Common signs include lingering pain with hot or cold, pain on biting, a persistent deep ache, a darkening tooth, or swelling near the gumline. Diagnosis requires an examination and X-ray — some teeth needing treatment have no symptoms at all.
The tooth is numbed, an opening is made, the inflamed or infected pulp tissue is removed, and the interior is cleaned, shaped, and sealed. Most patients describe the experience as similar to having a filling placed.
A tooth that has had root canal treatment has lost internal structure and becomes more brittle, particularly a back tooth that takes chewing load. A crown placed afterward protects it from fracture and is usually part of the treatment plan from the start.
Untreated pulp infection does not resolve on its own. It can progress to an abscess, spread into surrounding bone, and eventually make the tooth unsalvageable. Swelling accompanied by fever or difficulty swallowing needs urgent attention — call the office immediately.
The pulp is the soft tissue at the center of the tooth, containing the nerve and blood supply. Root canal treatment removes pulp tissue that has become inflamed or infected, then seals the space—relieving pain while keeping the surrounding tooth structure intact.
Retreatment of a previous root canal, teeth with unusually complex canal anatomy, and cases requiring surgical apicoectomy are referred to a specialist. Dr. Gill will tell you upfront which category your tooth falls into.
