Are my teeth too bad for Invisalign? (Photos)

Great Pics!!!The spaces between your upper front teeth are likely due to the bite- too much bite pressure on the front teeth and not enough on the back teeth.The Inman aligner is not your best choice as you really need to treat both the uppers and lowers.Invisalign will give the dentist control...

The smooth surfaces of the appliance should not be an issue, ie no sharp edges.Oral sex can be dangerous if you have TMJ issues, especially locking closed.

Yes , yr teeth are not perfectly aligned. refinement is must in yr case. additional few aligners will resolve your issue. IPR might be needed.

Hi, Ying.  It does look like external root resorption on your tooth #12. We do not know what the cause of external root resorption is but it its associated with trauma to a tooth. There really is nothing that can be done for the tooth unfortunately. It may be years before you lose the tooth...

Your teeth don't follow the trays, thus they don't fit. You may have to go back a few trays and maybe needs more IPR (interproximal reductions). Hope you saved you last few trays, as it is crutial to go back and see where the problem started.  

Hi, girl83. Personally, I never like to remove teeth to correct crowding and I don't advise you doing it with this tooth. You can straighten the teeth and then correct the one discolored tooth with a porcelain veneer. Hope this helps.
