How often should I be coming here? This is a question we hear frequently in the dentist office. Unfortunately insurance companies, not the dentist, have decided that the average patient should receive two cleanings and exams a year. Not everyone falls into this middle range. (It should be noted that most insurance companies will allow an additional cleaning and exam during a year the patient is pregnant). The Wall Street Journal article below goes into more detail. Not sure where you fall on the spectrum? Visit your dentist to discuss this matter.
