Overview
Gum disease, also known as periodontal disease, is an infection and inflammation of the tissues that support the teeth, including the gums, ligaments, and bone. It typically begins as gingivitis (mild gum inflammation) and can progress to periodontitis, where the bone and connective tissue are damaged. Gum disease develops gradually but can lead to tooth loss if not treated. It is one of the most common oral health issues worldwide and is strongly influenced by hygiene, lifestyle, and other health conditions.

Why It’s Important
Gum disease is a leading cause of tooth loss in adults, but its impact extends beyond the mouth. Research links it to serious health issues like heart disease, diabetes, and stroke, as bacteria and inflammation in the gums may affect the whole body. Because it progresses silently in many people, gum disease often goes unnoticed until it becomes severe. Recognizing the early signs can help prevent long-term oral and systemic health problems.

Quick Facts

• Affects nearly 50% of U.S. adults over age 30 in some form

• Risk increases with age, smoking, diabetes, and poor oral hygiene

• Can be mild (gingivitis) or severe (periodontitis)

• Considered a chronic condition if not properly managed

What Happens in the Body
Plaque, a sticky film of bacteria, builds up on teeth and gums. If not removed by brushing and flossing, it hardens into tartar, which irritates the gums and triggers an immune response. Over time, this leads to gum inflammation, tissue breakdown, and bone loss around teeth. In advanced cases, the gums pull away from the teeth, forming pockets where more bacteria grow, worsening the cycle.

Common Signs and Symptoms

• Red, swollen, or tender gums

• Bleeding during brushing or flossing

• Persistent bad breath or bad taste in the mouth

• Receding gums or teeth that appear longer

• Loose teeth or shifting bite

• Formation of deep pockets between teeth and gums

Diagnosis

• Dental exam to check for gum inflammation and pocket depth

• X-rays to assess bone loss

• Review of medical history and risk factors

• Regular dental cleanings help with early detection

Treatment and Management

• Gingivitis: Improved oral hygiene (brushing, flossing, mouth rinses) and professional dental cleaning can reverse early disease

• Periodontitis: Scaling and root planing (deep cleaning), antibiotics, and sometimes surgical treatments such as flap surgery or bone grafts

• Long-term management requires consistent oral care, regular dental visits, and control of contributing factors (like diabetes or smoking)

Risks and Complications

• Tooth loss

• Gum abscesses (infections)

• Bone loss in the jaw

• Links to systemic conditions such as diabetes, cardiovascular disease, respiratory illness, and pregnancy complications

Who Is at Risk

• Smokers and tobacco users

• People with diabetes or weakened immune systems

• Poor oral hygiene practices

• Hormonal changes (pregnancy, menopause)

• Genetic predisposition to gum disease

Related Conditions

• Diabetes (bidirectional relationship: gum disease worsens blood sugar control and vice versa)

• Cardiovascular disease

• Osteoporosis

• Respiratory infections (due to aspiration of oral bacteria)

When to See a Doctor/Dentist
See a dentist if you notice bleeding gums, persistent bad breath, gum recession, or loose teeth. Even if you have no symptoms, regular dental checkups are important since gum disease can progress silently. Urgent care is needed if you develop severe pain, swelling, or signs of abscess.
