Insurance Information
Our practice operates on a fee-for-service basis, meaning we are not in-network with dental insurance providers. Our team works with all PPO plans, although we're not contracted by them. We'll submit the claim on your behalf and help you maximize your benefits. Your insurance may reimburse you directly.
Our fee-for-service setup enables us to dedicate more time to our patients, utilize higher-quality materials, and recommend treatments based on what's best for your health—not what insurance dictates. We focus on quality, longevity, and comfort, and we'll review all costs before proceeding. You can always expect to feel informed, respected, and never taken by surprise. Financing through Cherry and CareCredit is available, as well as split-pay options for multi-step treatments. If you have any questions about our insurance and financial polices, please let us know. We're always here to help!

"Dr. Heiss was absolutely amazing! Since my dentist retired, I have been bouncing around from dentist to dentist. I don’t need to do that anymore! I found the one and only! I take pride in my teeth and smile. Dr. Heiss thoroughly explained everything about each tooth through his examination! The cleaning was one of the best I ever had! I already booked my six-month checkup and look forward to him being my forever dentist! Run to his office. He won’t disappoint!"
- Lisa S.
"My former dentist retired and I found out about Dentist Michael Heiss from my daughter’s dentist staff. I had my first appointment with him this week. The staff are very friendly and helpful. I do feel anxious when I go to the dentist and from the moment he came in the exam room Michael Heiss put me at ease. He explained everything he was doing and what to expect. I had a very positive experience and would recommend this practice to others!"
- Meredith R.
"I was greeted warmly by the entire staff, including Dr. Michael Heiss, Marie, and Tammy. Tammy took a comprehensive set of X-rays with ease. Dr. Heiss examined the x-rays and my teeth and fully and confidently explained what needed further treatment and the plan of action to get there. His calm and thorough manner put me at ease during an in-depth cleaning. Finally, home care instructions were given to prevent future dental issues. I fully recommend Long Island Dental Excellence as a place to receive a highly professional and caring dental experience."
