5 Reasons Your Smile Is Stronger Than You Think
The right smile can leave you laughing, fill you with joy or make you melt with emotion. But, ultimately, the best smile is one that is healthy and strong. Here are some of the ?tooth truths? about how tough your teeth really are ? and how to keep them that way.
1. Tooth enamel is the hardest substance in the body.
The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body ? making it durable and damage-resistant.
2. Your bite is powerful!
Did you know your teeth can exert an average of 200 pounds of pressure when you bite down? That?s probably what tempts us to use our teeth as tools from time to time ? but as your dentist will remind you, that?s one of the worst habits when it comes to preserving healthy teeth.
3. Teeth can last for hundreds of years.
Thanks to the durability of tooth enamel, our teeth actually outlast us. In fact, some of the most fascinating things we know about human history come from the study of our forebears? dental remains. For example, we know that the first travelers to leave Africa for China set out as many as 80,000 years ago ? and that early humans used a simple form of aspirin for pain relief ? thanks to teeth!
4. Strong as they are, teeth can?t heal on their own.
All other tissues in our bodies have the power to repair themselves, but our teeth can?t. When damaged, they must be repaired by a skilled dentist using caps, crowns, fillings or veneers. When our teeth fall out, the only options are partial or full dentures or dental implants. (Just one more reason to take great care of your teeth every day!)
5. Healthy teeth have the power to resist decay, but they need our help.
Did you know there are more than 300 kinds of bacteria that can attack your teeth? The good news is that with healthy dental hygiene habits and regular checkups, you can protect your teeth from bacteria and other substances that can weaken teeth and cause decay.
