What is this???

I noticed a red spot inside my mouth tonight. I think its a canker forming but want a second opinion and I don't have dental insurance.

I've had cankers before. I've been drinking two glasses of OJ to get extra Vitamin C the last few days and had some tomatoes too which I read causes cankers. Usually though my cankers look white. I've never seen this red spot before. Maybe this is just the beginning of one?!?

There's no other spots or bumps in my mouth.

Thanks you.

Looks like trauma.  It is on your occlusal plane (where you bite; where your teeth come together) and the most common place to see that.  It will go away in less than a week.  If it doesn't go away in a week to 10 days, then go see your dentist.  It is nothing serious because that would be a rare place to find anything serious.
