How Probiotics Improve Oral Health

Dentist in Bellingham, WA

Probiotics are typically advertised as being helpful for digestion. However, studies have shown that they can also improve oral health. Probiotics are beneficial for fighting infections that lead to oral disease.  

Reducing Gingivitis 

A study published in Contemporary Clinical Dentistry has found that probiotics can reduce gum bleeding in patients with moderate to severe gingivitis. In the trial, children were given either a placebo or two different combinations of probiotics. At the three-week mark, it was discovered that children who took probiotics had significant improvements in their gingival status. 

Combating Periodontitis 

Periodontitis is another oral disease that probiotics have been shown to fight. Periodontitis is caused by harmful bacteria that separate teeth from the gums creating pockets that can become infected. Probiotics can fight harmful bacteria and lessen the inflammation to help heal the mouth. 

Fighting Cavities 

Another finding from the trial of the Contemporary Clinical Dentistry showed that children who took probiotics also saw a significant decrease in plaque. The reduction of plaque leads to less decay. Probiotics fight the plaque and occupy the spaces on the teeth where bad bacteria thrive.  

Minimizing Bad Breath 

Another benefit of probiotics is the effect they have on bad breath. Bad breath is usually caused by volatile sulfur compound bacteria releasing odor-causing gases. Because probiotics are healthy bacteria, it is believed that they can eliminate the bad bacteria and maintain a healthy bacteria balance in your mouth.  

The benefits of probiotics are not just limited to the digestive health. Researchers continue to conduct studies to discover new ways probiotics contribute to a healthy mouth and body.
