Preventing me from cancer

I have irregular teeth. Which seems like a minute issue. Sadly not for me. My teeth press hard against the gums causing inflammation of gums. It creates environment for yeast infection thereby also causing ulcers. Ulcers which I have for last 5 years and they never go away. My doctor is saying it will eventually turn into tumor and later into cancer if not corrected now. I want to save myself from cancer. The only way is to correct the teeth so they don't cause inflammation of the gums and stop this chain reaction. The teeth correction will cost around 3,00,000 Inr ($5000). Everyone is saving people with cancer. Please save me before I have cancer.
