I grind my teeth a lot. Well last week a part of my back tooth cracked off. Went to the dentist, but in the mean time before I got the tooth fixed - my tongue was rubbing against the broken tooth. And now I have this sore on the left side of my tongue. There was a piece of loose skin on it so I pulled it off. It has been hurting ever since. I hope you can help. I am really in pain. I have been puttin  salt &   peroxide on it every day.
Hello and welcome. Please stop using salt and peroxide in this case. You can apply Colonel antiseptic cream which is a painkiller too. You can apply it three to four times daily. You can also take analgesics for two days(if required). Avoid strong and irritating spices, condiments and soft Chat Doctor. The lesion on tongue will heal by self-healing mechanism. Need not worry. Also note that the jagged teeth should be ground and corrected soon so that further damage to tissues can be avoided. Hope it helps. Any further query please let me know. Thanks. Take care.
