The differences between the various product lines typically include an additional benefit and for the gentle whitening, it is to whiten your teeth in a safe manner.

Directions for use

The directions are for adults and children 12 years of age and older.

How to use it:

  1. Apply at least a 1-inch strip of toothpaste onto a soft bristle toothbrush.
  2. Brush teeth for at least 1 minute twice a day (morning & evening) and not more than 3 times a day, or as recommended by a dentist.
  3. Make sure to brush all sensitive areas of the teeth.
  4. Minimize swallowing and spit out after brushing.

My comments:

  • The directions say to brush your teeth for at least 1 minute rather than the commonly recommended 2 minutes.
  • Although studies have shown that 3 minutes is even better than 2.
  • They limit usage of the toothpaste to three times a day unless otherwise directed by your dentist. We fully endorse, the best oral hygiene practice of brushing after each meal whenever possible.

The Multi-Action toothpaste comes in a rectangular cardboard box with a cut out in the shape of the pronamel logo to showcase the tube’s cap. It has a white, teal, and blue themed color scheme.

To me, it gives off a simple, clean, and straight to the point product design.

Overall, the initial impression of the packaging is very similar to all of the other pronamel toothpastes that I’ve reviewed. They’re not overly fancy in that they don’t try to distract you with design.

Nonetheless, the aesthetic does appeal to me since I do prefer simplistic designs.

You can find the lot number and expiration date on one of the ends of the box.

What I did notice was that the product box was not sealed with glue or tape. Although that seems to be a common theme with Pronamel, I’ve set to see one that was taped or glued.

The entire contents of the box is a single tube of toothpaste with nothing else inside. There are no additional paper instructions and whatnot.

Objectively, the tube of toothpaste looks very similar to all of the other sensodyne pronamel products that I’ve tried thus far. They really stayed consistent with their design, branding, and image across all of their product lines

As for the dispensing mechanism, it is a plastic squeezable tube with a twist off cap. The twisting is not very deep but there is an audible click towards the end to let you know that it’s securely sealed.

After having tried an abundance of toothpastes, the twist off cap from is not my preferred cap design. In my opinion, the flip cap is much more convenient.

Although I must admit that the biggest benefit of a screw cap design is that it is more secure. It definitely won’t accidentally open if you pack in with your luggage while a flip can may potentially open accidentally.

Last but not least, the way the cap is designed permits the tube of toothpaste to be stored upright in an vertical position.

In my opinion, this helps to keep the bathroom counter more organized especially if you compared to the lay flat type of toothpastes.

My experience

The two most prominent impressions that the multi action toothpaste left on me was it’s incredibly mild mint taste and the glittering paste color.

Aside from that, it left my mouth very clean just like all of the other pronamel toothpastes. It also didn’t foam much but the lathering was still very good.

The pronamel multi action toothpaste has the most interesting color out of all of their products because it glimmers. The paste is white in color owing to the titanium dioxide but is slightly more translucent looking.

It seems like a typical white color but if you look closely, the paste has sparkles and glitters inside of it. The image below is a zoomed in photo.

The mica in the formulation is what gives it the glitter. It is a common ingredient found in cosmetic products like eye shadow and blush.

I’m actually not sure why they added mica to this toothpaste and not their other ones. This is the only pronamel that has it.


It has a very mild mint smell which you do have to focus a little to smell it.


This has to be one of the most neutral tasting toothpastes that I’ve ever used. I could almost describe it as having no taste but with a slight hint of mint.

It was definitely a breath of fresh air since I’ve been brushing my teeth with mint flavored toothpastes about 5-10x per day from doing these reviews. Honestly been getting a little tired of mint.

There is also the fact that the toothpaste I reviewed right before this was the pronamel gentle whitening which had an incredibly strong menthol mint flavor. This toothpaste is the complete opposite of the gentle whitening.


The texture of the multi action toothpaste is solid but feel quite soft when you’re brushing. There is no gritty sensation nor abrasive feeling to it while I was brushing with it. It simply melted into the teeth.

For the most part, pronamel toothpastes are on the lower end with their abrasiveness. They tend to have a low RDA value (relative dentin abrasivity) and that makes them enamel safe.

Last but not least, it holds its shape pretty well even when I invert the toothbrush.

Therefore you don’t have to worry about it sliding off in case you weren’t paying attention while handling your toothbrush. Sometimes it happens when you look away for a second and find the toothpaste in the sink.

That won’t happen with this toothpaste!


Like other pronamel toothpastes, the multi-action does not contain sodium lauryl sulfate so there is very minimal foaming. It uses a more mild surfactant, cocamidopropyl betaine that is less harsh than SLS.

