Tooth Resorption: Why the Exact Type Changes the Treatment Discussion

If a dentist has told you that a tooth has resorption, ask for the exact diagnosis before trying to understand the treatment proposal. Bring the report to the conversation and ask the clinician to point out the finding on the images.

This guide is for discussing a clinical finding. It does not identify the type from a photograph, tooth colour or symptoms.

Ask where the process is occurring

Internal root resorption involves tissue bordering the pulp chamber or root-canal space. External resorption includes different processes affecting the outside of the root, including inflammatory, replacement, pressure and cervical forms.¹

Ask the dentist which term applies to your tooth and how it was established. If the report uses more than one unfamiliar word, request a plain-language explanation of each. Write down what is known and what the clinician still needs to assess.

You could say: “Please explain where the resorption is and what makes this the type you have identified.”

Find out why the proposed treatment fits

Pressure resorption is not caused by disease of the pulp, so root-canal treatment is not indicated for that process. Other forms can involve the pulp and require a different treatment discussion.¹

Ask what the proposed treatment is intended to address in your case. If root-canal treatment has been mentioned, ask why it is being considered for this tooth. If surgery, monitoring or removal is discussed, ask the clinician to explain the reasons and alternatives.

You could say: “What problem would this treatment address, and what would it leave for us to monitor?”

Discuss how much tooth can be restored

The AAE explanation describes treatment of external cervical resorption in relation to whether the tooth is restorable and whether the pulp is involved. It also describes monitoring as a possible option for some extensive lesions.¹

Ask what the findings mean for your tooth’s outlook and what could make the recommendation change. If the clinician is uncertain about an option, ask what further assessment would help. Request an explanation of the expected benefits and limits before agreeing to a procedure.

Keep the follow-up question specific

Ask when the tooth should be reviewed, what the clinician will look for and which changes should prompt you to contact the dental team sooner. If you are referred to a specialist, check who will arrange the appointment and which reports or images will be shared.

At the review, return to the exact diagnosis and the purpose of the plan. Ask whether the findings have changed and how that affects the next step. Keep the report and the written instructions together.
