Dear Ms. Mitchell,
This is a friendly reminder that you have a dental check-up booked at Bright Smile Dental Clinic. We are writing a little early so that you have plenty of time to prepare and to change the date if you need to.
Your appointment is on Thursday, April 17, at 3:30 p.m. with Dr. Evans. Please try to arrive about ten minutes early so that you can fill in a short health form at the front desk. The check-up should take around thirty minutes. If your teeth need any extra treatment, Dr. Evans will explain everything and arrange another visit.
Please remember to bring your insurance card. If you cannot keep this appointment, kindly call us at least 24 hours in advance so that we can offer the time to another patient. There is a small fee for appointments that are missed without any notice.
As always, please brush gently before you come, but there is no need to do anything special. We look forward to seeing you and helping you keep your smile healthy.
Best regards,
The Bright Smile Dental Clinic Team
