Facts of Dentin

Dentin is semi-reparable. It has reparative capabilities because the odontoblasts that create dentin remain viable after the teeth erupt. When excessive wear, cavities or other irritants start to degrade the dentin, reparative secondary dentin is laid down.

As helpful as this is, the enamel that covers dentin is NOT reparable, so again, your biyearly trip to the dentist is mandatory, as is daily brushing and flossing.

When you get dental cavities, you get them in dentin. Generally, if you get an infection, you get that in the pulp of the tooth. But enamel can wear away by chewing ice or other irritants, thereby making dentin more susceptible to dental cavities and tooth loss.

The most important thing you can do to protect your teeth’s dentin is to brush twice daily and floss every single night — not just when it occurs to you! And don’t forget to see your dentist at least twice a year to keep dentin in tip-top shape.
