Tongue Issues: Causes of Teeth Marks and White Lines - Otolaryngology

When you notice teeth marks on your tongue along with white lines or spots, it can be concerning and may indicate several underlying issues. The presence of indentations or "teeth marks" on the tongue is often associated with a condition known as "lingua indentata." This condition occurs when the tongue is pressed against the teeth, which can happen due to various reasons, including bruxism (teeth grinding), an enlarged tongue (macroglossia), or simply due to the anatomical structure of your mouth.

The white lines or spots on the sides of your tongue could be a sign of several conditions. One common cause is irritation or inflammation of the mucous membranes in the mouth, which can occur due to habits such as biting the tongue or cheeks, or from the use of certain oral hygiene products that may contain alcohol or other irritating ingredients. If you have recently started using mouthwash, as mentioned in your previous queries, it could be contributing to the dryness or irritation you are experiencing.

Another possibility is that the white lines could be related to a condition known as leukoplakia, which is characterized by white patches on the mucous membranes. While leukoplakia can be benign, it is essential to monitor any changes, as it can sometimes be associated with more serious conditions, including precancerous lesions.
Additionally, the presence of spots or patches on the tongue could indicate oral thrush, a fungal infection caused by an overgrowth of Candida yeast. This condition is more common in individuals with weakened immune systems, those taking antibiotics, or those who have diabetes. Oral thrush typically presents as creamy white lesions that can be painful and may bleed if scraped.

If you are experiencing discomfort, persistent symptoms, or if the appearance of your tongue changes significantly, it is crucial to seek evaluation from a healthcare professional, such as a dentist or an ear, nose, and throat (ENT) specialist. They can perform a thorough examination, possibly including a biopsy if necessary, to determine the exact cause of your symptoms and recommend appropriate treatment.

In the meantime, here are some general recommendations to help manage your symptoms:
1. Maintain Good Oral Hygiene: Brush your teeth and tongue gently twice a day and floss regularly. Avoid harsh mouthwashes that contain alcohol, as they can further irritate the oral mucosa.

2. Stay Hydrated: Drink plenty of water to keep your mouth moist and help wash away food particles and bacteria.

3. Avoid Irritants: Steer clear of spicy, acidic, or abrasive foods that may exacerbate irritation in your mouth.

4. Monitor Your Habits: If you have a habit of biting your tongue or cheeks, try to be more mindful of it. Stress management techniques may help reduce bruxism if that is a contributing factor.

5. Consult a Professional: If symptoms persist or worsen, make an appointment with a dental or medical professional for a comprehensive evaluation.

In summary, while teeth marks and white lines on your tongue can be benign, they may also indicate underlying issues that require attention. Keeping track of any additional symptoms and seeking professional advice will be essential in addressing your concerns effectively.
