<s>[INST] My husband has had a toothache, went to the dentist a few weeks ago and dentist said he did not see anything. The last few days, he has complained about the same tooth and in the last few hours, his right cheek has gotten swollen.He is seeint the dentist tomorrow a.m. again, but i am worried about him this evening and can he wait until morning? [/INST] hello, if there is a swelling present than m sure there would be a infection.there is no need to worry. Just go to YOUR dentist ask fOR X-RAY of that area.if there is any deep cavity present related to that tooth than ask for root canal therapy. he ll be alright. </s>
