Pyogenic Granuloma (Pregnancy Tumor)
A pyogenic granuloma is a soft, red lump that pops up on the gums, usually between two teeth, and bleeds when you brush or floss. It can grow surprisingly fast over a few weeks, which understandably worries people. When it shows up during pregnancy, it's often called a pregnancy tumor. Despite the scary names, it isn't cancer, and it's very treatable.
A pyogenic granuloma is a harmless overgrowth of blood vessel-rich tissue, most often on the gums, triggered by irritation like plaque or by hormones. It's red, soft, bleeds easily, and can grow quickly. It's not cancer and not contagious. Pregnancy tumors often shrink after delivery. Have any new gum growth checked. Most are removed and biopsied, and cleaning away the irritant helps prevent regrowth.

What is a pyogenic granuloma?
A pyogenic granuloma is a benign overgrowth of tissue packed with tiny blood vessels. It forms when the gum (or skin) overreacts to ongoing irritation or to hormone changes, and keeps building new vessels instead of simply healing.
The name is misleading on both counts. "Pyogenic" means pus-forming, but it isn't an infection and doesn't contain pus. And "granuloma" is a specific type of inflammation that this isn't. The name dates to the early 1900s, when doctors thought these were caused by bacteria. Pathologists now often call it a lobular capillary hemangioma, which is more accurate: a cluster of small blood vessels arranged in lobules.
When one appears on the gums during pregnancy, it's called a pregnancy tumor or granuloma gravidarum. Under the microscope, it's the same lesion. "Tumor" here just means a swelling. It is not cancer.
What a pyogenic granuloma looks like
Most people notice blood on their toothbrush first, then find the bump. Typical features:
- Bright red to purplish. Newer ones are redder. Older ones can turn pinker and firmer as they scar.
- Soft and spongy, with a smooth or bumpy, lobulated surface. Sometimes the top is ulcerated with a yellowish film.
- Bleeds very easily, even with light brushing or eating.
- Often on a stalk, so it can wiggle, though some sit on a broad base.
- Grows fast, sometimes over just a few weeks, then usually levels off. Most stay under 2 cm.
- Usually painless, unless you bite on it.
Good clinical pyogenic granuloma pictures of the gums are hard to find, so the illustration below shows the classic look and where it tends to start.
Where pyogenic granulomas show up
In the mouth, the gums are by far the most common site, especially the gum between the upper front teeth on the cheek side. That's where plaque collects and where pregnancy gum inflammation tends to be worst.
They can also grow on the lips, tongue, inside of the cheek, and palate, often at a spot that gets bitten or rubbed. Outside the mouth, they're common on the skin, particularly fingers, hands, and the face, usually after a minor injury. Skin ones are treated by a dermatologist. This page focuses on the mouth.
A bump on the gums that bleeds can also show up around a dental implant or at the edge of a denture, wherever tissue is chronically irritated.
Pregnancy tumor on the gums
Pregnancy hormones make gum tissue react much more strongly to plaque. Most pregnant women notice puffy, bleeding gums (pregnancy gingivitis). In a smaller number, one spot overreacts and grows into a pregnancy tumor. Estimates range from well under 1% to about 5% of pregnancies, depending on the study.
- When it appears: usually in the first or second trimester, as hormone levels climb.
- How it behaves: it may keep growing through the pregnancy and is often largest in the third trimester.
- After delivery: many shrink noticeably once hormone levels drop. Some go away completely. Others shrink but leave a smaller, firmer bump that still needs removal.
- Is it harmful to the baby? No. It's a local gum problem. The main issues are bleeding, getting in the way of eating, and making it hard to keep the area clean.
Dental care during pregnancy is safe
The American College of Obstetricians and Gynecologists says dental care, including cleanings, needed x-rays, and local anesthetic, is safe during pregnancy. A professional cleaning is one of the most helpful things you can do for pregnancy gingivitis and for a pregnancy tumor, because it removes the plaque that feeds it. The second trimester is often the most comfortable time for non-urgent treatment, but you don't need to wait to get a cleaning or have a bleeding lump checked.
Should a pregnancy tumor be removed?
Many can be watched until after delivery, as long as you keep the area clean. Removal during pregnancy makes sense when it bleeds a lot, gets in the way of chewing, keeps getting bitten, or is growing quickly. Lesions removed during pregnancy are more likely to grow back, which is one reason many dentists prefer to wait when it's not causing problems. We coordinate with your OB when treatment is needed.
