Root canal treatment

Teeth and molars have roots with which they stand in the bone, These roots are hollow inside for the nerve and blood supply of your molar. When a cavity or filling gets too close to the nerve, or there is trauma, such as a fall, a nerve can be damaged and sometimes die as a result. Inflammation products then form in the molar and around the root tip, which can cause symptoms such as sensitivity when hot and cold, swelling or nagging spontaneous pain, or pain when pressure is applied to the molar as when chewing or tapping.
