<s>[INST] I had a tooth worked on yesterday and as it was sensitive the dentist numbed the area with an injection. Today the gum is a little swollen and the two injection sites around the tooth are white. My dentist doesn't open until Monday, is this a normal side effect? [/INST] Welcome to HCM forum,Thanks for posting your query,I would like you to know that the white spots will resolve soon, but for the swollen gum if it is painful then i will advise you to see your dentist soon but if it symptomless then perfoem warm saline rinses 5-6 times/day and it will subside the swelling.I hope i answered your query.I wish you good health.Take care. </s>
