When you visit our office for a routine hygiene examination and cleaning, we check your teeth for specific problems that can affect your oral health. Of course, we thoroughly clean your teeth, but we are looking to see if there is a buildup of plaque and bacteria that would indicate your teeth aren’t getting as clean as they should be. We also look for signs of decay, also known as cavities. Many people are aware of the term “cavity”, but do you really understand what it means and how it is caused?
