I too had a big scare last week. I went for what I thought might be my final adjustment on my dentures. Instead my dentist called in the other dentist and they both looked at my frenum and told me not to wear my dentures any more until I have my ENT look at my mouth. They didn't use the word biopsy, but they more or less told me to go back to my "cancer doctor" - this has me just sick. I will be calling tomorrow for an appt. Man, I hope like tiamaria that a nacho just cut my frenum. I was just getting where I could eat those.
