White spots on the lips are usually caused by oil glands that sit close to the surface, known as Fordyce spots. They are generally painless, small, whitish or yellow bumps. They are not contagious and in most cases need no treatment.
Still, not every white spot on the lip is a Fordyce spot. If there is pain, burning, an open sore, crusting or growth, a cold sore, a canker sore, irritation or another oral lesion should be considered. Changes that persist or keep changing need to be assessed by a dentist.
What Are Fordyce Spots?
Fordyce spots occur when oil glands, which are normally linked to hair follicles, become visible in hairless areas such as the lips or the lining of the mouth. In medical sources they are also called Fordyce granules.
Although people call them spots, they are not a change in pigment. They are small gland structures that sit slightly raised above the surface. They can be seen on the edge of the lip, the inner lip and the cheek lining.
Fordyce spots are considered a normal anatomical variation. They are not a sign of infection, a sexually transmitted disease, poor oral care or cancer. In most people, the spots become more visible during adolescence and adulthood.
What Causes White Spots on the Lips?
There is no single answer to what causes white spots on the lips. Whether they are raised or flat, how long they have been there and any accompanying symptoms all matter when telling the causes apart.
Many small, similar-looking, painless spots can be consistent with Fordyce spots. A single white area that is wide or has an irregular surface may have a different cause.
Oil Glands Close to the Surface
The main cause of Fordyce spots is oil glands sitting close to the lip surface. The thin tissue of the lip can make the glands show through as white or yellow spots.
Dry and Irritated Lips
Cold weather, lip licking, cosmetic products, some toothpastes and oral care products can cause irritation. An irritated lip may become dry, flaky and cracked, with pale areas. This appearance is different from Fordyce spots.
Canker Sores and Cold Sores
A canker sore is a painful ulcer that usually forms on the inner side of the lip. Its center may be white or yellow with a red border. A cold sore, on the other hand, often starts with burning and tingling, followed by small fluid-filled blisters.
Oral Thrush
In oral thrush, creamy white layers can appear on the tongue, palate, cheek or inner lip. In some types the tissue underneath looks red when the layer is wiped away. A clinical examination is needed for a diagnosis.
Persistent White Patches
White areas that cannot be wiped off, keep thickening or develop a hardened surface may not look like Fordyce spots. Thickening from irritation, leukoplakia and other mucosal conditions are considered in the assessment.
How Can White Spots on the Lips Be Told Apart?
The features below can help compare the possible causes. Making a diagnosis by appearance alone is not appropriate.
| Possible Condition | Typical Appearance | Accompanying Findings | What to Do |
|---|---|---|---|
| Fordyce spots | Many small white or yellow bumps | Usually no pain, burning or ulceration | With a typical appearance, monitoring is often enough |
| Canker sore | An ulcer with a white or yellow center and red border | Pain and sensitivity while eating may occur | If it keeps returning or does not heal, an examination is needed |
| Cold sore | Clustered fluid-filled blisters and crusting | Tingling, burning or pain may occur | Since it can be contagious, close contact should be avoided |
| Oral thrush | Creamy white layers or patches | Burning, taste changes or redness may occur | A clinical assessment and treatment of the cause are needed |
| Irritation-related change | Dryness, flaking, cracks or a pale area | There may be a history of a new product or lip licking | Avoid the irritant; see a dentist if it does not settle |
| Leukoplakia or another white patch | A flat or thick white area that cannot be wiped off | It may be painless at first | If it persists, it should be assessed by a dentist |
Why Can White Spots Be More Obvious on the Upper Lip?
Fordyce spots can appear on both the lower and the upper lip. White spots on the upper lip may be clearer when the lip is stretched or looked at closely.
Having the spots on the upper lip is not on its own a sign of disease. In Fordyce spots the bumps are usually similar in size and arranged in clusters. They are expected not to change noticeably over weeks or months.
Painless spots that become visible when you stretch the lip can suggest Fordyce spots. Even so, if there is a sudden onset, one-sided growth or a surface change, an examination is appropriate.
What Are the Signs of Fordyce Spots?
Common features of Fordyce spots include:
- A white, cream, pale yellow or skin-colored appearance
- A small size, similar to a pinhead
- Occurring singly or in clusters
- Being found on the upper lip, lower lip, inner lip or cheek lining
- Becoming more obvious when the lip is stretched
- Usually causing no pain, burning, discharge or crusting
Painful, fluid-filled or quickly crusting lesions do not match the typical look of Fordyce spots. In that case other causes, such as cold sores and irritation, are assessed.
Are Fordyce Spots Contagious?
Fordyce spots are not contagious. They do not pass to another person through kissing, sharing a glass or skin contact. They are not caused by a virus, bacteria or fungus.
