How Oral Probiotics Work

Commercial developments have immensely fueled interest in probiotics in the dentistry community. Also, documented clinical studies and trials have played a major role in spreading probiotics’ popularity. 

Recent studies even indicate how probiotics can be utilized to flatten the COVID-19 pandemic curve. Logically, any medical caregiver, including dentists, periodontists, and other medical practitioners, agree that they can readily welcome anything that strengthens the immune system. This is so long as it helps fight the novel virus.

Apart from COVID-19, most studies primarily focus on probiotics application in dentistry. If you’re wondering whether dentists should recommend them, some do, depending on your oral microbiome, as you’ll see later.

How to Make Probiotic Work Well to Get the Most out of It 

Many studies show that S. salivarius K12 and m18 are the most effective probiotics. These two supplements have tremendous beneficial effects on halitosis. However, to ensure maximum effectiveness, you must have used mouth rinse between 3 and 7 days prior. Note that wiping the existing microbiome out of your mouth cavity is crucial for some probiotics to fully effect. 

Contrary to that, some probiotics perform excellently without removing the microbiome in the oral cavity. These probiotics are; L.reuteri and L.paracasei. Generally, this shows that there are specific probiotics to consider as there are various species with various strain-dependent effects. 

As already mentioned, you can expect a significant difference after about four weeks of oral probiotics. If that doesn’t happen, it’s best to reset your current oral microbiome by using an antiseptic mouthwash for about a week before taking the oral probiotic again.

Note that the microbiome in your oral cavity is unique to you—everybody has a different microbiome. That means that even the probiotic effects may differ depending on the oral microbiome in your oral cavity. Tests involving the oral microbiome help identify the right probiotic supplement ideal for your oral cavity. Moreover, the tests also determine if your microbiome needs a mouthwash reset.

About the Right way to Take Oral Probiotics

Aside from supplements, surprisingly, probiotics can also be taken in food. In fact, food sources like fermented and enriched are far better, more absorbable, and tolerable than supplements. Food sources that are enriched and contain sufficient amounts of probiotics include; soft cheese, sourdough bread, milk, sour pickles, and yogurt.

Probiotic supplements like powder mouthwash or pills are more concentrated than probiotics in various foods. Note that even though oral probiotics are safe for human consumption, it’s wise you don’t exceed the dosage recommended by the manufacturer. Remember to consult you’re doctor, dentist, or periodontist whether or not you should include probiotics in your dental or medical regimen.

Consider asking your dental caregiver if you don’t know the accurate probiotic dosage suitable for your condition. This is because probiotic supplements have different dosages for children, pregnant mothers, and seniors.

More importantly, if you have an existing autoimmune disorder or are at high risk of infection, you should beware earlier about the possibility of experiencing side effects, though mild, in your first attempt to use oral probiotics. Notably, the side effects are usually associated with the gut.

Advantages that Come with Using Probiotics

Common over-the-counter probiotic supplements fight bad bacteria in the oral cavity or mask bad breath. Some of these supplements primarily target the VSCs. Notably, this is a short-lived solution due to the quick repopulation of the bad bacteria.

Also, whenever there’s a reduced population of bacteria in oral cavity, the good or bad usually rush in as replacement. It’s an important aspect worth considering since it’s when the probiotics come into play. That means if the population of bad bacteria surpasses the good, then probiotics will slash down the bad bacteria population.

This gives the good bacteria to populate and protect your teeth and gums. Overall, this shows that probiotics assist good bacteria in populating, which curtails pathogenic growth.

Surprisingly the human mouth houses more than 700 bacterial species. But oral probiotics mainly focus on sustaining bacteria that don’t produce VSCs (volatile sulfur compounds). According to some scientific findings, weekly daily probiotic intake can cause a tremendous fall in VSCs. 

The findings were from the research of which 85% experienced the phenomenon mentioned earlier. Following two weeks of continued probiotic supplement use maintained immense reduced VSC levels for more than 85% of study participants. Through the participants, the treatment model also proved that probiotics are an excellent long-term bad breath solution.

Side Effects of Probiotics

You already know how long it takes for probiotics to work on your teeth. What are the potential side effects of using probiotics? So long as you’re healthy and don’t have any underlying medical condition. 

As already mentioned, it’s best to steer clear of probiotics if you have an autoimmune condition. Advisably, it would help to seek medical advice from your dental caregiver even if you’re healthy. This involves the ideal probiotic suitable for you and the dosage.

Final Takeaway 

Oral Probiotics have proven to be an effective solution for combating teeth-related problems and diseases. Though thorough oral probiotic research began a few years ago, it’s apparent that it’s gained significant popularity in dentistry. 

Fortunately, some dentists recommend various types of probiotics depending on the state of your oral cavity. When choosing an oral probiotic, it’s wise to choose one with at least 3 billion CFUs. Moreover, the industry is flooded with multiple probiotic supplements. So before visiting your local chemist, seek a credible recommendation from your dentist.
