Uneven Tongue Edges and White Spots: Dental Concerns Explained - Dentistry

Share to:

The edges of the tongue are uneven and have a white coating?


Hello, Doctor: Recently, I noticed that the edges of my tongue appear to have indentations from my teeth, making it uneven.
I am currently undergoing orthodontic treatment, and I have a missing tooth in the upper row.
I am wondering if the jagged appearance of the tongue's edge is due to pressure from my tongue against my teeth.
Additionally, I noticed that the edge near the tip of my tongue (next to the jagged area) seems to have a whitish appearance, which cannot be brushed off like tongue coating.
Upon closer inspection, it does not seem swollen or painful.
Are these symptoms related to lack of sleep or excessive heat in the body? I would appreciate your insights.
Thank you.

Hello, yes, that is indeed a dental imprint.
The reasons for this, aside from oral inflammation, can be related to habits such as clenching or grinding teeth.
When you clench or grind your teeth, you may need to swallow saliva, which causes your tongue to press against the sides of your teeth, resulting in imprints.
Wishing you peace and good health.
Sincerely, Dr.

The symptoms you are experiencing, such as the uneven edges of your tongue and the presence of white spots, can indeed be concerning, especially in the context of your ongoing orthodontic treatment. Based on your description, it seems that the unevenness of your tongue's edges may be due to the pressure exerted by your teeth, particularly if you have missing teeth or if your teeth are misaligned. This can lead to indentations or impressions on the sides of your tongue, giving it a serrated appearance.

The white spots you mentioned, which do not resemble typical oral thrush or canker sores, could be a result of several factors. One possibility is that they are areas of keratosis, which is a thickening of the skin or mucous membrane that can occur due to chronic irritation. In your case, the irritation could stem from the constant contact between your tongue and the edges of your teeth, especially if you are clenching or grinding your teeth, a condition known as bruxism. This can be exacerbated by stress, sleep deprivation, or even dietary factors, which may contribute to inflammation in the oral cavity.

Another potential cause for the white spots could be a condition known as geographic tongue, which is characterized by irregular patches on the surface of the tongue. These patches can appear white or red and may change location over time. While geographic tongue is generally harmless, it can sometimes be associated with discomfort or sensitivity.

Regarding your concerns about whether these symptoms could be related to lack of sleep or "heat" in traditional Chinese medicine (which often refers to inflammation or irritation), it is plausible. Sleep deprivation can weaken the immune system, making you more susceptible to oral health issues. Additionally, stress and poor sleep can lead to habits like teeth grinding, which can further irritate the tongue and oral mucosa.

To address your concerns, here are some recommendations:
1. Consult Your Orthodontist: Since you are undergoing orthodontic treatment, it is essential to discuss these symptoms with your orthodontist. They can assess whether your braces or any other dental appliances are contributing to the irritation and may suggest adjustments or protective measures.

2. Maintain Oral Hygiene: Ensure that you are practicing good oral hygiene. Brush your teeth at least twice a day and consider using a soft-bristled toothbrush to avoid further irritation. If you are using mouthwash, opt for an alcohol-free formula to prevent dryness and irritation.

3. Monitor Your Diet: Avoid spicy, acidic, or abrasive foods that may exacerbate irritation in your mouth. Staying hydrated can also help maintain the health of your oral mucosa.

4. Manage Stress: If you suspect that stress or sleep deprivation is contributing to your symptoms, consider incorporating stress-reducing techniques such as mindfulness, meditation, or gentle exercise into your routine.

5. Follow Up: If the white spots or the unevenness of your tongue persists or worsens, it is advisable to seek further evaluation from a dentist or an oral specialist. They can perform a thorough examination and may recommend treatments or interventions based on their findings.

In summary, while the symptoms you are experiencing may not indicate a severe underlying issue, they warrant attention, especially given your orthodontic treatment. By taking proactive steps and consulting with your dental care provider, you can address these concerns effectively and maintain your oral health.
