Many people suffer from tooth sensitivity. It can be very mild to severe enough that you shy away from cold drinks and ice cream. An easy treatment to try is using a toothpaste for sensitive teeth. Most of these over the counter toothpastes contain an active ingredient named potassium nitrate. The potassium nitrate is absorbed through microscopic tubes in the tooth and calms the nerve of the tooth reducing or eliminating the sensitivity.
Toothpastes for sensitive teeth may take regular use for two to four weeks before you see a dramatic reduction in your symptoms. Since the toothpaste is working topically, or do to it’s physical exposure to the teeth your symptoms will return if you stop using it. I do recommend using the sensitive toothpaste every time you brush during the day and not alternating with a regular toothpaste as this will lessen the effectiveness.
There are many brands of toothpaste for sensitive teeth on the market and they all work. Make sure the one you chose contains fluoride and then pick based on flavor or brand preference.
