Dental Treatments

Dry Mouth

Dry mouth (xerostomia) is a condition of having low saliva production.  Dry mouth can contribute to tooth decay, causing it to progress very quickly. Untreated, dry mouth can also contribute to bad breath.

Dental Sealants are applied to protect teeth from decay. A dental sealant is a material applied to the chewing surfaces of the molars.

The sealant material flows into the pits and grooves on those surfaces and acts like a barrier from bacteria decaying the tooth’s outer surface, the enamel.

See our Pediatric Dentistry page for more information.


Fluoride is a mineral that helps make teeth stronger and protects them from decay. Fluoride is also in anti-cavity toothpastes and mouth wash and supplements may be recommended if you are on well water.

Fluoride is used to reduce the pain caused by exposed root surfaces with receding gums. Regular fluoride application helps eliminate root sensitivity.


Composite Fillings are tooth colored so you will no longer have metal fillings showing in your teeth and they are as strong as the metal fillings. Decay is removed and strong adhesive is applied before the filling is added to restore your tooth to its natural color and function.


Temporomandibular Joint Dysfunction (TMJ)

TMJ Dysfunction involves your jaw joint along with the muscles used in chewing. Most patients can be treated quickly and effectively with simple therapy.

  • TMJ also goes hand in hand with Bruxism.
  • Untreated, it can lead to pain, joint damage and tooth loss.
  • Early treatment  will save you money.


Bruxism is often referred to as clenching or grinding.

Bruxism and TMJ may be the cause of headaches or jaw pain from clenching or grinding at night. Consequences of not treating your TMJ and Bruxism (often related) can lead to:

  • joint damage,
  • muscular pain,
  • notching of teeth,
  • cracking of teeth,
  • severely worn teeth.
  • and tooth loss.


Mouth Guards

  • Night guards to prevent trauma from tooth grinding or clinching.

Sports Guards

  • Custom mouth guards for sports as protection for dental injury.
  • Make your sport guard part of your uniform.

Sleep Apnea

If you are suffering from the effects of snoring or have compromised sleep because of breathing problems at night, talk to us about the Watermark ARES™ at-home testing kit. We offer a FREE initial consultation for sleep apnea patients that includes testing and risk factor assessment.

Periodontal Treatment

Periodontal Disease frequently can be treated effectively if identified early before severe bone loss occurs. It is a complex disease which has been closely linked to heart disease, low birth weight babies, smoking and to other human conditions.

See our Patient Education Center for videos and more on this topic.

How Periodontal Disease Develops

Bacteria in your mouth create plaque build up causing gum inflammation, bleeding,  gum and/or bone loss. Risk factors that promote bacterial growth include smoking, poor brushing, and inadequate flossing habits. A complex reaction with your immune system  may increase your inflammation.

We strive to prevent gum disease, but can treat it in the early stages.

Our Goals

  • Early detection & treatment.
  • Customize your treatment plan according to your condition.
  • Improve your home care.
  • Establish a 3 or 4 month periodontal maintenance program according to your condition.
  • Referral to a Periodontist, if needed.

Consequences of Untreated Periodontal Disease

Bacteria and plaque along with a complex reaction with your body’s chemistry and immune system, lead to inflammation, bleeding, gum and bone loss. Your risk factors increase the severity and progression of your periodontal disease.

Overcoming Periodontal Disease

Early intervention saves your teeth, time and money. Treating gum disease is similar to building the foundation of a house. Without a good solid foundation, the rest of your treatment will fail. Let us evaluate you and see if we can help you in our office. Schedule an appointment for a comprehensive exam and periodontal treatment.

Consequences of Bone Loss

  • Begin with an initial deep cleaning with anesthesia. See the Comfort Measures section of the Patient Information page.
  • Removal of the infection, plaque / bacteria around your teeth.
  • Periodontal therapy visits every 3 to 4 months with a hygienist.
  • Evaluate your response to the deep cleaning.
  • Decrease gum bleeding.
  • Decreased pocketing
  • Evaluate your home care.
Gum disease is a lifelong battle that requires exceptional home care Referral to a Periodontist for surgery and adjunctive therapy may be necessary and you may be referred immediately depending on your disease.
  • Many teeth have nooks and crannies where bacteria can hide.
  • Bacteria accumulate in these areas.
  • Bacteria become destructive to gum / bone in about 3 months.
  • The hygienist removes bacteria from the places that you are unable to clean at home.
  • Pockets over 4 mm.
  • Concavities on root surfaces and between roots.

