Are Probiotics Good For Your Teeth?

September 15, 2022

Most of us know that probiotics – the bacteria and yeasts that are good for you – benefit our digestive tract, but what other beneficial effects do they have?



While the Food and Drug Administration has not officially placed its stamp of approval on the use of probiotics to promote oral health, several recent studies indicate that these good bacteria and yeasts can be good for our teeth and gums.


The Benefits of Probiotics For Your Oral Health

While probiotics work by being ingested in targeting your gut health, they can also affect your oral hygiene and health. Unlike harmful bacteria that can lead to illnesses, infection, and decay, probiotics help keep your gut balanced with healthy bacteria.

Listed below are a few ways in which probiotics might promote better oral hygiene and oral health.


Prevention of plaque and tooth decay

Our mouths are loaded with bacteria, both good and bad. Streptococcus mutans, a certain type of bad bacteria, turns sugar into lactic acid in the mouth and creates an acidic environment contributing to the development of plaque and tooth decay.

On the other hand, a common probiotic in the digestive system, Bifidobacterium, has been found to prevent tooth decay by reducing the number of Strep bacteria in the mouth. A good balance between these two types of bacteria could slow down or prevent decay that can lead to a filling, tooth repair, or root canal.


Managing the symptoms of gingivitis and gum inflammation

Gingivitis is a common gum (periodontal) disease known for symptoms such as sensitive teeth and sore, swollen, and bleeding gums. A recent study of individuals with gum disease found that those receiving a supplement containing Lactobacillus reuteri probiotic displayed few symptoms and had less plaque than those participants in the study who were given a placebo. A similar study found that participants taking supplements containing the bacteria Lactobacillus brevis had a marked decrease in oral inflammation.


Prevention of halitosis

Bad breath is often caused by an imbalance of harmful bacteria in the mouth and gut. Several studies seem to indicate that daily doses of Lactobacillus brevis substantially reduced the number of harmful bacteria in the mouth.


Possible prevention of oral cancer

A study conducted in 2013 found that a bacteria known as Lactobacillus salivarius reduced oral cancer in rats, but additional research needs to be done to see if it would be equally effective in humans. It’s important to note that while ingestive probiotics is beneficial, it shouldn’t be your only source of protection and prevention against disease. You should also maintain a balanced diet, brush your teeth at least twice daily and visit a dental professional for routine checkups.


Sources of Probiotics

Probiotics occur naturally in a number of foods, including yogurt, cultured cottage cheese, buttermilk, kefir, and tempeh. They’re also found in fermented vegetables like sauerkraut and kimchi. You can also consume prebiotics that enhance the absorption of probiotics in your gut. Common prebiotics include onions, artichokes, garlic, and raw asparagus and leeks.


If you think you’re not getting enough probiotics through your diet, numerous supplements are available in the form of pills, capsules, and powders. Before taking any supplements, however, be sure to consult with your primary care physician.

Pregnancy is a time of excitement, anticipation, and transformation. As your body adapts to nurture new life, your needs evolve—including your dental care. At Stephens Dentistry, we’re passionate about supporting expectant mothers through every stage of this journey. Understanding the connection between oral health and pregnancy is not just important for your smile, but for the wellbeing of both you and your baby.  How Pregnancy Impacts Oral Health Pregnancy brings about a surge in hormones, especially estrogen and progesterone, which can have a profound effect on your gums and teeth. Many women notice changes in their oral health during pregnancy, including increased sensitivity, swelling, or bleeding gums. These shifts aren't just uncomfortable—they can also signal conditions that need attention to safeguard your overall health. Pregnancy Gingivitis: What You Need to Know One of the most common dental issues during pregnancy is pregnancy gingivitis. According to the Centers for Disease Control and Prevention , up to 60–75% of pregnant women develop gingivitis, which is characterized by red, swollen, and bleeding gums. This occurs because hormonal changes heighten the body’s response to the bacteria in dental plaque. If left untreated, gingivitis can progress to periodontitis—a more serious gum infection that can cause tooth loss and has been linked to health risks beyond the mouth. Oral Health and Birth Outcomes The importance of oral health during pregnancy goes beyond comfort and aesthetics. Research has shown a significant link between maternal gum disease and adverse pregnancy outcomes, such as preterm birth and low birth weight. A systematic review published in the Journal of Dental Research found that women with periodontal disease may be more likely to deliver prematurely or have babies with low birth weights. Although more research is ongoing, the potential connection means that taking care of your gums and teeth is an essential part of prenatal health. Why Dental Care Shouldn’t Wait Some expectant mothers worry about dental treatments during pregnancy. The good news is that routine dental care—including cleanings and necessary treatments—are not only safe but recommended during pregnancy. The American College of Obstetricians and Gynecologists confirms that preventive dental work is important and can be performed safely, especially in the second trimester. Delaying care can allow small problems to become bigger ones, and untreated infections can pose a risk to both you and your baby. If you are planning to become pregnant, scheduling a dental checkup beforehand is an excellent way to get ahead of any issues. Practical Tips for Expectant Mothers Maintaining oral health during pregnancy doesn’t have to be complicated. Here are some tips to keep your smile healthy throughout your pregnancy: Brush and Floss Regularly: Aim to brush twice a day with fluoride toothpaste and floss daily. This helps remove plaque and reduce your risk of gingivitis. Eat a Balanced Diet: Focus on nutritious foods rich in calcium, vitamin D, and protein, which support both your oral and overall health. Manage Morning Sickness: If you experience vomiting, rinse your mouth with water or a fluoride mouthwash rather than brushing immediately afterward, as stomach acid can soften tooth enamel. Stay Hydrated: Drinking plenty of water helps wash away food particles and bacteria, and can also help combat dry mouth, which is common in pregnancy. Schedule Regular Dental Visits: Let your dental team know you are pregnant so they can tailor your care. At Stephens Dentistry, we take extra precautions to ensure your comfort and safety during each visit. Learn more about our preventive dental services . Recognizing When to Call Your Dentist While mild gum sensitivity is common, it’s important to reach out to your dentist if you notice persistent bleeding, swelling, or pain. These symptoms could indicate an infection that needs prompt attention. If you develop a dental emergency during pregnancy, don’t hesitate to contact your dentist—timely care is always the best choice for both you and your baby.
