Oral White Spots: Causes and Concerns for Your Health - Dentistry

There are white spots on both the left and right sides of the oral cavity?


Hello, doctor.
In early July, I noticed two small white spots in my mouth, positioned symmetrically near the front.
They are not very noticeable, but when I lick them with my tongue, I can feel a raised sensation.
I visited an ENT clinic, and the doctor diagnosed it as oral ulcers and prescribed an oral ointment, but there was no improvement.
After a few days (during which I intentionally did not wear my removable dentures and brushed my teeth gently), the white spots became smaller (almost invisible), but I still feel discomfort when I lick them with my tongue.
Should I be concerned about the possibility of my dentures causing this issue (I've been wearing them for less than a year) or could it be oral cancer?

There are small white spots in the mouth with a raised sensation.
After applying an oral ointment, they did not disappear, but a few days later, after not wearing dentures and gently brushing, the white spots decreased in size.
This may be due to inflammation of the oral mucosa, which is gradually healing on its own.
It is recommended to consult a dentist for further evaluation and treatment.

Understanding oral white spots can be a source of concern for many individuals, especially when they appear unexpectedly and cause discomfort. Based on the symptoms you've described, it seems you have experienced white spots in your mouth that have persisted despite treatment. Let's delve into the possible causes and what you should consider regarding your health.

Oral white spots can arise from various conditions, and understanding these can help alleviate your concerns. Common causes include:
1. Oral Candidiasis (Thrush): This fungal infection is characterized by white patches in the mouth and can cause discomfort. It often occurs in individuals with weakened immune systems, those who use inhaled corticosteroids, or those who have recently taken antibiotics.

2. Oral Lichen Planus: This is a chronic inflammatory condition that can present as white patches or lesions in the mouth. It may cause pain or discomfort and is often associated with stress or other underlying health issues.

3. Leukoplakia: This condition involves thickened, white patches on the mucous membranes of the mouth. It can be caused by irritation from tobacco use, alcohol, or ill-fitting dentures. While leukoplakia itself is not cancerous, it can be a precursor to oral cancer, especially if the patches persist.

4. Aphthous Ulcers (Canker Sores): These painful sores can appear as white or yellowish spots with a red halo. They are often triggered by stress, hormonal changes, or certain food sensitivities.

5. Oral Cancer: While it is less common, persistent white spots or lesions in the mouth that do not heal can be a sign of oral cancer. Risk factors include tobacco use, heavy alcohol consumption, and HPV infection.

Given that you have already consulted an ENT specialist and received treatment without significant improvement, it is essential to consider a few steps moving forward:
- Follow-Up Consultation: If the white spots persist or worsen, it is crucial to return to your healthcare provider for further evaluation. A biopsy may be necessary to rule out more serious conditions, including oral cancer.

- Evaluate Denture Fit: Since you mentioned wearing dentures, it's important to ensure they fit properly. Ill-fitting dentures can cause irritation and lead to the development of lesions or sores in the mouth. If you suspect your dentures may be contributing to your symptoms, consult your dentist for an adjustment.

- Maintain Oral Hygiene: Good oral hygiene practices can help prevent infections and promote healing. This includes brushing your teeth and gums gently, using a soft-bristled toothbrush, and rinsing with an antiseptic mouthwash.

- Monitor Symptoms: Keep track of any changes in your symptoms, including the size, color, and sensation of the white spots. Note any new symptoms, such as pain, difficulty swallowing, or changes in taste.

- Manage Stress: Since stress can exacerbate oral conditions, consider incorporating stress-reduction techniques such as mindfulness, yoga, or regular exercise into your routine.

In conclusion, while the presence of white spots in the mouth can be alarming, many conditions are treatable and not necessarily indicative of a severe health issue. However, persistent symptoms warrant further investigation to ensure proper diagnosis and treatment. Always prioritize open communication with your healthcare providers and advocate for your health by seeking timely evaluations and interventions.
