“SENSITIVE” TOOTHPASTE ISN’T ENOUGH
Many toothpastes claim to treat sensitive teeth, but researchers recently found they don’t help much. A tooth grows sensitive when its protective enamel erodes, exposing dentin, a layer with tubules that lead to the nerves. The researchers tested nine “antierosive” and/or “desensitizing” products and found that they all caused enamel wear, just like regular toothpastes. Some desensitizing toothpastes might help to block pain, but you likely also need to see your dentist for other treatment options.
