Dental Care During Pregnancy: What You Need to Know
Routine dental care — cleanings, fillings and shielded X-rays — is safe throughout pregnancy and is encouraged rather than postponed. Hormonal change commonly brings on pregnancy gingivitis, usually from the second trimester, causing red, swollen gums that bleed when brushing. Elective whitening and cosmetic work are better left until after delivery, and after vomiting you should rinse and wait 30 minutes before brushing softened enamel.

When you are expecting, dental care might not be the first thing on your mind — but it should be a priority. Hormonal changes during pregnancy can significantly affect your oral health, increasing the risk of gum inflammation, tooth decay, and other issues that can impact both you and your baby.
At Orion Dental in Scarborough and Milton, we routinely care for patients during pregnancy. This guide covers the most important things you need to know about keeping your teeth and gums healthy throughout all three trimesters.

Pregnancy Gingivitis: The Most Common Oral Health Change
Many pregnant people develop some degree of pregnancy gingivitis. This condition is caused by elevated levels of progesterone and oestrogen, which change the way gum tissue responds to the bacteria normally present in dental plaque. The result is inflammation, redness, swelling, and bleeding — particularly when brushing or flossing.
Pregnancy gingivitis typically appears during the second or third trimester and usually resolves after delivery, provided oral hygiene is maintained. However, if left untreated, it can progress to more serious gum disease.
Signs of Pregnancy Gingivitis
- Red, swollen, or tender gums
- Bleeding when brushing or flossing
- Increased sensitivity along the gum line
- Persistent bad breath
- A small, localised growth on the gums (pregnancy granuloma) — harmless but should be evaluated
Why Gum Health Matters During Pregnancy
Research has linked untreated periodontal disease during pregnancy to an increased risk of preterm birth and low birth weight, though study findings are mixed. The inflammatory response from a gum infection may trigger early labour. Keeping your gums healthy is an important part of prenatal care.
Morning Sickness and Your Teeth
Morning sickness is one of the most common pregnancy symptoms, and it can take a real toll on your teeth. Stomach acid is highly erosive — repeated exposure from vomiting can wear away enamel, leading to increased sensitivity, discolouration, and a higher risk of decay.
Your instinct after vomiting may be to brush your teeth immediately, but this is actually one of the worst things you can do. Acid softens the enamel surface, and brushing while it is soft accelerates erosion. Instead:
What to Do After Vomiting
Rinse Immediately
Rinse your mouth with plain water or a baking soda solution (1 tsp baking soda in 1 cup of water) to neutralise the acid.
Wait 30 Minutes
Give your saliva time to naturally remineralise the enamel surface before introducing any abrasion.
Brush Gently
After waiting, brush with a soft-bristle toothbrush and fluoride toothpaste using gentle, circular motions.
Which Dental Treatments Are Safe During Pregnancy?
Many expecting parents worry about the safety of dental treatment. The good news is that routine dental care is not only safe during pregnancy — it is recommended. Delaying necessary treatment can allow small problems to become larger ones.
| Treatment | Safety During Pregnancy | Notes |
|---|---|---|
| Dental cleanings | Safe — all trimesters | Recommended; helps manage pregnancy gingivitis |
| Fillings | Safe — all trimesters | Local anaesthesia (e.g., lidocaine) is safe |
| Dental X-rays | Safe with shielding | Lead apron and thyroid collar used; very low radiation |
| Root canals | Safe when needed | Should not be delayed — untreated infection is a greater risk |
| Tooth extractions | Safe when urgent | Second trimester preferred when possible |
| Teeth whitening | Postpone | Elective; best delayed until after delivery |
| Cosmetic procedures | Postpone | Non-urgent procedures should wait |

Oral Care Tips for Expecting Parents
Maintaining excellent oral hygiene during pregnancy does not require anything complicated — just consistency and a few targeted adjustments:
Schedule a Dental Visit Early
Ideally in the first trimester or early second trimester. Inform your dentist of your pregnancy and any medications you are taking.
Brush Twice Daily
Use a soft-bristle brush and fluoride toothpaste. If morning nausea makes brushing difficult, try a bland-tasting paste or brush later in the morning.
Floss Every Day
Hormonal changes make gums more susceptible to plaque. Daily flossing is more important than ever during pregnancy.
Manage Morning Sickness
Rinse with water or a baking soda solution after vomiting. Wait 30 minutes before brushing to protect softened enamel.
Eat a Balanced Diet
Foods rich in calcium, vitamins A, C, and D, and phosphorus support both your oral health and your baby's developing teeth and bones.
Stay Hydrated
Drinking plenty of water supports saliva production, which helps wash away bacteria and neutralise acids in your mouth.
Dental Care by Trimester
While dental care is safe throughout pregnancy, each trimester has its own considerations:
First Trimester
Inform dentist, routine care OK
Second Trimester
Ideal window for treatment
Third Trimester
Care safe; comfort position important
In the first trimester, schedule your dental visit and inform your dentist of your pregnancy. Routine cleanings and urgent care are safe. In the second trimester, this is the ideal time for any needed dental work — you are generally most comfortable, and the baby's critical development phase has passed. In the third trimester, dental care remains safe, but lying back in the dental chair for extended periods may become uncomfortable. Shorter appointments and position adjustments can help.
Don't Skip Your Dental Visits
The Canadian Dental Association encourages dental care during pregnancy. Routine checkups and cleanings are one of the best ways to prevent pregnancy gingivitis from progressing to more serious gum disease that may require periodontal therapy.

Frequently Asked Questions
Common questions about dental care during pregnancy
Is it safe to go to the dentist during pregnancy?
Yes. Routine dental care including cleanings, fillings, and X-rays (with appropriate shielding) is safe throughout pregnancy. In fact, dental care during pregnancy is encouraged to prevent complications. Elective cosmetic procedures are best postponed until after delivery.
What is pregnancy gingivitis?
Pregnancy gingivitis is gum inflammation caused by hormonal changes that alter the way your gums respond to bacteria. It typically appears in the second or third trimester and causes red, swollen, and bleeding gums. It is very common and treatable with professional cleaning and improved home care.
Can gum disease during pregnancy affect the baby?
Research has linked untreated gum disease during pregnancy to an increased risk of preterm birth and low birth weight, though study findings are mixed. The inflammatory response from a gum infection may contribute to early labour. Maintaining good oral health during pregnancy is important for both parent and child.
Are dental X-rays safe during pregnancy?
Modern dental X-rays use very low levels of radiation, and a lead apron with a thyroid collar provides additional protection. The Canadian Dental Association considers dental X-rays safe during pregnancy when clinically necessary.
How does morning sickness affect my teeth?
Frequent vomiting exposes teeth to strong stomach acid, which can erode enamel over time. After vomiting, rinse your mouth with water or a baking soda solution (one teaspoon in a glass of water) and wait 30 minutes before brushing to avoid damaging softened enamel.
When is the best time to schedule dental work during pregnancy?
The second trimester is generally considered the most comfortable time for dental treatment. However, urgent dental care should never be delayed regardless of the trimester. Routine cleanings can be scheduled at any point during pregnancy.
