I'm a nineteen year old in repair school right out of high school, and even though I'm going to be a tech, I'm a trumpet player first. I've been a bit out of practice, so today I practiced and practiced some more. It's was about 15 minutes here, fifteen minutes there. The whole time I practiced would probably be a few hours, but there were a plethora of breaks involved. I'm starting this thread because towards the end, and the main reason I stopped practicing today was that my bottom front teeth were starting to hurt. Now, I don't play with a lot of pressure, and actually had that problem when I was younger, so I try to play as relaxed as possible, with as little tension as possible, which includes pressure on my lips. I decided to get back to basics today so I was playing the First Studies of Arban's and stopped about halfway through number 10. I decided to get back to basics actually because I played through an étude I used to play and got the notes easily enough, but my endurance was lacking. My range lately has increased very well, but this endurance problem has been plaguing me, which really I'm blaming on not practicing enough(I really don't.) about once a week, and am practicing more lately because I'm on spring break.
Anyway, I was wondering if this hurting in my teeth is common, or I just over practiced today, any info would be appreciated. It hasn't happened before, and this is the first time it's happened, I'll let you guys know if it persists.
