<s>[INST] Hi, I had a wisdom tooth out on Mon and 4 days later my mouth is still swallen. How do i know if this is just a normal swelling after the surgery or whether it is infection.Also, I am worried about taking too many painkillers (ibuprofen) as I might be pregnant. I try to restrict it to 3 a day. Is this still too much? [/INST] Hello,  Welcome to HCM .  I have gone through your query, as you have have swelling after wisdom tooth extraction dont worry this swelling happens usually after wisdom tooth extraction for one week, if it persists for more then 15 days then consult your dentist.  Dont take Ibuprofen for if you are pregnant it harms you . Do warm saline gargle two - three times a day.If you have pain then take one tablet paracetamol to relief pain.Hope this will help you. </s>
