Although commonly advertised for gut health, we’re starting to see the release of probiotics for oral health.
With the increase of research into preventative dental care, probiotics suggest a new option to help keep mouths healthy.
What are probiotics?
Probiotics are essentially live friendly bacteria that are beneficial to health. According to the American Journal of Clinical Nutrition, probiotics can boost your immune system and stop pathogens from binding to the body.
Probiotics are found in supplements and some foods, such as yoghurt, kefir, cultured cottage cheese, buttermilk, sauerkraut, Kombucha tea and other fermented foods.
The use of probiotics for oral health is one of the exciting discoveries that shows the association between the food you eat and disease prevention. While gut health probiotics are taken in capsule form, dental probiotics are in lozenge form so that they are dissolved in the mouth to colonise the oral cavity. Scientists have isolated certain strains of bacteria (like S. salivarius, lactobacilli, L. reuteri and W. cibaria) that are showing promising results in improving oral health.
A probiotic must stick to the tooth surfaces and integrate into the bacterial biofilm in order to have a beneficial effect in preventing decay. They should also metabolise sugars to result in low acid production.
Several studies have shown that daily consumption of dairy products (yoghurt, milk, cheese) containing probiotics has led to a decrease in plaque and the number of bacteria in saliva. Incorporating probiotics into chewing gum or lozenges also showed results that help prevent decay.
Gum disease is a destructive disease that affects all supporting tissues of the teeth, including the jawbone. The main pathogens that affect the gums have virulent characteristics such as colonising under the gums and causing tissue damage. Various studies have shown lactobacilli (a probiotic bacteria) can stop the growth of harmful bacteria that cause gum disease. Another researcher has found L. reuteri (another probiotic bacteria) colonised the area and reduced plaque in moderate to severe gum disease patients. They also found that individuals who consumed dairy products with lactobacilli regularly have healthier gums.
A company in Switzerland called Sunstar has recently begun marketing the first probiotic specifically formulated to fight gum disease. Gum PerioBalance contains a patented combination of two strains of L. reuteri which helps to fight bacteria causing decay and gum disease.
Bad breath can be caused by various factors such as consumption of certain foods, poor oral hygiene, metabolic disorders or airway infections. Specifically, it is caused by bacteria that degrade salivary protein and turn it into volatile sulphur compounds. Researchers have found certain probiotics can inhibit the production of volatile sulphur compounds in the mouth. Regular gargling of a solution containing probiotics (W. cibaria/S. salivarius) resulted in a reduction in a reduction in bad breath.
Are probiotics bad for anyone?
As probiotics are live bacteria, patients that are immunocompromised wouldn’t be ideal candidates. Patients undergoing chemotherapy, suffering from HIV/AIDS or other conditions that affect the immune systems wouldn’t be a good candidate for probiotics. It is better to manage these patients with xylitol or other oral biofilm management.
Probiotics and oral health: Our Review
Probiotics are representing a new era of research in oral medicine. Initial research into the field is showing encouraging results. However, numerous randomised clinical studies will be required to clearly establish the potential of probiotics in preventing and treating oral infections. Such studies will allow identification of the probiotics that are best suited to oral use along with the appropriate method of delivery.
