PDG has expanded their level of care by offering Periodontal services to the practice. Dr. Tassos Sfondouris, a Board Certified Periodontist is uniquely trained to provide care to patients. After he completed his periodontal specialty program, Dr. Sfondouris was selected to complete a Fellowship program in Prosthetics, where he focused on complex implant and restorative treatments. We are pleased to bring Dr. Sfondouris’ expertise to our patients in Bethesda, Potomac, Chevy Chase, and the entire Washington, DC area.


A Periodontist specializes in the prevention, diagnosis, and treatment of periodontal disease, and in the placement of dental implants. But their title does not do them justice. Periodontists are “Plastic Surgeons” of the mouth. They use creative and innovative surgical techniques to maximize surgical results to ultimately provide a more cosmetic result. They are experts in the treatment of oral inflammation. Dr. Sfondouris uses the latest techniques for diagnosing and treating periodontal disease, both non-surgically and surgically. His approach to treating periodontal disease is by educating patients about their disease, identifying patient’s individual risk factors and using the most minimally invasive and regenerative treatment protocols to manage the disease.  Futhermore, there is current research that states an association between Periodontal disease and other medical diseases. Because of this association, Dr. Sfondouris will partner with dentists and physicians to better understand and manage the patient.

A Periodontist will use his artistic skills to perform several procedures to improve the esthetics of your face and smile. These procedures are designed to correct:

  • Gummy smile or uneven gum line — If your teeth look too short and your smile is too gummy or your gums cover too much of some teeth while leaving the others the right length, crown lengthening might be the solution. During this procedure, excess gum tissue is removed to expose more of the crown of the tooth. Your gum line is then sculpted.
  • Long teeth/exposed roots — In some cases, receding gums cause the tooth root to become exposed, which makes your teeth look long and unsightly. Periodontal disease is sometimes the culprit behind long teeth and exposed roots. Soft tissue grafts and other root coverage procedures are designed to cover exposed roots, to reduce further gum recession and to protect vulnerable roots from decay.
  • Missing teeth — Dental implants are a more natural looking option compared to dentures or bridges because implants look and feel just like your own teeth. They also allow you to speak and eat with comfort and confidence. Implants involve placing an artificial root into your jaw, and after a healing period, an artificial tooth is attached to the root.
  • Indentations in the gums and jawbone — Tooth loss can cause an indentation in the gums and jawbone where the tooth used to be. This happens because the jawbone recedes when it no longer is holding a tooth in place. Not only is this indention unnatural looking, it also causes the replacement tooth to look too long compared to the adjacent teeth. Ridge augmentation can fill in this defect recapturing the natural contour of the gums and jaw.
