Most people experience gum disease at some stage of their lives (Better Health Channel 2019a).

Ensuring that your clients maintain good oral hygiene and helping to provide oral care when required are crucial in preventing potentially irreversible damage.

What is Gum Disease?

Gum disease occurs when the gum (gingiva) - the mucosal tissue surrounding and protecting the teeth - becomes infected and inflamed (Wu & Oakley 2015; Healthdirect 2021).

What Causes Gum Disease?

gum disease plaque
Plaque is continuously being formed in the mouth.

Gum disease is usually caused by plaque, a sticky coating of bacteria that accumulates on the teeth along the gum line and causes irritation. The immune system triggers an inflammation response in order to remove this bacteria, leading to symptoms such as redness, swelling, tenderness and bleeding (Better Health Channel 2019a; QLD Health 2017).

All people naturally carry bacteria inside their mouths. These bacteria feed on the sugars in foods and drinks that are consumed. As a result, plaque is continuously being formed and providing millions of bacteria with an environment to live and multiply in (Better Health Channel 2019a; QLD Health 2017).

If plaque is not brushed off, it can harden into calculus (also known as tartar), which cannot be removed with a toothbrush alone (Healthdirect 2021).

In addition to poor oral hygiene, gum disease may also be caused by:

  • Systemic disorders, including diabetes and leukaemia
  • Exposure to heavy metals
  • Pellagra (vitamin B3 deficiency)
  • Scurvy (vitamin C deficiency)
  • Skin disease, including erosive lichen planus.

(Wu & Oakley 2015)

Risk Factors for Gum Disease

  • Smoking
  • Illicit drug use
  • Stress
  • Being immunocompromised
  • Viral or yeast infection
  • Xerostomia (dry mouth)
  • Taking certain medicines, including:
    • Antihistamines
    • Antihypertensives
    • Chemotherapy medicines
    • Immunosuppressive medications
    • Oral contraceptives
    • Bisphosphonates and monoclonal antibodies
  • Having a genetic predisposition
  • Poor nutrition
  • Poorly-fitting dental restoration
  • Pregnancy
  • Puberty.

Stages of Gum Disease

There are two main stages of gum disease:

  1. Gingivitis
  2. Periodontitis.

(Healthdirect 2021)

Gingivitis

gum disease gingivitis

Gingivitis is an early stage of gum disease that affects the superficial gum layers, particularly around the gum line. The deeper parts of the gum, teeth and bone are not yet affected (Better Health Channel 2019a).

Symptoms of gingivitis may include:

  • Puffy, swollen gums
  • Dusky red colouration of the gums
  • Gum tenderness
  • Gum bleeding
  • Bad breath.

(Wu & Oakley 2015)

Gingivitis is reversible. Treatment involves plaque removal, which should be performed as soon as possible in order to avoid complications and prevent disease progression (Healthdirect 2019).

About 22% of children (aged 5 to 14) and 29% of adults have gingivitis (AIHW 2021).

Periodontitis

gum disease periodontitis

Periodontitis is an irreversible, more serious stage of gum disease that occurs when gingivitis is left untreated (QLD Health 2017).

Periodontitis is an inflammation of the periodontium - the group of structures responsible for keeping the teeth in place. These structures include the cementum (tooth root covering), alveolar bone and periodontal ligament (fibres connecting the root of the tooth to the bone) (Better Health Channel 2019a; Katancik et al. 2016 pp. 189-202).

The periodontium is protected by the gum, which forms a seal around the neck of each tooth. However, if this seal is damaged by gum disease, periodontal pockets (spaces between the gum and the tooth roots) may form and trap bacteria. Gradually, the space between the gum and the tooth roots may increase and potentially lead to permanent bone loss (Better Health Channel 2019a).

If left untreated, this cumulative damage to the periodontium may become so severe that the teeth loosen and need to be removed (Better Health Channel 2019a).

Symptoms of periodontitis may include:

  • Gum swelling
  • Gum tenderness
  • Gum bleeding
  • Receding gums
  • Bright red or purplish colouration of the gums
  • Bad breath
  • Unpleasant taste in the mouth
  • Tenderness when biting
  • Loose teeth or movement of teeth
  • Newly formed spaces between teeth
  • Pus between the teeth and gums.

(Better Health Channel 2019a; Wu & Oakley 2015)

Periodontitis may cause the gums to recede.

Periodontitis is associated with complications such as:

  • Abscesses
  • Tooth loss
  • Increased risk of coronary artery disease, diabetes, respiratory conditions (e.g. asthma) and rheumatoid arthritis.

(Wu & Oakley 2015; Healthdirect 2019)

About 30% of adults over 14 years of age have periodontitis (AIHW 2021).

Treatment of Gum Disease

Gingivitis can be treated by removing plaque. Calculus will require removal by a dentist (Healthdirect 2019).

The patient should maintain an oral hygiene routine at home and visit the dentist regularly for monitoring (Wu & Oakley 2015).

Periodontitis may require additional treatment, including:

  • Root planning to remove accumulated plaque
  • Oral antibiotics
  • Flap surgery
  • Soft tissue graft
  • Bone graft
  • Guided tissue restoration.

(Wu & Oakley 2015)

It is crucial to seek treatment as soon as possible in order to prevent further damage (Better Health Channel 2019a).

Preventing Gum Disease

gum disease prevention

Strategies for preventing gum disease include:

  • Gently brushing the teeth and gum line twice daily using fluoride toothpaste, even if it causes bleeding
  • Using a toothbrush with a small head and soft bristles
  • Flossing daily
  • Visiting the dentist regularly
  • Appropriately caring for dentures
  • Avoiding smoking
  • Maintaining blood sugar levels (for people living with diabetes)
  • Avoiding consuming sugary foods and drinks, especially between meals
  • Drinking an adequate amount of water (ideally fluoridated).
