He is truly interested in and cares about each patient. In the evening, he calls each patient who received anesthetic or had an extensive procedure performed that day.

Services Provided layers

+ Cosmetic Dentistry
Dr. McMahan has had extensive experience and specialized training in performing cosmetic procedures such as bonding with porcelain veneers, space closure, teeth whitening, and improved esthetics in crowns or bridges using the latest materials and techniques.

He has successfully treated thousands of patients who desired to improve their smiles and self-esteem. Ask about any options you might have for enhancing your smile. The choice will always be yours, and your options will be fully explained.
+ Dental Implants
Dental implants are possibly the most exciting breakthrough in dentistry in the last 100 years! A dental implant is a titanium cylinder placed in the space once occupied by a missing tooth. The bone loves titanium, and it grows abound the implant in a matter of months to allow the implant to become a stable platform to support an abutment and a crown to replace the missing tooth.

An implant can also be used to support a troublesome denture, provide attachments for removable partial dentures, or even replace the entire dental arch with multiple implants and teeth attached. They are truly a remarkable option that can eliminate the need for bridges attached to the remaining teeth that require cutting on those neighboring teeth.

Dr. McMahan has been restoring implants for over 15 years. He received training at WhiteCap Institute under the direction of Dr. P. K. Clark in the placement of implants as well. He has been placing them for over five years now, and most cases they can be performed entirely at our clinic, without referring the patient to a specialist out of town. Dental implants generally will last longer and will be more comfortable and trouble-free than conventional bridges.

Our goal is for patients to never need an implant by keeping all of their natural teeth. However, tragic accidents can happen, and a missing tooth can now be effectively restored by placing dental implants without damaging neighboring teeth. We will always discuss this and any other options for replacing missing teeth or for securing a troublesome denture.
+ Hygiene, Periodontics, & Oral Systemic Health
Periodontal health refers to the health and condition of the teeth and their support system of soft tissue and bone. When poor hygiene and home care exist, tissues become diseased and inflamed, resulting in red, puffy gums that bleed excessively. Pockets develop under the tissues that accumulate even more bacteria, soft tissue attachment is lost, and bone support eventually recedes, leaving less bone around the roots of the teeth. Ultimately, teeth will be lost if no effective intervention occurs.

The best treatment for this condition is prevention! Our expert hygiene team will assist you in preventing this condition in the first place with great teaching and instruction as well as comfortable, efficient cleaning of the deposits on your teeth that can lead to periodontal disease. Regular recall visits every six months is the standard of care.

Aside from the obvious threat of tooth loss that periodontal disease can cause, more recent research shows that patients with active bleeding and inflammation in their mouth from any source results in a higher incidence of coronary artery disease, diabetes, kidney disease, and other systemic effects. By simply leaving diseased bleeding tissues untreated, means you could be more at risk for a heart attack!

We take this threat seriously, and we are actively involved in the American Academy of Oral Systemic Health (www.aaosh.org) in an effort to stay on top of research in this area and effective therapies and testing for risk. We employ the latest therapies, including laser-assisted periodontal care, ultrasonic instrumentation, and appropriate antibiotics upon testing, using genetic assays. Dr. McMahan and his staff stay up to date on current therapy, and they will consider your overall physical health, of which your teeth are an integral part.
+ Restorative Dentistry
Is a "filling" always just a filling? Not in today's world! Material improvements now allow teeth that have been broken, chipped, or suffered decay to be restored to their original form in a comfortable and esthetic way.

The two considerations in restoring or "filling" a tooth are proper form and proper function. Almost all restorations today are performed with bonded resin--tooth-colored materials called composites. There is rarely the need for any metallic restorations or crowns.

Dr. McMahan currently uses Zirconium oxide and E-max crowns that are some of the most durable and esthetic crown and bridge material ever produced. He is devoted to continuing dental education, and he is always looking for better treatment choices and material options, but the current material choices in composites and crowns and bridges are as close to ideal as they have ever been. The days of porcelain fractures on crowns or gold crowns are rapidly disappearing. Crowns today are milled from a digitized image at our lab, producing a crown that fits far better than previous cast metal crowns.

If you need a tooth restored, Dr. McMahan has the right material and knowledge to know the best way to restore it.
+ Endodontics
Endodontics refers to the treatment of teeth with a diseased pulp, more commonly known as root canal treatment (RCT). Dr. McMahan performs almost all needed endodontic care in his office without the need for referral to a specialist in most cases. We realize that nobody wants a RCT, and our goal is to prevent the need. However, deep decay, trauma, or cracks in teeth can lead to pretty severe pain that can only be relieved by removing the angry pulp.

The negative reputation that RCT has is actually related to the pain that sometimes precedes the treatment. RCT can be a life saver, and the relief or prevention of subsequent pain is a wonderful option to keep a tooth that might otherwise have to be extracted. Treatment is usually needed to prevent pain from developing, but there are occasions where the treatment relieves pain in marvelous ways.

Dr. McMahan has taken extensive training in the latest techniques and systems for performing RCT. The goal of completely removing the pulp in the canal system, disinfecting the space, and sealing the space from future bacterial infiltration can be accomplished painlessly and successfully in the majority of cases. Our goal is that you will never need a RCT, but in the event that it becomes necessary, we will take great care of you!
+ Technology
Dentistry has certainly changed during the span of Dr. McMahan's career. Dr. McMahan far exceeds the minimal requirement of 40 hours of continuing education every two years--in fact, he takes about three times that number. He loves doing dentistry, and he enjoys learning new ways to do it better.

Technological improvements are a large part of that. We have always invested in proven technology. We employed digital charting and radiography many years ago. We employ 3-D cone beam radiology, which allows for a three-dimensional view of teeth and bone, which aids in proper placement of implants and root canal therapy where canals can actually be visualized in three dimensions in a tooth.

Dr. McMahan routinely uses a CO2 Deka laser to aid in soft tissue manipulation and stimulation in many applications, resulting in far less recovery discomfort and quicker healing for the patient. Our crowns are produced using digital scanning technology, working as a team with expert dental labs in producing the best fitting crowns in the history of dentistry. We are always looking for ways to accomplish treatment more effectively and comfortably for the patient, and we will continue to acquire whatever technology is needed, as it becomes available.
