Short answer: Swollen and bleeding gums during pregnancy most often come from pregnancy gingivitis and are seen in more than half of pregnant women. Rising hormones increase the gum's reaction to bacterial plaque. It generally becomes more noticeable from the second month and recedes after birth. Regular brushing with a soft brush, cleaning between the teeth and, when needed, tartar cleaning, which can also be done during pregnancy, noticeably reduce the symptoms in most cases.
Seeing a pink trace in the sink when you brush, or noticing that your gums are redder and puffier than usual, is a common experience in pregnancy. Swollen gums during pregnancy and bleeding are often a sign of what is called "pregnancy gingivitis." Most sources report that some degree of gum inflammation is seen in more than half of pregnant women. In this article, we explain why it occurs, when it goes away, what a pregnancy granuloma is, and what can be done at home and at the clinic.
Why do gums swell and bleed during pregnancy?
The main reason for swollen and bleeding gums in pregnancy is that hormonal changes increase the gum's reaction to the bacterial plaque on the teeth. Estrogen and progesterone levels rise markedly in pregnancy. These hormones cause the small blood vessels in the gum to widen and become more permeable; the tissue holds more fluid, swells more easily and can bleed with light contact.
There is an important detail here: hormones alone do not cause inflammation; they amplify the reaction to plaque. In other words, as the layer of bacteria on the teeth decreases, the symptoms ease noticeably as well. In pregnancy, brushing becoming harder because of nausea, frequent snacks and dry mouth can make plaque buildup easier and worsen the picture. For more information about the general causes of gum bleeding, you can look at our article on what causes gum bleeding.
What symptoms are seen?
- Bleeding while brushing or flossing
- Redness, shininess and puffiness of the gums
- Sensitivity to touch, occasionally a mild ache
- Bad breath or a change in taste
- Swollen-looking gum triangles between the teeth
When does it start and when does it go away?
Pregnancy gingivitis generally begins around the second month, becomes more noticeable in the second and third trimesters and, in most cases, recedes in the weeks after birth as hormone levels return to normal. Many sources describe the period when symptoms are most intense as around the eighth month.
However, waiting for it to go away on its own after birth is not always right. Gum disease that was present before pregnancy can worsen during pregnancy and progress to deeper tissues, that is, to the bone and connective tissue that hold the tooth. This advanced picture is called periodontitis and does not resolve on its own after birth. In addition, some studies suggest there may be a link between advanced gum disease in pregnancy and preterm birth or low birth weight; whether this link is causal has not yet been established. Even so, it is seen as a sufficient reason to take care of gum health in pregnancy.
If you are planning a pregnancy
For women planning a pregnancy, having a dental check-up and, if needed, tartar cleaning before conceiving can help gum complaints be milder in the months ahead. Addressing existing cavities and gum problems in advance also reduces the likelihood of emergencies that could arise during pregnancy. This check-up is also a good opportunity to get oral care recommendations tailored to you.
What is a pregnancy granuloma (pregnancy tumor)?
A pregnancy granuloma is a benign, red-purple, easily bleeding soft tissue growth that develops on the gum. Although it is also called a "pregnancy tumor," it is not cancer; its medical name is pyogenic granuloma. It appears in a small proportion of pregnant women, mostly in the second trimester and usually on the upper jaw, in the gum area between two teeth.
A pregnancy granuloma generally shrinks after birth and often disappears on its own. For this reason, in most cases it is only monitored, and the plaque and tartar in the area are gently cleaned. If the granuloma grows large enough to make chewing difficult, bleeds often or prevents brushing, its removal by the dentist may be considered; it is also taken into account that it can recur if removed before birth. What a bump you have newly noticed on the gum is can only be decided with an exam; rather than trying to diagnose it yourself, the right step is to show it to your dentist.
What can be done at home?
The most effective thing that can be done at home is to remove plaque regularly and gently; stopping brushing because there is bleeding generally makes the picture worse. The following habits noticeably reduce the symptoms in most expectant mothers:
- Brush twice a day with a soft-bristled brush. Place the brush at a slight angle to the gum line and clean with small circular movements; do not press hard.
- Use fluoride toothpaste. If it triggers nausea, you can try a toothpaste with a milder flavor and a small-headed brush.
- Clean between the teeth every day. Floss or an interdental brush reaches the areas where plaque builds up the most. Light bleeding in the first days often decreases with regular cleaning.
- Do not brush right after vomiting. Rinse your mouth with water, or with a small amount of baking soda mixed into a glass of water, and wait about half an hour before brushing. This protects the enamel that acid has softened.
- Limit sugary snacks. Options such as cheese, yogurt and raw vegetables are both nutritious and more suitable for your teeth.
Those who want to use a mouth rinse should be sure to consult their dentist about the choice of product; some rinses contain alcohol or can cause staining with long-term use. For correct use, our article on how to use a gum mouth rinse can be a guide.
Can tartar cleaning be done during pregnancy?
Yes, tartar cleaning can be done during pregnancy and is often an important step in controlling pregnancy gingivitis. Tartar is hardened plaque and cannot be removed with a toothbrush; the bacteria that build up on it constantly feed gum inflammation. For this reason, a professional cleaning done at the clinic increases the effect of home care.
The most comfortable period for a planned cleaning is generally the second trimester (weeks 14–27). If symptoms are pronounced or bleeding affects daily life, a cleaning can also be considered in the first trimester. In some expectant mothers, more than one check-up and cleaning may be recommended during pregnancy. You can find how tartar cleaning is done and its effects on oral health in detail in our article on tartar cleaning. For general information about other dental treatments in pregnancy, you can look at our article on dental treatment during pregnancy.
The topic should be handled separately for those who become pregnant while using braces or clear aligners, or who are thinking of starting orthodontic treatment during pregnancy; the article on braces and clear aligners during pregnancy is a guide from this angle.
When should you see a dentist?
When you notice bleeding that does not stop with brushing, marked swelling, pain, a new bump on the gum, loosening of the teeth, or a bad taste and smell in the mouth, it is appropriate to plan an exam. Apart from these, even if symptoms are mild, having a dental check-up at the beginning of pregnancy is a good habit for catching possible problems early.
If you live in Ankara, your gum condition is evaluated at our polyclinic in Park Oran Ofis in Oran, Çankaya; the necessary cleaning and follow-up are planned according to your week of pregnancy and in harmony with your obstetrician. To make an appointment, you can use our contact page.
Frequently asked questions
Does gum bleeding in pregnancy harm the baby?
There is no finding that mild gum inflammation directly harms the baby. Although some studies suggest there may be a link between advanced gum disease and preterm birth, this link has not been established. Even so, protecting gum health during pregnancy and seeing a dentist if needed is recommended.
My gums bleed. Should I stop brushing?
No. The main cause of bleeding is plaque, and stopping brushing causes plaque to increase. Keep brushing gently with a soft-bristled brush and cleaning between the teeth; if the bleeding does not decrease within a few weeks, see your dentist.
Does a pregnancy granuloma go away after birth?
A pregnancy granuloma generally shrinks after birth and often disappears on its own. If it makes chewing difficult, bleeds often or does not disappear after birth, its removal by the dentist may be considered.
What can be done for gum pain during pregnancy?
Rinsing the mouth with warm salt water and gently cleaning the area often brings relief. If the pain is marked, comes with swelling or spreads to a tooth, an infection or a cavity may also be involved, so an exam is needed. Use any medication only on your doctor's recommendation.
