Since last 3 weeks, i have been feeling that i have biting sone stones in my mouth. I visited my dentist, she said there is no problem with my gums, or veneers(did 12 years back), although there are two composite fillers done 10 years ago, which maybe shedding. Or my teeths are getting brittle that could be reason. She is also not confident what exactly is happening. I did my gum fillers but the problem still persist. I didn't find any result on internet. Does anyone has come across such issue?
