I had a tooth extracted on Monday with bone graft. Today, Thursday i had some concerns about a strange taste so i returned to the dentist. after examining me he said that he needed to re-suture the area, this evening i just realized that the lower part of cheek seems to have been sutured into the extraction site. the dentist did say on Monday that i did not have a lot of tissue to work with, I don't feel comfortable going to my dentist with this question in case it is not normal, is this typical in cases where there is limited tissue?
