difficult to decide whether to use a mouthwash or a toothpaste to treat your sensitivity, but research suggests both are equally effective. In 2013, The Journal of Dentistry published a study comparing one mouthwash containing arginine and sodium fluoride with an ordinary mouthwash without any active ingredients. Thirty patients were divided into two groups of fifteen: One group brushed twice a day using a toothpaste containing 5 percent potassium nitrate ; and the second group rinsed twice a day with a mouthwash containing 3 percent potassium nitrate. The second group also used a non-fluoridated toothpaste. Tooth sensitivity was measured after two and four weeks. Both groups experienced a significant desensitizing effect, and there was no difference between the two groups which provided a benefit in decreasing tooth sensitivity. If you have sensitive teeth, you can use a specialty mouthwash, or a toothpaste for sensitive teeth, or both.

Sensitive teeth may be a sign of serious dental problems, so always mention any sensitivity to your dentist or hygenist. They can check the source of your discomfort and offer in-office treatments. In the meantime, you can trust a mouthwash for sensitive teeth to provide you relief from current pain.
