Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Alum (potassium aluminum sulfate) has been traditionally used in oral care, particularly in some cultures, as a home remedy for strengthening gums, reducing toothache, and acting as an astringent to reduce bleeding. Its use in dental powders and mouth rinses is centuries old, especially in South Asia and the Middle East. The belief is that alum’s astringent properties help to tighten gum tissue and reduce inflammation, which indirectly supports oral health and may provide a temporary feeling of tooth and gum strength.

From a scientific standpoint, evidence supporting alum for "supporting the teeth" is limited. Some laboratory studies have shown that alum possesses antimicrobial properties that may inhibit the growth of oral bacteria, potentially reducing plaque formation and gum disease. However, these effects are not robustly demonstrated in large clinical trials, and alum is not endorsed by mainstream dental organizations for the prevention or treatment of dental caries or periodontal disease.

In summary, while alum has a strong traditional basis for use in oral health and some preliminary evidence of antibacterial and astringent effects, there is insufficient scientific validation for its effectiveness in supporting the teeth or gum health beyond short-term, symptomatic relief. It should be used with caution, as excessive or prolonged use can irritate oral tissues.
