Health Tip: Your Teeth Are Tough

(HealthDay News) -- Your teeth are incredibly strong, and with the proper care and regular dental visits, you can keep them that way.

The American Dental Association offers these "tooth truths":

• Tooth enamel, which is 96 percent mineral, is the hardest substance in the body.
• Your teeth can exert an average of 200 pounds of pressure when you bite down.
• Teeth can last many hundreds of years, outlasting the person whose mouth they're in.
• Teeth are strong, but they don't heal on their own and require a dentist's attention when damaged.
