Hello. This is pharmacist Jinny.
Recently, more and more people are saying, “I was surprised by the smell of my breath” while wearing a mask. This is because wearing a mask inhibits the supply of oxygen, creating a favorable environment for harmful bacteria in the mouth. 

The proliferated harmful bacteria not only cause simple bad breath, but also cause tooth decay and periodontitis, threatening overall oral health.

If so, what are some ways to suppress the growth of these harmful bacteria? Recently, the most attention in academia is the intake of 'lactic acid bacteria' . You are probably consuming lactic acid bacteria knowing that they are beneficial for gut health. So today, we're going to talk about the oral health-related benefits of probiotics.

1.  Improve bad breath
If you look at the name of the lactic acid bacteria, you can tell which genus and species it belongs to. The species 'Salivarius' of the genus 'Lactobacillus' is a species that has been reported in many academic studies related to oral health.

In 2010, in Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, a paper was published  on the effect of taking a pill containing Lactobacillus salivarius and xylitol on bad breath .

“ Oral intake of Lactobacillus lactic acid bacteria primarily improved physiological bad breath and also showed beneficial effects on periodontal bleeding. ”
Reference papers :  Tomoyuki Iwamoto, Nao Suzuki, Kazunari Tanabe, Toru Takeshita, Takao Hirofuji (2010). Effects of probiotic Lactobacillus salivarius WB21 on halitosis and oral health: an open-label pilot trial. Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology. 110(2): 201-208.
2.  Antibacterial action
Another lactic acid bacterium that has accumulated a lot of oral research is 'Lactobacillus reuteri'. This strain is found in human breast milk and is passed from mother to child through lactation. So when you stop breastfeeding, it starts to decrease gradually.

Recently, the domestic medical community has found that Lactobacillus reuteri has a strong antibacterial effect against bacteria that cause periodontal disease and tooth decay .

“ As a result, Lactobacillus reuteri can inhibit the production of CH₃SH (methylmercaptan) by nucleatum and gingivalis, as well as the growth of periodontal disease-causing bacteria and mutans. ”
Reference papers:  Kang , MS., Oh, JS., Lee, HC. et al (2011). Inhibitory effect of Lactobacillus reuteri on periodontopathic and cariogenic bacteria. J Microbiol. 49: 193–199.

3.  Relief of chronic periodontitis
Have you ever experienced swelling and bleeding gums? 
This is also a phenomenon that occurs due to the excessive proliferation of harmful bacteria in the mouth. In particular, caffeine intake, drinking alcohol, and smoking dry the mouth, creating a favorable environment for bacteria to thrive. 

In this regard, a study using Lactobacillus reuteri as an adjuvant for the treatment of chronic periodontitis in smokers was published in Beneficial Microbes in 2019 .

“ The adjuvant use of Lactobacillus reuteri in the treatment of chronic periodontitis is effective in controlling the inflammation of the gums. (abbreviation) ”
Reference papers:  Theodoro LH, Cláudio MM, Nuernberg MAA, Miessi DMJ, Batista JA, Duque C, Garcia VG (2019). Effects of Lactobacillus reuteri as an adjunct to the treatment of periodontitis in smokers: randomized clinical trial. Benef Microbes. 10(4):375-384.
Today , we looked at the oral health-related benefits of lactic acid bacteria . It is also good to know that different types of lactic acid bacteria can have different effects on oral health. Moreover, don't forget that proper brushing and eating habits are also important for comprehensive oral health care.
I hope you have a healthy body and mind. More than that, it was Jinny.
