Sensodyne Toothpaste Review

This article takes a look at the Sensodyne range of toothpastes – and the range is big. Here we look at what differentiates each product to help you find the one that best matches your needs.

Toothpaste matters. Your oral hygiene regime may be simple or complex, but toothpaste is at its very core. If a toothpaste is not a good match for your needs it can create or worsen problems and make brushing a chore. Find the right match though, and brushing can become a pleasurable ritual.

This article will:

  • look at what causes sensitivity;
  • examine what makes Sensodyne unique;
  • overview the Sensodyne range to help you identify which one might suit you best;
  • review four popular Sensodyne products;
  • provide an overall summary of the brand.

What causes Sensitivity?

According to the American Dental Association one in eight of us experience tooth sensitivity.

It’s caused when tooth enamel becomes worn or damaged and the dentine underneath is exposed. Dentine contains microscopic channels or tubes. Once exposed these channels can carry sensations like heat or cold to the nerve in the center of the tooth. This is experienced as a sharp pain.

It can happen due to:

  • Over vigorous brushing
  • Abrasive toothpaste
  • Gum disease and gum recession
  • Too much acidic food
  • Genetic predisposition.

What makes Sensodyne unique?

Quite simply it’s the number one professionally recommended toothpaste for those with sensitive teeth.

Sensodyne are both pioneers and leaders in the world of tooth sensitivity. They’ve been in the business of relieving pain caused by sensitivity and protecting teeth for over half a century.

Their vision, quite simply, is to create “a future where every life is sensitivity-free”.

This matters because if your oral hygiene regime is painful, you won’t rush to brush. You may even avoid it. Not taking care of your oral health could not only spoil your smile, but studies show it could impact on your overall systemic health.

What are my options?

Lots. Whatever your specific priorities are – whitening, repairing vulnerable areas, fresh breath, enamel care, deeper cleaning… You name it, Sensodyne have you covered.

As you can see, the choice is wide. To help you decide, we provide short reviews for five of the most popular and versatile Sensodyne products below.

Sensodyne Pronamel Gentle Whitening

The main aim of this toothpaste is to strengthen tooth enamel and protect it against the effects of acid attack.

Acids contained in everyday food and drink attack tooth enamel, stripping it of minerals and thinning it. This may lead to exposure of the sensitive yellow dentine underneath, one cause of yellowing teeth and the main cause of pain and sensitivity.

Minerals naturally found in saliva slowly help to restore the ph balance in your mouth and remineralise your teeth.

Sensodyne Pronamel is formulated to ensure that the fluoride it contains, as well as the minerals in your saliva, are more efficiently absorbed and retained by tooth enamel.

Sensodyne Pronamel gentle whitening helps to restore natural whiteness by hardening and strengthening tooth enamel, rather than by polishing teeth to lift stains. It also contains titanium dioxide which is a bright white pigment that refracts light and makes teeth look whiter for a limited time.


  • #1 dentist recommended product for strengthening & protecting tooth enamel
  • Contains fluoride to protect against decay
  • Helps to restore natural whiteness
  • Low abrasivity
  • Sodium Lauryl Sulphate free


  • Not specifically designed to lift stains
  • Disputed concerns about the use of Titanium Dioxide
  • A little more costly than regular toothpaste

This toothpaste is suitable for anyone with sensitivity and thinning enamel which may be causing yellowing teeth.

Multi pack options are the best way to save money on this product.

Sensodyne Pronamel Gentle Whitening Ingredients

Active: Sodium Fluoride (1450 ppm Fluoride)

Inactive: Aqua, Sorbitol, Hydrated Silica, Glycerin, Potassium Nitrate, PEG-6, Cocamidopropyl Betaine, Aroma, Titanium Dioxide, Xanthan Gum, Sodium Saccharin, Sodium Fluoride, Sodium Hydroxide, Limonene, Potassium Nitrate 5% w/w.

If your teeth are stained due to smoking or the consumption of products such as red wine, tea or coffee, this particular Sensodyne Toothpaste may not be the right one for you. Try True White Mint (see below) or Sensodyne Pronamel Strong and Bright.

Sensodyne Repair and Protect

The aim of this toothpaste is seek out and repair weakened areas of the teeth where the dentine may be exposed. Dentine contains tiny tubes that can carry sensations to the nerves. This is what causes pain and sensitivity.

