Becosules Capsule may be helpful if your tongue ulcer is related to a deficiency of B vitamins, such as vitamin B12, but it is not a specific treatment for all tongue ulcers. Tongue sores can result from a variety of causes, including trauma, infections, irritation, nutritional deficiencies, or other medical conditions. Hence, a proper medical evaluation is important to identify the underlying cause. Most minor ulcers heal within 1 to 2 weeks with supportive care. In the meantime, you can ease discomfort by rinsing with salt water, maintaining good oral hygiene, and avoiding spicy or acidic foods. If the ulcer persists, recurs frequently, or is associated with severe pain, difficulty swallowing, or other concerning symptoms, seek medical attention for further assessment.
