Joan Loves

Her New Smile

Joan had worn teeth, staining, and discoloration. Dr. Keene suggested crowns instead of veneers due to the excessive wear. With the crowns placed, Joan has a new lease on life with a beautiful natural smile that makes her look years younger. She’s got her confidence back and loves to share her smile with others!

Chao Pinhole

Surgical Technique®

How Does the Chao Pinhole Surgical Technique® Work?

Traditional gum recession treatments involve the use of donor tissue or soft tissue grafts in order to rebuild the gumline. This involves suturing the soft tissue into place so it can heal onto your existing gum tissue.

The Chao Pinhole Surgical Technique uses a small needle to pierce the patients existing gum tissue. This small hole allows specialized instruments to gently loosen existing tissue and allows the gumline to expand and cover the exposed root structure.

There are no grafts, sutures or incisions needed when using this new technique. It simply involves an adjustment of the patients existing gum tissues.

Implant Dentistry

Dental implants are a great option for replacing missing teeth, improving chewing ability, eliminating bridges, and replacing dentures.

Several implants may provide a base for a series of artificial teeth known as a fixed bridge. Implants can even be used to secure a full set of removable dentures for people who have no remaining natural teeth.

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.

Implant Dentistry

Cosmetic Dentures Read More

A well made denture is not only comfortable and functions properly; it also allows the wearer to smile with confidence, knowing that their smile is no different than it would be with natural teeth. Creating a cosmetic denture is really an art in the hands of a skilled dentist like Dr. Keene.


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.

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.

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.

Composite Fillings

Composite Fillings Read More

The common silver filling contains mercury. Dr. Keene 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.

Periodontal Therapy

Periodontal Therapy 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.
