what is a dental spa?


Most people don’t associate dental treatment with spa services, but Smiles on Randolph is revolutionizing dentistry by combining comfort with the highest standard of dental care at our dental spa.

The American Dental Association recommends reducing stress at dental appointments to create a relaxing and luxurious experience, especially those with heart conditions and anxiety disorders. Just like a visit to a regular spa, personalizing your dental treatment to include spa-like services brings patients like you levels of relaxation and relief that you wouldn’t normally experience at a dental spa. 

When you arrive at our Smiles on Randolph dental spa, you are greeted with a smile and offered coffee and refreshments to help you feel at home. Our team pampers you with warm blankets, soothing music, sedation dentistry, and a separate relaxation room for when your treatment is completed, giving you a dental experience like you have never had before.

You’re welcomed walking in the door, offered refreshments, and they have an area for young children to entertain while waiting. Very clean office and polite staff. Dr. Sim is considerate while performing procedures and makes sure you’re good from beginning to end.

The staff is so great with children. My daughter loves going to have her baby teeth cleaned. My 6 year old is so excited to come back to get her 1st tooth pulled. I give that credit to the staff for making her experience so fun.

Top to bottom every single person in that office was in good spirits with a smile and all of them seemed like they were ready to help you out. I cannot imagine going to another dentist after that visit and I will make sure that the rest of my family and friends come as well.
