<s>[INST] Hi, I have been having problems with the left side of my mouth for 3 days now. One night the lower left side of my mouth started throbbing and I could not touch the area, my gums and teeth were throbbing. I have had anti-biotics and penicillin the pain eased off but it has now come back. I have noticed that I have got a small white spot under one of my teeth at the bottom of my gum what could this be? [/INST] Hi, Thanks for asking the query, Tooth pain along with swelling in the gums indicates infection in the tooth that had spread to the periapical tissue leading to abscess formation. Chat Doctor. Go for symptomatic treatment of complete mouth scaling and polishing. Start with the course of antibiotics and analgesics. Maintain a good oral hygiene take antiseptic mouthwash rinses. Hope this helps out. Regards... </s>
