ProNamel™ is a toothpaste marketed by Sensodyne® that provides protection against enamel erosion and tooth sensitivity. It works by strengthening tooth enamel and preventing future wear from the acids found in certain foods and beverages. ProNamel™ also provides the benefits generally expected in a toothpaste: removing plaque, freshening breath, and preventing cavities.

Many foods and drinks, such as fruits, vegetables, soda, coffee, and sports drinks, are very acidic, as determined by their low pH levels. The pH scale is simply a measure of the acidity of a substance, as compared with pure, neutral water (pH seven). Coffee has a pH of about four, and citrus fruits such as oranges have an even lower pH, about three. Substances with pH levels this low are considered very acidic, and frequent exposure can soften or even deteriorate the surface enamel of teeth, making them more susceptible to excessive wear, chipping, and sensitivity to hot and cold. While ProNamel™ is unable to restore teeth to their previous condition, it is effective in strengthening existing enamel.

The active ingredients of the toothpaste are sodium fluoride and potassium nitrate. Sodium fluoride has been proven effective in hardening the outer layer of enamel on teeth. In turn, the teeth become better protected against acids and future decay. The potassium nitrate found in ProNamel™ supposedly works to reduce existing tooth sensitivity, although its effectiveness has not been verified in clinical trials.


While no negative side effects have been associated with using ProNamel™, it does contain a controversial artificial sweetening agent known as saccharin. There have been concerns about the correlation between saccharin ingestion and the frequency of cancer in laboratory animals. There is no proof of a causal relationship between cancer and saccharin, however, and it is generally assumed that small doses are harmless to humans.

Sensodyne® recommends that ProNamel™ be used twice a day in conjunction with common oral hygiene practices, such as regular flossing and periodic trips to the dentist's office. They also suggest that people who suffer from sensitive teeth and enamel loss limit their consumption of acidic foods and beverages. People suffering from severe tooth decay or intense sensitivity problems should seek the guidance of a dentist before opting for an over-the-counter toothpaste such as ProNamel™.

Fluoride is the waste product from the aluminum and plutonium refining process. It is also used as rat poison. Toothpaste contains 1450 parts per million. Would you knowingly give yourself or your children cynanide? Then why give them this poison?

They do not say the fluoride hardens the tooth enamel. They say it is the potassium nitrate.

O.K., let me see if I have this right. There is no magic ingredient in this toothpaste that makes it any different than any other toothpaste to harden enamel since every major toothpaste brand also contains flouride.

My father is a dentist and he said unless you have sensitive teeth, there is no reason whatsoever to use this over any other brand of toothpaste. This was strictly a branding device meant to sell the toothpaste, and while they are not lying about the product's efficacy or ingredients, they conveniently neglect to mention that it is absolutely nothing new!

Sneaky, sneaky. Don Draper must have pulled that subtle little rebranding idea out of his magic hat for the folks over at corporate Sensodyne! I admit I was fooled. I bought a tube before figuring it out.

Pronamel mouthwash contains one of the highest concentrations of fluoride on the market right now (450ppm) as opposed to only (225ppm).

Also, pronamel toothpaste doesn't contain SLS which is the detergent that makes other toothpastes foam up and is less abrasive to sensitive teeth. Some people have SLS allergies too, so it's good for them.

Not sure it does much for sensitivity as it relies on potassium nitrate and there is lacking evidence for its actual benefit. Sensodyne's other toothpaste brands though, rely on the same theory and they seem to work for people with sensitive teeth.

Sensodyne's original range doesn't work for me. However, the newer Sensodyne rapid relief and colgate's pro relief do.

The brief contact with fluoride while brushing is minimal, so not doing much to counter the effects of all the food and drinks in your mouth every day.

So, since sensodyne pronamel has exactly the same fluoride content of most other popular mainstream toothpastes, not advertised as enamel protecting, can we assume that the pronamel moniker is just a con?