This feature separates Fordyce spots from cold sores. A cold sore can develop fluid-filled blisters after a burning sensation, and there is a risk of transmission while it is active. If you are unsure about the appearance, it is safer to limit close contact and get an examination.
How Are Fordyce Spots on the Lip Diagnosed?
The diagnosis is usually made by examining the mouth and lips. The dentist looks at the location, color, surface and distribution of the spots. You will be asked when they started and whether they have changed over time.
Pain, hardness, ulceration or a wide patch that cannot be wiped off can point to different causes. If needed, an assessment by dermatology, oral medicine or oral and maxillofacial surgery may be requested.
In typical Fordyce spots a biopsy is usually not needed. If the appearance differs from the usual features, or the diagnosis is unclear, further investigation can be planned.
One situation we see often at our clinic is patients mistaking painless spots that stand out when the lip is stretched for a cold sore. The time of onset, burning and blister formation help tell them apart.
How Do Fordyce Spots Go Away?
Since Fordyce spots are not a disease, treatment is not needed in most cases. The spots can stay the same for a long time. Scrubbing them with cleaning products or squeezing them does not remove these structures.
If the appearance clearly bothers you, the diagnosis needs to be confirmed first. The clinician assesses the location and extent of the spots, the lip tissue and the risk of scarring together.
Laser, electrocautery and similar procedures can be used in selected cases to reduce their appearance. However, the lip is a delicate area. Redness, crusting, color change or scarring can develop after a procedure. Results vary from person to person, and the spots may become visible again.
For that reason, if a procedure is being considered for cosmetic reasons alone, the benefits and possible risks should be discussed in detail. Acidic products sold online or over-the-counter chemical applications can burn the lip tissue.
What Can You Do at Home?
Home care does not remove Fordyce spots. It can, however, reduce lip dryness and irritation around the spots.
- Do not squeeze, prick or scratch the spots.
- Avoid constantly licking or biting your lips.
- Stop using perfumed or strongly flavored products if they irritate you.
- Use a plain moisturizer if the outer surface of the lip is dry.
- Protect your lips from the sun when you are outdoors for long periods.
- Change the product if irritation started after a new oral care item.
There is not enough scientific evidence that vinegar, lemon, garlic, baking soda or peeling products remove Fordyce spots. These substances can damage the protective layer of the lip.
When Should You See a Dentist?
Painless white spots on the lip that have been unchanged for a long time are usually not an emergency. Even so, you can be examined if you are not sure what they are.
Do not delay an assessment if you notice the following:
- A sore or white area lasting longer than two or three weeks
- A spot that grows quickly or becomes hard
- Bleeding on its own, crusting or an ulcer forming
- Pain, burning or numbness that does not go away
- A thick white or red-and-white patch that cannot be wiped off
- Difficulty swallowing, speaking or moving the jaw
- A lump you can feel on the lip, inside the mouth or in the neck
- A new lesion together with a condition that affects the immune system
Having these signs does not mean there is a serious disease. An examination separates common, harmless changes from lesions that need follow-up.
White Spots on the Lips: A Short Summary
Many small, painless white-yellow bumps on the lip can be consistent with Fordyce spots. They are oil glands close to the surface; they are not contagious and usually need no treatment.
A single wide spot, a painful sore, a fluid-filled blister or a patch that cannot be wiped off may point to a different cause. Rather than squeezing the spots, it is safer to watch for changes and see a dentist if anything looks suspicious.
Frequently Asked Questions
What causes small white spots on the lips?
Painless spots that occur in large numbers are usually Fordyce spots. Canker sores, cold sores, irritation and oral thrush can also cause a white appearance.
Are Fordyce spots contagious?
No. Fordyce spots are not an infection and do not spread through kissing, sharing items or skin contact.
Can Fordyce spots be squeezed out?
Squeezing does not remove them permanently. It can cause irritation, inflammation, color change or scarring on the lip.
Are white spots on the upper lip normal?
Painless spots of similar size that stand out when the lip is stretched may be Fordyce spots. Lesions that appear suddenly or change should be examined.
Do Fordyce spots go away on their own?
They can stay the same for a long time or become less noticeable over the years. Whether treatment is needed is decided by looking at the appearance and the person's expectations.
Is a white spot on the lip a sign of cancer?
Fordyce spots are benign structures. However, white areas that last longer than two or three weeks, harden, bleed or do not heal should be assessed by a dentist.
Which specialist should you see for white spots on the lip?
For a first assessment you can see a dentist or a dermatologist. If needed, an oral medicine or oral and maxillofacial surgery assessment is requested.
