Genetically Defective Proteins May Explain Some Tooth Decay


According to a recent study conducted at the University of Zurich, there are certain mutated genes that lead Cavities-midrb7tjsl2awrwwu79gn6yuensl5witp860dcue98to defects in the tooth enamel, and, to tooth decay. Enamel is created by development of specific enamel proteins. If there is a genetic predisposition to form defective enamel, the teeth become ready hosts for bacteria to create holes and decay in the teeth. Documents about the study explain that “there is a direct link between mutations in the genetic blueprints for these proteins and the development of tooth enamel defects.”

In other words, tooth decay is not just a result of bacteria in the mouth and on the teeth. When the genetic defect causes enamel to be weak, soft, or otherwise defective, the tooth cannot defend itself against the bacteria.


·Â Â Â Â Â Â The genetic predisposition to formation of defective tooth enamel means that in many cases brushing and flossing regularly might simply not have a chance to protect the tooth from bacteria and decay. In other words, it might not be entirely your fault.

·Â Â Â Â Â Â This understanding of how tooth enamel forms should lead to new oral care products that can slow the effect and progress of to

oth decay in people with this genetic tooth enamel defect.

·Â Â Â Â Â Â This knowledge might explain the tooth decay your dentist or hygienist discovers in spite of careful and regular brushing and flossing.

If you know you are caring for your teeth correctly, and you still develop significant tooth decay, you might want to ask your dentist if this genetic mutation could be the culprit. She will know about new products becoming available that can help you deal with the problem. She might also have other ideas that will help you manage oral care more effectively.
