Is your son or daughter beginning to have his or her permanent teeth erupt in the front of their mouth? This exciting time means lots of changes in your child’s bite as well as their appearance. It’s also a time that we frequently get asked a lot of questions – especially when it comes to what those adult teeth look like. One of the most common questions that dentists get is, “why are my child’s teeth yellow?”
There’s a Great Reason
Baby teeth (primary teeth) are very white in color. It’s just the way they are made. Dentin, which is yellow in color, is the layer of tooth underneath the enamel. Primary teeth have a higher enamel to dentin ratio. As a result, the baby teeth look very, very white.
When the permanent teeth begin to erupt, there is a stark contrast in their appearance compared to the baby teeth. Permanent teeth have a higher quantity of dentin under the outer layer of enamel. Naturally, this makes the teeth look darker. If the permanent tooth is immediately adjacent to a primary tooth, the coloration is extremely noticeable.
