We Offer A Full-Range of Services


Dr. Barnum employs a phenomenal hygienist to help take care of your cleaning appointments including standard cleanings as well as more advanced Scaling and Root Planing procedures to treat Periodontitis.

We use a variety of methods to clean your teeth.  We usually start with a quality ultrasonic instrument that “shakes” and shoots out water.  This is the most gentle and efficient method of debriding teeth.  However, this instrument is not sufficient to fully clean your teeth, and the next step is to use special hand instruments.  After the hand instrumentation you will receive a polish, a flossing and (depending on your preference,) a fluoride treatment.

When there is disease present around the teeth, gums and bone (known as Periodontitis,) we are also qualified to perform Scaling and Root Planing (otherwise known as a “deep cleaning.)  This is a procedure which is broken up into several appointments, involves anesthetic, and requires a highly skilled person to perform.


At your cleaning appointment with the hygienist, the doctor will also examine your oral health.

Digital X-rays

Our office uses a low radiation digital x-ray system that shows the image on a computer screen.  Digital x-rays are much quicker than the older method, expose less radiation, and allow the patient to view the image on a computer screen.  When there is a problem with a tooth, we are confident you will be able to see it as well.


Sealants are used to fill in deep grooves on teeth that are at higher risk for developing a cavity.


There are several types of filling materials we utilize depending on the circumstance.  Almost all the fillings we place are done using white materials. We also use gold, and in rare circumstances “amalgam”.  It is important you have a choice in the matter.


A crown (sometimes referred to as a cap,) covers a heavily damaged tooth.  A crown will restore the function and form of your tooth.  You have several different materials to choose from, and although Dr. Barnum will make a reccomendation, you have the final say in the matter.  The different materials to choose from include: all white (or porcelain;) gold, or a combination of the two. There are pros and cons depending on the circumstance, and you will have the time to consider all before making a decision.


An implant is basically a titanium screw with is placed into the jaw bone and replaces the root of your missing tooth.  There are two components that are placed on the top of your implant: the abutment and the crown.

Partials & Dentures

When there are some missing teeth (not all,) a partial is an option to replace them.  Partials are technically called  a removable partial denture.  There are all “plastic” partials which are used in a more temporary fashion, and there are metal framed partials which are meant to last a long time.  The partial is designed to utilize the remaining teeth to stay in. Dentures (otherwise known as a plate or false teeth,) are used to replace all the teeth.


There are two avenues you may take to become a patient.


1.  If you are not having any issues and just need a check up and cleaning, then schedule a new patient appointment (x-rays, cleaning, exam.)

2.  If you are having an urgent dental need, please state this when making your first appointment so we may  take care of this first, and then we’ll schedule your new patient appointment accordingly.  We will usually need to see you for 15-30 mins. to figure out what you need and want.
