'Glee' First Look: John Stamos as Dr. Carl Howell

September 7, 2010 (2:54 am) GMT
The hot dentist is giving Will Schuester a check as well as ripping his heart in the competition to win Emma.

joining "" is a piece of old news but the first look of him as hunky dentist is new. TV Guide shared a promotional photo of Dr. Carl Howell in his jersey, examining Will Schuester's teeth. These two characters will collide in Emma's world.

"Just when Will thinks he'll win Emma because he can sing and dance, we find out Carl used to be in an '80s boy band," Stamos said. "I discover Will's chewing his teeth, so the other day I had, like, four fingers in 's mouth."

Apparently, Dr. Howell has been going out with Emma even before viewers know about him. "They're already together, yeah. I think they've definitely been together for a little bit, and he's kind of helping her with some of her issues," said to Movieline, referring to her OCD and germaphobic issues.

Dr. Howell's significance in the second season is also as a bridge to dream sequence. He would be administering anesthesia to Brittany, Santana, Rachel and Artie who will then experience performing with the pop star herself. "Poor Brittany has cavities in every tooth," Stamos said.

Stamos' episode is to air on September 28. He will re-appear in the Halloween-themed episode where he would be singing.
