Is the orthodontist to blame for tooth mobility and bone loss? (Photos)

Thanks for your question. Orthodontics of any kind (clear aligners or braces) can be associated with a higher risk of gum recession, but there aren't any studies demonstrating that it directly causes recession. Ortho also causes temporary mobility since the purpose of ortho is to literally move your teeth through the bone. However, if it's been a while since you finished Invisalign and you still have mobility (that is not caused by any other underlying issues) you can ask the dentist/orthodontist to check your bite to make sure it's even and functional. If you are contacting too heavily on your front teeth you may need a slight adjustment which consists of smoothing down of these areas. This heavy contact can cause slight mobility. Invisalign is only so accurate when it comes to your bite and an adjustment is regularly needed after treatment is completed. I hope this helps!
