Introduction
Bleeding gums are mainly caused by dental calculus, periodontitis, gingivitis, etc. Treatment options—such as general management, medication, or surgical intervention—should be selected according to the specific cause. It is important to maintain good oral hygiene in daily life, and a soft-bristled, small-headed toothbrush is recommended. Avoid smoking and alcohol consumption, and refrain from consuming excessively hot, cold, acidic, or sweet irritating foods. Learn proper brushing techniques, brush teeth twice daily (morning and night), and rinse the mouth after meals.
Generally, the presence of blood clots during gum bleeding may be caused by improper brushing techniques, local oral irritation, gingivitis, periodontitis, or dental calculus. Symptomatic management may involve general care, medication, or surgical treatment as appropriate. If discomfort occurs, it is recommended to seek medical attention promptly and receive corresponding treatment under a doctor's guidance. Specific analyses are as follows:
1. Improper Brushing Technique
Brushing too hard or using a toothbrush with hard bristles can directly damage gum tissue. The gums contain abundant capillaries, and once injured, blood may leak out and coagulate in the mouth to form blood clots. It is recommended to learn proper brushing techniques, such as the Bass brushing method, and brush for at least three minutes each time.
2. Local Oral Irritation
During eating, food debris may become lodged between teeth or irritate the gumline. Sharp fragments, such as fish bones or nut shells, may lacerate the gums, causing bleeding that accumulates and forms clots. It is advisable to rinse the mouth with water or mouthwash after meals to remove food particles.
3. Gingivitis
Dental plaque is the primary cause of gingivitis. Inflammation mainly affects the free gingiva and interdental papillae, manifesting as gum bleeding and bad breath. When bleeding is significant, blood may coagulate in the mouth and form clots. Treatment under medical supervision may include medications such as minocycline hydrochloride capsules, tinidazole capsules, or ibuprofen sustained-release capsules.
4. Periodontitis
Periodontitis develops from untreated gingivitis. Under the combined effects of inflammation and tissue destruction, gums become more prone to bleeding. Due to more severe damage to periodontal tissues, bleeding may occur frequently and lead to clot formation. Follow your doctor’s instructions to use medications such as compound chlorhexidine mouthwash, amoxicillin granules, or cefaclor dispersible tablets to relieve symptoms.
5. Dental Calculus
Dental calculus forms when bacteria, food debris, and minerals from saliva accumulate on tooth surfaces over time and gradually mineralize into hard deposits. When calculus builds up around the gums, it causes redness, swelling, and softening of the gum tissue, making it fragile and prone to bleeding during brushing, which may result in blood clots. It is recommended to undergo professional treatments such as dental scaling or subgingival curettage under medical supervision.
Maintaining good oral hygiene is important. Choose a soft-bristled, small-headed toothbrush. Learn proper brushing techniques, brush twice daily (morning and night), rinse after meals, and develop the habit of using dental floss to clean between teeth.
