Oral White Patches: When to See a Dentist or ENT - Dentistry

Oral issues


A month ago, I discovered a large white patch on the inner side of my right oral cavity.
I went to the hospital for an examination, and the doctor also palpated the area, but he said it was caused by frequently using the right side for eating.
However, I have a cavity on the left side, so I have been using the left side instead! The white patch has not disappeared yet.
Could this indicate some underlying condition? Should I see a dentist or an ear, nose, and throat specialist for further evaluation?

There is a whole patch of white on the inner side of the mouth.
It is important to check if the white surface feels rough or raised.
If you tend to chew food predominantly on one side, it may cause the oral mucosa on that side to be frequently irritated by the edges of the teeth, leading to inflammation.
It is recommended to consult a dentist for further evaluation and treatment.

More Info


When it comes to oral health, the presence of white patches in the mouth can be concerning and warrants careful consideration. In your case, you've noticed a persistent white patch on the inner side of your right cheek that has not resolved over the course of a month. While your previous examination by a healthcare professional suggested that this might be due to irritation from chewing, especially if you are favoring one side of your mouth, it is essential to explore this further, particularly since the patch has not improved.

White patches in the oral cavity can arise from various causes, including but not limited to:
1. Oral Lichen Planus: This is a chronic inflammatory condition that can present as white patches or lesions in the mouth. It may cause discomfort or pain and often requires monitoring and treatment.

2. Leukoplakia: This condition is characterized by white patches that cannot be scraped off. It can be benign but may also be precancerous, especially in individuals who smoke or use tobacco products.

3. Oral Candidiasis (Thrush): This fungal infection can lead to white patches that may be painful and can be scraped off, revealing a red, inflamed surface underneath.

4. Irritation or Trauma: As suggested by your previous doctor, if you are consistently chewing on one side of your mouth, it could lead to localized irritation, resulting in white patches due to inflammation.

5. Other Conditions: There are other potential causes, including autoimmune diseases, vitamin deficiencies, or even malignancies, which should not be overlooked.

Given that the white patch has persisted for over a month without improvement, it is advisable to seek further evaluation. Here are some steps you can take:
- Visit a Dentist: A dentist can perform a thorough examination of your oral cavity, possibly including a biopsy if necessary, to determine the exact nature of the white patch. They can also assess for any signs of oral cancer or other serious conditions.

- Consider an ENT Specialist: If your dentist finds no clear cause or if the condition persists despite treatment, an Ear, Nose, and Throat (ENT) specialist may provide additional insights, particularly if there are concerns about lesions that extend beyond the oral cavity.

- Monitor Symptoms: Keep track of any changes in the patch, such as size, color, or associated symptoms like pain or difficulty swallowing. This information can be helpful for your healthcare provider.

- Avoid Irritants: In the meantime, try to avoid any irritants, such as spicy or acidic foods, and maintain good oral hygiene to prevent further irritation.

In summary, while some white patches in the mouth can be benign and resolve on their own, the persistence of your symptoms suggests that further investigation is warranted. It is crucial to consult with a dental professional who can provide a definitive diagnosis and appropriate treatment plan. Early intervention can often lead to better outcomes, especially if there are underlying conditions that need to be addressed.
