Carious tooth are sharp most of the time leading to trauma of tongue and that explains the cuts and burning sensation. The tooth would need a grinding to remove the sharp age. Root Canal If needed . Refereed pain from the tooth to ear region causing pain upon using an earphone. - Cap Sporidex 500 mg 1 Cap bd x 5 days - Tab Zerodol SP 1 tab bd x 5 days - Cap Pan D 1 Cap bd before meal x 5 days - Rexidine M Forte Gel , apply over the tongue. Rest, I can confirm upon seeing the image of chewing side of  upper Right jaw. Open your mouth wide and use a flash for clicking the image. Upload the image to me as soon as possible.

Hello, Get the tooth clinically checked , could be because of any sharp surface in the decayed tooth and could be because of the infection also ..
