Have semi crowded teeth and i want braces or invisalign, do i need to get some removed beforehand?

Ortho consult 1st: That will be up to the orthodontist to decide after you have gone for a consultation and all the records taken. This usually includes a complete clinical examination, x-rays, periodontal evaluation and study models. While sometimes it will be obvious to the orthodontist on your initial visit, most of the time the orthodontist needs to carefully evaluate all records before making that decision.

Usually no: The tendency now in orthodontics is to expand the back teeth to generate more room or circumference. It is highly unusual to have to have any teeth removed. Knock on wood I have not had to remove any teeth on any invisalign patient over the past 8 years. Straighter teeth are easier to maintain and healthier for your supporting gums and bone.

See Orthodontist: As long as the tooth-size to bone-size ratio permits, teeth can be straightened without extractions, better with braces (95% effective), about 41% effectiveness with clear aligners. If bone size inadequate non-extraction treatment can adversely affect bone support. Please see a qualified orthodontic specialist for evaluation.

Consult a doc: It depends on your case. I would actually see 2 board certified providers, assess their plans and costs, and chose one to work with.

Ask your doctor: Orthodontists create space for crowded teeth by expansion of dental arches, uprighting or tipping teeth, recontouring teeth, or tooth extractions. In cases of minor crowding, a combination of the abovementioned procedures can prevent the need for tooth extractions. The doctor treating your case is in the best position to evaluate your needs and advise you on the best approach.
