One of the most common questions of mushers and others on the trail is how do you stay clean? The short answer is -- personal hygiene goes away.

Sure it's a challenge. No one's staying at the Ritz. However, rookie musher Brett Bruggeman is still doing what he can.

"I have these mini toothbrushes that are disposable and... that's what I use on the trail," said Bruggeman.

Dr. Bruggeman is an endodontist. He does root canals so it would be hard to tell his patients to brush twice a day and after meals.

On the trail, his "handy toothbrushes" are disposable mini toothbrushes. 

"Look at that, you do have a toothpick, and one tooth at a time. That's what I use, there's toothpaste in the middle of 'em. Makes it pretty simple," he said. 

And if you're wondering -- no, he does not do the same for his team.

"Not when you have 44 dogs," he said.

Right now, there is no schedule, no diet, and we mean no diet. At checkpoints, mushers leave behind all sorts of half-eaten sugary treats.

Even on the Iditarod trail, Dr. Bruggeman's menu is tooth friendly.

"Frozen grapes. Those are pretty good," he said.

Out here, it may not be an apple a day but brushing still goes a long way.
