Sensodyne Toothpaste Sensitivity Gum and Enamel Fluoride, Mint Flavor, 3.4 oz
Lower PFAS concern for toothpaste itself; aluminum tube risk remains unaddressed.
Sensodyne toothpaste formulation itself is not a known PFAS vector. The aluminum tube lining coating is undisclosed; some aluminum foil/tube linings historically contained PFAS water-barrier layers.

What Sensodyne Toothpaste Mint Flavor, is made of, ingredients and materials
Sensodyne Sensitivity Gum and Enamel is a gel toothpaste formulation in an aluminum/plastic laminate tube. The active ingredient is potassium nitrate (for sensitivity) and sodium fluoride (0.243% w/w for cavity prevention). Gel toothpastes in this class typically contain humectants, abrasives (silica or calcium carbonate), and mint flavoring; no known proprietary coatings or problematic binders distinguish this formulation from standard cosmetic-grade toothpastes.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Aluminum toothpaste tubes may be lined with epoxy or other polymer coatings that can contain PFAS to improve water and oxygen barrier properties. GSK does not publicly disclose tube lining composition or PFAS content for Sensodyne packaging; direct mouth contact with residual coating is unlikely given the brief application window and small quantity used per brushing.
Source, ATSDR ↗Fragrance allergens (mint flavoring)
Mint flavoring may contain limonene, menthol, or other natural or synthetic fragrance compounds known to trigger allergic contact reactions in sensitive individuals. Sensodyne does not break down fragrance components on the label; those with documented mint or menthol sensitivity should seek unflavored or alternative sensitivity toothpastes.
What’s reassuring
Formaldehyde / VOCs
No established recalls or third-party findings document formaldehyde-releasing preservatives (e.g., DMDM hydantoin, imidazolidinyl urea) in Sensodyne sensitivity formulations. Standard formulations of this brand typically use potassium sorbate or sodium benzoate, which do not release formaldehyde.
Source, ATSDR ↗Heavy metals
No published reports of lead, cadmium, or antimony contamination in Sensodyne toothpaste pigments or silica abrasives. FDA enforcement history does not list Sensodyne recalls for heavy metal content; however, GSK does not provide third-party heavy metal assay data for this product.
Source, FDA ↗Talc contamination
Sensodyne gel toothpaste formulations do not list talc as an ingredient and do not use talc-based mineral suspending agents; this hazard is not relevant to this product.
How is this PFAS grade calculated?
The brand's record and disclosure
Sensodyne (GSK Consumer Health) does not publish detailed PFAS, heavy metal, or microplastic disclosures for this product. The brand has not faced established recalls for heavy metal contamination or formaldehyde releasers in toothpaste lines. Third-party testing by Consumer Reports and independent labs has not flagged Sensodyne toothpastes for lead, cadmium, or undisclosed allergens in recent years, though comprehensive ingredient transparency beyond label claims remains limited.
How it compares in its category
Sensodyne sensitivity toothpastes occupy a mainstream position, more disclosure than budget brands, but less comprehensive testing documentation than premium or certified natural alternatives. Fluoride toothpastes in this segment (Crest, Colgate Sensitivity, store brands) face identical regulatory oversight under FDA monograph rules. The aluminum tube packaging is standard across most conventional toothpaste brands and carries the same PFAS and leaching questions as competitors.
If you buy it
Store the tube upright with cap tightly sealed to prevent air exposure and minimize any potential for tube degradation or moisture ingress. Toothpaste is a rinse-off product with brief oral contact (typically under 2 minutes), reducing systemic exposure risk for most constituents. Replace the tube once empty or if the cap becomes loose or the tube shows visible dents or damage. No special heating or storage precautions are needed beyond standard room temperature and humidity.
