At Joel D. Singer, DMD, we are passionate about helping our patients achieve optimal oral health. One way we encourage this is to have patients visit our office for routine hygiene examinations. During these appointments, we not only thoroughly clean their teeth, but we also look for signs of a problem with their oral health. One common issue that many of our patients experience is dental decay, also commonly referred to as a cavity. You have likely heard of cavities. Maybe you have even had one or two. But do you know how they form and what can happen if treatment is not received?
