Dentine is very white. It's your tooth enamel that is translucent. This means my translucent teeth were actually trying to show me that my dentine was screaming for nutrients. Dentine uniquely requires vitamin K to produce osteocalcin, which is a protein that organizes calcium and phosphorus deposits into bone for mineralization. So....if you have enough minerals, fat-soluble vitamins and work to maintain an internal pH that is alkaline you can rebuild your teeth.
