Does periodontitis require a root canal?
Periodontitis typically does not require a root canal unless the infection has spread to the tooth’s pulp or nerve tissue.
Key Points to Consider:
-
Periodontitis affects the gums and bone, not the tooth pulp.
-
Root canals are performed when the tooth pulp is infected or damaged.
-
In some cases, both periodontal treatment and a root canal may be needed.
-
Early diagnosis helps determine the appropriate treatment.
-
Coordinated care between periodontists and endodontists is sometimes necessary.
When Periodontitis Leads to Root Canal Treatment
How Gum Disease Affects the Tooth
Periodontitis is a severe gum infection that damages the soft tissue and bone supporting the teeth. It usually begins at the gum line and works its way down to the bone, often without directly affecting the inside of the tooth. However, if bacteria from the periodontal pocket reach the pulp, a root canal may become necessary.
When a Root Canal Might Be Required
In rare cases, periodontal infections can spread deep enough to impact the tooth’s nerve. If this happens, symptoms like severe pain, abscesses, or sensitivity to hot and cold may appear—indicating the need for a root canal. Dentists will evaluate both the gums and the tooth’s condition before deciding on treatment.
Choosing the Right Treatment Path
Role of the Dental Specialist
Your general dentist or periodontist will assess whether the infection is limited to the gums or has affected the tooth structure. If the pulp is healthy, periodontal treatments like scaling, root planing, or surgery will suffice. A referral to an endodontist may be made if a root canal is suspected.
Preventive and Ongoing Care
Maintaining good oral hygiene and scheduling regular dental visits can prevent periodontitis from progressing and involving the tooth pulp. Early treatment can stop the infection from reaching the tooth’s nerve and eliminate the need for a root canal. Prevention is always more effective—and more comfortable—than late-stage treatment.
