Preventative Dental Cleanings
We offer preventive care to maintain healthy teeth and gums. Professional dental cleanings are one of the most important steps you can take to protect your oral health. Routine cleanings are part of a bi-annual preventative care exam that helps keep teeth and gums healthy.
During a cleaning, one of our trained hygienists thoroughly cleans your teeth, polishes away surface stains, and may apply fluoride to help prevent cavities. More importantly, these visits include a complete oral exam. A routine exam lets the dental team spot early signs of gum disease, tooth decay, and other conditions before they become more serious.
We recommend that you combine professional cleanings with a good at-home routine. Our office wants you to stay healthy at home and in our office.

Gum Disease Treatment
Gum disease is an infection of the tissues that hold your teeth in place. It is caused by plaque buildup. Early signs include red, swollen, or bleeding gums. Left untreated, gum disease can lead to tooth loss.
Dr. Cain provides both non-surgical and surgical treatments to stop gum disease and restore your oral health. He uses advanced techniques to remove bacteria and infected tissue while saving as much healthy tissue as possible.
Pinhole Gum Rejuvenation
Traditional gum graft surgery involves cutting tissue from the roof of your mouth and stitching it onto receded gums. This can be painful and requires weeks of healing.
Dr. Cain offers the Pinhole Gum Rejuvenation procedure. This minimally invasive technique uses small holes to loosen and reposition existing gum tissue. There are no cuts, no stitches, and much faster recovery. Most patients return to normal activities within a day or two.
Dental Implants
Dental implants are the best solution for missing teeth. An implant is a small titanium post placed into your jawbone. It acts like a natural tooth root. Once healed, a crown is attached to the implant. The result looks, feels, and functions like a real tooth.
Dr. Cain has placed thousands of implants over his 25-plus-year career. For patients missing several teeth, he can place implant-supported bridges. He also offers All on 4, which uses as few as 4 implants to support a full arch of teeth.
Bone Grafting
When teeth are missing, the jawbone can shrink or deteriorate. This makes it difficult to place implants. Bone grafting rebuilds the bone to create a strong foundation. Dr. Cain uses advanced bone grafting techniques to prepare your mouth for implants.
Laser Periodontal Therapy
Dr. Cain uses dental lasers to treat gum disease with less pain and faster healing. Lasers can remove infected tissue and bacteria while leaving healthy tissue alone. Many patients prefer laser therapy because it is less invasive than traditional surgery.
