Pronamel Toothpaste Gentle Whitening vs Tom’s of Maine Antiplaque and Whitening Fluoride Free Toothpaste, Peppermint, 2 Pack, 4.5 Oz: which is safer?

Where these two actually differ

• We flag Fluoride toxicity (systemic ingestion) and Allergic contact dermatitis from flavorings or thickeners on the Sensodyne and not on the Tom's of Maine.
• We flag Heavy metals in mineral pigments or abrasives and Fragrance allergens from essential oils on the Tom's of Maine and not on the Sensodyne.
• The Sensodyne is Aqueous gel base with calcium compounds and abrasives (silica/alumina); typical toothpaste formulation where the Tom's of Maine is toothpaste base, mineral silica, essential oils, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Tom's of Maine is the one to buy.
