Our Philosophy. Going to the dentist should NOT be a scary experience.  At Aspen Hill Smiles we strive to make your visit as pleasant and comfortable as possible.  We start with a waiting room that looks like a living room, not like a doctor’s office.  Our kind and friendly staff will greet you and do everything possible to make your appointment easier and smoother. 


All your treatment options will be explained to you and accurate copay estimates will be given before any procedures are done. No billing surprises here. Payment plans are available as well. 


Watch TV on our wall and ceiling mounted monitors while we work. If you are extra nervous, we also offer sedation options.  After your appointment you will be given a hot lavender scented towel for your face and hands, before checking out with new-and-improved smile.  

Best-In-Class Technology. Aspen Hill Smiles offers some of the most advanced technology available in dentistry today.  Dr. Wyne is one of the few dentists in the country using 3D printing to improve quality of care. By using this advanced technology, we are able to provide clear aligners similar to Invisalign for a fraction of the price. 


Digital Panoramic x-rays mean a quick spin of our machine around the head gives us all the same information instantly. No painful bite wings needed! Intraoral cameras in each patient room allow us to show the patient high-resolution images of the inside of your mouth. If you're squeamish, you can skip that part. It's your choice.


We are high-tech and high-touch. We care about you, and making your dental experience exceptional.

Our talented hygienists not only make your teeth sparkle, they teach you how to keep them sparking and healthy until your next visit and beyond. 

Dental Emergencies


We are proud of the times we have come to the rescue of patients who were suffering excruciating pain or experienced a broken tooth right before an important event. We are here for you in your time of need!

Sedation Dentistry

Why feel anxious when you don't have to?

Relax. You're in good hands. 

Oral and Maxillofacial Surgery


When you need oral surgery, the care team at Aspen Hill Smiles is here for your every need. The advanced skills of our technical team mean most cases requiring dental surgery can be expertly treated in our own office. 


These clear aligners do an excellent job for our patients who suffer from misalignment problems. And they are nearly invisible too!



It's more than just straight teeth.

Orthodontics create confidence.



Healthy gums are vital to your oral health. Periodontal (gum) disease threatens the survival of your teeth as well as your overall health. By treating this disease as soon as it is detected, it can often be reversed. 



Watch out for sensitive teeth! We will work as a team to preserve every tooth that can be saved. Root canal therapy enables us to preserve a tooth that has suffered severe damage. 


We take great pride in providing our patients with natural-looking partial and complete dentures that offer comfort as well as functionality. 


It's time to bring back that beautiful smile! When a person's entire smile has suffered extensive damage, decay or loss, a beautiful smile is still achievable with full mouth reconstruction.

 "I love this dentist office so much. We're relatively new to the area and I had a horrible experience with another office. I'm thankful someone recommended Aspen Hill because it is easy to get to, there is plenty of parking and the staff is wonderful. The office is stylish, and they help you with your dental health without making you feel judged. Oh, and short wait times. I recommend them to anyone looking for an honest business. 10/10 would recommend."

"So glad to have finally found our forever dental practice! Growing up I had multiple bad experiences with dentists and didn't want my son to have the same fear of going. Dr. Wyne and his staff are welcoming, friendly, gentle and accommodating; I decided to get a mouth guard for sleeping and was able to be seen two days later. Highly recommend!"

“I went to the office for my regular cleaning with Hannah. The front office Jessica and Brittany answered all my questions, scheduled my next appointment. and even called my husband for me to tell him I was getting more work done . Thank you! The office was very welcoming, All the new safety procedures were explained to me and made me feel safe.  I ended up getting my teeth cleaned by Hannah, who is wonderful caring and just plain great! Dr. Wyne  had the time to replace my filling in the most painless manner. The staff is great which I feel is a reflection of his leadership.thanks for making my appointment, painless and safe"
