my upper wisdom tooth injured my cheek. its like a tiny hole, and iv been putting peroxide on it and warm salt water gargling. i fear that it just keeps making contact with the tooth and further irritating it so really everything im doing to treat it is useless. i cant eat without pain, its horrible. i DONT want my wisdom teeth pulled, i just want this sore to go away and if it comes back i will seek dental help. so far i have been putting gauze around the tooth to keep it away from the sore, but this is really not easy. any other advice? iv also been using kanka for the pain
