I have this one tooth on the top row that's behind another tooth. Would I need braces to fix that? (photo)

You have beautiful teeth! With the limited information (one photo) it looks like you can fix your crossbite with a simple arch development appliance. The appliance would be removable but would need to be worn at least 12-17 hrs/day to be effective. Look for a dentist or orthodontist who treats patients with ADULT arch development.Good luck!

Hi there, Your Upper teeth should ideally be seated in front of your lower teeth around the entire arch length, if a tooth doesn't follow this rule it is called a Crossbite. This interference can be resolved with braces, or a good Invisalign practitioner may be able to tackle this discrepancy. Visit a platinum Invisalign provider if you wish to go ahead with that option. Good Luck!

Your upper left canine is in crossbite. This can be corrected with comprehensive orthodontic treatment. Please make an appointment with an orthodontist for evaluation.
