started to hurt to open it...? so a few months after it started poping it would feel tight and hurt a little and it hurt to open it all the way...Once when i opened it too wide it kinda felt like it was stuck for a second.then it went away fora few days and then it started again with the popping..now it doesn't pop but it hurts and feels tight and i can't open my mouth all the way cause it hurts... it'll feel better for a while if i pop it sometimes...do i need to tell a dentist?? I sometimes do clench my teeth so do i need a mouth guard thing?? thanks!
