Our Services

The following is an overview of our main services. For additional services not listed here, please contact our office.


Composite (Tooth-Colored) Fillings

Composite is a type of filling material that is both esthetic and durable and allows the dentist to conserve as much tooth structure as possible when preparing the tooth. When placing a composite restoration, a bonding agent is applied to facilitate the seal between the tooth surface and the composite material. The filling is hardened with a curing light, giving the patient the ability to return to normal eating and drinking as soon as possible.



A crown, or cap, rebuilds a tooth to return optimal contour and function. It acts like a helmet, surrounding the natural tooth structure, to protect its strength and allow normal eating. Generally crowns take 2 appointments. During the first appointment the tooth is prepared, an impression is taken and a temporary crown is made. The final custom-made crown is tried in and cemented at the second appointment. Crowns may be made of porcelain, metal or a combination of these. Though crowns cover the majority of the tooth structure, it is still important to care for them as though they were natural teeth. Crowns can get decay and fail over time if not properly cared for.



Caring for Your Dentures

Removable Complete Dentures

Removable Partial Dentures


Dental Hygiene


Digital Radiographs (X-Rays)

Digital radiographs are both a safe and effective way to assist your dental care team in evaluating the health of your teeth, jaws, bone and the supporting structures of your mouth. Bitewing x-rays, generally recommended every 12-24 months dependent on your individual risk factors, assist in diagnosing decay, "watch" areas and the quality of bone support between your teeth. A full mouth series or panoramic x-ray, provides imaging of the root structure of your teeth, bone quality, and jaws, as well as providing an assessment for development and potential pathology.





When a tooth has become extensively damaged and cannot be saved, an extraction is needed to prevent further breakdown, pain and infection. Local anesthetic is given to numb the area and pressure is applied to remove the tooth from its socket. Once removed, the area is cleaned. Sutures, or stitches, are sometimes needed to assist in the healing of the area. Your dentist will review care instructions with you to promote optimal healing of the extraction site.

Fluoride, a naturally occurring ion, helps to rebuild or remineralize weakened tooth enamel. This strengthens the tooth structure and can assist in repairing early signs of decay and prevent new cavities from forming. Brushing twice a day with a fluoride toothpaste and flossing daily is the best way to care for your teeth at home. Talk to your dental professional to see if additional fluoride is recommended for your individual needs.





Occlusal Guards & Nightguards
An occlusal appliance, or night guard, is a device worn in the mouth overnight to separate the top and bottom teeth from wearing against one another. It slightly repositions the jaw to promote relaxation of the jaw joints and muscles while protecting teeth from the forces created by clenching and grinding.

Athletic Mouthguards
Athletic mouthguards are custom made to protect your teeth, gums, and jawbone. Generally these are recommended for anyone, kids or adults, playing a contact sport that poses a risk of mouth or facial injury.


Nitrous Oxide (Laughing Gas)

Laughing gas is an analgesic, or anxiety reducing, substance that may be used during dental treatment. A nasal canula or nose piece is connected to a pump that delivers a mix of oxygen and nitrous oxide. A relaxed or calming feeling is experienced by those that use nitrous oxide, though sometimes tingling in the fingers and toes or a floating sensation is felt. Once the dental procedure is completed, pure oxygen is delivered for 5 minutes to flush out residual nitrous oxide. The effects dissipate almost immediately and one is able to drive home after its use.


Periodontal Disease


Scaling and Root Planing

Post-Operative Instructions


Replacing Missing Teeth

There can be several options to replace a missing tooth or teeth depending on the location in the mouth. The gold standard for tooth replacement is a dental implant, think of this as a prosthetic tooth root that sits within the jaw bone. An implant is restored with an abutment and a crown that look and function like natural teeth. A bridge is an alternative method of tooth replacement. Here, adjacent healthy teeth are capped and used to support a fake tooth. Bridges are cemented in place. The final option for tooth replacement is a removable appliance. This option also relies on the adjacent healthy teeth for support but is taken out at night and after meals to clean and give your tooth and gums a rest.


Root Canals

A root canal is needed when the nerve and/or the base of the root(s) of a tooth become infected. This procedure allows one to save and maintain their tooth. A small access is created on the biting surface of the tooth and a series of files are used to clean out the roots. Cleaning solutions are used to ensure that the root canals are as flushed out as possible. Finally, a biocompatible filler is placed to seal off the root structure. Once completed, a filling, post, crown or a combination of these are used to restore the access point of the tooth and protect the remaining structure.

Teeth Whitening

White Smiles for Life Program
White Smiles for Life is our patient whitening program. Anyone can enroll provided their mouth is healthy enough to withstand tooth bleaching*. After enrolling in the program, one receives either custom whitening trays with bleaching gel or Opalescence Go trays each time they come in for a regular cleaning and check up.

*Please note: dental restorations such as fillings and crowns will not lighten with tooth whitening. Additionally, some internal causes of tooth discoloration, such as tetracycline staining, root canal treated teeth, and developmental anomalies, may not respond to traditional tooth whitening.
To receive the whitening gel, one must be absent of dental and periodontal disease.
