Yes — and it is often important
Routine dental care during pregnancy is safe and should not be postponed. Untreated infection carries far greater risk to both mother and baby than the treatment itself. Always tell your dentist that you are pregnant and how many weeks along.
The best timing
The second trimester is generally the most comfortable window for elective treatment. In the first trimester nausea is often at its worst, and in the third lying back for long periods becomes uncomfortable. Urgent treatment, however, should never be delayed for the sake of timing.
Anaesthetic and X-rays
Local anaesthetics used in dentistry are considered safe in pregnancy. X-rays are avoided where possible, but if one is clinically necessary, modern digital imaging with abdominal shielding delivers an extremely low dose and is not a reason to leave an infection untreated.
Pregnancy gingivitis
Hormonal changes make the gums more reactive to plaque, and many women notice bleeding gums for the first time during pregnancy. Meticulous brushing and interdental cleaning, plus a hygiene appointment, usually bring it under control. If morning sickness is frequent, rinse with water rather than brushing immediately, as brushing enamel softened by stomach acid causes wear.
