What causes you to lose your teeth during pregnancy?

Pregnancy brings a lot of changes to your body, and your mouth is no exception. Many women in Oxnard, Ventura, Port Hueneme, and throughout Ventura County wonder: “Is it true that you lose a tooth with every pregnancy?” or even search “What causes you to lose your teeth during pregnancy?”

The good news is that dental experts confirm that pregnancy does not directly cause teeth to fall out. What it does do is create conditions that make your teeth more vulnerable, unless you take steps to protect them. Here’s what you need to know.

How does pregnancy affect your teeth?

During pregnancy, individuals may be at increased risk for oral conditions such as gingivitis and dental caries. Several specific factors are at play:

Hormonal changes and gum inflammation

When you’re pregnant, estrogen and progesterone levels rise significantly.

• Gingivitis occurs when the gums become red and swollen from inflammation that may be aggravated by changing hormones during pregnancy.
• If gingivitis is not treated, the bone that supports the teeth can be lost, and the gums can become infected.

Morning sickness and acid erosion

If you experience vomiting or acid reflux during pregnancy, stomach acids can come into contact with your teeth repeatedly.

• Constant exposure to this acid can soften and wear down enamel, that is the hard outside layer of your teeth.
• Women should not brush their teeth immediately after vomiting, instead, rinse with water or a baking soda solution first, then brush 30 minutes later.

Changes in eating habits

Many pregnant women snack more frequently throughout the day.

• More frequent eating means more time that bacteria in your mouth can feed on sugars and produce the acids that cause cavities.
• If you are eating more carbohydrates than usual, this offers extra fuel for the bacteria that cause tooth decay.

Is it true that women lose a tooth with every pregnancy?

This is one of the most common dental myths passed down through generations. The truth: tooth decay and tooth loss typically result from long-term factors such as poor oral hygiene, gum disease, or untreated cavities, not pregnancy itself.

Pregnancy increases your risk, but it doesn’t make tooth loss inevitable. With proper care, pregnant women have no reason to lose teeth.

How common is pregnancy gingivitis?

Very common. About 60% to 75% of pregnant women have gingivitis, an early stage of periodontal disease.

• This is why regular dental visits during pregnancy are so important, catching gum inflammation early prevents it from progressing to more serious disease.
• Teeth with little bone support can become loose and may eventually need to be extracted.

Periodontitis has also been associated with poor pregnancy outcomes, including preterm birth and low birth weight. Protecting your gums protects your baby, too.

How to protect your teeth during pregnancy

• Brush with fluoride toothpaste at least twice a day (after breakfast and before bed)
• Floss once daily to remove plaque between teeth
• Rinse with water after vomiting, wait 30 minutes before brushing
• Limit sugary snacks and drinks between meals
• Stay hydrated, dry mouth increases cavity risk

Don’t skip your dental appointments

The ADA encourages all pregnant persons to have a regular dental examination and dental treatment as needed throughout all stages of pregnancy.

• Preventive, diagnostic and restorative treatment is safe throughout pregnancy.
• You may need more frequent cleanings during pregnancy, or an anti-microbial mouth rinse.
• Your dentist may recommend rinsing your mouth with a teaspoon of baking soda mixed with water to cleanse away excess acids.

When should you see a dentist during pregnancy?

• Before pregnancy: If you’re planning to become pregnant, schedule a dental checkup to address any cavities, infections, or gum issues beforehand.
• During pregnancy: Don’t wait until something hurts. Delaying treatment may result in more complex problems. Routine cleanings, fillings, and even emergency procedures like root canals can be safe during pregnancy.

If you notice any of the following, call your dentist right away:

• Bleeding gums when brushing or flossing
• Gum swelling, redness, or tenderness
• Tooth sensitivity or pain
• Loose teeth
