Healthy Pregnancy

Oral Health

Taking care of your teeth and gums is very important when you are pregnant. Hormonal changes during pregnancy can increase your risk of developing periodontal (gum and bone) disease. Poor oral health may also affect the health of your developing baby.

Important Facts

Pregnant women with periodontal disease may have a higher risk of delivering a pre-term or low birth weight baby. Babies who are pre-term or low birth weight have a higher incidence of developmental complications, asthma, ear infections, birth abnormalities, behavioral difficulties, and a higher risk of infant death.

Eating well is important for your oral health. It can also help to build strong teeth and bones in your developing baby. During pregnancy, you need to eat the right kinds of food and in the right amounts – making sure to get enough calcium, Vitamins A, C, and D, as well as protein and phosphorous. Taking a multivitamin can help.

Regular dental checkups and cleanings by your dental professional are the best ways to detect and prevent periodontal disease. Schedule a checkup in your first trimester to have your teeth cleaned and your oral health assessed. If you require dental work, the best time to schedule it is between the fourth and sixth month of your pregnancy (the second trimester). X-rays of your mouth should only be taken in an emergency.

Morning sickness can cause tooth decay. Stomach acid left on the teeth can damage the surface of your teeth and promote tooth decay. If you vomit, rinse your mouth with water or with a fluoride mouthwash as soon as you can afterward.

Next Steps

Brush your teeth at least twice a day with a soft toothbrush using a fluoride toothpaste. Carefully clean your teeth at the gum line, where gum disease starts. Don’t forget to floss!

If you’re not sure if you are brushing and flossing correctly, talk to your dental professional. He or she can show you how, so you can care for your teeth and gums properly.

Be sure to continue with routine dental checkups during and after your pregnancy.
