Recently, a patient asked whether there was any relationship between using Sensodyne-F (a desensitizing toothpaste) and insomnia. I couldn't answer him definitively. However, a quick literature search on the Pubmed database including some of the major medicinal components of the toothpaste revealed no known relationship. I did find an anecdote on Google, but no scientific literature.
