20 Amp Dedicated line: 10 gauge vs 12 gauge wire


Is there any issue running a 10 gauge wire in a 20 amp dedicated line vs. a 12 gauge wire.
It seems that a 10 gauge wire would heat up less.
Thoughts/comments?
Thanks.

Well it's been a few years, but I know my 20A lines are 10 guage wire. I think it's code here in Michigan?
