Start Smiling!

Announcing a New Location and a New Look!

Why Did the Dentist Cross the Road?

To provide our patients with a NEW
State-of-the-Art Dental Office, of course!

The new year is bringing a few exciting changes for Dr. Sayeg’s office. We have called 180 Allen Road our home for over thirty years, so it was a surprise when we found out it had been sold to a developer. That developer will be tearing it down in order to build luxury one-bedroom apartments.

Luckily, a new building had been built right across from our parking lot with just enough space available to design a brand new office.

Our new location, 185 Allen Rd, is still conveniently located and has a ground floor entrance with free parking. Plus, we had the opportunity to redesign our office with even more comfort & privacy, while still providing the exceptional service you’ve always received. With new digital x-ray technology & nitrous oxide available in every room, satellite radio and streaming TV & movies, and less reliance on paper charts and records; you will have a state of the art dental experience!

How to find our new office:

The new office is located directly across from our previous office.

If you are turning onto Allen Road from Roswell Road – it is the third building on your left.

If you are coming from Sandy Springs Cr. or Lake Forrest Dr., it will be on your right just past HM Patterson’s Funeral Home.


Our Phone Number Remains the Same!

Start Smiling Makeover of the Month

John having broken a front crown decided it was time to fix his Smile. He had two old crowns on front teeth that were too large. Doing a combination of porcelain crowns and veneers we were able to give John the Smile he always wanted. Now no one needs to know he broke his front teeth as a child

Comments from Our Patients

My 3 1/2 year old was there for his second visit, and he remembered the staff, what
to do, and even wanted to go back to have his teeth tickled (cleaned) on his own.
The entire staff is absolutely amazing!

Pierson W


I appreciated the fact that I just stopped in without an appointment because of
a broken tooth and the staff quickly worked me in to see the Doc. That kind of accomodation
is somewhat rare these days.

Lee H


What can I say? Best dental office in the world!

Tim H


Lory was outgoing, friendly and professional, just like everyone at Dr. Sayeg’s office. I’m glad my girlfriend introduced me to the team. By far the best dental experience I have ever had.

Todd S


You’re as good as it gets.

Do You Snore? We can help!

If you snore loudly and often, you may be accustomed to middle of the night elbow thrusts and lots of bad jokes. But snoring is no laughing matter. That log-sawing noise that keeps everyone awake comes from efforts to force air through an airway that is not fully open.
An estimated 10% of adults snore. For most there are no serious medical consequences, but for some it is the first indication of a potentially life threatening disorder called “Obstructive Sleep Apnea”.
