Home remedies are not substitutes for professional dental care. Tooth pain during pregnancy may indicate serious conditions requiring immediate professional attention. Always consult your dentist and OB/GYN before using any home remedies, especially during pregnancy. If you experience severe pain, swelling, fever, or signs of infection, seek immediate professional care.

Noticing a lump or swelling on your gums during pregnancy can be concerning, especially when it appears suddenly or you experience no pain. ​​While many oral changes during pregnancy are benign and related to hormonal fluctuations, some conditions require prompt professional evaluation. If you experience fever, severe swelling, difficulty swallowing, or signs of infection, seek immediate care.

Dental infections during pregnancy require professional attention, as oral health is closely connected to pregnancy outcomes. The good news is that with proper evaluation and care, most pregnancy-related gum growths can be effectively managed.

What Is a Pregnancy Tumor?

While the medical term includes the word “tumor,” this condition is a benign inflammatory growth, not cancer. Healthcare providers may also refer to it as a pregnancy epulis or pyogenic granuloma. The word “tumor” in this context simply means a localized growth or swelling.

Characteristics to consider include: 

  • Easy bleeding due to fragile, highly vascular tissue
  • Rapid growth during pregnancy-related hormonal changes
  • A bright red or swollen appearance 

 

A pregnancy-related gum growth may look more serious than it actually is. This type of growth is your body’s way of telling you that your gums need attention. 

Why Do Tumors Occur on Gums When You’re Pregnant?

The physical changes that occur in your body during pregnancy create a perfect environment for lumps to form. Your gums respond to bacteria in your mouth due to hormonal changes such as the increases in estrogen and progesterone, which:

  • Increase blood flow within the gum tissue
  • Alter the local immune response in the gums
  • Heighten inflammatory reactions to plaque and bacteria

 

Pregnancy hormones amplify your body’s reaction, while oral bacteria are the underlying trigger. This reaction leads to the formation of pregnancy tumors on the gums. This response reflects how pregnancy hormones can amplify inflammation in the gums, even in response to small amounts of plaque. Remaining plaque can lead to bacterial buildup, which eventually extends under the gumline. 

In most cases, this irritation remains localized and painless, although the growth may slowly increase beneath the gumline. When this area remains inflamed, it can lead to a bacterial overgrowth or a deeper infection, which means a visit to your dentist is needed. Even without pain, seeking medical attention should be high on your list, as your dental health affects your pregnancy

What Does a Pregnancy Tumor on the Gums Look Like?

A tumor may stand out due to its size and color, and may appear more dramatic than it feels. Visual changes to your gums are often the first sign that tissue is responding beneath the surface. These gum growths can vary in appearance

  • Red, dark pink, or purple, due to increased blood flow in the tissue
  • A smooth or lobed shape that may appear rounded or mushroom-like
  • A tendency to bleed when brushing, flossing, or eating firmer foods

 

Because the tissue is highly vascular, even minor contact can cause a lesion, resulting in bleeding. Stay calm, as bleeding does not always indicate a serious problem. Your dentist should evaluate the lump, even if it is small, as size alone does not determine whether you need further treatment. 

Are Pregnancy Tumors Dangerous?

The word “tumor” might seem frightening, as it’s often used to describe a cancerous lump, but in this instance, it refers to a lump on the gum. The correct term is benign inflammatory growth, as there’s no known risk of it spreading to other parts of your body or becoming cancerous. 

For pregnant women, the sight of a pregnancy tumor on the gums might be a bigger challenge than the lump itself. The tumor isn’t dangerous, but it can interfere with everyday dental health. For instance, brushing a bit too hard can cause the tumor to bleed. 

Cleaning between the gums can be challenging because the area may become sensitive. When you’re unable to clean your teeth, it can lead to plaque buildup. The growth may also affect how you eat and drink, which is another reason to visit your dentist. While dental tumors may be an irritation, your mouth is connected to your overall health.

When Should You See a Dentist?

Book an appointment with your dentist if you notice new or unusual changes in your mouth during pregnancy. Your dentist provides a professional evaluation to determine whether you need treatment. Consider seeing your dentist when you notice: 

  • Rapid growth or noticeable changes in the size or shape of a gum growth
  • Bleeding that occurs easily during gentle brushing, flossing, or eating
  • Pain, swelling, or persistent inflammation in the area
  • Discomfort while eating, drinking, or cleaning your teeth

 

Dental visits during pregnancy are safe and important for maintaining your oral health. If your dentist needs to have a closer look at what’s happening beneath the surface, there are pregnancy-safe digital imaging options available. Always inform your dentist that you’re pregnant to ensure you get the right clinical evaluation. 

Coordinating Dental Care During Pregnancy

Inform both your dentist and OB/GYN about any oral health concerns. Dental care during pregnancy is generally safe, though the timing of certain procedures may be optimized based on your trimester and individual circumstances. Your healthcare providers will work together to ensure both your oral health and pregnancy are supported.

How Dentists Address Pregnancy Tumors on the Gums

Treatment timing may be influenced by your trimester, with some procedures ideally performed during the second trimester when it’s safest. Your dentist will coordinate with your OB/GYN to determine the most appropriate timing for any necessary interventions.

The goal is to support your oral health while respecting the changes happening in your body during pregnancy. Ways dentists address gum lumps include: 

  • Monitoring the growth over time to assess changes
  • Recommending removal if the growth interferes with oral function or comfort
  • Addressing an underlying tooth issue if it is contributing to infection

 

Your health and the safety of your baby are your dentist’s top concerns, and in many cases, careful home care may be enough to manage symptoms.

Daily Oral Care Tips to Reduce Gum Irritation During Pregnancy

Consistent, thorough daily oral care helps reduce gum irritation and infection risk. Your dentist can provide personalized guidance on effective oral hygiene during pregnancy. 

Here’s what that looks like in practice:

  • Brush thoroughly, spending time on both your upper and lower teeth
  • Clean between your teeth daily using floss, interproximal brushes, or a water irrigator
  • Use a soft toothbrush if your gums feel tender or bleed easily
  • Use disclosing tablets if helpful to identify areas that need more attention

 

If you respond to visual feedback, consider using disclosing tablets to identify areas you might have missed. These tablets temporarily color plaque, making it easier for you to see and address. 

When to Seek Immediate Care

While most pregnancy-related gum growths are not emergencies, seek immediate professional care if you experience:

  • Fever or signs of systemic infection
  • Severe or rapidly increasing swelling
  • Difficulty swallowing or breathing
  • Severe pain that interferes with eating or sleeping
  • Pus or drainage from the affected area
  • Swelling that extends beyond the gum tissue

 

These symptoms may indicate a more serious condition requiring urgent attention.

What to Remember About Pregnancy Tumors on the Gums

Pregnancy tumors on the gums can look concerning, yet they are relatively common and usually benign. They often reflect how responsive the gums become during pregnancy, rather than being a serious problem in itself.

Think of these changes as a signal, not a diagnosis. They’re a reminder that your gums may need extra attention during a time of rapid change. It’s worth remembering that oral health is closely connected to whole-body health.
