Sleep Apnea

Experience the sleep you’ve always wanted

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 Dr. Kathleen Winn how you can get the restful, healthy sleep you’ve been missing.

Life-Changing Implants

Confidence In Your Smile

Dental implants are a permanent, natural-looking solution to replace a missing tooth. Dental implants bond directly to the jawbone by attaching a titanium post and connector to create a sturdy base for the crown. Though Dr. Kathleen Winn does not place the implant herself, she will restore the implant crowns and implant-supported denture. Dental implant restoration with Dr. Winn is an excellent solution for those who want to improve their smiles while allowing the lifestyle they’re accustomed to.

Restorative Dentistry

Dr. Kathleen Winn believes that preventive care is the foundation of everything she does. While it’s tremendously exciting to restore someone’s smile and function so they can eat again, it’s more rewarding to keep her patients healthy.

Smile Whitening

Tooth Whitening is an easy solution for people who want to improve the color of their teeth with minimal procedures. Remove stains from coffee, smoking, or other common causes with a painless tooth whitening from Dr. Kathy Winn. We offer a take-home tray for tooth whitening, which will be more effective than any over-the-counter solution. The whitening agents we use typically lighten your teeth up to ten shades from the comfort of your own home.
