[|Human|] 6 of my teeth have broken off in the back one is a capped tooth the others are originals in the last two months. I also notice black on the gum line. Also in the last two months. My whole jaw is painful I do grind my teeth in my sleep. My tongue IS effected that rub against the broken teeth. Please advise
[|AI|]  Thanks for your query. I have gone through your query. The breakage of teeth can be secondary to grinding of your teeth. The other possible cause can be secondary to decayed teeth. The black staining over the gums can be secondary to deposits, or it can be a physiologic pigmentation. Nothing to be panic, consult an oral physician and get it evaluated. If the teeth are decayed, then it has to be restored. If there are any deposits over the teeth then, you need to get your teeth cleaned. I hope I have answered your query. Take care.
