What is a root canal?
It is a procedure in which we repair and save your tooth by removing the nerve. It is typically needed when there is a deep cavity affecting the pulp or from a trauma that has damaged the nerve of the tooth. Your symptoms might be sensitivity to hot or cold, sweets or pressure. You may also have swelling and pain that can stem from an infection. The roots of your tooth stay intact while the nerve is removed which is the cause of the pain and infection.
Will it hurt?
Most patients don’t feel any pain or discomfort as root canal treatment is very similar to having a filling done. The only reason you might feel discomfort is if there is infection present causing the freezing not to take. When needed, the doctor prescribes you antibiotics to take prior to having this treatment completed.
Will this prolong the life of my tooth?
After the root canal is complete the tooth is no longer vital and will be at a higher risk of fracturing and breaking. The doctor will likely recommend a crown for your tooth once the root canal is complete and the infection is completely gone to prolong the life of the tooth.
Should I just pull my tooth instead?
While removing your tooth is a faster, less expensive method of treatment, we do find that most people often regret having the tooth removed. They usually miss that tooth for chewing, for aesthetics, or their other teeth start shifting. Because of these issues from the tooth being gone, people often then start looking into replacement options which are considerably more expensive than if they had proceeded with the root canal treatment.
A root canal is needed to try to save a tooth that has become infected. The nerve of the tooth is removed, and is then cleansed and sealed.
A retreatment is sometimes needed when the original root canal fails. This could be due to unsuccessful healing, difficult root anatomy, or delayed placement of the permanent replacement.
An apicoectomy is a procedure that is done when a root canal is not possible. The very bottom tip of the root is removed and sealed.
A pulpectomy is the removal of the pulp chamber from the upper portion of the tooth. This can be done to alleviate pain as an emergency procedure prior to having the root canal completed.
A root amputation is done to maintain the healthy portion of the roots by only removing the damaged roots.

Using a microscope in the dental field has many benefits, including being able to see the tiniest details of a tooth. Endodontists often use microscopes during treatment to allow them to navigate the canals of the tooth, helping to maintain as much of the tooth structure as possible.
A CBCT scan (cone beam computed tomography) is a special type of 3D x-ray that is taken when more information is needed than can be obtained from a regular 2D x-ray. This scan is able to produce images of not only your teeth, but your tissues, nerves, and bone. A CBCT can be taken for surgical planning of impacted teeth, diagnosing TMJ, to determine the accurate placement of implants, and to locate the nerves for root canal treatment.
