Tongue Indentations: Causes and Recovery Time - Dentistry

More Info

---

Understanding tongue indentations and associated symptoms can be quite complex, as they can arise from various causes and may indicate different underlying issues. Based on your description, it seems you have experienced a couple of distinct problems: the initial injury from dental floss and the subsequent pain in the left side of your tongue.


Causes of Tongue Indentations
1. Trauma from Dental Floss: The initial injury you sustained from dental floss can lead to localized trauma, which may cause indentations or ulcers. The red color and surrounding white spots you observed could be indicative of inflammation or a healing process. The white spots might be a sign of keratinization or a mild infection, but since you mentioned they have not spread and there is no pain, it is likely part of the normal healing process.

2. Oral Candidiasis: If the white spots were to spread or become more pronounced, it could suggest an oral yeast infection, commonly known as thrush. This condition often occurs in individuals with a compromised immune system or after antibiotic use.

3. Geographic Tongue: This benign condition can cause patches on the tongue that may appear red and inflamed, sometimes with white borders. It can cause discomfort but is generally harmless.

4. Other Causes: Other potential causes for indentations or changes in the tongue's appearance include vitamin deficiencies (such as B12 or folic acid), allergic reactions, or systemic conditions like lichen planus.


Recovery Time
The recovery time for tongue injuries can vary significantly based on the severity of the injury and individual healing rates. Generally, minor injuries like cuts or abrasions on the tongue can heal within a week or two. Since you mentioned that the indentation has not changed significantly over two weeks, it may take a bit longer for complete healing, especially if the tissue is still inflamed. If the indentation persists beyond a month or shows signs of worsening, it would be prudent to consult a healthcare professional for further evaluation.


Pain in the Left Side of the Tongue
The pain you are experiencing on the left side of your tongue when swallowing could be attributed to several factors:
1. Muscle Strain: If you have been favoring one side of your mouth due to the injury, it could lead to muscle strain or overuse, resulting in discomfort.

2. Nerve Irritation: The lingual nerve, which supplies sensation to the tongue, may be irritated due to the injury or inflammation, leading to localized pain.

3. Infection or Inflammation: If there is an underlying infection or inflammation in the throat or tongue, it could manifest as pain during swallowing.

4. Referred Pain: Sometimes, pain in the tongue can be referred from other areas, such as the throat or jaw, especially if there is tension or inflammation in those regions.


Recommendations
1. Maintain Oral Hygiene: Continue to practice good oral hygiene to prevent any secondary infections. Rinse your mouth with warm salt water to promote healing.

2. Avoid Irritants: Try to avoid spicy, acidic, or abrasive foods that could exacerbate the pain or irritation.

3. Monitor Symptoms: Keep an eye on the indentation and any changes in the pain. If the pain persists, worsens, or if you notice any new symptoms (like swelling, fever, or spreading of the white spots), seek medical attention.

4. Consult a Specialist: If the pain continues or if you have concerns about the healing process, consider consulting an oral surgeon or an ENT specialist for a thorough evaluation.

In summary, while minor tongue injuries typically heal well, persistent symptoms warrant further investigation to rule out any underlying conditions. Your health and comfort are paramount, so don’t hesitate to reach out for professional advice if needed.
