Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Zinc is scientifically recognized as a trace mineral important for oral health, particularly in supporting the teeth and overall oral cavity. Several studies have shown that zinc possesses antibacterial properties that can inhibit the growth of oral bacteria associated with dental caries and periodontal disease. Zinc compounds are commonly included in toothpaste and mouth rinses, where they help reduce dental plaque, control oral malodor (bad breath), and prevent calculus (tartar) formation. Additionally, zinc plays a role in the structure and function of enzymes involved in the maintenance and repair of oral tissues, including the gums and mucosa.

However, while zinc supports the oral environment and helps prevent conditions that can negatively impact teeth, there is less direct evidence that zinc supplementation alone improves tooth strength or structure in healthy individuals. Most benefits are related to its antimicrobial effects and its role in supporting the immune response within the oral cavity. Clinical studies and reviews (such as those published in the Journal of Clinical Periodontology and Cochrane Reviews) support the adjunctive use of zinc in oral hygiene products for managing plaque and gingivitis. Therefore, the use of zinc for supporting the teeth is scientifically validated but primarily as a preventive and supportive agent rather than a direct enhancer of tooth mineralization.
