Tooth and Mouth Problems

I have recurrent mouth ulcer every month. So i don't know what to do. Am i having any nutrition problem? or any other problem.

My mother is having toothache and severe swelling on face. Doctor has suggested for either root canal or implantation. Which is better. What would be tHe side effects. Will root canal can lead to infection in other tooths

I have this weird feeling in my mouth/throat almost constantly, and it makes me feel like I'm going to throw up. My mouth is extremely dry a lot of the time no matter how much water I drink, and I'm always feeling like I might gag. Tums/pepto bismol/ and mint candies are my only relief and sometimes that doesn't even help. It is worse in the evenings/late at night until I can finally fall asleep.

A whity layer is always peeling from the mouth and also on the tongue .Which has no pain but is not comfortable .Why this happens?

If i have a tooth abscess and it pops and 8 accidentally swallowed some of the stuff what will happen?

Need opinion whether surgery can be done or not as palate cancer is diagnosed for my aunts and doctor said surgery cannot be done

One tonsil is slightly larger than the other, slight soreness, it kind of looks like a lump. I have allergies and it only started being a little tender this morning. I'm just wondering if this look like a tumor or cancerous type thing. Image Below http://oi63.tinypic.com/2upzi8k.jpg
