What are the long term teeth-health implications of IPR done over a few teeth? As part of Invisialign, to improve smile (Photo)

There are case studies that have been done on many Invisalign patients who have received IPR as a part of their treatment to determine if the IPR compromises the integrity of the natural teeth and the short answer is, no it does not. The portion of the tooth that is removed with IPR is very minimal and should not impact your oral health significantly. If you are concerned with the treatment plan given to you by your first provider, maybe it is best if you get a second opinion. 

IPR is an orthodontic thing, not an invisalign only thing.  Done properly, has no negatives and certainly beats having teeth pulled.  You have a lot more crowding on the lower than the upper and very triangular lower teeth.  That is a good situation for IPR done along with arch width expansion -- you need that to.  

Dear apparition,Thank you for posting your question on Real Self.  I will do my best to answer your questions with the information provided.I recommend scheduling a consultation with an orthodontist.  He or she will determine the necessary information to provided a treatment plan that addresses your concerns.  Whether or not extraction is the best option for you depends on how your teeth and jaws fit together.  If IPR is don't correctly, it is a great option along with arch width expansion to alleviate crowding without extractions.I hope that this helps and good luck!Best,Dr. Jenn
