Office Policies & Mission

Our Mission

At the office of Dr. Mary Davis and Dr. Ella Miller, we are committed to providing our patients the highest quality dental services, using state-of-the-art technology, in a caring, comfortable and professional setting.

Our team of quality professionals and experienced staff are focused on meeting the needs of our patients, referring dentists and community.

Office Hours

We are open to serve you, answer questions or schedule an appointment during the following hours:

Monday – Thursday: 7 a.m. – 3 p.m.


Appointments are an important part of your treatment, as time has been reserved specifically for you. Please arrive on time for your appointment. If you are more than 15 minutes late, you might be asked to reschedule your appointment.

Appointment Rescheduling Cancellation Policy: Out of respect for other patients who are needing prompt care, we request a 24-hour notice for all appointment changes. A minimum of $25 will apply if an appointment is cancelled within 24 hours. We wish we did not have to do this, but it is necessary to keep treatment costs down for everyone.


Our office is committed to helping you maximize your insurance benefits. Because insurance policies vary, we can only estimate your coverage in good faith but cannot guarantee coverage due to the complexities of insurance contracts. Please inform us of any changes to your insurance coverage.

Your estimated patient portion must be paid at the time of service. As a service to our patients, we will bill insurance companies for services. If claims are not paid within 60 days, you are responsible for the balance. If you have any questions, our courteous staff is always available to answer them.

No Surprises: What’s a “Good Faith” Estimate?

If you don’t have health insurance or you plan to pay for health care bills yourself, generally, health  care providers and facilities must give you an estimate of expected charges when you schedule an  appointment for a health care item or service, or if you ask for an estimate. This is called a “good faith  estimate.”  

A good faith estimate isn’t a bill 

The good faith estimate shows the list of expected charges for items or services from your provider or  facility. Because the good faith estimate is based on information known at the time your provider or  facility creates the estimate, it won’t include any unknown or unexpected costs that may be added during  your treatment. Generally, the good faith estimate must include expected charges for: 

  • The primary item or service  
  • Any other items or services you’re reasonably expected to get as part of the primary item or service  for that period of care.  

The estimate might not include every item or service you get from another provider or facility, even if  some items or services may seem connected to the same service. For example, if you’re getting surgery,  the good faith estimate could include the cost of the surgery, anesthesia, any lab services, or tests.  

In some cases, items or services related to the surgery that are scheduled separately, like certain pre surgery appointments or physical therapy in the weeks after the surgery, might not be included in the  good faith estimate. You’ll get a separate good faith estimate when you schedule those items or services  with the provider or facility, or if you ask for it.  

Your right to a good faith estimate 

Providers and facilities must give you the good faith estimate: 

  • After you schedule a health care item or service. If you schedule an item or service at least 3  business days before the date you’ll get the item or service, the provider must give you a good faith  estimate no later than 1 business day after scheduling. If you schedule the item or service OR ask  for cost information about it at least 10 business days before the date you get the item or service,  the provider or facility must give you a good faith estimate no later than 3 business days after you  schedule or ask for the estimate. 
  • That includes a list of each item or service (with the provider or facility), and specific details, like  the health care service code. 
  • In a way that’s accessible to you, like in large print, Braille, audio files, or other forms of  communication. 

Providers and facilities must also explain the good faith estimate to you over the phone or in person  if you ask, then follow up with a written (paper or electronic) estimate, per your preferred form of  communication. 

Keep the estimate in a safe place so you can compare it to any bills you get later.

After you get a bill  for the items or services, if the billed amount is $400 or more above the good faith estimate, you may be  eligible to dispute the bill.
