Mouthwash or Toothpaste?
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 2012, Journal of Clinical and Experimental Dentistry published a study comparing a mouthwash and a toothpaste that contained sodium fluoride and potassium nitrate. 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. He 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.
