How does pregnancy affect my oral health?

It's a myth that calcium is lost from the mother's teeth and "one tooth is lost with every pregnancy." But you may experience some changes in your oral health during pregnancy. The primary change is a surge in hormones-particularly an increase in oestrogens and progesterone which is linked to an increase in the amount of plaque on your teeth.

How does a build-up of plaque affect me?

If the plaque isn't removed, it can cause gingivitis:- red, swollen, tender gums that are more likely to bleed. So-called "pregnancy gingivitis" affects most pregnant women to some degree, and generally begins to occur in the second trimester. If you already have gingivitis, the condition is likely to worsen during pregnancy. If untreated, gingivitis can lead to periodontal disease, a more serious form of gum disease.

Pregnant women are also at risk for developing pregnancy tumours: inflammatory, benign growths that develop when swollen gums become irritated. Normally, the tumours are left alone and will usually shrink on their own. But if a tumour is uncomfortable and interferes with chewing, brushing or other oral hygiene procedures, the dentist may decide to remove it.

How can I prevent these problems?

You can prevent gingivitis by keeping your teeth clean, especially near the gum line. You should brush with fluoride toothpaste at least twice a day and after each meal when possible. You should also floss thoroughly each day. If tooth brushing causes morning sickness, rinse your mouth with water or with anti-plaque and fluoride mouthwashes. Good nutrition, particularly plenty of vitamin C and B12-help keep the oral cavity healthy and strong. More frequent cleanings from the dentist will help control plaque and prevent gingivitis. Controlling plaque also will reduce gum irritation and decrease the likelihood of pregnancy tumours.

When should I see my dentist?

If you're planning to become pregnant or suspect you're pregnant, you should see a dentist right away. Otherwise, you should schedule a check-up in your first trimester for a cleaning. Your dentist will assess your oral condition and map out a dental plan for the rest of your pregnancy. A visit to the dentist also is recommended in the second trimester for a cleaning, to monitor changes and to gauge the effectiveness of your oral hygiene. Depending on the patient, another appointment may be scheduled early in the third trimester, but these appointments should be kept as brief as possible.

Are there any procedures I should avoid?

Non-emergency procedures generally can be performed throughout pregnancy, but the best time for any dental treatment is between the fourth and sixth months. Women with dental emergencies that create severe pain can be treated at any time during the pregnancy, but your doctor should be consulted during emergencies that require anaesthesia or when medication is being prescribed. Only X-rays that are needed for emergencies should be taken during pregnancy. Lastly, elective procedures that can be postponed should be delayed until after the baby's birth.
