I have an essix retainer and i have had some rough spots on it for over 2 months. is it possible that these rough spots have damaged my teeth?

Doubtful but...: It is hard to say if some rough spots on a retainer can cause any damage to your teeth. If you are not thoroughly cleaning and flossing your teeth before placing the retainer, then yes, damage can occur. I am surprised that you did not get back to the provider whom made the retainer and point out the problems. I would do so asap.

Not likely: Essix retainers are intended to be used for a limited period of time. Sometimes, especially with prolonged use, they become rough and may cause irritation to the gingival tissue if they are not properly trimmed. Consult with your dentist to see if they can make it more comfortable.

No: Tooth enamel is considerably denser than the plastic used to make an Essex retainer. Rough or ill-fitting retainer can, however, irritate gum tissues. If you think teeth or gums are damaged see you4 General Dentist for evaluation. Also see the General Dentist or Orthodontic Specialist who made the retainer for an adjustment to remove any rough spots.
