There was a lot of noise coming from the Best Western Heritage Inn Friday morning.

That commotion came from dozens of babies and toddlers, and they were all there for dental work. It's part of the Montana Dental Association's training session, a unique program that gives dentists and dental assistants real-life training and kids less than a year old.

Dental experts say that caring for a baby's teeth can be critical to a child's overall health. Every year, thousands of babies contract early childhood caries, also known as bottle rot.

Dentists say this is 100 percent preventable, through early detection and cleaning, which now is recommended before a baby turns one year old.

Jane Gillette, with the Montana Dental Association, says, "Which is much earlier than we used to think. We used to think about three or five, but by that time, the disease is very well established. And so what we're training people to do here today, is to see very young children, and teach them how to prevent cavities, so our children, Montana kids, can grow up happier and healthier."

The incentive for parents to bring their babies out on Friday was that all of the dental care was free.
