Welcome to our second blog. I’m going to start a 2 part series today on what is a cavity and how do we fix it. I will discuss fillings today and lab made restorations like crown in the next blog. According to the National Institute of Heath, 92% of people will have had a cavity on a permanent tooth by the age of 20. Today we are going to focus more on what is cavity and how we can restore the tooth to full function.
