Crest Cavity Protection Regular Paste Toothpaste

Active anticavity ingredient (0.15% w/v fluoride ion). Classified by The Lancet (2014) as a developmental neurotoxicant; chronic ingestion linked to dental fluorosis, lowered IQ in children (NTP 2024 monograph), and thyroid suppression.

Harsh anionic surfactant responsible for the foaming action. Documented trigger for recurrent aphthous (canker) ulcers in clinical studies (Herlofson & Barkvoll 1996, Healy et al. 1999); strips the protective oral mucin layer; common contact irritant. Cleaner toothpastes use coconut-derived alternatives.

Whitening pigment. Banned as a food additive in the European Union since 2022 after EFSA concluded it cannot be considered safe due to genotoxicity concerns from nanoparticle fractions. IARC Group 2B (possibly carcinogenic to humans) when inhaled. Lead Safe Mama 2025 also implicates titanium dioxide as a likely source of the lead contamination detected in this product.

Synthetic petroleum-derived dye (Brilliant Blue FCF). Banned in several European countries; flagged by the Center for Science in the Public Interest as a hyperactivity trigger in children. No nutritional or oral-health justification.

Strongly alkaline pH adjuster (also used as an industrial degreaser). Repeated exposure can disrupt enamel pH balance and irritate soft oral tissue.

Proprietary flavor blend. Can hide dozens of synthetic aroma chemicals and phthalate carriers under FDA trade-secret rules.

Phosphate additive — mineral-balance concern for frequent consumers.

Synthetic sweetener used purely for taste. Associated with gut microbiome disruption (Suez et al. 2014); was on the U.S. NTP carcinogen list until 2000; safety remains controversial.

Sugar alcohol humectant; non-cariogenic.

Solvent base.

Standard mild toothpaste abrasive — safe at typical use.

Plant-derived thickener (carboxymethylcellulose). Inert and safe in topical oral care.

Synthetic acrylic-acid polymer used as a thickener; considered inert in oral care formulations.
