Anyone can get cavities, but when it advances deep into the affected tooth, it can cause pain and discomfort. If left untreated, the infected tooth can suffer breakdown and further spread of infection. This is when a root canal treatment is needed.
The outer and inner layers of the teeth, enamel and dentine, are penetrated by infection and it can reach the inner pulp and roots. The pulp is where the blood vessels and nerves of the tooth reside and when this is infected, it must be removed.
Root canal treatment involves removing the infected pulp from the roots of teeth after administration of local anesthesia. The root and pulp cavity are then filled with an inert material and reinforced with the placement of a strong material or a post.
Once this is done, the tooth is then shaped for the placement of a crown, and the crown is subsequently fabricated and placed.
The dentist may also prescribe antibiotics prior to treatment in case of a severe infection and after, to prevent any spread of infection from the roots into the body.
