Sudden blood blisters under the tongue can be alarming, especially when they appear unexpectedly and grow rapidly. These blisters, also known as hematomas, can occur due to various reasons, including trauma, underlying medical conditions, or even certain medications. In your mother's case, since she does not have habits like smoking or chewing betel nut, we can explore other potential causes.

One common reason for blood blisters under the tongue is minor trauma. This could happen from accidentally biting the tongue while eating, which can lead to localized bleeding and the formation of a blister. Another possibility is that certain medical conditions, such as blood clotting disorders or thrombocytopenia (low platelet count), can make individuals more susceptible to bruising and hematoma formation. Additionally, some medications, particularly anticoagulants or blood thinners, can increase the risk of bleeding and bruising.

If your mother were to puncture or burst the blood blister, it could lead to several outcomes. First, it may cause pain and discomfort, as the area is sensitive. Second, it could lead to increased bleeding, as the blister contains pooled blood. This might also create a risk of infection if the area is not kept clean. Therefore, it is generally advisable to avoid popping blisters unless directed by a healthcare professional.

Regarding the appropriate medical specialist to consult, both an Ear, Nose, and Throat (ENT) doctor and a dentist can evaluate this condition. An ENT specialist is well-equipped to handle issues related to the oral cavity and can assess any underlying conditions that might be causing the blisters. On the other hand, a dentist can also provide insights, especially if the issue is related to dental health or oral hygiene. If the blisters persist or are accompanied by other symptoms, such as pain, swelling, or difficulty swallowing, it is essential to seek medical attention promptly.

In summary, sudden blood blisters under the tongue can arise from various causes, including trauma or underlying medical conditions. It is crucial to avoid puncturing the blister to prevent complications. Consulting with either an ENT specialist or a dentist would be appropriate to determine the underlying cause and receive appropriate care. If your mother experiences frequent occurrences of these blisters, further evaluation may be necessary to rule out any serious underlying conditions.
