We value you and appreciate your interest in our office. We would like the opportunity to answer your questions personally, so feel free to give us a call!

Does your office accept new patients?

Dr. Knight accepts new patients with or without insurance. Our office requires a patient to have a new patient comprehensive exam, prophylaxis (cleaning), and x-rays for their first visit. This will establish them as a patient in our office and we will be able to meet their dental needs better if an emergency arises.


Are there payment options?

As a courtesy to our patients, we will send claims to insurance. We ask our patients to be prepared to pay at the time of service for the portion that insurance does not pay. If arranged in advance we can accept payment up to 30 days after insurance has paid.

Our office also offers several payment options. We accept Visa, MasterCard, Discover, and American Express. A payment on account can be made directly to us by use of our website to a secure location; you can submit your credit card information on your billing statement or by phone.

Financing can also be offered through CareCredit. They are a healthcare finance company that offers up to 12 months interest free financing or 2, 3, or 4 year financing at 14.99% interest OAC.


Does Dr. Knight take my insurance?

Dr. Knight is a contracted in-network provider for many different insurances and plans. Some insurance companies have a list of providers on their website. This can be misleading because they may list Dr. Knight as an in-network provider when he is only on certain plans. The best way to determine if your dental insurance company will pay for services with our office is to call them and ask if they list Dr. Knight as an in-network provider for your plan.


How much will my insurance pay?

Each dental insurance plan varies for what they allow and will pay. Payment will be determined at the actual time of service by your insurance company upon receipt of the claim and by your specific plan provisions. However, we can try to give you an educated guess as to what your insurance may pay for any given procedure. The best way to find out what your insurance will pay is to allow us to send your dental insurance a pre-determination of services. They will usually respond within 10 days to 4 weeks. If we need the estimate sooner we can make a phone call on your behalf and ask one of the dental insurance customer service representatives. These estimates will not be a guarantee.


If I need to get a cavity filled, which type is better: white or silver?

Choosing silver or white fillings is a personal choice. Both types of fillings are used to restore decayed areas of teeth. Dr. Knight does not prefer one type over the other. However, our experience has shown that the metal amalgam fillings tend to last longer and wear better but many patients concerned with the aesthetic appearance of the filling will choose to have a white filling. Tooth-colored fillings (made of dental resin) are frequently used on all teeth and are recommended for restoring decayed areas on visible surfaces of teeth.

Metal amalgam (silver) fillings, although not used often, are used mostly for back molar teeth. Some dental insurance companies will only pay the metal amalgam rate for dental restorations on back molar teeth. This may leave the patient with the responsibility of an additional co-pay if they choose to have a white filling on a molar tooth. This usually amounts to between $30 and $40.


What method of teeth whitening do you recommend?

Dr. Knight recommends the at-home teeth whitening options of either personal dental trays or professional prescription strength disposable strips or trays. Both types of whitening are effective.

Personal trays with the higher concentration of bleach have a tendency to whiten quicker.

Personal trays are made specifically for the patient in our office from teeth impressions. They include bleach that ranges from 16% to 35% depending on the patients level of stain and discoloration always taking into account the patient’s history of teeth sensitivity. This method has a higher initial cost for making the trays. Most patients prefer the whitening trays that are made specifically to fit their teeth.

The at-home disposable professional prescription strength strips or trays that are the one-size fits all type can only be purchased from a dental office. “Free – in office” teeth whitening is not offered by Dr. Knight.


What is “happy gas” and what does it do?

Nitrous oxide, commonly known as “happy gas” or “sweet air”, is a chemical compound with the formula N2O. It is an oxide of nitrogen. At room temperature, it is a colorless non-flammable gas, with a slightly sweet odor and taste. In 1963 Nitrous Oxide made its debut as a generally accepted method of anesthesia.

Nitrous Oxide is used in dentistry for its anesthetic and analgesic effects. Many patients feel that the “happy gas” allows them to relax and calms anxiety that they often have with a dental visit. “Happy gas” when used is in addition to the anesthetics used to numb. Administration of the “happy gas” is with an analgesia machine. This is an automated machine designed to deliver a precise dose and breath-actuated flow of nitrous oxide mixed with oxygen, for the patient to inhale safely.


How long does the “happy gas” affect me and is it safe for me to drive after having it?

Nitrous Oxide is completely out of your system in three minutes after removing the automated breathing apparatus. You will be asked to sit for a couple of minutes so you are not unstable on your feet. The calmness you felt while on the “happy gas” may stay with you being a pleasant after effect. By the time you leave our office the Nitrous will be out of your system and you will be able to drive.
