Dental care during pregnancy in Singapore: safe cleanings and X-rays, the best time for treatment, and CHAS and polyclinic subsidies

Dental care during pregnancy is safe, and it matters more than usual. KKH's obstetricians say it's generally safe to go for a dental check-up while pregnant, and that pregnancy hormones make your gums more likely to swell and bleed. Scaling, polishing and fillings can all go ahead, ideally in the second trimester, and X-rays are done only when needed, with a lead apron to shield your baby. In Singapore, polyclinic dental care is subsidised and booked through HealthHub, and CHAS Blue and Orange cardholders get set subsidies at private CHAS dental clinics, for example up to $30 off scaling for CHAS Blue. This guide covers what's safe, when to go, what it costs and the daily routine that protects your teeth.

Why pregnancy is hard on your teeth and gums

Pregnancy doesn't take calcium out of your teeth; Thomson Medical's dentists call that a myth. The real changes are in your gums and your mouth's chemistry.

• Gum inflammation (pregnancy gingivitis): KKH says rising oestrogen and progesterone increase your risk of gingivitis, and that gums can bleed easily when you brush from around the second month. Thomson Medical puts it at 60 to 75% of pregnant women.
• Gum disease that goes deeper: when the inflammation reaches the bone that holds your teeth, KKH says it's called periodontitis, and teeth can become unstable and loose. Thomson Medical adds that periodontitis is linked to a higher risk of preterm birth and low birth weight.
• Pregnancy lumps on the gums: Raffles Medical's periodontist describes small gum lumps, called pregnancy epulis, that can grow along the gum line or between teeth. They usually go away after the birth, and can be removed under local anaesthetic if they bother you.
• Acid from morning sickness: stomach acid softens tooth enamel. Thomson Medical's advice is to rinse with water after vomiting and wait 30 minutes before brushing, so you don't scrub softened enamel away.
• Snacking and cravings: frequent sweet snacks and drinks give the bacteria that cause decay more to feed on, so brushing after meals matters more now.

If morning sickness is making brushing hard, our guide to morning sickness remedies in Singapore has ways to cope.

What's safe at the dentist when you're pregnant

Routine care doesn't need to wait until after the birth. Raffles Medical's dentists say routine dental checks are safe throughout pregnancy, as long as the dentist knows you're pregnant. Here's how the usual treatments line up:

A note on fillings: SingHealth's KKH guidance and ACOG don't say quite the same thing. ACOG treats dental treatment as safe in pregnancy; KKH specifically says to avoid silver fillings. White composite fillings avoid the question, and they're what polyclinics already use, so ask for them.

The best time for dental treatment

Whatever the stage, don't wait out a toothache or a swollen gum. An infection is a bigger worry for you and your baby than the treatment that clears it.

Dental X-rays in pregnancy

The rule is to have X-rays only when they change what your dentist will do. KKH's pregnancy guidance says to avoid X-rays unless your doctor orders one, and that you'll usually be given a lead apron to shield the baby if it's needed. SGH's radiology department asks every patient who might be pregnant to tell the staff before an X-ray. So say you're pregnant when you book and again in the chair.

If you had a dental X-ray before you knew you were pregnant, don't panic. KKH's guidance says accidental X-ray exposure, even in the first trimester, is not necessarily a reason to end a pregnancy. Mention it to your obstetrician at your next visit.

Dental subsidies and costs in Singapore

You have two subsidised routes for basic dental care: a polyclinic, or a private dental clinic that takes CHAS. MOH says polyclinic dental services are strictly by appointment and booked on HealthHub. They include scaling and polishing as well as fillings. Polyclinic care is already subsidised, so HealthHub notes that CHAS subsidies don't apply there.

At a private CHAS dental clinic, the subsidy depends on your card. CHAS Blue, CHAS Orange, Merdeka Generation and Pioneer Generation cardholders get dental subsidies; MOH extended preventive dental subsidies such as scaling and polishing to CHAS Orange from 1 October 2025. CHAS Green covers chronic conditions and Healthier SG screening, with no dental subsidy listed. These are MOH's maximum subsidies from 1 October 2025, next to MOH's typical private fees:

• Who gets which card: CHAS Blue is for households with a monthly income of $1,500 or less per person, and CHAS Orange for $1,501 to $2,300 per person.
• Claim limits: up to 2 consultations a calendar year, 6 months apart, plus up to 2 scaling, 2 polishing and 6 X-rays a year, CHAS says. If you had a check-up early in the year, plan your pregnancy visit around the 6-month gap.
• MediSave: MOH lists MediSave-accredited dental clinics, and Raffles Dental's list of MediSave-claimable procedures covers dental surgery, such as wisdom tooth surgery, rather than routine cleaning or fillings.
• Merdeka and Pioneer Generation subsidies are higher; check the CHAS website if you hold one of those cards.

Fees at private clinics outside CHAS vary, so ask for a quote before treatment.

A daily routine that protects your teeth

KKH's advice is simple: brush after each meal, floss daily and gargle with mouthwash. In practice:

Healthy habits now carry over to your baby. Our guide to kids' dental care in Singapore covers first teeth and the first dental visit, and our prenatal vitamins guide explains the calcium you need, from food first.

When to see a dentist quickly

• Gums that bleed every time you brush and aren't getting better after a few weeks of careful cleaning.
• A tooth that feels loose, or gums pulling back from your teeth. KKH says severe gum inflammation can loosen teeth.
• Toothache, or swelling of your gum or face, which can mean an infection.
• A gum lump that bleeds a lot, hurts or gets in the way of eating.

If you have swelling with a fever or difficulty swallowing, see a doctor the same day. Our guide to pregnancy discomforts by trimester covers the other aches you can expect.

Frequently asked questions

Is it safe to go to the dentist while pregnant?

Yes. KKH says it's generally safe to go for a dental check-up during pregnancy, and Raffles Medical's dentists say routine checks are safe throughout. Tell the dentist you're pregnant.

Can I have my teeth cleaned when pregnant?

Yes. Scaling and polishing treat the gum inflammation that pregnancy hormones make more likely. Thomson Medical says the second trimester is the best time for most treatment.

Are dental X-rays safe during pregnancy?

Have them only when your dentist needs one. KKH says to avoid X-rays unless ordered, and you'll usually get a lead apron to shield your baby; an accidental X-ray isn't in itself a reason to end a pregnancy.

Why do my gums bleed in pregnancy?

Rising oestrogen and progesterone make gums inflame more easily. KKH says bleeding when brushing often starts after the second month. Keep brushing and flossing gently, and see a dentist if it doesn't improve.

Can I use CHAS for dental care while pregnant?

Yes, if you hold a CHAS Blue, Orange, Merdeka or Pioneer Generation card and use a CHAS dental clinic. CHAS Green has no dental subsidy, and polyclinics are already subsidised, so CHAS isn't used there.

Should I avoid silver fillings while pregnant?

KKH's guidance is to avoid having silver (amalgam) fillings done during pregnancy. Ask for white composite fillings, which polyclinics already use in place of amalgam.
