CBD- Better than Oral B

CBD- Better than Oral B

Flashing those pearly whites isn’t just great for appearance sake; maintaining dental health is essential to overall health. If your mouth is unhealthy it contains bacterium from infections and decay, which travels to your stomach and throughout the digestive track. The bacteria will then spread through your bloodstream and infect other areas of your body, including your organs. Implementation of daily dental health routines will keep your smile beautiful and your mouth healthy. Recently, a number of dental products containing cannabidiol (CBD) and symbiotic plant cannabinoids have been introduced to the marketplace; and studies are showing they might actually have a promising future in oral health.

The idea of incorporating hemp or cannabis in your oral routine may not be a familiar inference. But recent data shows that cannabinoids could become a staple in the dental field in the years ahead. Some of the leading manufacturers of toothpaste have taken note of research showing that CBD and the beneficial antimicrobial properties that are relevant to dental health.

A 2020 study conducted by researchers in Belgium showed that “cannabinoids were more effective in reducing the bacterial colony count in dental plaques as compared to well-established synthetic oral care products, such as Oral B and Colgate.” Better than Oral B? That can’t be right. Right?

 To demonstrate the conclusions of the researchers, they recruited healthy adults and arranged them into six different groups of ten each based on the Dutch periodontal scoring index (DPSI). These groups represented different levels of periodontal gum health.

In the follow up study, several samples of plaque were collected from intradental spaces between the participants/ teeth and placed on two separate Petri dishes.

A subsequent four divisions in the dishes were made, and on each section, cannabinoid (12.5%) or toothpaste (undiluted) was spread/streaked on the surface of the agar plate using micro-brush applicator.

Petri dish A - a combination of four plant cannabinoids – CBD, cannabichromene (CBC), cannabiniol (CBN), and cannabigerol (CBG) – were used. 

Petri dish B- cannabigerolic acid (CBGA), Oral B, Colgate, and Cannabite F (a toothpaste formulation of pomegranate and algae) were used.

The resulting bacterial colony count was much higher in the Colgate, Oral B and Cannabite F treatments, whereas a significantly less bacterium colony count was observed in all the cannabinoid treatments.

By highlighting the potential of CBD and other plant cannabinoids in the prevention of dental plaque formation, these emerging studies hint that the role of cannabinoids in dentistry could be vast.

The preface when drawing conclusions is, as always, that clinical trials are needed to fully assess the long-term efficacy and safety of CBD-infused dental hygiene products. In addition, we will need to keep a critical eye on whether these results can be duplicated, especially given that the authors of these papers may benefit financially from their findings. Namely, Stahl is a founder of CannIBite, a company involved in making cannabinoid infused dental products. We must of course consider that as with most studies, funding comes from those parties most driven to prove their theories correct.
