A dental hygienist is an oral health professional who has obtained training and completed a degree from a recognised University. A dental hygienist works closely with the dentist to look after your gums and helps you maintain oral hygiene. They examine your gums and other soft tissues in your mouth. Once the examination is completed, a dental hygienist will address all areas of concern by removing plaque or other deposits around your teeth or under your gums. Any stains on the surface of your teeth will be cleaned. Finally, a dental hygienist will also show you the best method to floss your teeth and use your toothbrush.
