A month back my tooth got chipped and i recently contacted a dentist nearby got examined as im having problem eating cold foods like icecream. They examined by keeing some cold spay sprayed on cotton plcing on chipped tooth.They took an xray and at first prescribed pulpotomy and again before starting pulpotomy they asked for retake another xray and now they are prescribing rootcanal .but at that instant i have short of time so got filled with some composite now able to eat cold things like ice water but a little sensitivity for icecream. When tapping teeth with finger at the bottom with some impact a little sensation is there on fractured tooth now. Is root canal compulsory required?

Sir my front teeths has a gap i want to feel it what should i choose and what would be the cost of braces?

Stolin can only be used over the areas needed or even on the areas other than the infected one

Had a sore jaw for three days on left side. I can notopen mouth wide or it is painful. Getting worse as the days go on. What should i do? Left ear sore.

I've been through root canal treatment for 4teeth with respective tooth numbers 15,23,25,26.There was no pain during filling of root canal and was restored with crowns.Later after 2weeks severe pain started every alternate day and sensitivity while drinking hot tea.I approached the hospital and they have done Re-Rct for the respective teeth with intracanal dressings for 2weeks and sealing it with confirmation of noo tooth pain.But the problem again started after 10days,I'm feeling pain on bite.

Actually their is sever pain in my tooth and also I consult to dentist but I don't won't to do root canal is tooth extraction is possible
