Dental Hygiene

Thanks to new technology, dental checkups are getting easier all the time. Some dentists even treat cavities with "smart fillings," which contain fluoride that releases over time to protect the tooth from further decay. 

With or without smart fillings, people need all the help they can get caring for their mouths. If you study dental hygiene, you'll learn how to care for teeth and gums and how to educate others about oral hygiene.
