First Step for Dental Innovation “No Cavity”
I had a cavity and the American dentist gave me only one option and I didn’t like it. I wanted better options. So I started innovating to satisfy my desire. Before you think that I started inventing something let me clarify innovation. Innovation is satisfying a demand. If you can find something that already exists and use it to satisfy the demand you innovated. So I began searching. The innovation I wanted was No cavity.
Since I wasn’t an expert on dentistry I did a little research to understand at a high level how dental caries (cavities) function.
Acid from bacteria eat left over food and cause decay in teeth. Your mouth has a natural defense for the acid. Your saliva is alkaline, it neutralizes acid. Unfortunately bacteria can stick to teeth blocking saliva from neutralizing the acid.
Saliva has another positive feature. If the infection that causes decay is caught early enough teeth re-mineralize all on their own using material in your saliva.
If too much damage is done there is a hole that could collect food and bacteria. Once that hole gets through the hard enamel, a cavity can quickly grow in the softer dentin. It’s still possible for a tooth to heal at this point but often some type of repair is needed. But most important is stopping the infection and decay.
Many cavities form in areas of teeth that catch food and are hard to clean. The tendency for bacteria to stick to teeth makes this even worse.
Functional Diagram
Taking all the information I gathered I created a Functional Diagram. The red boxes describe how cavities work. The green boxes describe the process of filling a cavity. And the yellow boxes show the natural process of saliva re-minerizing teeth.
The Functional Diagram give you a high level starting point to start looking for innovation alternatives.
