What Does the Dentist Do? The dentist is a doctor who is specially trained to care for teeth. When you visit your dentist for a checkup, he or she will look at your teeth and gums to check for any problems. The dentist also wants to make sure your teeth are developing properly as you grow. It's important to visit your dentist every 6 months to make sure you're taking good care of your teeth and that your teeth and gums are healthy. What Happens at the Dentist's Office? After your name is called in the waiting room, you'll go into an exam room and sit down in a big comfortable chair that is like a huge recliner. The chair will have a place to rest your head and lots of room for you to stretch out your legs. Next to the chair may be a little sink with a cup that you can use to rinse out your mouth as your teeth are being cleaned. During the exam, your teeth will be cleaned, flossed, and checked for cavities. Here's what will happen: Cleaning and Flossing One of the first people you'll meet at the dentist's office is the dental hygienist (say: hi-gee-nist). A dental hygienist is a person who knows all about keeping teeth and gums clean and healthy. The dental hygienist will look inside your mouth to make sure your teeth are growing properly and your gums are healthy. A bright, overhead light will shine down into your mouth like a giant flashlight so the dental hygienist can get a good look at your teeth and gums. The dental hygienist will clean and polish your teeth, using tiny dental tools like a tooth scraper, mirror, and special toothbrush. The tooth scraper removes plaque (say: plak) from your teeth. Plaque is a thin, sticky layer of bacteria (say: bak-teer-ee-uh) that grows on your teeth after you eat. Plaque that isn't removed from your teeth can cause decay, or cavities. Next comes brushing and flossing. The dental hygienist will brush your teeth with a special toothbrush and toothpaste. The toothbrush has a small round tip that moves around and around to clean your teeth. The toothpaste will taste a little like your own toothpaste at home, but it will feel a little grittier - almost like sand. Then the dental hygienist will floss your teeth and show you the proper way to brush and floss your teeth at home. Checking for Cavities During your visit, the dental hygienist will take X-rays, or pictures, of your teeth. X-rays are like super-human vision. They show any cavities hiding
