Bleeding gums at night are often linked to nighttime teeth grinding (bruxism) or gum disease. Let's explore these and other possibilities.
Common Causes of Nighttime Gum Bleeding:
-
Bruxism (Teeth Grinding): As noted in multiple sources, clenching or grinding your teeth at night puts consistent pressure on your gums, leading to soreness, inflammation, and bleeding. This is a very common cause. [1, 5, 7, 9]
-
Gum Disease (Gingivitis): Bleeding gums are a primary symptom of gingivitis, an early stage of gum disease. Plaque buildup irritates the gums, causing inflammation and bleeding, often noticed after brushing or flossing, but potentially also during sleep. [2, 6, 8, 10]
-
Other Less Common Causes: While less frequent, several other factors can contribute:
- Mouth Breathing: Sleeping with your mouth open can dry out your mouth, making your gums more susceptible to irritation and bleeding. [4]
- Certain Medical Conditions: Conditions like HIV infection, anemia, herpes, leukemia, and gum cancer can sometimes manifest as bleeding gums. [3]
- Poor Oral Hygiene: Insufficient brushing and flossing allow plaque to accumulate, leading to gingivitis and bleeding gums. [2, 7, 8]
- Irregular Blood Sugar: High blood sugar can increase the risk of gum problems and bleeding. [5]
- Stress: Stress can exacerbate gum issues and increase bleeding. [3]
What to Do:
If you experience persistent bleeding gums at night, consult a dentist. They can diagnose the underlying cause and recommend appropriate treatment, which may include:
- Improved Oral Hygiene: Thorough brushing and flossing are crucial for preventing plaque buildup.
- Mouthguard: A custom-fitted mouthguard can protect your teeth and gums from the damage caused by bruxism.
- Treatment for Gum Disease: Professional cleaning and possibly medication may be necessary to manage gingivitis or other gum diseases.
- Addressing Underlying Medical Conditions: If a medical condition is contributing, managing that condition is essential.
