Power
You have the power to change someone's life. Many people are inflicted with crooked, missing, or discolored teeth that cause them a great deal of emotional pain. Even famous people (such as Chris Rock) suffer from self-esteem issues because of their teeth.
Poor self-esteem isn't the only problem. Poor dental hygiene can contribute to heart problems, respiratory disease, severe gum disease, pneumonia, sepsis, and mediastintis. Even if you don't know what all of those things are, you know they don't sound good.
It doesn't take an invasive surgery like dental implants to change someone's life. A simple teeth cleaning can remove bacterial plaque, which causes cavities, periodontal disease, and gingivitis.
Dental plaque is a colonization bacterium that forms on the surface of the tooth. There are over 25,000 different species of bacteria in your mouth (hope you're not reading this while eating dinner). Bacteria like to eat all the stuff you like to eat, like donuts, Ho Hos, soda, fruit, and candy. When bacteria digest these foods, they turn them into acids, which dissolve the enamel on the tooth. Voila. A cavity is born.
You have the power to clean teeth, fix bad teeth, and give someone tooth implants. Your patient will not only become more confident, but they may also live longer.
