Slippery elm bark (Ulmus rubra) has been used traditionally in North American herbal medicine, including by various Indigenous peoples and early settlers, to support oral health and soothe the mouth and throat. Its mucilaginous (gel-like) texture, when mixed with water, is thought to form a protective layer over mucous membranes, which may help relieve irritation caused by inflammation or minor wounds. Specifically for the gums, folk remedies have included using slippery elm bark powder as a poultice or in lozenges to ease discomfort from sore gums or mouth ulcers.

However, clinical evidence supporting its effectiveness specifically for gum health is limited. The majority of modern scientific research on slippery elm focuses on its use for gastrointestinal conditions, thanks to its demulcent properties. There are no robust clinical trials demonstrating a direct benefit of slippery elm bark for gum disease, gingivitis, or other periodontal conditions. Most references in the context of oral health are found in traditional herbal texts or anecdotal reports rather than peer-reviewed studies.

In summary, while there is a strong tradition of using slippery elm bark for soothing oral and gum irritation, scientific validation for these effects remains minimal, and its use is primarily justified by historical and traditional practice rather than modern scientific research.
