Pregnancy and Dentistry

Is there any link between tooth decay and pregnancy?

Yes, there is a link between tooth decay and pregnancy, as hormonal changes can make gums more susceptible to problems and morning sickness can increase the risk of decay. Additionally, pregnancy-related cravings can lead to more frequent snacking on sugary or acidic foods, which can also increase the risk of cavities

How pregnancy can lead to tooth decay

• Hormonal changes: Pregnancy hormones can make gums more prone to inflammation, bleeding, and infection. This can indirectly lead to tooth decay if oral hygiene is compromised.

• Morning sickness: Vomiting exposes teeth to strong stomach acids, which can erode tooth enamel and increase the risk of decay.

• Dietary changes: Cravings for sweets or acidic foods can lead to more snacking, increasing the risk of cavities.

How to protect your teeth during pregnancy

• Practice good oral hygiene: Brush your teeth twice a day for at least two minutes with fluoride toothpaste. Floss daily and replace your toothbrush every three months.

• Prevent acid damage from vomiting: Rinse your mouth with water mixed with baking soda to neutralize acids after vomiting. Wait at least one hour before brushing your teeth to avoid further erosion.

• Maintain a healthy diet: Limit sugary and acidic foods and drinks. Opt for a balanced diet to support both your oral and overall health.

• Visit the dentist: See your dentist for a checkup. Your dental care will be free during pregnancy and up to a year after your baby is born if you have a maternity exemption card. Be sure to tell your dentist you are pregnant so they can provide appropriate care. 

Does pregnancy make your teeth weaker?

Pregnancy does not inherently weaken your teeth, but hormonal and lifestyle changes can increase your risk for dental issues like gum disease, cavities, and tooth erosion. Hormonal changes can make gums swell and bleed, while morning sickness can erode enamel due to stomach acid. Increased snacking on carbohydrates and avoiding brushing due to sensitive gums can also contribute to tooth problems. 

Hormonal changes

• Gingivitis: Pregnancy hormones can cause your gums to become swollen, red, and bleed easily, a condition called pregnancy gingivitis.

• Periodontitis: If untreated, gingivitis can advance to periodontitis, a more serious gum disease that can lead to tooth loosening or loss.

• Loose teeth: High levels of progesterone and estrogen can temporarily loosen the ligaments and bones that hold your teeth in place, though this is usually temporary.

Lifestyle and dietary changes

• Tooth enamel erosion: Morning sickness and vomiting expose your teeth to stomach acid, which can erode enamel and make teeth more susceptible to decay.

• Increased snacking: More frequent snacking, especially on sugary or starchy foods, can increase the amount of acid and plaque-producing bacteria in your mouth.

• Dietary needs: While the baby doesn't "steal" calcium from your teeth, the body's increased demand for calcium can make the mother's system experience a drop in it, potentially affecting bones and teeth.

• Prenatal vitamins: Some gummy prenatal vitamins contain sugar and can stick to teeth, especially if taken before bed, increasing the risk of decay. 

How to protect your teeth during pregnancy

• Maintain a good oral hygiene routine: Brush twice a day and floss daily, even if your gums bleed (talk to your dentist about reducing the bleeding).

• Rinse with water after vomiting: Rinse your mouth with water to wash away acid. Avoid brushing immediately after vomiting, as this can further erode enamel.

• Limit sugary snacks and drinks: Opt for healthier snacks like fruits and vegetables and choose water over sugary drinks.

• Prenatal vitamins: Consider chewable and sugar-free options if you're using gummy vitamins, or switch to a chewable tablet or capsule.

• Visit your dentist regularly: See your dentist for checkups and cleanings before, during, and after pregnancy. 

X-rays and anaesthesia?

Always tell your dentist if you are pregnant, especially if there is a chance that you will need an x-ray. Your dentist will usually wait until you've had the baby. X-rays during pregnancy do not carry risks to your unborn baby, such as miscarriage or birth defects but repeated exposure to radiation can potentially damage the body's cells in the long run, increasing risk of developing cancer. X-rays are very low doses of radiation and during pregnancy carry a minimal risk of exposing the unborn baby to radiation.
