Sublingual oral polyp

I have a growth under my tongue that I believe might be a normal polyp.
The images can be found here: https://imgur.com/gallery/L3AtDUc.
I've circled the area in question with a pen.
In the first image, the area circled in blue is where the polyp is located.
It seems that the polyp is not fully attached, as it appears to be growing from the area marked with the black pen.
Thank you!

More Info

Sublingual polyps, or any growths under the tongue, can be concerning, and it's important to understand their nature and implications. Polyps are generally benign growths that can occur in various parts of the body, including the oral cavity. They can be caused by a variety of factors, including irritation, chronic inflammation, or even genetic predispositions.
In the case of sublingual polyps, they may present as small, soft, and sometimes movable lumps under the tongue. They can vary in size and may be smooth or have a slightly irregular surface. While many sublingual polyps are harmless, it is crucial to have any new or changing growths evaluated by a healthcare professional, particularly an oral surgeon or an ENT specialist.
The appearance of a polyp under the tongue can be influenced by several factors, including:
1. Irritation or Trauma: Chronic irritation from dental appliances, rough teeth, or habitual biting can lead to the formation of polyps. If you have a habit of biting your tongue or if you have dental issues, this could be a contributing factor.

2. Inflammation: Conditions such as oral lichen planus or other inflammatory diseases can lead to the development of polyps or similar lesions in the mouth.

3. Cysts: Sometimes, what appears to be a polyp may actually be a mucous cyst (mucocele), which occurs when a salivary gland becomes blocked. These cysts are typically harmless and can resolve on their own, but they may require treatment if they cause discomfort or persist.

4. Infection: Certain infections can lead to the formation of growths in the oral cavity. If there is any associated pain, swelling, or discharge, it is essential to seek medical advice.

5. Neoplasms: While most sublingual polyps are benign, there is a small chance that they could be indicative of a more serious condition, such as a benign tumor or, in rare cases, malignancy.
Given your description and the images you provided, it is advisable to consult with a healthcare professional who can perform a thorough examination. They may recommend imaging studies or a biopsy to determine the exact nature of the growth.
In summary, while sublingual polyps can be normal and benign, it is essential to have them evaluated to rule out any serious conditions. Regular dental check-ups can also help monitor any changes in the oral cavity, ensuring that any potential issues are addressed promptly. If you notice any changes in size, color, or if you experience discomfort, do not hesitate to seek medical attention. Early diagnosis and management are key to maintaining oral health.
