The best of the past and the future…

Running Creek Dental represents the culmination of my lifetime of experience, skill, and care as a dentist.

I created this new, state-of-the-art dental facility from the ground up, not just to provide cutting-edge dental care but to change the way many people think about dentistry. My philosophy champions whole-body health, patient convenience, and safety well beyond all current standards. I embrace next generation technology (or, as we call it, Next Gen Tech) because it manages pain and shortens appointment times. Your trust and investment in us is worth our very best investment in you.

I look forward to meeting you in person. And, feel free to ask any and all questions you need answered and we’ll do our best to make your journey rewarding.

—Dr. Larry J. O’Neill, DMD, MAGD, ABGD

Many might joke about someone we know that “snores like a freight train” but its a serious issue. Snoring isn’t normal.


The truth is that snoring is a sign that, for a number of possible reasons, your respiratory system is not working well at night. That leads to a set of conditions known as sleep disordered breathing which often results in poor oxygen profusion during sleep. If your blood oxygen levels drop below 90 at night it has bad effects on your circulatory system, stressing your heart and the rest of your body, changing your blood chemistry and increasing your whole body inflammatory load. All this helps hasten all the problems of old age – type 2 diabetes, weight gain, high blood pressure and other heart problems, stroke, GERD, loss of libido, frequent trips to the bathroom at night, and daytime sleepiness including falling asleep at the wheel. Many relationships suffer because of the lack of sleep caused by the noise of snoring. Get your health and relationship back. Come let us evaluate your snoring with our state of the art and proprietary diagnostics.