Pyogenic granuloma vs. other bumps on the gums
A red bump on the gums isn't always a pyogenic granuloma. Several common lesions look similar, which is why a biopsy is usually how we confirm what it is.
| Looks like | Key clues | Usual treatment | |
|---|---|---|---|
| Pyogenic granuloma | Bright red, soft, lumpy, often on a stalk | Bleeds very easily, grows fast, common in pregnancy and teens | Remove the irritant, then excision and biopsy |
| Gum boil (abscess, parulis) | Small yellow or red pimple-like bump near the root of a tooth | May drain pus or salty fluid. Often a dead or cracked tooth nearby. Can be tender. | Treat the tooth (root canal, gum treatment, or extraction) |
| Irritation fibroma | Smooth, firm, pink bump, often on the cheek or lip | Doesn't bleed easily, grows slowly, often at a bite line | Simple removal and biopsy |
| Peripheral giant cell granuloma | Red-purple or bluish gum bump | Only on the gums or a toothless ridge. Can affect the bone underneath, seen on x-ray. | Excision down to bone, biopsy |
| Peripheral ossifying fibroma | Firmer, pinker gum bump | Only on the gums. Slow growth. Can have calcified specks on x-ray. | Excision, biopsy, removal of local irritants |
| Hemangioma | Flat or raised red, blue, or purple spot | Often present since childhood. Blanches when pressed. Common on the lip or tongue. | Often just watched. Larger ones may be treated by a specialist. |
A few other things people mistake for a gum lump:
- Mucocele. A soft, bluish, fluid-filled bump, usually inside the lower lip, from a blocked saliva gland. See mucocele.
- Tori. Hard, bony bumps that are covered by normal pink tissue and don't bleed. See tori.
- Swollen gum around a tooth from trapped food (like a popcorn hull) or gum disease. It settles once the cause is cleaned out.
Is a pyogenic granuloma cancer?
No. A pyogenic granuloma is benign, and it doesn't turn into cancer. Its fast growth can be alarming, but that's just how this tissue behaves.
That said, a few uncommon conditions can look like a red, bleeding gum growth at first glance, including some cancers. That's why we don't rely on looks alone. When a lesion is removed, it's sent to a pathologist, and a biopsy is the only way to know for sure what it is. The vast majority come back as exactly what we expected. If you'd like to learn what to watch for in general, see our page on signs of oral cancer and our oral cancer screening page.
What causes a pyogenic granuloma?
It's a reaction, not an infection. Something irritates the tissue, and it responds by growing extra blood vessels. The common triggers:
- Plaque and tartar at the gumline. This is the most common one in the mouth.
- Local irritation: a rough or overhanging filling, a crown edge, a broken tooth, braces, a denture edge, or food that keeps getting packed in one spot.
- Injury: biting your cheek or lip, a toothbrush or floss injury, or a cut on the skin.
- Hormones: pregnancy most of all, and to a lesser degree puberty and hormonal birth control. This is why pyogenic granulomas are more common in women.
- Some medicines: a few drugs have been linked, including cyclosporine (used after organ transplants), and some acne and cancer medicines. Most of those reports involve the skin or nails.
Symptoms of a pyogenic granuloma
- A red or purplish bump on the gums or elsewhere in the mouth
- Bleeding when you brush, floss, or eat, sometimes more than you'd expect from such a small spot
- Growth over a few days to weeks
- Usually no pain, unless it's bitten or ulcerated
- Sometimes a feeling that something is "in the way" when chewing
Fever, a bad taste, or a pimple that drains points more toward a gum boil from an infected tooth. Numbness, a loose tooth with no clear reason, or an ulcer that won't heal are signs to get seen promptly.
How a pyogenic granuloma behaves over time
- Early: a small red bump that bleeds easily.
- Growth phase: it can enlarge quickly over a few weeks, then usually stops.
- Later: over months, it may become pinker and firmer as it matures and scars.
- On its own: outside of pregnancy, most don't fully go away by themselves. Pregnancy tumors are the exception and often shrink after delivery.
- After removal: most never come back. Regrowth happens in a minority of cases, especially if the irritant is still there or the lesion was removed during pregnancy.
Home care for a bump on the gums
There's no cream or rinse that makes a pyogenic granuloma disappear. Home care is about keeping it from getting bigger and keeping the bleeding under control until it's treated.
