Thanks for putting up your question on Just Answer.
You can try a special tooth paste called sensitivity
toothpaste like Sensodyne or Duraphat. They are available at a pharmacy and do not require a prescription. Use it daily with warm ( not hot ) water to brush your teeth. The components of these pastes will physically block the small holes in the surface of your teeth. This will decrease the sensitivity.
You might be experiencing pain
when you breathe through your mouth. To reduce this, you can cover your tooth with Vaseline petroleum jelly. This creates an insulating blanket on the tooth, sealing it off from its surroundings.
But Im afraid home remedies may not be enough to stop the sensitivity of an exposed tooth root.
I would advise you to got to a dentist
. If the exposed root area is very small, a small tooth colored filling may to the trick !
Hope this answers your question. Feel free to contact me again for more information.
I wish you a speedy recovery !!!
