Sensodyne Vs Pronamel: Differences & Similarities

Written & Reviewed by Dr David Chen

Sensodyne toothpaste and pronamel toothpaste are both made by the same manufacturer, Haleon. As a matter of fact, the pronamel is actually a subdivision of sensodyne which is why it’s full name is “Sensodyne Pronamel.”

Both pronamel and sensodyne were made for people who suffer from chronic teeth sensitivity. The main conceptual difference between the two is that the sensodyne is marketed towards sensitivity only while the pronamel is sensitivity plus strengthening teeth.

Pronamel vs Sensodyne toothpaste

Key differences:

  • Sensodyne is made for sensitive teeth.
  • Pronamel is made for sensitive teeth with enamel repair.

Those two key differences are based on the official statements by Sensodyne. However, if you compare the two dentifrices closely, there are much more differences than that. Although the distinctions they’re mentioning above aren’t quite as different as you may think.

Our purpose is to compare all of the features between pronamel vs sensodyne.

  • Which one is better at fighting tooth decay?
  • Which one is better for keeping your gums healthy?
  • Is one better at reducing teeth sensitivity?
  • Is one better at whitening your teeth?
  • Do they all have SLS?

Table Comparison

Below is a table comparison of the features between sensodyne vs pronamel toothpaste.

Both of these toothpastes’ effects on your oral health aren’t as drastic as you may have though. They mostly do the same things but their efficacy in each feature may be slightly different.

In the next section we will dive deeper in the nitty gritty details.

Cavity prevention

Sensodyne and pronamel toothpastes have anti-cavity properties because they both contain fluoride. Evidence of that can be seen on their box label which clearly states that their purpose is to prevent tooth decay.

Although their purposes may be similar, the type of fluoride they use are different.

  • Sensodyne mostly use stannous fluoride (SnF2) which is fluoride that is bound to tin.
  • Pronamel only uses sodium fluoride (NaF) which is fluoride that is bound to sodium.

The only cavity prevention and enamel strengthening agent in those two types of fluoride is the fluoride ion itself. The stannous and sodium ions are merely stabilizers to help deliver the fluoride to your teeth.

Therefore, in that regard both of these anti-cavity agents should theoretically have a similar efficacy. However, research has shown that SnF2 does come with other effects which may have additional benefits for your oral health.

Sodium fluoride vs Stannous fluoride

Below are the differences between NaF vs SnF2 and as you can see, they share a lot of similarities but the stannous version does come with extra perks.

NaF benefits:

  • Inhibition of demineralization
  • Enhancement of remineralization
  • Inhibition of bacterial activity in plaque

SnF2 benefits:

  • Inhibition of demineralization
  • Enhancement of remineralization
  • Inhibition of bacterial activity in plaque
  • Anti-bacterial (bactericidal & bacteriostatic)
  • Decreases teeth sensitivity
  • Improves gum health

It is due to the reasons above that stannous fluoride toothpastes cost more than their sodium fluoride counterparts.

Gum health

Both the pronamel and sensodyne toothpastes can help prevent gum disease because they help remove plaque and the fluoride has antibacterial properties. Brushing with either one will improve the conditions of your

However, the stannous fluoride within sensodyne may have a slight edge in efficacy for keeping your gums healthier. Research have shown that SnF2 repressed the bacterial population more than other types of fluoride.

Once again, that is why the stannous versions of toothpaste do come with a price premium.

Teeth sensitivity

The difference between pronamel vs sensodyne in decreasing teeth sensitivity has to do with the desensitizing agent that they use. Yes, using either of them should help alleviate your discomfort when you drink cold beverages or when you breathe in cold air.

Type of desensitizer in each toothpaste:

You’re probably thinking, stannous fluoride again?! Yes, stannous fluoride is a proven teeth desensitizing agent. Studies have shown that there were marked improvements in dentinal hypersensitivity when brushing with it compared to a placebo.

These toothpaste desensitizers work via different mechanisms and we don’t particularly believe that one is superior to the other. People with sensitive teeth will react different to different products. If one works better for you stick with it, if it doesn’t you may want to try the other one.

Desensitizing mechanisms:

In our opinion, whichever sensitive toothpaste that works better for you is the best one for you! Although you do need to use each one for at least a few weeks to see its full effects.

Teeth whitening

You will most likely find the label whitening on both the pronamel and sensodyne toothpastes. As a matter of fact, it’s quite rare to find a non-whitening toothpaste.

Yes, both toothpastes can whiten your teeth by mechanically abrading away stains but they will not whiten them via chemical bleaching. That is the major difference between professional teeth whitening and whitening toothpastes.

Toothpaste whitening vs professional whitening:

  • Sensodyne and pronamel toothpastes use abrasives to scrub away stains on the exterior surfaces of your enamel.
  • Professional whitening uses hydrogen peroxide to chemically oxidize stains on the exterior and interior surfaces of your enamel.

The best analogy we can think of for abrasive whitening is when you scrub a dried stain away from a dinner plate. On the other hand, chemical oxidation is when you use bleach on a wine stained white t-shirt.

Exception: There are whitening toothpastes which do contain peroxide such as the colgate optic white pro series toothpaste.

Can whitening toothpaste damage enamel?

Since whitening toothpastes use abrasives which you scrub your enamel with, if they are too abrasive they can be harmful. Fortunately for you, pronamel and sensodyne toothpastes are relatively low on the abrasiveness scale for whitening toothpastes.

Toothpaste RDA chart

The chart above shows various toothpaste abrasivity and yes, the sensodyne product lines are all within safety limits.

Sodium lauryl sulfate (SLS)

None of the pronamel toothpastes use sodium lauryl sulfate while most sensodyne toothpastes do not use SLS. There are a select few product lines within sensodyne which do contain it so you do need to read the labels carefully.

Sensodyne toothpastes with SLS:

Sodium lauryl sulfate is relatively safe to use because the FDA has even cleared it to be used as a food additive. Most of the fear about its safety has been overblown.

Yes, it is a very potent surfactant (detergent/soap) so it may be too harsh for some people’s liking when used in their mouth. That is understandable and if that is the case, it is your personal preference whether you want to use it or not.

Verdict – Which one is better?

In our opinion, there isn’t an absolute best meaning that sensodyne isn’t necessarily better than pronamel nor is the vice versa true.

Most people choose to use their products because they are suffering from teeth sensitivity. Unfortunately certain people respond better to certain desensitizers. Therefore, we encourage you to try both of them to see which one alleviates your discomfort more.

Which ever one can reduce your teeth sensitivity the most, that would be the best one for you.
