Can pregnancy change your gums?
Yes. Hormone changes during pregnancy can make gums more reactive to plaque along the gumline. Better Health Channel explains that pregnancy hormones can put some women at risk of gum problems such as gingivitis, with swelling and bleeding mostly when brushing or cleaning between the teeth (Better Health Channel). The Australian Dental Association and Queensland Health likewise note that hormones can make gums more sensitive to bacteria or plaque in the mouth (teeth.org.au; Queensland Health).
Gingivitis is inflammation of the gum, often linked to plaque. Bleeding when you brush does not always mean advanced gum disease, but it is still worth having checked. Pregnancy does not by itself permanently damage teeth — the old saying about losing a tooth for every baby is a myth (teeth.org.au) — yet vomiting, diet changes and gum reactivity can raise the chance of problems if home care slips.

How should you look after your teeth day to day?
Keep brushing twice a day with fluoride toothpaste and clean between your teeth at least once a day. Healthdirect advises brushing twice daily with a soft toothbrush and fluoride toothpaste, and cleaning between the teeth daily (healthdirect). Better Health Channel and Queensland Health give the same core message for pregnancy (Better Health Channel; Queensland Health).
Spit out toothpaste after brushing; you do not need to rinse with water afterwards so fluoride can stay on the teeth. If gums bleed, continue careful cleaning rather than stopping. See bleeding gums: when to see a dentist.
Food cravings for sugary snacks are common. Better Health Channel and the ADA suggest choosing lower-sugar snacks where you can, and rinsing with water after a sweet treat (Better Health Channel; teeth.org.au). NSW Health also highlights daily hygiene and dental visits before, during and after pregnancy (NSW Health).
What should you do after vomiting or reflux?
Rinse your mouth with water, then wait before you brush. Vomiting and reflux bring stomach acid into contact with the teeth. Dental erosion is wear of tooth enamel when acid softens it and the softened surface is then worn away (healthdirect).
Healthdirect advises rinsing with water or milk after vomiting, and waiting at least 30 minutes before brushing (healthdirect). Better Health Channel’s pregnancy page and the ADA suggest waiting about an hour, with an optional fluoride rinse or toothpaste smear while you wait (Better Health Channel; teeth.org.au).
Sources differ slightly on exact timing. The practical steps stay the same: rinse first, wait, then brush with fluoride toothpaste without scrubbing hard. See also looking after your teeth when you’re unwell.
Why do regular check-ups still matter?
Regular dental check-ups matter in pregnancy because gum changes and acid from vomiting can build up quietly. Better Health Channel advises visiting the dentist before and during pregnancy, and always telling the dental team if you are pregnant (Better Health Channel). Queensland Health and the ADA encourage a check-up if you are planning pregnancy or soon after you become pregnant (Queensland Health; teeth.org.au).
At AMK Dental Clinic in Mortlake, discuss your pregnancy with the dental team when you book or when you arrive. Your dentist can examine your teeth and gums, advise on home care, and talk through any treatment or imaging that may be relevant for you. Decisions about X-rays sit with your dentist after they know you are pregnant — this page does not set absolute rules about imaging.
A professional clean may be part of a visit. See what happens at a scale and clean and check-ups and cleans. If treatment beyond home care is recommended, you receive an itemised written estimate before it goes ahead. Your dentist will discuss benefits, risks and alternatives with you. Results vary between people.

Common questions
Can pregnancy affect my gums?
Yes. Hormone changes in pregnancy can make gums more reactive to plaque, so they may become red, swollen or bleed more readily when you brush or clean between the teeth. Better Health Channel and the Australian Dental Association describe this pattern. Keep cleaning carefully and book a check-up at AMK Dental Clinic in Mortlake if bleeding continues. This page does not diagnose gum disease.
Should I brush after morning sickness?
Not straight away. Rinse with water first, then wait before brushing so stomach acid does not soften enamel while you scrub. Healthdirect advises waiting at least 30 minutes after acid exposure; Better Health Channel’s pregnancy page suggests waiting about an hour. Ask your dentist at AMK Dental Clinic what timing suits you. See our guide on looking after your teeth when you are unwell.
Should I tell the dentist I am pregnant?
Yes. Better Health Channel, Queensland Health and the Australian Dental Association all advise telling your dental practitioner if you are pregnant or think you may be. The team can plan your visit and discuss any imaging or treatment with you. At AMK Dental Clinic in Mortlake, mention pregnancy when you book or when you arrive.
