What the research on cranberries shows
While the evidence suggests promising outcomes, our research papers identified significant gaps in the current research on cranberries and their components, particularly their application in oral health and integration into dental products. Further studies are necessary to investigate the properties of cranberries beyond their well-known benefits for urinary tract infections.
Additionally, online information about how cranberries are used in specific cultures or religions is limited.5 Although holistic or alternative medicine has significance in different cultures and faiths, there needs to be a more thorough study of the specific uses of cranberries. Studies on cranberry extract’s effects on dental health are limited, with the earliest research dating back to only 2004.6
Many of these studies lack standardized protocols, making comparisons difficult due to the wide range of methods used, including variations in age groups, sample sizes, concentrations, and forms of cranberry extract (mouthwash or gel). A more comprehensive and systematic study is required to identify the most effective uses of cranberry extract for dental health. Yet, there’s a role for cranberries for those who prefer to take a more holistic/adjunct approach to oral prevention.
How we use this information with our patients
During our investigation, we consulted with Daivati Bharadvaj, ND, a community advisor and primary care physician specializing in botanical medicine. She recommended we explore additional databases, such as the National University of Natural Medicine, and suggested critically reviewing the studies.
Our interprofessional collaboration, which focuses on holistic approaches and sustainable dietary choices, has dramatically enhanced our ability to provide patients personalized dental hygiene preventive education. Dr. Bharadvaj also shared a recipe for a cranberry-based oral rinse that we share here.
What makes cranberries a “berry” good choice as an alternative or adjunct to prevention practices? Many people have limited access to affordable health care or do not seek care due to stigma or misconceptions.7 Cranberries are widely available and offer various health benefits. Additionally, the cost of mouth rinses and their added ingredients may be unappealing to some people.
Cranberries are emerging as a promising and healthy alternative for promoting gum and dental health. For those seeking a more sustainable option, cranberries show potential as a complementary addition, and further research could help us unlock the full benefits they may offer.
