Hello,

I have a friend who has been using invisalign for almost a year now.
Every couple of weeks she goes to her orthodontist to get the newest
retainer. After getting her latest retainer she started experiencing
some more then usual pain in her teeth. She made an appointment to see
her orthodontist two days later by which time the pain had receeded.
It turned out that one of her teeth had died and now she needs a root
canal.

Is it possible that the pressure caused by the invisalign braces
caused the tooth to die?
If so, is this a well known risk? Do people know of similar stories.

Any answers to the above questions would be greatly appreciated. We
are trying to work out what happened, and what are the risks in
continuing the invisalign treatment.

Tahnk you in advance,

Aaron Zelechow