With 3 to 4 month cleanings, we keep bacteria from becoming destructive, this enables bone and gum preservation.

If you respond well:

  • We will treat the remaining problems in our office.  You will use home rinses and  brushing aids.
  • We may use limited Arrestin placement. This is  an antibiotic treatment placed in the infected gum.
  • We will recommend hygiene  (cleaning) appointments every 3-4 months to continue care.

If you do not respond well:

Dr. Kitzmiller will refer you immediately to a Periodontist for further evaluation and treatments such as:

  • Bone grafting
  • Laser surgery (LANAP)
  • Gum grafting
  • Other procedures which we cannot provide comfortably here.

Detailed plans from our specialist will be prescribed for you with further evaluation of complex risk factors.

Wisdom Tooth Removal

We offer extractions for wisdom teeth for those patients who do not require IV sedation or are very nervous.

The shape of the tooth, closeness to the nerves and blood vessels, length of the root, location of the sinus, and age of the patient are factors which contribute to whether an extraction should be referred to an oral surgeon.

Comfort Measures

We offer comfort measures for anxiety and pain control that other dentists in the Apex, Morrisville, Cary area do not offer.

Root Canals

Comfort Measures

Headsets, Nitrous Oxide & More


Treatment of the “Root Canal” system (endodontic therapy) involves cleaning of the canal which is located in the middle of the root. Bacteria get inside, destroy the nerve and create an infection inside the tooth. Often the pain is unbearable. The infection spreads out the tip of the root and enters the bone. Sometimes the infection will drain out through the gum, but sometimes it may drain into deeper areas of the head and neck which may be life threatening.

OwlVisit our Patient Education Center for videos and more on this topic.

Our Goals

  • Remove the infection from the root canals inside the tooth.
  • Eliminate the pain associated with a dying nerve or infection.
  • Promote healing for the bone around the tooth.
  • Stabilize the tooth to get it ready for a crown.

How do we clean out the infection inside the canals?

The canals are accessed through the top of the tooth. Titanium files and solutions are used to loosen and remove the infection. The canal space is then filled with Gutta Percha, a soft, flowable, flexible material.

Once the canals are disinfected and filled, the bone heals and the tooth feels better.

Steps in the Root Canal

  • Open the tooth through the exposed surface
  • File out the decay
  • Fill
  • Cap with a crown

Options for Root Canals

Extraction – Many factors make Root Canal treatment less likely to succeed. These may include root fracture / splitting, and difficult canals to fill which have extreme shapes and curves. Multiple costs in addition to the Root Canal itself may make it cost prohibitive. To stop the spread of infection, the tooth can be removed and the infection cleaned out.

Extraction, Bone Graft & Implant – Dental implants may provide a very conservative replacement for your teeth. Implant success rates are beginning to surpass Root Canals.

Extraction & Bridge – A bridge is a quick and simple way to hold the space for a missing tooth. Visit the bridges page to learn more.

No treatment – While this is an option, failing to treat can lead to more pain, severe infection and potential life threatening outcomes. It is generally not recommended.

  • A root canal preserves the tooth for chewing, speaking and smiling.
  • It holds the space so other teeth can’t drift and move.
  • It is a conservative treatment with the goal of preserving your natural tooth.
  • A root canal has a success rate of 85 to 90% depending on your situation.
  • In order to remove the infection from the tooth, an opening is made in the top of the tooth and weakens it.

  • To strengthen the tooth, 2 additional procedures will need to be completed: a core build up (fills the root canal opening) and crown (“cap” to hold the tooth together). Inquire about the total cost before you proceed. Apex Dental Group uses CEREC dentistry which differs from other dentists in the Apex, Cary, Raleigh, NC area.

  • If the cavity was into the nerve and down to the bone, it may require bone surgery and further increase cost.

  • Deep cavities close to the bone may need crown lengthening. This is where there is not enough of the tooth is exposed to do a crown properly after the root canal. Ask about if CEREC crowns in a day at Apex Dental Group are an option.

  • Some teeth that need root canals may be difficult or not possible to clean. They may not be able to be treated.

Apex Dental Group in Apex, NC specializes in CEREC ® dentistry. The video below shows a root canal procedure, but in our office your root canal and crown is completed in one day with CEREC Crown in a day technology.
