Did you know people with teeth live 10 years longer than those without teeth? The Mayo Clinic did a study and found out that this is all because of malnutrition. When you have no teeth, people are forced to eat softer, more starchier foods. This leads to diseases related to aging like obesity, diabetes, and heart disease.
People try to label dentistry to be only associated with teeth. This is far from the truth. Your mouth is the gateway to your body. Whatever is introduced or exists in the mouth will have an impact on your overall health of your body. Imagine if you let in every bad person that knocks on your home door into your house. Your house would be in an unhealthy state. The mouth and body are the same way.
Missing teeth are more valuable than you know. They not only allow you to have a beautiful smile, but they allow you to have the proper nutrition, which will allow you to live a healthier life. I could argue that teeth are the most important part of the body. They are things we use every day that can add or take away the years we get to live on this wonderful earth.
