Would Wearing a Dental Guard Prevent Me from Chewing My Cheek?

I just went to the dentist and he told me that if I don't stop chewing my cheek I might need surgery to repair the extensive tissue damage I've caused. I don't realize I'm doing it and was wondering if wearing a dental guard like what people wear to stop grinding their teeth would help?

Suggestion:

Yes, I used to bite my cheek and my mom told me about using a mouth guard, and it helped me to stop, i still do it sometimes, but it wouldnt hurt to try!
