Pregnancy changes a lot of things, and your mouth is one of them. Many expecting parents are surprised when their gums start bleeding every time they brush, or a tooth that never bothered them suddenly feels sensitive. Most of these changes are common and manageable, but some are worth getting checked. At Highland Kitchener Dentist we see patients at every stage of pregnancy, and this post goes through the changes we hear about most, what’s behind them and what you can do about each one. If anything here sounds familiar, our Kitchener office is happy to take a look.
Why pregnancy affects your teeth and gums
The main driver is hormones. Higher levels of progesterone and estrogen increase blood flow to the gums and change how they react to plaque. The same small amount of plaque that caused no trouble before pregnancy can now lead to red, swollen, tender gums.
Other changes add to it. Morning sickness brings stomach acid into the mouth. Cravings and frequent small meals mean teeth are exposed to food more often. Some people find brushing their back teeth makes them gag, so they rush or skip it. And fatigue makes it easy to let the evening routine slide. None of this is anyone’s fault. It just helps to know what’s going on so you can adjust.
Changes you might notice
Bleeding, swollen gums
Often called pregnancy gingivitis, this is the most common oral change in pregnancy. It usually shows up in the second or third month and can last until after the baby is born. Signs include:
- Gums that bleed when you brush or floss
- Puffy, red or shiny gum tissue, especially between teeth
- Tenderness along the gumline
- Bad breath that doesn’t go away with brushing
It’s tempting to brush more gently or stop flossing when your gums bleed, but that usually makes it worse. Gentle, thorough cleaning is what calms the gums down. A professional cleaning during pregnancy can help a lot too.
Left untreated, gingivitis can progress to periodontitis, a deeper gum infection that affects the bone around the teeth. That’s one reason we like to see patients during pregnancy rather than waiting until after.
A lump on the gum
Some people develop a small, red, raw looking growth on the gum, usually between the teeth. It’s often called a pregnancy tumour, though it isn’t cancer and isn’t dangerous. It’s an overreaction of gum tissue to irritation, and it may bleed easily. Most shrink on their own after the baby is born. If one gets in the way of eating or brushing, or bleeds a lot, we can talk about options. Either way, any new lump in the mouth is worth showing to your dentist.
Sensitive or worn teeth
Repeated vomiting from morning sickness exposes teeth to stomach acid, which softens enamel. Over weeks or months this can cause sensitivity to cold and sweets, and in some cases visible wear on the inside surfaces of the teeth. Acid reflux, which is also common later in pregnancy, does the same.
More cavities
Frequent snacking, sugary cravings, sipping juice for nausea and less consistent brushing all raise the risk of decay. So does dry mouth, which some people get during pregnancy.
A dry or sticky mouth
Some people notice their mouth feels drier than usual, especially at night. Saliva is the mouth’s natural rinse. It washes away food and neutralizes acid, so when there’s less of it, cavities and bad breath become more likely. Sipping water often, chewing sugar free gum with xylitol and avoiding mouthwashes that contain alcohol can all help. If it’s bothering you, mention it at your next visit.
Loose feeling teeth
Pregnancy hormones affect the ligaments and bone that hold teeth in place. Some people notice teeth feel slightly loose. Usually this settles after pregnancy, but it can also be a sign of gum disease, so mention it at your visit.
Prevention tips that actually help
After morning sickness
- Rinse your mouth with water, or a teaspoon of baking soda in a cup of water, to neutralize the acid.
- Wait about 30 minutes before brushing. Brushing right away can scrub softened enamel.
- Use a fluoride toothpaste, and ask us whether a fluoride rinse would help you.
If brushing makes you gag
- Switch to a smaller headed brush
- Try a mild flavoured or unflavoured toothpaste
- Brush slowly, breathe through your nose and lean forward over the sink
- Brush at a time of day when nausea is lighter, often later in the morning
For your gums
- Brush twice a day along the gumline with a soft brush
- Floss or use interdental brushes once a day, even if there’s bleeding at first
- Keep up with your regular cleanings
For snacking and cravings
Eating more often is normal in pregnancy. To protect your teeth, lean toward snacks like cheese, yogurt, vegetables, nuts if you tolerate them and whole fruit. Drink water through the day and try to limit sipping sweet drinks over long periods. If you need something to settle nausea, plain crackers are easier on teeth than candy.
If you’re planning a pregnancy
If a baby is in your plans, a checkup beforehand is a smart move. It gives us a chance to treat any cavities or gum problems while you have the most flexibility, and to get your gums as healthy as possible before hormones start making them more reactive. It’s also a good time to have any older fillings or worrying teeth looked at, so you’re less likely to face a dental problem in the middle of pregnancy. Think of it as clearing the decks.
Is it safe to see the dentist while pregnant?
Yes. Checkups, cleanings and needed treatment are an important part of prenatal care. Tell us you’re pregnant and how far along you are, and let us know about any medications or advice from your doctor or midwife. Many people find the second trimester the most comfortable time for longer appointments. Urgent problems such as pain, swelling or infection shouldn’t wait at any stage.
If you’re feeling unwell on the day of an appointment, or lying back makes you dizzy or short of breath later in pregnancy, just tell us. We can adjust the chair, take breaks or rebook.
Your questions about oral health in pregnancy
Is it true you lose a tooth for every baby?
No. That’s an old saying, not a fact. With good care, pregnancy doesn’t have to cost you any teeth.
Will my gums go back to normal after the baby comes?
For most people, yes, once hormone levels settle. If bleeding or swelling continues after pregnancy, book a checkup so we can make sure nothing more is going on.
Does my oral health affect my baby?
Research has looked at links between gum disease and pregnancy outcomes, and keeping your gums healthy is a sensible part of looking after yourself. After birth, the bacteria that cause cavities can be passed to babies through shared spoons and cups, so a healthy mouth helps your little one too.
