I am suffering from toothache since 3-4 days. My friend suggest me to take clove oil directly to the teeth. But after taking this suddenly pain increased. I took zirac-sp pain killer. But pain is still there. When i am using water then suddenly pain gone. Please suggest me home remedies or pain killers as all dental clinic is so far away from my home.

I plan to get lingual braces however I'm concerned about the lisp that is may generate. Is it only a temporary thing or would it be there for the entire time? Also how much does it generally cost?

Since September i have been having repeated mouth ulcers( roughly 15 small ulcers from September to December 31st ). Small in size and they go away with little bit of cream and Rinifol/ Becosule tablet. Today while brushing I had a bit of gum bleeding very little (had to actually look it closely to see the bleeding.) I am afraid because this is similar to lukeimia. Please tell me if the Ulcers are something I need to worry about and if the gum bleeding is just coincidence.

M suffering from chronic mouth ulcers from 3 years.. Initially I thought it was due to constipation, then I decided to have a balanced diet & abstained from all fast foods & tried exercise, yoga n all. My constipation problem almost solved but I got 2-3 ulcers every month as earlier. I've taken B cosule capsule also many times. Because I  researched about mouth ulcers are due to lack of Vitamin B.. Please help me doctor.. I even I don't know which doctor I hv to consult

Is mucocele harmful? Size less than 1 cm . Seems not to be improving. It is in lower lip. Don't want to undergo surgery.
