Whole health dentistry that
alleviates your fears
boosts your confidencebrings out your best smile
Dentistry that treats the cause, not the symptom
At Lake Hill Dental, we're dedicated to making your experience clear, comfortable, and focused on long-term health.
We start by asking why you're here, then we take the time to explain what we're seeing and what your options are. Better yet, we show you: a microscope in every room means you can look at the bacteria in your own mouth right alongside us, so nothing gets lost in translation. Our care goes beyond basic cleanings, because gum disease is a bacterial problem, not a brushing problem, and treating the cause is what produces lasting results. With a focus on your overall well-being, we provide a calm, welcoming environment to ease any dental fears and help you feel confident in your care. Experience the Lake Hill Dental difference today.

It’s okay to feel nervous about the dentist
Caring for patients with dental anxiety is one of our core missions.

Our approach is simple.
We slow down and listen
Every visit begins with real conversation about your health history, concerns, risks, and goals so we can understand the full picture and treat the person, not just the teeth.
Show you what we see
Using photos, full-mouth imaging, and live microscopy, we make your health visible. When you can see your own biofilm, inflammation, or progress, you gain the clarity and confidence to take control.
Treat causes, not symptoms
Instead of reacting to problems, we focus on prevention, personalized therapy, and long-term wellness so your mouth—and your whole body—stay healthier for years to come.
Here’s how we treat the root cause
Comprehensive wellness exams
From detailed imaging to full medical history reviews, we evaluate your total health picture and create a personalized roadmap for prevention and long-term stability.
Advanced periodontal and biofilm therapy
We use microscopy, air polishing, laser therapy, and targeted care to reduce inflammation and support the oral–systemic connection.
Sedation for dental anxiety
With patience, nitrous oxide, and a gentle approach, we help even the most anxious patients finally feel safe in the dental chair.
What we see changes how we treat
Dr. Denning is a leader in the dental community, helping other dentists better understand and treat the disease processes that affect oral and overall health. In these conversations, he shares how his own shift toward health and longevity transformed the way he practices dentistry, from using microscopy and bacterial testing to helping patients understand inflammation, make informed decisions, and become active partners in their care.
