Persistent white spots in the mouth can be concerning, and while they may not cause pain or discomfort, they can indicate a variety of conditions. It's important to understand that a definitive diagnosis can only be made through a physical examination by a healthcare professional, as many oral conditions can present similarly.

One common cause of white spots in the mouth is oral leukoplakia, which is characterized by white patches that cannot be scraped off. This condition is often associated with tobacco use, but it can also occur in non-smokers. While leukoplakia itself is not cancerous, it can be a precursor to oral cancer, especially if the patches are persistent. Therefore, it is crucial to have any persistent white lesions evaluated by a dentist or an oral specialist.

Another possibility is oral thrush, a fungal infection caused by an overgrowth of Candida yeast. This condition typically presents as creamy white patches on the tongue and inside the cheeks, which may be painful or cause a burning sensation. It is more common in individuals with weakened immune systems, those taking antibiotics, or individuals with diabetes.

Lichen planus is another condition that can cause white spots or streaks in the mouth. This inflammatory condition can affect the skin and mucous membranes, leading to a lace-like appearance in the oral cavity. It is often associated with stress and can be exacerbated by certain medications.

Fibromas or mucocele can also present as white or pale spots in the mouth. These are benign growths that can occur due to irritation or trauma to the oral mucosa. They are generally harmless but should be monitored for changes in size or appearance.

In some cases, white spots may be a result of oral herpes, particularly if there is a history of cold sores. While the initial outbreak is often painful, subsequent outbreaks may present with milder symptoms, including white spots or lesions.

Given your concern about the potential link to sexual activity, it is also important to consider sexually transmitted infections (STIs) such as human papillomavirus (HPV), which can cause oral warts or lesions. However, the presence of white spots alone does not confirm an STI, and testing is necessary for a proper diagnosis.

If the white spots have persisted without improvement, it is advisable to seek a consultation with a healthcare provider, preferably a dentist or an oral surgeon. They can perform a thorough examination, possibly including a biopsy if necessary, to determine the exact nature of the spots.
In summary, while persistent white spots in the mouth can be benign, they can also indicate more serious conditions. It is essential to have them evaluated by a professional to rule out any potential health issues and to receive appropriate treatment if needed. Regular dental check-ups and maintaining good oral hygiene are also important in preventing and identifying oral health issues early on.
