On tuesday, having an upper mouth dental impression for a whitening tray. need replacement now. it's difficult for the florida dentist to remove the impression mold from my teeth. it actually feels it will loosen crowns, implants, recessed teeth?

Speak to the dentist about this concern prior to getting the dental impression done so that this can be taken into account. If there is a risk of loosening your dental work, then perhaps another plan will be needed. If this risk is low, you will be able to make a decision about proceeding. Good luck!

If so concerned have dentist use a light body impression material. It doesn't harden as strong as other materials. Also there preformed trays for whitening. Either way your dentist knows the condition of your oral health and will choose the best treatment plan.
