Cancellation Policy At Summit Dental Group, we make every effort to be on time for our patients, and ask that you extend the same courtesy to us. If you cannot keep an appointment, please give us at least 24 hours notice. This courtesy on your part will make it possible for us to give the appointment to another patient who needs to be seen. We understand that situations may arise that would make it impossible for you to give 24 hour notice and each incident will be given consideration based upon your appointment history. Missed or broken appointments without notice may be charged to the patients account. The broken appointment fee is $50.00.
