Most certainly, if the breaker is 20Amp, you should be using 12GA wire. No questions asked.

Also (I know, probably a really dumb question), but make sure there are no aluminum wires in your walls. My dryer plug burnt up recently, and when i opened the box (thank god it was metal), it was charred up, and the wires were aluminum, while the plug was copper.

If you do have aluminum wires, either replace them, or use the anti-oxidizing paste on all the connections.
