Teeth Falling Out After Using Invisalign. Is That a Possibility?

Those reviews are not correct. As long as you you do not present with gum disease or bone loss, Invisilign treatment is great! You may however find that after the initial phase your teeth will feel loose.

I assure you that treatment with an Invisalign certified dentist is safe.  Your dentist will screen you for any warning signs (gum diseases, fractured teeth, cavities, etc) and make sure the treatment is safe.   I have personally overseen well over one-hundred invisalign cases and have had fantastic results.

As the old saying goes: "don't believe everything you read!

Assuming that you do not have horrible gum disease and bone lose before starting treatment (if you do you shouldn't be getting orthodontic treatment) then there is 0 risk that you will lose any teeth with Invisalign or braces...

Drs. Novak, Miyamoto-Shimali, and Waxler have given you wise counsel. ANY type of orthodontic treatment could result in loose or lost teeth if disease such as periodontal disease were present prior to orthodontics and not treated and managed to full health. No competent dentist or orthodontist would begin in such a circumstance.
