My husband had a tooth extraction a week ago on his upper left molar. He was smoking from the day of the extraction. He had eaten a breakfast burrito the next day and had food stuck in the hole. He's not a dentist, but had asked me to clean it with hydrogen peroxide. Basically since the day after the procedure, I've been taking q-tips, dipping them in hydrogen peroxide and cleaning the affected area every night. About 5 days after the procedure, he rinsed his mouth with mouthwash and the mouthwash came out of his nose. He still has considerable pain and when I use the q-tips there is blood and yellow pus-like stuff that is thick and semi-hard. I don't think I've been doing the right thing, but he claims it makes him feel better. I feel like I'm hindering the healing process. His dentist is out of town and I thought writing here might help. THANK YOU!
