Visible Blood Vessels Under the Tongue: What You Need to Know - Internal Medicine

Under the tongue


Hello, doctor.
I noticed two prominent black veins under my tongue after applying an oral ointment.
I would like to ask if it is normal to have such noticeable veins under the tongue? They don't hurt, so I'm wondering if it's something concerning.
Additionally, if I have a cut from biting my tongue, will rinsing with salt water help it heal faster besides using the oral ointment? My grandmother suggested I try that.

Hello, 1.
The blood vessels you see are the veins of the tongue, which is a normal phenomenon and the color is also normal, so there is no need to worry.
2.
The disinfecting effect of saline is not as effective as that of oral ointment and can be very irritating to the wound, so it is recommended to use oral ointment instead.
Thank you for your question.

More Info


Understanding visible blood vessels under the tongue can be a common concern for many individuals. The presence of prominent blood vessels, particularly the sublingual veins, is generally normal and can vary from person to person. These veins are responsible for draining blood from the tongue and are typically more visible in some individuals due to factors such as skin tone, hydration levels, and overall vascular health.

The sublingual area is rich in blood vessels, which is why you may notice these veins more prominently, especially if you are looking closely or if there is any swelling or irritation in the area. The color of these veins can sometimes appear darker, which is often due to the blood within them being deoxygenated. This is a normal anatomical feature and usually does not indicate any underlying health issues, especially if there is no pain or discomfort associated with it.

If you are experiencing a sore or a cut in your mouth, such as from accidentally biting your tongue, applying an oral ointment can help soothe the area. However, it's important to note that while saltwater rinses are often recommended for their antiseptic properties, they can also be irritating to open wounds. Saltwater can help reduce inflammation and promote healing, but it should be used cautiously. If you choose to use a saltwater rinse, make sure to dilute it properly (typically one teaspoon of salt in a cup of warm water) to avoid excessive irritation.

In addition to saltwater rinses, maintaining good oral hygiene is crucial for healing. This includes brushing your teeth gently and avoiding spicy or acidic foods that may aggravate the sore. Staying hydrated and avoiding tobacco products can also support the healing process.

If the prominent veins or any sores in your mouth persist, change in color, or are accompanied by other symptoms such as pain, swelling, or difficulty swallowing, it would be wise to consult a healthcare professional. They can provide a thorough examination and determine if any further action is necessary.

In summary, visible blood vessels under the tongue are generally normal and not a cause for concern unless accompanied by other symptoms. For minor oral injuries, saltwater rinses can be beneficial, but they should be used with caution. Always prioritize good oral hygiene and consult a healthcare provider if you have any ongoing concerns.
