A cavity may not seem like a big deal until it becomes painful. But beyond the discomfort, an untreated cavity can lead to bad breath or an infection and could result in an extraction. Instead of putting off having that cavity fixed, call University Park Family Dentistry at 574-272-4441. Our dentist, Dr. Jeffery Turner, will use a composite dental filling in South Bend, Indiana, to restore the health and appearance of your tooth.
