2026 Hong Kong Bleeding Tooth Alert: Why does gum bleeding when touched? Professor Loo Chan-min explains periodontal disease "help signals" in detail

If you accidentally cut your finger and it bleeds, most people will immediately disinfect and stop the bleeding; but what if it's bleeding gums? In 2026 in Hong Kong, bleeding gums remain a very common but often overlooked health problem. Dr. Lo Chin-man, Chair Professor of Public Health at the Faculty of Dentistry, University of Hong Kong, reminds everyone that bleeding gums are not a trivial matter; they are a symptom of gum inflammation and a distress signal from the body.

I. Shocking Data: 80% of Hong Kong Residents Are Ignoring the Crisis of Bleeding Teeth

According to oral health surveys, up to 80% of adults experience bleeding gums in half or more of their teeth. This is equivalent to more than half of your skin bleeding at the slightest touch, a truly alarming situation. However, most Hong Kong residents remain complacent:

• Extremely low rate of seeking medical help: Only 7% of people with bleeding gums seek dental help.

• Taking an avoidance attitude: Even if teeth become loose, 60% of people still do not take any action, and even mistakenly believe that drinking a cup of herbal tea to "clear heat" can solve the problem.

II. The root cause of bleeding gums: dental plaque and tartar

Gum becomes inflamed because it is attacked by bacteria. These bacteria mainly come from:

1. Dental plaque: soft deposits left behind when brushing teeth incompletely.

2. Tartar (Calculus): The product of long-term accumulation and hardening of dental plaque, which cannot be removed by brushing teeth.

These bacteria trigger the gums' defense mechanisms, causing them to become red, swollen, and prone to bleeding.

III. From Inflammation to Tooth Loss: The Terrifying Progression of Chronic Inflammation

If you ignore bleeding gums, plaque will continue to grow, triggering a serious "self-attack" response:

• Bone loss: Chronic inflammation can cause the gums and jawbone that protect teeth to slowly disappear.

• Irreversible damage: When you find that your gums are shrinking, your tooth roots are exposed, or even the gaps between your teeth are getting bigger and bigger and your teeth are loose, you have often missed the golden period for treatment.

IV. Recommendations for Periodontal Disease Prevention and Rescue Actions in 2026

Early detection and treatment are crucial. When you notice bleeding gums, you should take immediate action:

1. Seek professional teeth cleaning: Find a dentist to remove tartar and plaque, and remove the source of inflammation.

2. Learn the correct brushing technique, such as the "Bass Method," to ensure that the bristles reach deep into the gum line.

3. Use cleaning tools: Use interdental brushes, dental floss, or water flossers to make hidden plaque impossible to hide.

Part Three: FAQ (Frequently Asked Questions)

• Q1: If I get my teeth cleaned in Hong Kong in 2026, does more pain mean they are cleaner?

  • A: No. The soreness during teeth cleaning is usually related to the amount of tartar buildup and the degree of gum inflammation. If you bleed for a long time, you will bleed more easily during cleaning, but this is an essential process for clearing the lesions.

• Q2: Can mouthwash stop bleeding gums instead of brushing teeth?

  • A: Absolutely not. Mouthwash can only assist in removing physically attached tartar. Long-term reliance on mouthwash while neglecting brushing and professional dental cleanings will mask the underlying condition, causing periodontal disease to worsen.

• Q3: Is bleeding teeth really unrelated to “hot flushes”?

  • A: Professor Lu pointed out that bleeding gums are mainly caused by bacterial infection. Herbal tea may temporarily relieve oral discomfort, but it cannot remove tartar. If left untreated, the jawbone will continue to atrophy.
