Understanding oral blisters can be quite concerning, especially when they appear unexpectedly and cause discomfort. Based on your description, it seems you are experiencing recurrent oral blisters, which can be attributed to several factors.
Oral blisters, or vesicles, can arise from various causes, including viral infections, trauma, allergic reactions, or underlying health conditions. The most common viral cause is the herpes simplex virus, which can lead to cold sores or fever blisters. These typically appear on the lips or around the mouth and can recur, especially during times of stress or illness. However, since you mentioned that the blisters are located inside your mouth, they may also be related to other conditions such as aphthous ulcers (canker sores), which are not caused by a virus but can be triggered by stress, hormonal changes, certain foods, or nutritional deficiencies.

The fact that you experienced a blister that broke after brushing your teeth suggests that trauma may be a contributing factor. Oral hygiene practices, while essential, can sometimes inadvertently cause irritation or injury to the delicate mucosal tissues in the mouth, leading to the formation of blisters. Additionally, if you have a habit of grinding your teeth (bruxism), this could also contribute to the development of oral lesions due to constant friction.

As for the concern about the blisters multiplying, it is possible for new lesions to appear if the underlying cause persists. For instance, if the blisters are due to a viral infection, they may continue to recur until the virus is effectively managed. Similarly, if they are a result of trauma or irritation, avoiding those triggers will be crucial in preventing further outbreaks.

In terms of treatment, the approach will depend on the underlying cause of the blisters. If they are due to a viral infection, antiviral medications may be prescribed to help reduce the severity and duration of outbreaks. For aphthous ulcers, topical treatments such as corticosteroids or anesthetic gels can provide relief from pain and promote healing. Maintaining good oral hygiene is essential, but be gentle while brushing to avoid further irritation.

If the blisters persist, worsen, or are accompanied by other symptoms such as fever, difficulty swallowing, or significant pain, it is important to consult a healthcare professional for a thorough evaluation. They may recommend further diagnostic tests to rule out other conditions, such as autoimmune diseases or infections that could be contributing to your symptoms.

In summary, oral blisters can arise from various causes, including trauma, viral infections, or underlying health issues. Identifying the specific cause is key to effective treatment and prevention of recurrence. If you continue to experience these symptoms, seeking professional medical advice is crucial to ensure proper management and peace of mind.
