20101218 A Trip to the Dentist (2)

SC: Is there such a thing as brushing your teeth too much?

JC: The outer surface of a tooth is enamel. It is the hardest part of the human body, but the thickness of the enamel does not increase throughout your life. Rather, it decreases because it wears out.

SC: Why is flossing so important?

JC: Brushing can only remove the plaque from the smooth surfaces of your teeth. A lot of food actually gets trapped between teeth. Flossing is the most effective way to clean that food out. If you brush your teeth too hard day after day, you will wear down the enamel. Then your teeth will become more sensitive and might even develop cavities.

SC: How do you know when it's time to visit the dentist?

JC: In addition to your routine checkups, you should also go to the dentist if you have any problems with your teeth. If you feel any discomfort- a toothache or heat sensitivity- go to the dentist Even if you don't have pain, but just discoloration, bleeding gums or swelling, you should still go to the dentist. Dentists can cure dental diseases and make peple healthier.
