Frequently Asked Questions

Scheduling and Billing:

What Insurance Plans are you contracted with?

Our office is contracted with several dental insurance plans and we accept any dental insurance plan that allows you to choose your own dentist. If you’re not sure about your plan, contact our office and we will be happy to research your plan and assist you with any questions you may have!

Will you bill my insurance?

As a courtesy, our office will assist in billing your dental insurance plan. Our office will provide an “estimate of benefits” for your treatment based off the information we receive directly from a representative of your plan. If they do not pay exactly what is estimated, you will be billed for any amount not covered by your plan.

How many doctors practice at the two offices?

Desert Vista North - Dr. Smith and Dr. Javia./p>

Desert Vista West - Dr. Collier and Dr. Smith

Do you accept any HMO or AHCCCS Plans?

No, we only accept PPO plans.


How frequently do I need to have x-rays taken?

It is our office policy to take a full mouth X-ray set every 3-5 yrs and bitewing X-rays once a year. This is only a guideline. In some cases, there may be a need for additional X-rays. This will be recommended on an individual basis.

Will insurance cover my periodontal therapy?

Most insurance plans help pay a portion of periodontal therapy, but like any other dental procedure, we are always available to give an “estimate” of the patient’s portion. We will also send a pre-authorization to your insurance.

Why do I need more than two cleanings a year while on periodontal maintenance?

Once you have undergone Scaling and Root Planing (SRP), you are placed on a maintenance cleaning schedule. This means you will be coming to see your dental hygienist every 3-4 months. This is mainly based on the individual frequency of calcium build-up that occurs in your mouth. The faster we can have this build-up removed, the better the results of your oral health care will be. This will also help prevent any further need for deep scaling appointments.

Is it normal that my teeth stain after using Chlorohexadine mouth rinse?

Yes, it is one of the side effects to using the rinse. However, we believe the benefits outweigh the effects. The staining can be removed with the help of your hygienist.

Once I have had Scaling and Root Planing (SRP), will I ever have to have it again?

That is dependent on the individual and how severe your periodontal situation is.

What is the laser therapy that is performed in conjunction with scaling and root planning (SRP)?

A diode laser is used after the scaling and root planning procedure has been complete. The laser is used to sterilize the periodontal pockets and remove any infected tissue. This allows for the tissue to reattach to the bone and reduce the pocket depth.


What is the difference between a filling and an onlay?

A filling is acceptable when less than 50% of the tooth structure is compromised with either decay or an old restoration. If a tooth has over 50% of tooth structure missing due to decay or failing restoration, a routine filling material is not strong enough to properly restore the tooth. Onlays are considered a conservative option when restoring your tooth. It is a restoration that is stronger than a filling material but more conservative than a crown.

How long will I be numb?

People react differently to medications. Most people experience residual numbness anywhere from 2-6 hours after the injection.

Why do I need to take another X-ray for my crown, root canal, onlay or extraction when I just had X-rays at my cleaning appointment?

Typically at your re-care visits with your hygienist, bitewing X-rays are taken. These X-rays allow us to see in between the teeth and help us diagnose any decay. However, this type of X-rays does not show the full tooth and the root surface.

A periapical X-ray shows the entire tooth, helping us to determine if there are any underlying periodontal problems or abscesses present. Most insurance companies also require this X-ray when submitting claims.
