Fairly regularly, certainly frequently, my gums recede making my teeth sensitive and letting them move more than usual.
I am a trumpet player.
This is not good. Trumpet players should not have dodgy gums because it scares them (me) and makes them think that their teeth might fall out.
Even though they (I) have been to the dentist who has said that it's caused by over-brushing or not flossing properly but that the teeth are firmly fixed in the bone so not to worry.
