The Basics of Teeth

We're joined by resident physicist and newly minted dentist Peter Vogel DDS to discuss the basics of teeth. What are the different layers of a tooth? What is fluoride and is it helpful or harmful? Is there a right way to brush your teeth? How does sugary food or soda affect the chemistry of your mouth? Are there certain toothbrushes or toothpastes that are better? Why shouldn't you brush your teeth right after eating? How does oral health affect diabetes and cardiovascular health? What happened to the tooth regeneration drug that was in the news a while back?
