Welcome To Top Down Dental

At Top Down Dental, we strongly believe that a dentist should focus on oral-systemic health. Your mouth is the entrance to your body. By design, everything in the mouth has a pathway into your body. A healthy mouth establishes a firm foundation for your overall health, while disease in the mouth undermines your health from all sides.

A Holistic Approach To Dentistry

Oral health can affect whole-body health and vice versa. Our holistic approach to dentistry means that we treat your oral health in order to benefit your overall well-being. Our holistic approach involves a comprehensive look at your health by completing six different screenings including a health risk assessment, head and neck exam, airway health screening, occlusal screening, restorative screening, and periodontal screening. We also utilize minimally invasive treatments, mercury-free dental fillings, and restorations, and avoid toxic chemicals and compounds as much as necessary.

Yes! We regularly remove amalgam fillings and restorations and replace them with tooth-colored composite or ceramic fillings or restorations. Not only are these restorations natural-looking, durable, and healthy, but they reduce the risk of mercury exposure. We are a mercury-safe dental practice.
Although every procedure we offer uses a holistic approach, we do offer a few unique procedures you won’t find in your average dental office.

  • Ozone therapy is a safe procedure that neutralizes damaging acids in the mouth. It can reverse the decay process and occasionally help repair cavities without the need for dental fillings.
  • The DNA appliance is a holistic sleep apnea treatment that treats the underlying cause of the condition by establishing a healthy and attractive bite structure. The appliance reshapes the jaw to enlarge the airway.
  • NuCalm is a drug-free alternative to sedation dentistry that helps you stay relaxed during your procedure and feel refreshed afterward.

Fall in Love With Your Smile

When you look in the mirror, do you love the smile you see in your reflection? If not, Dr. Nehawandian can help you achieve your dream smile with a smile makeover. The smile makeover process involves a consultation first where you discuss the problem areas. Then, Dr. Nehawandian will suggest which treatments you need to achieve your goals and optimize your oral health. After you receive the necessary treatments, you will look in the mirror and feel more confident than ever.

It depends on each individual patient. Dr. Nehwandian creates a custom treatment plan for everyone. Your treatment plan depends on your specific needs.
A smile makeover can help you feel more confident, look younger, improve your social life, achieve better oral health, and ultimately change your life.

We Take Sanitation & Safety Seriously

As a holistic dental practice, we utilize the latest technology and techniques to ensure our patients have a completely safe and sanitary experience. We use high-speed suction equipment and a vacuum system to capture and filter saliva, droplets, and particles from dental procedures. Our medical-grade electrical air filters had already provided an extra layer of safety against airborne bacteria and viral particles. We also use Surgically Clean Air which is a medical-grade air filter that removes chemicals, toxins, germs, odors, and viruses.
