Root Canal Treatment in Cornwall

A toothache that lingers, extreme sensitivity to hot or cold, pain when biting, or tooth pain that wakes you at night can all signal an infected tooth. Root canal treatment removes bacteria from the infected root canal — relieving the pain and saving your natural tooth.

Patients in Cornwall with symptoms, changes, or questions related to root canal treatment may benefit from an assessment. Your dentist will review your oral health and recommend care based on your individual needs.

What your appointment may involve

Your visit begins with a review of your concerns and health history, followed by an examination and any diagnostic records your dentist considers appropriate. Findings, treatment options, likely steps, and alternatives are explained before care proceeds.

When is a root canal needed?

A root canal is recommended when the core of the tooth (the “pulp”) is inflamed or infected. Left untreated, an infected pulp can lead to severe, permanent problems: an abscess, worsening pain, or loss of the tooth. Root canal therapy maintains the health and structure of your natural tooth — avoiding extraction and the need for a denture or implant to replace it.

What happens during treatment

Treatment begins by clearing out the damaged areas of the tooth under local anesthetic, with more anesthetic available as needed for comfort. The infected tissue is removed and the inside of the tooth is disinfected. The root canals are filled with a rubber-like material and the opening is sealed with a temporary filling. At the next visit, the temporary filling is replaced with a core buildup, and the tooth is finished with a permanent filling or a crown.

Does a root canal hurt?

Local anesthetic is used to manage comfort during treatment. Experiences vary, and tenderness afterward can occur. A follow-up visit may be recommended to assess healing and plan the final restoration.
