Crest Complete Scope Outlast Ultra Toothpaste
Lower concern, typical toothpaste formula with no known PFAS triggers, but brand discloses nothing.
Crest Complete Scope Outlast Ultra contains no obvious PFAS-prone ingredients like Teflon-family coating, water-repellent coatings, or nonstick treatments. Toothpaste formulas rarely require PFAS; this one appears to rely on standard silica thickeners and fluoride.

The full breakdown
What it's made of and why it matters
Crest Complete Scope Outlast is an aqueous gel formulation built on a silica-based abrasive system, fluoride (sodium fluoride or stannous fluoride depending on variant), polymers for thickening and coating, and surfactants for cleaning action. The silica particles are food-grade and sized to polish without excessive enamel wear; the polymers (typically cellulose derivatives or acrylates) form a temporary protective layer on teeth. None of these components are known to pose systemic toxicity at the concentrations used in oral products, since toothpaste is spit, not swallowed.
The brand's record and disclosure
Crest (Procter and Gamble) is one of the largest toothpaste manufacturers and has FDA clearance for its fluoride formulations. The brand does not publicly disclose detailed ingredient sourcing or PFAS testing results, which is typical for the oral care industry but represents a transparency gap. No major safety recalls or substantiated safety controversies have been documented for this specific product line. P&G maintains general compliance standards but does not market PFAS-free status or third-party certifications in oral care.
How it compares in its category
This product is mid-market mainstream fluoride toothpaste; chemically comparable to Colgate Total, Sensodyne, and store-brand fluoride gels. The Scope flavoring (mint/cinnamon) and Outlast coating polymer are proprietary but not unusual; similar polymer films are used across brands to extend freshness sensation. It is less specialized than prescription-strength formulas (higher fluoride) or natural/minimalist brands (fewer polymers, no silica abrasives), but also lacks premium claims like whitening enzymes or hydroxyapatite alternatives.
If you buy it
Use only a pea-sized amount for children under 6 to minimize swallowing; supervise brushing. For adults, standard twice-daily use poses no risk. Do not use beyond the product's expiration date, as fluoride potency can degrade and preservative efficacy may drop. Store in a cool, dry place away from direct heat or sunlight to prevent separation or degradation of polymers. If you experience mouth irritation or allergic reaction to mint/flavoring, switch to an unflavored or hypoallergenic fluoride alternative.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fluoride systemic toxicity (ingestion)
At labeled use (pea-sized amount, spit out), fluoride exposure is well below toxic thresholds. Acute toxicity risk only exists with accidental large-volume ingestion by young children; this is why age-appropriate dosing warnings exist on packaging.
Silica inhalation from powder formulations
Crest Complete Scope is a gel, not a powder, so no airborne silica hazard during normal use. Silica in gel form is inert and remains in the paste matrix.
Flavor allergens (mint, cinnamaldehyde, other additives)
Some individuals report oral irritation, contact dermatitis, or allergic reactions to cinnamon compounds or menthol in flavored toothpastes. This is product-specific to the Scope/Outlast variant with added flavorings; unflavored fluoride gels avoid this entirely.
Polymer coating effects on enamel (long-term)
The Outlast polymer film is designed to be temporary and non-adhesive; no established evidence that polymer toothpaste coatings degrade or damage enamel over typical use. However, independent long-term safety data on this specific polymer formulation is not publicly available.
Abrasive wear from silica (enamel erosion)
Silica in standard toothpaste (RDA typically 70-100) is formulated to be safe for daily use and is comparable to other major brands. No elevated abrasion hazard is documented for Crest Complete vs. category standard; wear risk is primarily from acidic foods or acidic reflux, not toothpaste formulation.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
