Why does my tooth bleed as soon as I suck on it?

Bleeding of the teeth upon suction is usually caused by multiple factors. The most common cause is gingivitis, which results from the long-term, chronic irritation of the gums by dental plaque and calculus. This leads to inflamed, swollen, and fragile gum tissue, making bleeding likely to occur during activities such as tooth brushing or suction. Dental calculus is also a significant contributing factor, as it sits at the gumline and continuously irritates the gums, making them prone to bleeding. In addition, localized oral conditions such as gingival polyps and periodontitis may also cause bleeding upon suction. Apart from local oral diseases, systemic conditions such as leukemia and coagulation disorders can also lead to gum bleeding. To relieve this symptom, one may try supplementing with vitamin C, using topical hemostatic agents, or undergoing treatments such as subgingival scaling and root planing. However, if symptoms persist or worsen, timely medical consultation is recommended to identify the underlying cause and receive targeted treatment. Maintaining good oral hygiene habits is also crucial for the prevention of gum bleeding.
