What causes blisters on the tongue?

Under normal circumstances, tongue blisters may be associated with various factors such as poor oral hygiene, dietary irritation, oral ulcers, oral lichen planus, and herpetic stomatitis. It is recommended to seek medical attention promptly and receive treatments such as general care or medication under a doctor's guidance. Specific analyses are as follows:

1. Poor Oral Hygiene

Neglecting oral cleanliness can lead to food residue buildup and bacterial growth. Excessive bacterial proliferation may cause bad breath, tongue inflammation, and blistering. Daily maintenance of good oral hygiene is essential, including using mouthwash and regular professional teeth cleaning.

2. Dietary Irritation

Consuming excessively hot, spicy, or coarse foods and beverages can directly irritate the tongue surface due to high temperature, potentially leading to blister formation. It is advisable to reduce intake of irritating foods and rinse the mouth with mild salt water to alleviate discomfort.

3. Oral Ulcers

Oral ulcers are usually caused by abnormal immune function, vitamin deficiencies, or high levels of psychological stress. Damage to the oral mucosa can result in round or oval ulcers on the tongue, possibly causing blister-like appearances, severe pain, redness, and swelling around the ulcer. Patients should follow medical advice and use medications such as oral ulcer powder, Bingbor Powder, or Watermelon Frost for treatment.

4. Oral Lichen Planus

Oral lichen planus is typically caused by immune dysregulation, psychological stress, or endocrine abnormalities. Inflammation of the oral mucosa leads to white, net-like or linear lesions, which may present the aforementioned symptoms along with mild itching, pain, and dryness of the oral mucosa. Treatment under medical supervision may include Triamcinolone acetonide oral ointment, Cetylpyridinium Iodide tablets, or Tacrolimus ointment.

5. Herpetic Stomatitis

Herpetic stomatitis is primarily caused by infection with the herpes simplex virus. The virus spreads through direct contact or respiratory droplets, replicates within cells after infecting the oral mucosa, and causes cell lysis, resulting in blisters on the tongue. Additional symptoms may include pain, fever, and swollen lymph nodes. Patients should take medications such as Amoxicillin capsules, Roxithromycin capsules, or Levofloxacin Hydrochloride capsules as prescribed by a physician.

In daily life, it is important to improve lifestyle habits, maintain proper oral hygiene, rinse the mouth with concentrated saline after meals to reduce the growth of anaerobic bacteria in the oral cavity, and engage in regular physical exercise to enhance overall immunity.
