Here's an update (kind of). The area on the end of the lingual frenulum under my teeth towards the gum looks like a very small spot and is translucent. There doesn't appear to be white (from what I can tell). I am continuing to have dental work done this week. Both the hygienist and dentist saw the area closely today, and I'm scheduled to return tomorrow. The dentist did not say anything to me (yet anyway). I would think he would say something if there were an issue ??? I'm not being forthright because I'm scared.
