Tooth hitting canker sore in the back of my mouth, can't close my jaw/mouth all !

Tooth hitting canker sore in the back of my mouth, can't close my jaw/mouth all the way because of it?

My wisdom tooth is hitting a sore I have in the back of my mouth on the left side. I've had the sore since last tuesday when I had a tooth extracted. My dentist told me over the phone that I probably just bit my cheek and that's where the sore came from. And that it will go away eventually. Well how long is eventually, I haven't been able to close my mouth all the way for almost a week now, I can't touch any of my teeth together, therefore still have to eat only foods that can be swallowed without chewing. Any advice?

**My tooth isn't really rubbing against it, the way the sore is, when I go to shut my mouth, my tooth sits on top of the sore making it so I cannot shut my mouth, I've tried pain relievers, and they help with the pain, but not with me being able to close my mouth because my tooth still sits on top of the sore.

your dentist is correct. I have seen this with my job. It will take about another week to 10 days to go away. My suggestion is to go buy the chloraseptic sore throat spray. This spray contains an ingrediant called Phenol that numbs areas of the mouth simular to novicaine. It works better then you could imagine. Go buy this spray and spray it directly on the sore and you will be completely pain free. You will be so relieved to be able to close your mouth without being in pain all the time. Trust me and go get the spray, it works awsome. Let me know how it turns out, I promise you'll be thanking me later.

p.s. It comes in a red cherry flavor, the exact spelling of the product it Chloraseptic then underneath it says phenol/oral anesthetic.
