Seeing blood on your toothbrush can be alarming. But bleeding gums during pregnancy are very common, and most of the time they settle down with everyday care. Here's a step-by-step look at why it happens, how to brush, and when to see your dentist.
Why do gums get touchy during pregnancy?
Pregnancy brings big hormone changes. These changes make your gums swell easily and bleed at the slightest irritation. This is called pregnancy gingivitis. "Gingiva" means gums, so simply put, it's gum inflammation that happens during pregnancy.
What actually causes gum inflammation is plaque, the sticky film of bacteria that builds up on teeth. A small amount of plaque that normally wouldn't cause trouble makes the gums react much more strongly during pregnancy. So the gums turn red and puffy, and they bleed when you brush or floss.
It's so common that more than half of pregnant women experience it. It doesn't mean you've been caring for your teeth poorly, so there's no need to blame yourself or panic.
Here's a mistake many people make: brushing less to "give the gums a rest" because they bleed. That lets plaque build up, and the extra plaque makes the inflammation worse, so the gums bleed even more. It becomes a vicious cycle. On the other hand, the cleaner your teeth, the faster your gums settle down.
Sometimes one spot on the gum swells up like a red lump. Swollen gums from pregnancy usually get better after birth, but if a lump forms, it's a good idea to have your dentist take a look.
Even if your gums bleed, brush this way
The key is brushing gently and thoroughly, not hard.
- Choose a toothbrush with soft bristles. A hard brush can easily injure swollen gums.
- Put on fluoride toothpaste and rest the bristles lightly along the gumline, where teeth meet gums.
- With a light touch, move the brush in short, gentle strokes along the gumline. Brush both the outside and the inside.
- Don't skip the spots that bleed. Brush them more slowly instead. The more inflamed a spot is, the more the plaque needs to come off.
- Brush twice a day, and floss once a day, every day. A toothbrush can't reach between the teeth, so plaque builds up there easily.
If there's a lot of bleeding, rinse once with lukewarm water and then go back to brushing. If cold water makes your teeth sensitive, lukewarm water is more comfortable.
During pregnancy, you can tire easily, and brushing carefully for 2 minutes can feel like a lot. If so, split your mouth into four sections (upper, lower, left, and right) and spend 30 seconds on each. Setting an order helps you finish without missing anything.
If morning sickness makes you queasy as soon as the brush goes in, switch to a toothbrush with a smaller head, and it's fine to brush at a time of day when your stomach feels better. It doesn't have to be perfect every time. What matters is making time for one thorough brushing at least once a day.
Frequently asked questions
Is it really okay to keep brushing when my gums bleed?
Yes, it's okay. Bleeding is a sign that the gums are inflamed, and to calm the inflammation, the plaque needs to come off. Brushing gently and steadily with a soft toothbrush makes the bleeding fade over time.
Can I get a dental cleaning while pregnant?
Yes, cleanings and gum treatment are safe during pregnancy. Just let the dental office know how far along you are. When gum inflammation is severe, brushing at home alone may not be enough, so professional care can help a lot.
Will it get better on its own after the baby is born?
Swollen gums from pregnancy usually get better after birth. But if the bleeding continues or a gum lump doesn't go away, have your dentist check, even after birth.
If my gums hurt, is that bad for the baby?
A link between severe gum disease and preterm birth has been reported, but whether gum disease directly causes it hasn't been shown. Rather than worrying, the best thing you can do for yourself is to brush well and get any treatment you need.
