Tooth enamel may be the hardest tissue our bodies produce, but it still wears away. Find out what wears down tooth enamel and how you can prevent it.
How Does pH Affect My Tooth Enamel? Ready for a mini science lesson? The “H” in pH stands for the chemical element hydrogen, and the “p” refers to the word "potential." So, pH is the “potential of hydrogen” andtranslates the values of the concentration of the hydrogen ions. The...
Take Care of Your Tooth Enamel That’s a hard, protective layer that helps your teeth deal with everything you put them through. When it’s gone, nerve endings that cause pain are exposed. If you have sensitive teeth, it’s possible some of your enamel has worn away. ...
The second grant will continue the work to understand the basic structural biology oftooth enamel, and the third grant is the exploratory proposal, with the idea to completely use chemistry strategies to synthesize a material similar to enamel in its properties. "Our idea is to use these short...
3doses throughout the day. Taking 30ml in one day is more than sufficient, and more than that could have other complications like drug interactions or tooth enamel erosion. Lastly, you may want to start with just 1 teaspoon (5ml) to see how well you tolerate it and build up fro...

prevent tooth decay and gum inflammation. Fluoride treatments are another preventative measure that can strengthen tooth enamel, making it more resistant to decay. Your dentist may recommend fluoride treatments, especially for those who are more prone to cavities or those with weakened enamel. Dental ...
In previous studies, we showed that the size of apatite nanocrystals in tooth enamel can influence its physical properties. This important discovery raised a new question; which factors are regulating the size of these nanocrystals? Trace elements can af
