Crowded teeth: Is it necessary to extract before Invisalign? (photo)

Reluctant to Remove Teeth

Hey NE2244, Removing teeth, especially four teeth should only be done if it's absolutely necessary.  In my orthodontic practice, we generally remove 4 teeth for severe crowding (which you do not have) or changes in profile (which I cannot see).  Just based on the photos, it does not look like extracting teeth is absolutely necessary.   I find that you can easily add 1 year of treatment time by extracting 4 teeth especially in Invisalign.  It is very difficult to do removal of 4 teeth with Invisalign and I hope you have an experienced Invisalign doctor for that situation.  Good luck!

Looking at photos you have mild to moderate crowding 
the arches can be expanded to correct the crowding so I do not recommend removing 4 teeth

Are extractions necessary?

Thanks for taking photos.  You basically have two options when it comes to reducing the crowding of your teeth.  Here they are:

Option #1:  Extract a couple of teeth per arch.  Then use Invisalign to align your teeth in a non-crowded manner.

Option #2:  IPR (inter-proximal reduction).  This is when the dentist makes each tooth skinnier by creating small spaces between them.  These spaces are later closed as your crowded teeth spread out into better alignment.  

Ultimately, your dentist would make the decision that he/she feels is best, so if you are wavering, it is nothing wrong with getting a second opinion by a cosmetic dentist.  I actually encourage my patients to get 2nd opinions whenever they seem undecided on care. Good luck to you and I hope this helps.
