What causes tooth sensitivity? Is it harmful?Updated a month ago

Tooth sensitivity occurs when the tooth becomes partially dehydrated. This will trigger the nerves in your teeth, which is what is known as tooth sensitivity. Your teeth will naturally rehydrate themselves and tooth sensitivity will go away. 

Tooth sensitivity is not harmful and it is not permanent, however, it can be unpleasant! Our Cool Blue Desensitizing Pen will completely eliminate the discomfort associated with tooth sensitivity!
