<s>[INST] My daughter age 16 had wisdom teeth pulled on June 16 and she recovered well. Four days ago we were on vacation and she was complaining of some pain (rated it a 3 on a 10 point scale). Tonight we are home and now she is complaining about a blister near the lower extraction site. When I looked in her mouth it looks like a blister, puffy, punish white near the extraction site on the gum, near her cheek. Should I be concerned? [/INST] Hello and welcome to ChatDoctori have read your query and understand your concern. As you mentioned it's more than one month since the wisdom tooth extracted. By this time the extraction should have healed.in some case of more traumatic wisdom tooth extraction slight pain is normal, and it can take more time to heal. Blister can be due to some other reason also. If I were your treating doctor I would advise you to use a chlorohexide mouth wash. For pain travel can be applied to the affected area. Usually it will subside within 4-5 days .if the problem persist or increases I would suggest you to visit your dentist. Hope this and your query. Take care. Regards </s>
