The most common disease in which gums bleed frequently is gingivitis. Gingivitis is an inflammation of the entire periodontal gums due to the presence of large amounts of plaque and tartar from poor periodontal hygiene, resulting in the growth of a large number of bacteria, and the typical manifestation of gingivitis is red, swollen, brittle and bleeding gums. The most basic case of this bleeding is bleeding under stimulation, which commonly occurs when the patient brushes his teeth or bites hard food. Biting food is seen when the patient bites an apple or a pear and the blood stain stays on the corresponding fruit. Dental scaling treatment is recommended to remove plaque and calculus from the periodontium, thus relieving the bleeding gums.
