We are in Sunset Hills near I-44 and I-270. There is ample free parking next to our office. Easy walk-in access is available thru our west entrance for your convenience. Our office is Suite C-105 in the Courtyard level of the building.

We provide our patients with the first available appointment; many times in an emergency, same day service is offered to ensure that our patients receive immediate care to avoid undue discomfort.

After Hour Emergencies

We are available for after hour emergencies. If you recently received services in our office, please refer to your written post-surgical instructions for emergency information procedures.

If you are experiencing a dental emergency after hours that requires professional care, please contact Dr. Duello on his cell at 314-795-5557 or home at 314-822-0765.

If your are unable to contact Dr. Duello personally by phone, you may contact our office number listed to the right for additional emergency information or if another doctor is on call for Dr. Duello.

If this is considered to be a life-threating emergency, then call 911 for emergency EMT care or present to the nearest emergency room for care as soon as possible.
