  • Periodontitis


    Periodontitis is an advanced form of gum disease. It can cause destruction of the supportive structures around your teeth and lead to permanent tooth loss.
    Untreated periodontitis can be serious and lead to complications such as:


    Bacteria grow on your teeth and create a filmy coating called plaque. A build up of this plaque causes an inflammation of the gum tissue, known as gingivitis. If gingivitis is left untreated, the plaque can extend under the gum line can create pockets around the teeth. Bacteria can collect in these pockets and cause regular inflammation and destruction known as periodontitis. Over time, this chronic inflammation and bacteria cause destruction of gum tissue, ligaments, and bones that hold your teeth in place.

    Risk Factors

    Poor oral hygiene including untreated gingivitis increases the risk of periodontitis.
    Other factors that can increase bacteria or plaque in your mouth include:
    • Genetics
    • Untreated gingivitis
    • Poor dietary habits
    • Advancing age
    • Uncontrolled diabetes
    • Suppressed immune system
    • Pregnancy
    • Smoking or chew tobacco


    Periodontitis normally occurs without symptoms. In those that have symptoms, periodontitis may cause:
    • Red, swollen, tender, or bleeding gums
    • Receding gums that may expose the root of your teeth
    • Loose teeth or teeth that fall out
    • Persistent bad breath
    • Presence of pus between your teeth
    • Change in the way your teeth fit together when you bite down
    • Swelling of face and jaw
    • Weight loss in elderly


    Your dentist will ask about your symptoms and medical history. A complete oral exam will be done. Periodontal disease can be diagnosed during an oral exam. Your dentist may do x-rays to determine how much damage has been done.


    The goal of treatment is to stop the bacterial invasion. Further course of treatment depends on the severity and progression of the periodontitis.
    Talk to your dentist about the best treatment plan for you. Options include:

    Deep Cleaning

    A cleaning procedure called scaling and root planing is done first. These will remove excess build-up above and below the gum line, and along the tooth root where bacteria thrive. In some cases, lasers can be used to remove plaque.


    Your dentist may recommend antibiotics to treat any bacterial infection. Antibiotics may be given as:
    • Oral tablets
    • Topical mouthwash
    • Beads that are placed into the infected gum pockets


    You may need surgery if your periodontitis doesn’t improve with deep cleaning or antibiotic treatment. Surgery may be also necessary to repair damaged gum tissues and bones. Surgical procedures include:
    • Flap surgery—Sections of gum tissue are opened to access the root of the tooth for deep cleaning. The gum tissue is reshaped and put back into position.
    • Bone and tissue graft—Tissue from another part of your body is used as a base to promote regrowth of healthy gum, bone, or connective tissue.
    • Enamel matrix application—A special gel is applied to the tooth root to stimulate growth of healthy bone and tissue.
    • Dental implants—An artificial tooth is placed in the jaw to hold a replacement tooth or bridge.


    To help reduce your chance of developing periodontitis, take these steps:
    • Brush your teeth and tongue at least two times per day with soft bristles to control plaque growth
    • Floss your teeth once per day
    • Use a mouthwash after brushing and flossing your teeth
    • If you smoke or chew tobacco, talk to your doctor or dentist about how you can quit successfully
    • See your dentist as recommended for regular cleanings and check-ups