- Keep brushing the area. It's tempting to avoid a spot that bleeds, but plaque left behind feeds the lesion. Use a soft brush, angle it toward the gumline, and go gently over the bump itself.
- Clean between the teeth once a day. Floss or a small interdental brush. Expect some bleeding at first.
- Rinse with warm salt water (½ teaspoon in a cup of warm water) after meals if food tends to catch around it.
- Stop bleeding with pressure. Fold a piece of damp gauze or a clean cloth and press firmly on the spot for 10 to 15 minutes without peeking.
- Avoid biting or picking at it. Chew on the other side if it's in the way.
- Keep your cleaning appointments. Tartar has to be removed professionally. Brushing won't take it off.
Our home care instructions cover brushing and flossing technique in more detail.
What helps at home, and what doesn't
| Option | What it does | Things to know |
|---|---|---|
| Soft or electric toothbrush | Removes plaque without tearing the lesion | The single most useful thing you can do at home |
| Floss or interdental brushes | Cleans the gum between teeth where most of these start | Gentle, daily. Bleeding usually improves as inflammation settles. |
| Alcohol-free antiseptic or fluoride mouthwash | Helps reduce plaque bacteria | Doesn't shrink the lump. Alcohol-free stings less. |
| Pain relievers (acetaminophen, ibuprofen) | For soreness if it gets bitten | Usually not needed. In pregnancy, acetaminophen is generally preferred and NSAIDs are avoided unless your OB says otherwise. Follow the label for children's doses. |
| Numbing gels (benzocaine) | Brief relief if it's sore | Rarely needed. Do not use benzocaine in children under 2. |
| Avoid: cutting, tying off, burning, or skin-tag and wart removers | Nothing helpful | These cause heavy bleeding, burns, and infection, and they leave nothing to biopsy. |
Pyogenic granuloma treatment
Treatment has two parts: remove what's irritating the tissue, and remove the lesion so it can be examined.
- Exam and x-ray. We look at the lesion, check the teeth and fillings around it, and take an x-ray if needed to see whether the bone underneath is involved. That helps tell it apart from look-alikes like a peripheral giant cell granuloma. Our digital imaging keeps radiation low, and dental x-rays are considered safe in pregnancy.
- Professional cleaning. Removing plaque and tartar around the area is the first step. Small, early lesions, especially in pregnancy, sometimes shrink a lot after a good cleaning.
- Fix the irritant. Smooth or replace a rough filling, adjust a crown edge or denture, or address food packing between teeth.
- Surgical removal with biopsy. This is the standard treatment for a lesion that doesn't go away. The growth is removed down to its base under local anesthetic and sent to a pathologist. Depending on size and location, we may handle the biopsy here or refer you to a periodontist or oral surgeon who does these regularly. Some specialists use a laser to reduce bleeding.
- Follow-up. We check the area after it heals and keep an eye on it at your regular visits, since a small number grow back.
Removal is usually a quick procedure. The area is tender for a few days and heals in about 1 to 2 weeks. Some people need a small gum graft or reshaping later if the lesion left a gap between front teeth, but most don't.
If you're not sure what a growth is, our oral medicine and diagnosis visits are set up for exactly this kind of question.
How to prevent a pyogenic granuloma from coming back
- Keep plaque under control with daily brushing and cleaning between teeth.
- Get regular cleanings. If you're prone to gum inflammation, every 3 to 4 months may be better than twice a year. See our general and family dentistry page.
- Get rough edges fixed on fillings, crowns, and dentures.
- Plan ahead for pregnancy. A cleaning and check-up before or early in pregnancy reduces gum inflammation when hormones ramp up.
- Come in early if a new bump starts. Small ones are simpler to treat.
Kids, teens, and other groups
- Children and teens: pyogenic granulomas are common in teens and young adults, partly because of puberty hormones and partly because of braces, which trap plaque. Keeping the gums clean around brackets matters. A child with a growing gum lump should be seen, but this is usually a benign, treatable problem.
- Pregnancy: covered above. Cleanings and checkups are safe and encouraged.
- Denture wearers: a poorly fitting denture edge can trigger red, overgrown tissue. Adjusting or relining the denture is part of the fix. See dentures.
- Transplant patients and people on cyclosporine: gum overgrowth and pyogenic granulomas are more likely. We work with your medical team through our medically complex care program.
- People on blood thinners or with bleeding disorders: these lesions can bleed heavily. Let us know before any procedure so we can plan with your physician.
