<s>[INST] hi, i have two little balls of skin in my mouth. One is one the left side by my back molar and the other is on the right. what can they be? They dont hurt. I dont know if this as anything to do with my mouth being dry for some reason. It never use to be like that but it is now. when i wake up my mouth is so dry and my breath stinks to high heaven [/INST] Thanks for your query, I have gone through your query. The balls of mucosa over the right and left side of your cheek could be an irrational fibrous secondary to the cheek biting by the teeth. Consult an oral physician and get it examined. Nothing to worry, it's a benign lesion, it won't harm you, If it is interfering with mastication or any function, then get it surgically removed under local anesthesia. The bad breath could be because of the deposits over the teeth causing gum infection. Or it can be because of the pus discharge secondary to gum or tooth infection or any respiratory tract infection like sinusitis or gastrointestinal disorders. Consult an oral physician and get yourself examined to rule out these conditions. If it is gum infection get the teeth cleaned once and maintain oral hygiene after that. You can use mouth wash. I hope my answer will help you, take care. </s>
