The outermost tooth structure is called enamel. When decay starts to infiltrate a tooth this enamel begins to breakdown, a process known as demineralization. This is the start of a cavity forming. Light shown through healthy enamel is reflected differently that light shown through demineralized enamel.
Our Midwest Caries I.D. Detection Handpiece aids Dr. Evans in recognizing these very early cavities. This allows us to treat these cavities early with very shallow preparations into the enamel and sealing the teeth or smaller fillings thus conserving tooth structure. Both of which can be done with little or no local anesthetic.
