Can wisdom teeth removal help tmj if crowding is the main reason for the tmj ? would braces also help?

Crowding: Extracting your wisdom teeth may make room for ortho to unravel your crowded teeth. Ortho will help only, if in fact, uncrowding your teeth will help you tmj.

Wisdom Teeth TMJ: Tmj symptoms can be multifactorial - so a full work up would be wise. Specifically if a malocclusion, with dental arch crowding is the main culprit, then yes removing the wisdom teeth and also orthodontic treatment to improve alignment would help. Occlusal equilibration by the dentist after everything is completed would also be worthwhile to look into if necessary.

Not a cure-all: Malocclusion is usually causative or contributory to most TMJ dysfunction. Correcting the way your teeth & jaws meet & function is up to 97% effective in reducing TMJ symptoms. Removing wisdom teeth in the back does not make room for uncrowding crooked front teeth. You really need to consult with a qualified orthodontic specialist who can evaluate your problem and advise you as to alternatives.

Possibly: Need a history and thorough exam to help you with your questions. Every case is different and it may depend upon the severity of your TMJ/TMD and the wisdom teeth alignment and your other symptoms.

Not crowding: Crowding not the cause of TMJ problems. Braces unlikely. Orthodontists almost ALWAYS want to treat TMJ with braces. Patients often end up with straight teeth and same TMJ problem. See a TMJ expert.
