Smile Makeovers

Cosmetic dentistry is one of the most cost-effective ways to improve your appearance. A beautiful, bright, healthy smile will increase self-confidence and overall life satisfaction. Cosmetic dentistry includes things like tooth-colored restorations, dental implants, and crowns.

We have many options, so please call us today!

Implants or Fixed Dentures

Dental implants are a great option for replacing missing teeth, improving chewing ability, eliminating bridges, and replacing traditional dentures. Implants can be used to secure a full set of removable dentures for people who have no remaining natural teeth.

Ask us about a free implant consultation.

Sleep Apnea Treatment

Obstructive sleep apnea occurs when the airway completely collapses, blocking airflow into the lungs. The harder one tries to breathe, the tighter the airway seals. This airway obstruction persists until the brain partially awakens the person, unconsciously closing the jaw and returning the tongue and throat to a normal position.

We offer effective, nonsurgical relief from sleep apnea and other sleep-related disorders — including snoring. Ask us how you can get the restful, healthy sleep you’ve been missing.

Composite Fillings

Read More

The common silver filling contains mercury. Our practice uses the highest-quality biocompatible, tooth-colored restorations to create healthy, beautiful smiles. Since the composite material adheres directly to the tooth enamel, less preparation of the tooth is required before using it. This means it is more durable and provides a more natural-looking result.

Crowns and Bridges

Crowns & Bridges

Read More

Protect and keep badly decayed or fractured teeth while maintaining a beautiful smile. Made to perfectly match the shape and shade of your other teeth, they’re durable, strong, and undetectable. Crowns should be placed before the tooth is so decayed that it may fracture. This can often help prevent the expense of root canal therapy in the future. If a tooth is too damaged to have a crown applied, a porcelain bridge may be a good alternative.



Read More

Gum disease is treated by carefully removing the bacteria and substances that form in the pockets around the teeth. The removal of this material occurs on a microscopic level and requires great skill. Our dental team has had advanced training to effectively remove all of the bacteria.

Porcelain Veneers

Porcelain Veneers

Read More

Veneers are very thin porcelain pieces that are custom made to adhere directly to the front of teeth without grinding or shaving. Transform your smile without drilling on your natural teeth! In the hands of a highly skilled dentist, porcelain laminates can provide you with an incredibly natural, beautiful smile. They are virtually undetectable and can dramatically improve your appearance. They are durable and long-lasting when compared to other cosmetic treatments.


Protective Sealants

Read More

Normal pits and grooves on the chewing surfaces of back teeth can trap food that can’t easily be removed with brushing. A sealant is a tough tooth-colored material that is designed to bond to tooth enamel. These sealants are painted on to the tooth surface to seal these pits and grooves and protect against decay. We recommend applying these to children’s teeth once they have permanent back teeth in place. They can also be useful to adults in some situations.

Smile Whitening

Smile Whitening

Read More

Many everyday things like coffee, tea and wine can significantly dull teeth. Smile-whitening enables us to significantly brighten your smile for that dazzling white smile you deserve. Plastic whitening trays will be made from models of your teeth. You will then place a special whitening gel in each tray and wear the trays in your mouth for several hours per day. (Many patients wear their trays after dinner and before bed.) A significant change in tooth color is usually seen in just four to six weeks.

Digital X-Rays

Digital X‑Rays

Read More

Our use of digital x-ray technology reduces your radiation exposure and eliminates the use of chemicals. It’s better for you and the environment. It's also easy for you to see what the doctor sees. Your digital x-ray can be seen on a computer screen located next to your dental chair. This helps you understand your needs and make informed choices about your treatment.

Root Canals

Root Canals

Read More

Root canal therapy is an excellent way to save a tooth that would otherwise die and need to be removed. All teeth that have had root canal therapy must be protected with a crown. This is because teeth that have had the pulp removed are more susceptible to fracture.
