All-Porcelain Dental Crowns

Designed to match your natural teeth in color, shape, and size, dental crowns are a popular restorative treatment used by our cosmetic dentist Thomas G. Zarger. Dental crowns can be used to restore a tooth to its original shape, strengthen a tooth, or to improve a tooth's cosmetic appearance. Because the crown encases the visible tooth area, crowns are natural-looking restorations that restore function and aesthetics. 

Dental crowns can give strength and support to weakened teeth by acting as a splint that binds a tooth together. In many cases, this quality makes crowns a more effective treatment than composite fillings. If a less invasive option, such as porcelain veneers, dental bonding, or even teeth whitening, can effectively address your needs, Dr. Zarger will recommend the treatment that is best for you. If you would like to arrange a consultation or know more about dental crowns, contact our Knoxville cosmetic dentistry office, also serving Oak Ridge, Maryville, and Eastern Tennessee patients. Dr. Zarger can help you restore confidence and beauty to your smile.


Root Canal Therapy (Endodontics)

A smiling older man with gray hair Root canal therapy (or endodontic treatment) is performed to save a tooth when its pulp becomes injured or infected. Dental pulp, which provides the tooth with necessary nutrients and contains the nerves, is found at the center of each tooth. When a tooth's pulp becomes damaged, the tooth can become incredibly painful and will often die if left untreated. During root canal therapy, the damaged pulp is removed and the tooth is sealed. Because of improvements in anesthetics and techniques, the old stereotype of the painful root canal is a thing of the past.

Typically, root canal therapy is performed in two visits to our Knoxville office. During the first appointment, an anesthetic is administered and the affected tooth is isolated. The tooth's pulp is removed through a holed drilled in the tooth’s crown, and the root is cleaned and shaped. A temporary filling is then placed in the hole to prevent saliva from entering the tooth. In the next visit, the temporary filling is removed, the treated inner area of the tooth is filled with a resin-like substance, and the tooth is permanently sealed with a dental crown.

Despite the reputation of root canal therapy as being a painful procedure, most patients report little or no discomfort during treatment. Patients who need a root canal generally experience more pain prior to the procedure, rather than during or after. Root canal therapy usually eliminates or significantly decreases the pain.


Dental Bridges

A woman wearing a red sweater smiling into camera Missing teeth can create more problems than just an unattractive smile. The void left by missing teeth can hamper chewing and biting, cause problems with speaking, lead to movement of adjacent teeth, and cause changes in the shape of the face. If you have gaps in your smile, or if you must have a tooth removed due to injury or disease, a dental bridge can replace your missing tooth or teeth and restore your smile. With proper care, a dental bridge is very strong and durable.

Less invasive than dental implants, a dental bridge is essentially a false tooth fused between two dental crowns. The dental crowns fit over the teeth on either side of the missing tooth, and then the bridge fills the gap. The components of the bridge are made to resemble your natural teeth as closely as possible in color, shape, and size. Contact our Knoxville and Oak Ridge-area office for more information about dental bridges.

Many improvements have been made to dentures, and modern technology now allows us to customize them to perfectly fit your mouth for a completely natural look. Dentures can restore the natural shape of your face, give you a beautiful smile, and make eating enjoyable again. For more information about dentures, please contact us.


Periodontal Therapy

The first stages of periodontal disease, called gingivitis, are often painless and create few noticeable problems. Red, swollen, or bleeding gums are symptoms of the onset of periodontal disease. If caught early, periodontal disease often can be easily treated and any damage can usually be reversed. If left untreated, periodontal disease can lead to tooth loss and other serious dental problems, and treatment can be expensive and painful.

The best way to prevent periodontal disease or stop it in its early stages is to see Dr. Zarger every six months for a routine dental exam and cleaning and to brush and floss regularly. To learn more about periodontal therapy or root canal treatment, schedule an appointment with Dr. Zarger today. We offer Knoxville, Oak Ridge, and Eastern Tennessee patients the highest standard of dental care.


Family Dentistry

To help you achieve and maintain good oral health, we offer routine dental checkups and can monitor you during each stage of your treatment. Dr. Zarger recommends that children receive preventive care from an early age to ensure a lifetime of healthy teeth and gums.


Composite Fillings

They are safer than metal fillings, and they can be custom-tailored to match the patient's tooth shade and bite. Composite fillings are a durable solution for repairing either front or back teeth. Many patients prefer composite fillings to metal ones because they require less removal of the tooth material, they create less pain following treatment, and they can actually help strengthen the tooth's underlying structure. Contact our office to schedule a consultation and learn more about how composite fillings can be used to help improve your smile. 


Preventive Dentistry

Using preventive treatments like professional cleanings and exams, Dr. Zarger can identify any existing dental conditions and recommend the proper treatment. In addition, our team can help you develop effective at-home oral care practices like brushing and flossing. At our practice, we believe that it is never too early to establish good dental habits, and never too late to improve your dental routine.


Full Mouth Reconstruction

Unlike a smile makeover, a full mouth reconstruction can help you address both aesthetic concerns and functional issues such as missing teeth, severe decay, and periodontal disease.


Teeth Cleaning

Although proper brushing and flossing at home are essential for maintaining a healthy smile, a biannual cleaning is necessary to remove stubborn plaque and tartar to reduce your risk of gum disease and cavities. During your cleaning, our team will gently clean the surface of your teeth so your smile feels fresh and looks bright.
