Pregnancy Gingivitis: Causes, Care and When to See a Dentist
If your gums bleed when you brush or look puffy and red since you became pregnant, you are very likely dealing with pregnancy gingivitis. It is common, it is treatable, and a dental visit during pregnancy is safe. The sooner the plaque is cleaned away and your home routine is adjusted, the sooner your gums settle.
We see many expecting patients at our downtown Ottawa office. Most arrive worried about the blood in the sink. Most leave reassured, with a clear plan. This guide explains what is happening, what you can do at home, and when to call us.
We accept new patients, bill insurance directly, and accept CDCP and IFHP. If your gums are painful, swollen, or you cannot wait, contact us at mersaldental.ca and we will find you a same-day spot where we can.
TL;DR
Pregnancy gingivitis means red, swollen gums that bleed easily, caused by plaque bacteria plus hormone changes.
Brush twice a day for two minutes with a soft brush and fluoride toothpaste, and floss daily. Do not stop because your gums bleed.
Routine dental care, including cleanings, is considered safe during pregnancy. The first trimester is a good time to book a checkup and cleaning.
Gum disease develops slowly and often without pain, so do not wait for it to hurt before booking.
Pain, a spreading swelling, pus or fever need a dentist right away.

What pregnancy gingivitis is
Gingivitis is inflammation of the gums caused by bacteria along the gum line. During pregnancy, the Government of Canada explains that gums can become swollen, red or irritated, and the problem can show up anywhere between the third and ninth month. Rising estrogen and progesterone make the gum tissue more sensitive to the bacteria already in your mouth.
So pregnancy does not create gum disease out of nothing. It changes how your gums react to plaque. A small amount of plaque that your gums ignored before may now cause bleeding and puffiness.
The most common cause of gingivitis in anyone is plaque near the gums. If it is not removed, it can harden into tartar, which only an oral health professional can remove. That is why brushing alone sometimes is not enough, and why a professional cleaning matters.
Signs to look for
Healthy gums are firm and pale pink, and they do not bleed with normal brushing. Gingivitis usually shows up as:
Gums that are red or swollen
Blood on your toothbrush, floss or in the sink
Persistent bad breath
Tender gums, sometimes with discomfort when chewing
The first three match the symptoms of gingivitis listed by the Public Health Agency of Canada. Tenderness is also common in pregnancy, though it is not on every list.
Is bleeding normal?
Bleeding is common, but common does not mean you should ignore it. Your gums may bleed more easily during pregnancy because hormones make them more sensitive. Still, bleeding is a sign of inflammation, and inflammation is something we want to treat.
The usual reaction is to brush more gently or skip the sore area. That tends to backfire, because plaque stays where it is and the gums get worse. This article on bleeding gums in pregnancy explains why avoiding the area makes things worse.
Gingivitis or something more serious?
Gingivitis is the early, reversible stage of gum disease. If it is left alone, the infection can move deeper and affect the bone that holds your teeth. That later stage is called periodontitis.
The tricky part is that gum disease can be hard to recognize early because it develops slowly and without real pain. You may feel fine while your gums are inflamed. That is a good reason to have them checked rather than waiting for symptoms to get worse.
Call a dentist the same day if you notice:
Severe tooth or gum pain
Swelling of the face, jaw or gum that is growing
Pus, a bad taste that will not go away, or a bump on the gum
Fever together with any of the above
These can point to an infection rather than simple gingivitis. Our guides on tooth infection swelling and dental abscess symptoms describe what to watch for. We keep same-day emergency appointments for this reason.
Home care that helps
Good daily habits are the main treatment for mild pregnancy gingivitis. The Government of Canada’s advice is to brush twice a day for at least two minutes with a soft toothbrush and fluoride toothpaste, and to floss daily.
Here is how we suggest putting that into practice.
Brush gently, but do not skip areas
Use a soft brush. Angle the bristles toward the gum line and use small circles. Light pressure is enough. Press too hard and you can irritate sore gums further.
If an area bleeds, keep cleaning it gently. In most cases, bleeding eases within one to two weeks of consistent cleaning, though your own gums may take longer. If it does not ease, see us.
Floss every day
Flossing removes plaque between the teeth, where a brush cannot reach. Slide the floss in a C shape against each tooth. Expect some bleeding at first if you have not flossed regularly. If you find string floss hard on your hands or hard to manage, ask us about alternatives at your visit.
After morning sickness
Vomiting leaves stomach acid on your teeth. Brushing right away can scrub that acid into the enamel. The Government of Canada recommends that you rinse right away with water or a fluoride mouthwash, wait 30 minutes, and then brush.
Keep a small bottle of water or mouthwash where you are most likely to need it. If brushing makes you gag, try a smaller brush head, a milder toothpaste flavour, or brushing at a time of day when you feel steadier.
Water and snacks
It also helps to drink fluoridated water where it is available, which the Government of Canada recommends during pregnancy. The same guide suggests avoiding soft, sweet and sticky snacks, because they feed dental plaque.
Cravings are real. If you want a snack, choose something you can finish at one sitting rather than sipping or grazing all day. Rinse with water afterwards.
Dental cleaning while pregnant
This is the question we hear most. The answer is yes. Routine dental care, including cleanings, is considered safe during pregnancy according to the Canadian Dental Association, and it supports your health and your baby’s.