The image above shows the amount of foam that was in my mouth after 2 full minutes of brushing. That amount of foam is without any spitting and without any drooling.

Typically with the very foamy toothpastes, a lot of it would have drooled off onto the sink by the time you’re done brushing. You won’t get that here.

A great perk about the minimal foaming is that it does keep the sink cleaner.


Despite the lack of overwhelming mint, my mouth still felt very clean after I finished brushing. You do still get a tiny hit of spicy tingling if you get it on your outer lips.


This is an anti-sensitivity toothpaste so I did not experience any teeth sensitivity from using it. As a matter of fact, it helps to reduce sensitivity throughout the day.

The Sensodyne brand was made for people with sensitive teeth and I don’t think people without sensitivity even use it.

Pros & Cons


  • Neutral tasting flavor.
  • Prevents cavities (sodium fluoride).
  • Reduces teeth sensitivity (potassium nitrate).
  • SLS-free (maximizes fluoride absorption).
  • Stores upright.
  • Toothpaste sparkles.


  • Cost more than regular toothpaste.
  • Twist off cap.

Does it work?

The two main benefits of using the Pronamel gentle whitening toothpaste is that it can protect the enamel while desensitizing teeth.

Does it work?

Yes, this sensodyne toothpaste does work in regards to those two aspects.

Protects weakened enamel

This toothpaste can help rebuild and restore weakened enamel because it contains sodium fluoride while excluding SLS. These two combinations help maximize the efficacy of the anti-cavity effect.

Ingredients benefits:

  • Sodium fluoride. The inclusion of fluoride helps to enhance tooth remineralization, inhibit demineralization, and strengthen the enamel. This is the creme de la creme for getting stronger teeth.
  • SLS-free. Studies have shown that sodium lauryl sulfate will interfere with the fluoride adsorption for teeth. The SLS will bind to the fluoride thus reducing the bioavailability that can be used for strengthening teeth.

Most toothpastes do use SLS in their formulation for more effective cleaning of the teeth. However, the downside is that it decreases the fluoride efficacy.

A core principle for the pronamel toothpastes is the lack of SLS which boosts the effectiveness of fluoride. That is the reason why they can rightfully state that they are the enamel protection specialists when it comes to dentifrices.

Reduces sensitivity

As with most pronamel toothpastes, it can reduce teeth sensitivity because it contains the desensitizer, potassium nitrate. This ingredient will depolarize the tooth nerve thus numbing it.

That means the tooth can still be stimulated but you just won’t feel any discomfort. An analogy would be if you were numb from getting novocaine.

How potassium nitrate desensitizes teeth:

  1. Brushing with it will supply an overabundance of potassium ions to the nerve.
  2. Excessive K+ will reverse the extracellular concentration gradient.
  3. Reversal of the gradient prevents action potential propagation.

The end result is a reduction in dentin hypersensitivity and an improvement in your quality of life. It’ll help you enjoy that cold glass of water once more.

How long it takes to work

For sensitivity reduction using potassium nitrate, the full desensitizing effect may not be apparent until 12 weeks later. Although you will begin to notice improvements within the first few days.

Studies have shown that symptoms gradually improved week over week with twice daily brushing. The relief from sensitivity continued to improve all the way up to the 12th week.

Therefore you should start to notice an improvement in symptoms after 1-2 weeks of use. Although you need to continue using it for at least 12 weeks to see its full desensitizing effect.

Also if you stop using the toothpaste, the desensitizing effect will wear off so you shouldn’t stop using it even after achieving its full effect.

How it compares to other pronamel toothpastes

For the most part, most pronamel toothpastes are very similar to one another. The bulk or core of their ingredients are identical but with a handful of exceptions.

Although from a personal use perspective, the biggest distinguishing feature about the multi-action dentifrice is its very neutral tasting mint flavor. I would almost describe it as having no flavor but with a tiny hint of mint.

It’s good to have that variety because sometimes you just don’t want anything too flavorful.


Overall, I would rate the Sensodyne Pronamel multi-action as a good daily toothpaste to use for protecting your teeth

  • Its formulation maximizes the fluoride efficacy thus protecting the enamel from acid attacks.
  • It also helps reduce and alleviate sensitivity from cold and acidic foods/beverages.

In summary, their primary focus is on protecting your teeth and reducing teeth sensitivity. If those are your two biggest oral health concerns, we’re fairly confident that this dentifrice would fit your needs.

Nonetheless, that concludes the review of the pronamel multi-action toothpaste by a dentist!
