Inside and deep within our teeth is a secret chamber. These chambers hold the blood and nerve supply coming in from the bottom of the teeth. They remain a secret while the cavities which are on the surface grow into the depth of the tooth.
Once harmed our teeth become extremely sensitive to any stimulations: Biting forces, cold, hot, sweet, and at times they just HURT. What can relieve these pain? Root canal treatment or removal of the tooth. If the tooth is determined to have sufficient bone supply for stability, root canal treatment is the treatment of choice. The secret chamber is filled with a medication that restores you to your former painless state.
