1. Use Specialized Toothpastes
First, some bad news. There is currently no way to regrow eroded enamel. Enamel is the substance that coats the outside of your teeth and it’s the hardest substance in the human body. But it can also be worn away over time. Brushing and consuming acidic foods are the two most common causes of enamel erosion. Once it’s gone, it’s gone.
However, you can remineralize the enamel you have left and thereby shore up your teeth’s protective coating.
Several brands of toothpaste are designed to protect against acid erosion and to strengthen existing enamel. They do it by pushing calcium and phosphates into your teeth, with an assist from good old fluoride. Dietary acid pulls these strengthening elements out, but fluoride is able to reclaim them from our saliva and draw them back into teeth.
