Periodontist (Gum Specialist)

Dr. Homan Hanasab (periodontist) graduated from UCLA with a bachelor degree in Psychobiology. He continued his education at USC School of Dentistry for his Doctorate of Dental Surgery. After practicing one year as a general practitioner, he continued his education at Boston University School of Dental Medicine to achieve his periodontal degree and Master of Science in Oral Biology.

Dr. Hanasab has been an active member of organized dentistry at the American Dental Association (ADA), the California Dental Association (CDA), American Academy of Periodontology (AAP) and San Fernando Valley Dental Society.

He is well trained in all aspect of periodontics and has a strong clinical background. He is proficient in all surgical modalities including but not limited to sinus lift (including using Piezo), block graft (Autogenous and Allograft), immediate and delayed dental implant placement (Biohorizon, Zimmer & 3i), crown lengthening, gingivectomy, ridge augmentation, soft/hard resective/regenerative procedures, and corticotomy for accelerated osteogenic orthodontics. He is also trained for Nitrous sedation.

Periodontology, or Periodontics, is the branch of dentistry which studies supporting structures of teeth, and diseases and conditions that affect them.
The supporting tissues are known as the periodontium, which includes the gingiva (gums), alveolar bone, cementum, and the periodontal ligament. The word comes from the Greek words peri meaning around and odons meaning tooth. Literally taken, it means study of that which is "around the tooth".
A Periodontist is a dentist who specializes in the prevention, diagnosis, and treatment of periodontal diseases, and the surgical placement and long term maintenance of dental implants.

Periodontal Disease

Periodontal diseases including gingivitis and periodontitis are caused by bacterial infections that destroy the attachment fibers and supporting bone that hold your teeth in your mouth. If they are left untreated, these diseases can lead to tooth loss.

There are many forms of periodontal disease:

  • Gingivitis
  • Aggressive periodontitis
  • Chronic periodontitis
  • Periodontitis as a manifestation of systemic diseases
  • Necrotizing periodontal diseases



Gingivitis is the mildest form of periodontal disease. Gingivitis is caused by plague build up (the sticky, colorless film that constantly forms on your teeth) around the teeth and gums. The plaque build up is often caused from inadequate oral hygiene. Other factors that may contribute to gingivitis include, diabetes, smoking, aging, genetic predisposition, systemic diseases and conditions, stress, inadequate nutrition, puberty, hormonal fluctuations, pregnancy, substance abuse, HIV infection, and certain medication use.

The bacteria in dental plaque irritate the gums and cause infection. When your body launches an immune response against these invaders, the gums become inflamed. The gums to become red, swollen, and bleed easily. People with gingivitis usually experience little or no discomfort.

The good news about gingivitis is that it is reversible with professional treatment and good home oral care. However, if gingivitis is left untreated, it can advance to periodontitis.


When gingivitis is untreated, it can lead to periodontitis. With time, plaque can spread and grow below the gum line. Toxins produced by the bacteria in plaque stimulate a chronic inflammatory response in which the body in essence turns on itself and the tissues and bone that support the teeth are broken down and destroyed. Pockets which are spaces between the teeth and gums deepen and become infected. As the disease progresses, the gum and bone are destroyed. Eventually teeth can become loose and may have to be removed.

There are many forms of periodontitis. The most common ones include the following:

  • Aggressive Periodontitis

  • Common features include rapid attachment loss and bone destruction and familial aggregation.

  • Chronic Periodontitis

  • This is the most frequently occurring form of periodontitis and is characterized by pocket formation and/or recession of the gums. It is prevalent in adults, but can occur at any age. Progression of attachment loss usually occurs slowly, but periods of rapid progression can occur.

  • Periodontitis as a Manifestation of Systemic Diseases

  • It often begins at a young age. Systemic conditions such as heart disease, respiratory disease, and diabetes are associated with this form of periodontitis.

  • Necrotizing Periodontal Disease

  • It is an infection characterized by necrosis of gingival tissues, periodontal ligament and alveolar bone. These lesions are most commonly observed in individuals with systemic conditions such as HIV infection, malnutrition and immunosuppression.
