Gum disease (gingivitis vs. periodontitis) explained

Healthy gums are the foundation of a healthy smile. But when plaque and bacteria build up around the gumline, it can lead to gum disease—a common condition that affects nearly half of adults over 30.
Left untreated, gum disease can damage your teeth, gums, and even your jawbone. In severe cases, it can lead to tooth loss.

In this blog, we’ll break down the two main stages of gum disease—gingivitis and periodontitis—including causes, symptoms, treatment options, and how to prevent it.

What Is Gum Disease?

Gum disease, also known as periodontal disease, is an infection of the tissues that surround and support your teeth. It starts off mild (gingivitis) but can progress into a more serious condition (periodontitis) if not treated early.

Stage 1: Gingivitis

Gingivitis is the earliest and mildest form of gum disease. It occurs when plaque—a sticky film of bacteria—builds up on the teeth and irritates the gum tissue.

Symptoms of Gingivitis:

  • Red or swollen gums

  • Bleeding when brushing or flossing

  • Bad breath (halitosis)

  • Mild gum tenderness

  • Receding gums (early sign)

The good news? Gingivitis is reversible with good oral hygiene and professional dental cleanings.

Stage 2: Periodontitis

If gingivitis is left untreated, it can progress to periodontitis—a more advanced form of gum disease where the infection spreads below the gumline, damaging the bone and connective tissue that hold teeth in place.

Symptoms of Periodontitis:

  • Persistent bad breath

  • Gum recession and pockets forming between teeth

  • Loose or shifting teeth

  • Pain when chewing

  • Tooth sensitivity due to exposed roots

  • Eventual tooth loss

Once gum disease reaches this stage, it is no longer reversible but can be managed with proper treatment and ongoing care.

What Causes Gum Disease?

The primary cause is plaque buildup from poor oral hygiene. However, several other factors can contribute to gum disease:

  • Smoking or tobacco use

  • Diabetes

  • Hormonal changes (e.g., pregnancy, menopause)

  • Medications that reduce saliva flow

  • Poor diet, especially one low in vitamin C

  • Genetics

  • Crooked teeth that are harder to clean

Treatment for Gum Disease

For Gingivitis:

  • Professional dental cleaning (scale and polish)

  • Improved brushing and flossing habits

  • Antibacterial mouth rinses

  • Regular dental check-ups

For Periodontitis:

  • Deep cleaning (scaling and root planing)

  • Antibiotic therapy (topical or oral)

  • Laser therapy (in some cases)

  • Gum surgery for advanced cases

  • Bone or tissue grafts if bone loss has occurred

How to Prevent Gum Disease

Prevention is the key to avoiding gum disease—and it starts at home:

  • Brush twice a day with fluoride toothpaste

  • Floss once a day

  • Use an antibacterial mouthwash

  • Visit your dentist every 6 months

  • Don’t smoke

  • Eat a balanced diet

Why Gum Health Matters Beyond Your Smile

Gum disease has been linked to serious systemic health issues, including:

  • Heart disease

  • Diabetes complications

  • Respiratory infections

  • Pregnancy complications (low birth weight or preterm birth)

  • Stroke

Taking care of your gums supports your overall health—not just your teeth.

When Should You See a Dentist?

If you notice bleeding gums, persistent bad breath, gum recession, or any pain or looseness in your teeth, don’t ignore it. Early intervention is the best way to stop gum disease in its tracks.

Conclusion: Protect Your Gums, Protect Your Smile

Gum disease can silently damage your oral health before you even feel symptoms. But with regular care, early detection, and the right treatment, you can maintain healthy gums for life.
