Your teeth serve many important purposes. One of their most important jobs is biting and chewing, allowing you to eat properly and stay healthy. They aid in a speech by controlling airflow. Your teeth are also one of the first things that people notice about you. When your teeth are discolored, misshapen, damaged, or missing, your ability to perform the simple tasks of eating or speaking becomes more difficult. These defects also affect your smile and can give people the impression that you are older than you really are, or they may be all the other person can focus on.
