Small white spots on the inner corners of the mouth?


Hello Doctor: Recently, I have been experiencing inflammation in a sore inside my mouth.
I have been applying an oral ointment, but I noticed a row of small white spots near the corner of my mouth, close to the inflamed area.
I tried applying the oral ointment to these spots as well, but they have not disappeared.
The inflamed sore is almost healed, but the white spots remain and have slightly increased in number.
The spots are in a small row and have not spread.
When I touch them with my tongue, they feel a bit gritty.
This is the first time I have noticed this; it has not happened before.

If the mucosa or small salivary glands have not improved after two weeks, it is recommended to visit an otolaryngology clinic.
Wishing you good health.

Understanding white bumps inside the mouth can be a source of concern for many individuals. The presence of white spots or bumps can arise from various causes, and understanding these can help in determining the appropriate treatment.

Based on your description, it seems you are experiencing a combination of oral lesions, including a healing ulcer and the emergence of small white bumps near the corner of your mouth. These white spots could be attributed to several factors, including inflammation, infection, or other oral conditions.

1. Oral Candidiasis: One possible cause of white bumps in the mouth is oral thrush, a fungal infection caused by Candida species. This condition often presents as white patches or bumps that can be scraped off, revealing a red, inflamed surface underneath. It is more common in individuals with weakened immune systems, those who use inhaled corticosteroids, or those who have recently taken antibiotics.

2. Aphthous Ulcers: These are common and can appear as painful sores in the mouth, often surrounded by inflammation. They can sometimes be accompanied by white spots as the tissue heals. The presence of stress and lack of sleep, as you mentioned, can exacerbate the frequency and severity of these ulcers.

3. Oral Lichen Planus: This is a chronic inflammatory condition that can cause white patches or bumps in the mouth. It is often associated with a lacy white pattern and can be itchy or uncomfortable. The exact cause is unknown, but it is thought to be related to an immune response.

4. Leukoplakia: This condition presents as white patches in the mouth that cannot be scraped off. It can be caused by irritation, such as from tobacco use or ill-fitting dentures, and requires further evaluation to rule out precancerous changes.

5. Fibromas or Mucocele: These are benign growths that can appear as small bumps in the mouth. They are often painless and can develop due to irritation or trauma to the oral mucosa.

Given that you have already been using an oral ointment without significant improvement, it would be prudent to consult with a healthcare professional, such as a dentist or an ear, nose, and throat (ENT) specialist. They can perform a thorough examination and may recommend additional tests, such as a biopsy, if necessary, to determine the exact nature of the white bumps.

In the meantime, here are some general recommendations for managing oral lesions:
- Maintain Oral Hygiene: Regular brushing and flossing can help prevent further irritation and infection.

- Avoid Irritants: Stay away from spicy, acidic, or abrasive foods that may aggravate the lesions.

- Stay Hydrated: Drink plenty of water to keep the oral mucosa moist and promote healing.

- Manage Stress: Since stress can contribute to oral health issues, consider stress-reduction techniques such as mindfulness or relaxation exercises.

In conclusion, while the presence of white bumps in the mouth can be concerning, many causes are benign and treatable. A professional evaluation is essential to determine the underlying cause and appropriate treatment plan.
