Your molars and premolars are specifically designed to help you chew and grind your food. The ridges or cusps that they use in the process, however, often trap food particles and plaque that can lead to cavities and other problems for your smile. At Ipswich River Dental, we provide dental sealants in Ipswich, Massachusetts, to keep your back teeth healthy, and you can call 978-356-4733 to plan your visit with our dentist, Dr. Matthew W. Knight.
