you should see an orthodontis. I think your teeth needs to be realigned or the cusps need to be reduced. For reallignmnet orthodontist will set the treatmnet for you but only after looking at the alignment of other dentition but if the problem gets solved from mere cusp reduction then it can be done by general dentist. Doing all this should reduced the pain not abruptly but though gradually...for more info visit the link...http://www.identalhub.com/articlecategory-braces-21.aspx
