According to The World Health Organization, cannabis is the most used recreational drug. Regular cannabis use can lead to a higher incidence of cavities, gum disease, oral cancer, gingivitis, and periodontal disease. Your dental hygienist can help you understand the risks of cannabis use while she regularly monitors your oral health for any unplanned consequences. It is important for your dental hygienist to know all your medical conditions and any medications you may be taking in order to provide safe and effective recommendations and treatments. The more your dental hygienist knows about your personal health history, the more customized your dental hygiene care can be.
