Tooth and Mouth Problems

I am having a white patch in mouth near last tooth on cheek I have seen a video on YouTube that this is a sign of cancer can you please advice me what to do

Have been getting white soft patches on the inside lower lip.these are soft and often go out when pulled by teeth. They happen more when I smoke and when I don't they go away. My mom also used to get similar soft tissue patches and stopped over time. They have been happening for 3 years now. I had consulted my dentist she said if it goes away on scrubbing it's harmless. What can be the reason for this.

I have severe toothache daily and experience the same from last 1 month but severe pain from past few days. the pain is usually experienced only midnights and am not having tootache in day time.

Tongue rashes. Pls check the tongue photo and suggest us whom to consult fighter dentist or general physician?

I'm able to see a small black hole on right side of my tooth. from past few months.What could be the reason??

My wisdom tooth was hurting from yesterday morning....I went to a dentist...he gave me some medicine and a gel...when I take the medicine the pain subsides...but after 4-5 hrs...it comes back again...also this has resulted in fever as well...and shivering...the doctor said if the pain remains even after 3 days, then they might have to remove it....
