Thanks for the feedback everyone.

I was considering braces and saw the oral surgeon right before I was diagnosed with tongue cancer.

Right before cancer, the dentist suggested them not only because of aesethics but because it would be easier to clean and floss my teeth. I was also biting the inside of my tongue all the time because of misalignment.

So now after radiation, I only think about it because I would be able to do a more thorough job flossing which is important in my overall health of my delicate tissues inside my mouth. The straighter teeth is just a side bonus in my case.

Anyway, I don't know yet what me and the dentists/doctors will decide. I still have more research to do. I may wait another couple years because my tongue is still very sensitive and I do have dry mouth.

Thanks.
