[/INST] Thanks for your query, I have gone through your query. The redness in the gums associated with tooth can be because of the gum as well as tooth infection. The other possible cause can be herpetic gingivostomatitis, which is characterized by gum infection and ulcers. Nothing to be panic, consult an oral physician and get it evaluated. If it is a gum infection, get your teeth cleaned. If it is a tooth infection, then get the tooth treated with RCT. If it is a viral infection, you need to take topical anesthetic and analgesics like 2%lignocaine and choline salicylate gel (Anabel gel) apply 3-4 times daily before food. You can also take systemic analgesics like diclofenac 50 mg BID for 3 days for the pain. Do saline gargling. I hope my answer will help you, take care. </s>
