Can root cannal can fix moving teeth?

Teeth become loose for an number of reasons, trauma, loss of bone support, inflammation of the periodontal ligament, and also from dental abcesses. If an abcess is the cause of the problem then root canal therapy will most likely help you. But you need to have this issue evaluated by a qualified dentist who can run through all the tests and advise you on how best to treat the condition.

No. Root canal treats infection of the inside of a tooth. If teeth are shifting may be due to gum disease, malocclusion, missing teeth with bite collapse, grinding and/or clenching, and other reasons. Start with an examination by the best general dentist in your area. If specialist referrals are required follow your Dentist's recommendations.
