<s>[INST] Sir one of ma tooth broke and the sharp edge was constantly hitting my tongue for two days.then i got a root canal done.Now i have a small ulcer and pain in the tongue plus also one side of the throat i can see whitish structure and painful ,difficulty in swallowing..pls suggest me remedy or medications [/INST] Hello and welcome. Thanks for sharing your concern. The broken tooth/teeth should be ad Chat Doctor. It should be rounded with the help of aerator(dental instrument). After that if required a smooth and merging filling should be done on the affected teeth as per the requirement. After that please apply Denote as a local applicant at the affected area 3 to 4 times daily. Simultaneously take capsules B complex for around 15 days, and it should heal. Hope it helps. Thanks. Take care. </s>
