The 10 Best Enamel Toothpastes

If coffee, soda or citrus has left your teeth sore and a little see-through at the edges, Sensodyne Pronamel Intensive Enamel Repair is a sensible first tube. It pairs sodium fluoride, which helps harden acid-softened enamel, with potassium nitrate, which is meant to calm sensitive nerves over a few weeks of brushing. The paste is gentle on teeth and leaves out the detergent that makes most pastes foam. Its repair claims rest on the maker's own studies.

Crest Gum & Enamel Repair holds a rare distinction: the American Dental Association's Seal covers its help against enamel erosion from acidic food and drink, along with cavities, gingivitis and sensitivity. Its stannous fluoride also works on the plaque germs behind puffy, bleeding gums. Crest now sells the formula in a navy carton called Gum & Enamel Restore. Stannous fluoride can leave light brown stains on the surface of teeth, though steady brushing usually keeps them away.

For sensitive teeth on a budget, Colgate Sensitive Enamel Health uses the pairing most sensitivity pastes rely on: potassium nitrate to quiet twinges and sodium fluoride to guard against cavities and help re-harden enamel. It comes in big tubes sold three to a pack, so one order lasts a household a long while. The peppermint is soft rather than sharp. Relief builds over a couple of weeks of twice-daily brushing, and the paste makes no gum-care claim.

Built around acid wear, Colgate Total Enamel Strength is meant to re-harden the weak spots that coffee, soda and wine leave behind. Its stannous fluoride is the kind that fights plaque germs and eases sensitivity while it protects against cavities, so one tube covers a lot of ground for little money. The peppermint is bright and clean. This version is new, so it has a short track record, and its enamel claims come only from Colgate's own research.

Sore teeth and a tight budget meet in Crest Sensitive & Enamel Shield, a stannous fluoride paste that takes on twinges, cavities, plaque and gum inflammation from one tube. Crest says it guards enamel too, though that claim rests on its own studies. It foams like a regular paste and has a familiar mint taste. The label says to see a dentist if pain lasts past four weeks, and stannous fluoride can leave faint stains.

Sensodyne Pronamel Daily Protection is the everyday member of the Pronamel family, made for people who want a fluoride paste that stays easy on acid-worn teeth twice a day. It is low in abrasion, skips sodium lauryl sulfate and adds potassium nitrate for teeth that twinge. Buying it in a three-pack keeps the cost per tube down. Haleon publishes less detail about this formula, and it makes no claim to help gums.

Coffee and tea drinkers who want brighter teeth without scrubbing at their enamel can look at Sensodyne Pronamel Clinical Whitening. It lifts surface stains with a polishing system Haleon says is safe for enamel, while fluoride and potassium nitrate work on acid wear and sensitivity. It replaced the older Gentle Whitening paste. It removes stains but won't change the natural shade of teeth, and it costs more per tube than ordinary toothpaste.

People who would rather skip fluoride often land on Boka Nano-Hydroxyapatite, which uses a man-made form of the mineral enamel is built from. Early studies suggest it can help remineralize teeth, but the evidence is still thin, and it carries no approved cavity-prevention claim. The paste is light on mint, foams little and leaves out sulfates and dyes. Dentists generally advise keeping fluoride in the routine, so treat it as an add-on, not a swap.

Made in Italy, Biorepair Intensive Night Repair is a fluoride-free paste for the last brush of the day, when saliva slows and acid has more time to work on teeth. Coswell, its maker, says a zinc-rich form of the tooth mineral hydroxyapatite coats and smooths worn spots overnight. The carton is printed in Italian without a U.S. drug label, and like other fluoride-free pastes it has no approved cavity claim, so pair it with fluoride.

Arm & Hammer Enamel Defense keeps things simple and cheap: sodium fluoride for cavities and baking soda to polish away surface stains. It comes two tubes to a pack, and recent cartons carry the name Bright & Strong for the same formula. The salty baking soda taste won't suit everyone. There's no sensitivity ingredient, and its enamel claim rests on fluoride, which nearly every regular toothpaste already has.