When to see a dentist about a bump on your gums
Make an appointment if:
- You have a new red or purple bump on your gums, lips, tongue, or cheek
- A bump bleeds when you brush or floss
- A lump has grown over a few weeks
- A pregnancy tumor is still there a few months after delivery
- A lump came back after it was removed
Get care quickly if:
- Bleeding won't stop after 15 to 20 minutes of firm pressure
- The lump is getting in the way of eating or you keep biting it
- You notice numbness, a loose tooth, or an ulcer that won't heal
- You have swelling, fever, or pus, which suggest an infection
Heavy bleeding that won't stop with pressure is urgent. Call us, and if you can't reach a dentist, see our emergency dental care page or go to urgent care.
Pyogenic granuloma FAQ
What is a pyogenic granuloma?
A pyogenic granuloma is a benign growth of tissue full of small blood vessels. It forms in response to irritation, like plaque or a rough filling, or to hormone changes such as pregnancy. In the mouth it's most common on the gums. Despite the name, it isn't an infection and it isn't a true granuloma.
Is a pyogenic granuloma cancerous?
No. A pyogenic granuloma is benign and doesn't turn into cancer. Because a few other conditions can look similar, the tissue is usually sent for a biopsy when it's removed. The biopsy confirms the diagnosis, and it almost always comes back as expected.
Will a pregnancy tumor go away after delivery?
Often, yes. Many pregnancy tumors shrink noticeably in the weeks after delivery as hormone levels fall, and some disappear completely. Others shrink but leave a smaller, firmer bump. If it's still there a few months after the baby is born, it should be removed and biopsied.
Is a pregnancy tumor dangerous for my baby?
No. A pregnancy tumor is a local gum growth and doesn't affect the baby. It can bleed and get in the way of eating, which is the main reason to treat it during pregnancy. Dental cleanings and needed dental care are safe during pregnancy.
Why does a pyogenic granuloma bleed so much?
A pyogenic granuloma is made mostly of tiny, fragile blood vessels close to the surface, with a thin covering of tissue. Even light brushing or chewing can break the surface. Firm pressure with damp gauze for 10 to 15 minutes usually stops the bleeding.
How is a pyogenic granuloma removed?
It's removed with a minor surgical procedure under local anesthetic. The lesion is cut away down to its base, the area is cleaned of plaque or tartar, and the tissue is sent for biopsy. A general dentist, periodontist, or oral surgeon may do it, and some use a laser to limit bleeding. Healing usually takes 1 to 2 weeks.
Can a pyogenic granuloma come back?
Yes, a minority grow back after removal. The risk is higher if the irritant that caused it is still there, if part of the base was left behind, or if it was removed during pregnancy. Good daily cleaning and regular professional cleanings lower the chance of regrowth.
Can a pyogenic granuloma go away on its own?
Pregnancy tumors often shrink after delivery, and small early lesions sometimes shrink after a professional cleaning. Outside of pregnancy, most pyogenic granuloma lesions don't fully go away on their own and need to be removed. Having it checked early makes treatment simpler.
What causes a red bump on my gums?
Common causes include a pyogenic granuloma, a gum boil from an infected tooth, swollen gum from trapped food, and other benign growths like a fibroma or giant cell granuloma. A bump that drains pus usually means infection. A soft red bump that bleeds easily and grew quickly is often a pyogenic granuloma. A dentist can tell you which it is.
Can I get a dental cleaning while pregnant?
Yes. Dental cleanings are safe at any point in pregnancy, and they're recommended. Pregnancy makes gums more reactive to plaque, so a cleaning can reduce bleeding and help keep a pregnancy tumor from growing. Let your dental office know how far along you are.
Can I remove a pyogenic granuloma at home?
No. Cutting, tying off, or burning a pyogenic granuloma at home can cause heavy bleeding and infection, and it often grows back because the base and the irritant are still there. It also leaves nothing for a biopsy. Removal is quick and straightforward in a dental office.
Does pyogenic granuloma removal hurt?
The area is numbed first, so you shouldn't feel pain during the procedure. Afterward it's usually tender for a few days. Most people manage with over-the-counter pain relievers as the label directs, salt-water rinses, and soft foods.
Found a bump on your gums?
If you're in the Jacksonville area and have a red, bleeding lump on your gums, pregnant or not, we're glad to take a look. We'll check what's irritating it, clean the area, and talk through whether it should be removed and biopsied.
