5. What does the dentist or hygienist look for during a checkup?

7. What can you do to help prevent cavities?
Brushing after every meal, and flossing daily are important in helping to prevent cavities, because they remove plaque. If plaque remains on your teeth, the bacteria that live there produce acids which create the holes, or cavities, in your teeth.

9. When the dentist fills a cavity, what does he do first?
First, the dentist must drill the tooth to get rid of all the decay before he can put a filling in. Usually, he will give you some anesthetic (like a shot [or injection] of Novocain) to numb the area so you don’t feel anything.
10. What are fillings made of?
Fillings used to be made of amalgam, but these are not used so much anymore because they have trace amounts of mercury, and they don’t look very nice in the teeth. He can put in a gold filling, but gold is too expensive for most people. So it is most common to use bonding, where the color of the filling is close to the natural color of the tooth.
11. What happens if your tooth has a cavity that’s too big?

Paragraph: A Visit to the Dentist
When you go to the dentist, he will have you sit in the dentist’s chair for your examination. He will put something like a bib around your neck, and tell you to open wide while he pokes around in your mouth, visually inspecting your teeth and gums for any problems. Wearing rubber gloves, the dentist will use his dental pick to clean your teeth, removing tartar from in between the teeth, under the gum line, and other hard-to-reach places. After that, he will polish your teeth with some special paste and a type of hand-held buffer. If he takes x-rays of your teeth, he will put a lead apron over your torso to prevent unnecessary exposure to radiation. Then he will insert the x-ray cards in your mouth and turn on the machine to take an x-ray.
If you need to have a cavity filled, the dentist will first give you some anesthetic – usually a shot of Novocain. This is to make your mouth numb in the area where he has to drill, so it won’t hurt. The dentist must drill to remove the decayed portion of the tooth before he fills it. He may use mercury (silver) amalgam, which is relatively inexpensive, or he may use bonding to fill the tooth with natural-colored resin fillings. Some people may wish to use gold for a filling instead, but of course this is more costly.
After he has finished working on your teeth, the dentist may tell you to rinse and spit. Part of the reason for this is to eliminate any debris, grit, or saliva that might remain in your mouth after the procedure, but the other reason is to get rid of any unpleasant taste.
As nice a fellow as your dentist might be, you probably don’t want to visit him any more than you have to. So you want to be sure that you floss at least once a day, and brush after every meal – these are small and easy but important steps that you can take to make sure that your teeth will last a lifetime, and to keep yourself in good dental health.