The Government of Canada suggests scheduling a checkup and cleaning in the first trimester. A cleaning removes the plaque and tartar that your gums are reacting to. For many patients with pregnancy gingivitis, this is the step that makes the biggest difference.
A cleaning is not only polishing. We remove buildup above and below the gum line, check for cavities and gum pockets, and show you how to clean the problem areas at home. You can read more about our hygiene appointments.
What to tell us
Tell us that you are pregnant and roughly how far along you are. Also tell us about any medications or prenatal vitamins, any nausea, and any medical conditions such as high blood pressure or gestational diabetes. The Canadian Dental Association notes that dentists can adjust medications, positioning and X-rays to protect you and your baby.
In late pregnancy, lying flat on your back can be uncomfortable. Tell us and we will change your position or give you breaks.
What about X-rays?
X-rays are only taken when they are needed, and they are not routine for every visit. If we do need one, it is adjusted for pregnancy. If you want background, see why dental X-rays are important, how often you really need them, and how dental X-ray doses compare in Canada. We always talk through this with you first.
Timing other dental work
If you need a filling or other treatment, the Government of Canada notes that the second trimester, between the fourth and sixth month, is the best time. Urgent problems such as infection or severe pain should not wait for a better trimester. Untreated infection is a bigger concern than treatment. We will plan what is safe with you and, if needed, your doctor or midwife.
If you have a lost or broken filling, see what to do when a filling falls out.
Perspective: what we tell expecting patients
Most patients with pregnancy gingivitis do not need complicated treatment. They need a thorough cleaning, a calm explanation, and a routine they can keep up when they are tired and nauseous.
We also see the same mistakes. Some patients stop flossing because it bleeds. Some postpone the dental visit until after the baby arrives. Some feel embarrassed about their gums. None of this is unusual, and none of it is a reason to feel guilty. Our job is to make the visit comfortable and efficient, and to treat pain quickly so you are not suffering through it.
Our team speaks several languages, so you can ask your questions in the language you are most comfortable with. Bring your partner or a family member if that helps.
If your gums are still bothering you after the baby is born, come in. The Government of Canada also advises contacting an oral health professional if pregnancy-related gum problems continue after childbirth. With a newborn, your own appointments are easy to push aside, so book it while you are thinking about it.

What treatment looks like at our office
Here is a typical visit for a patient with pregnancy gingivitis:
Conversation. We ask about your pregnancy, symptoms, health history and any worries.
Exam. We look at your gums, teeth and bite, and measure for gum pockets.
Cleaning. We remove plaque and tartar, including below the gum line when needed.
Home plan. We show you which areas need attention, and suggest a brush, floss or rinse that suits you.
Follow-up. If your gums are very inflamed, we may book a shorter check to see how they are healing.
If you have an abscess, a broken tooth, or a tooth that needs to come out, we can talk about extractions or root canal treatment and when each is appropriate. Cosmetic work such as whitening or Invisalign is usually better left until after pregnancy.
Paying for care in Ottawa
Cost should not be the reason you wait. We bill insurance directly, so if you have a private plan we can handle the claim paperwork for you. We also accept CDCP and IFHP.
The Canadian Dental Care Plan covers services such as exams, x-rays and cleaning, and also periodontal services such as cleaning under the gumline. Coverage depends on your eligibility and the plan’s rules, so confirm your own situation with the plan. Our page on CDCP and IFHP programs explains how it works at our office. Call us and we will help you check what applies.
Book a visit with us
We are a family dental office in downtown Ottawa. We accept new patients, offer same-day treatment and emergency care, and use modern technology to keep visits gentle and efficient.
If your gums are bleeding, swollen or tender, book a cleaning and gum check. If you are in pain, contact us for same-day emergency care. You can also read about same-day dental emergencies to know when it is time to call.
Preventing it next time
If you are planning another pregnancy, a dental visit beforehand puts you in a good position. Having cavities treated and tartar removed means your gums start from a healthier place.
During pregnancy:
Book a checkup and cleaning early.
Keep brushing and flossing, even when you are tired.
Rinse, wait, then brush after vomiting.
Limit sticky sweets.
Report any change in your gums rather than waiting for the next scheduled visit.
Gum disease is slow and quiet, so a regular schedule beats reacting to symptoms.
FAQ
When does pregnancy gingivitis start?
It can appear at any point between the third and ninth month of pregnancy, according to the Government of Canada. Some people notice bleeding earlier. If your gums change at any stage, mention it at your next visit or book one.
Will pregnancy gingivitis go away after birth?
For many people, the gums improve once hormone levels settle, especially with good plaque control. If the problem continues after childbirth, see an oral health professional. Do not assume it will fix itself, because plaque and tartar will still be there.
Is it safe to have my teeth cleaned while pregnant?
Yes. The Canadian Dental Association says routine care, including cleanings, is considered safe during pregnancy. Tell your dentist you are pregnant so positioning, medications and any X-rays can be adjusted.
How do I treat swollen gums at home?
Brush gently twice daily with a soft brush and fluoride toothpaste, floss daily, and drink fluoridated water where available. Rinse with water or fluoride mouthwash after vomiting, then wait 30 minutes before brushing. If swelling does not improve, or you have pain, pus or fever, see a dentist promptly.