Sensodyne Repair and Protect uses a patented formula that combines with water and saliva to form a protective coating. This coating crystallizes to form hydroxyapatite, a substance similar to the minerals naturally found in teeth. It works to fill and cover the tubes in dentin to stop sensations reaching the nerve.

The patented formula, known as Novamin, combines fluoride with calcium, sodium, silica and phosphorus. So as well as relieving sensitivity the toothpaste protects teeth from decay and acid erosion by strengthening tooth enamel.


  • Contains fluoride to protect teeth
  • Reduces sensitivity.
  • Clinically proven to repair damage if used as directed
  • Freshens breath.


  • Surprisingly high relative dentin abrasivity (RDA) of 104.
  • Disputed concerns about the use of Titanium Dioxide
  • Contains Sodium Lauryl Sulphate which can be an irritant.

This product is aimed at those with particularly sensitive teeth. However, if you have severe damage, Sensodyne ProNamel has an RDA of only 34 which makes it much gentler on tooth enamel.

Sensodyne Repair & Protect offers a whitening value pack and a 4-pack of NovaMin Repair & Protect.

Sensodyne Repair & Protect Ingredients

Active: Stannous fluoride.

Inactive: Glycerin, PEG-8, hydrated silica, pentasodium triphosphate, sodium lauryl sulfate, flavor, titanium dioxide, polyacrylic acid, cocamidopropyl betaine, sodium saccharin.

Sensodyne Full Protection plus whitening

As its name suggests, this is an all round product which offers gum protection, fresh breath, plaque control, enamel strengthening, relief from sensitivity and whitening.

The active ingredients in Sensodyne Full Protection with whitening are Fluoride and Potassium nitrate. The potassium nitrate works to block pain signals whilst the fluoride strengthens tooth enamel, helping to build up protection against sensitivity.

To whiten teeth, hydrated silica is used to polish teeth and lift stains. Additionally, titanium dioxide is used. This is a bright white pigment which refracts light and makes teeth appear whiter.


  • Potassium Nitrate reduces sensitivity
  • Contains fluoride
  • Fights plaque build up and promotes healthy gums.
  • It whitens teeth by removing surface stains.


  • Contains Sodium Lauryl Sulphate
  • Disputed concerns about the use of Titanium Dioxide
  • High abrasivity (107)

Sensodyne full protection is aimed at those with sensitive teeth who want an all round product.

The toothpaste is available in a value pack of four with a subscribe and save option to save even more money.

Sensodyne Full Protection Ingredients:

Active Ingredients: Potassium Nitrate (5%) (Antihypersensitivity), Sodium Fluoride (0.145% w/v Fluoride Ion) (Anticavity)

Inactive Ingredients: water, hydrated silica, sorbitol, glycerin, pentasodium triphosphate, PEG-8, flavor, titanium dioxide, cocamidopropyl betaine, sodium methyl cocoyl taurate, xanthan gum, sodium hydroxide, sodium saccharin, sucralose

If you have really sensitive teeth, Sensodyne ProNamel has an relative dentin abrasivity of only 34 which makes it much kinder to tooth enamel.

True White

Sensodyne True White Toothpaste has two aims: to reduce sensitivity and whiten teeth.

There are 3 key ingredients that make this toothpaste work.

Potassium nitrate helps to reduce sensitivity by blocking pain signals that occur when exposed dentin reacts to sensations like heat or cold.

Sodium fluoride then protects and strengthens tooth enamel, which will ultimately reduce sensitivity.

Lastly to whiten teeth, Sodium tripolyphosphate binds with and removes stains. Sensodyne True White toothpaste does not contain any bleaching agent so it is unlikely to produce fast, dazzling results.


  • Potassium Nitrate reduces sensitivity
  • Contains fluoride which strengthens enamel
  • Whitens teeth and lifts stains.
  • Low abrasivity level of only 13 – 10x less abrasive than many whitening toothpastes
  • Leaves a protective layer.
  • Two gentle flavor options.


  • Unlikely to produce speedy results.

Sensodyne True White Toothpaste is aimed at anyone with sensitive teeth who wants to brighten their smile.

Multipacks in both True White flavors are available, as well as travel-sized packs.

Sensodyne True White Ingredients

Active ingredients: Potassium nitrate, Sodium fluoride.

Inactive ingredients: Sorbitol, water, glycerin, hydrated silica, pentasodium triphosphate, PEG-8, flavor, titanium dioxide, sodium methyl cocoyl taurate, cocamidopropyl betaine, xanthan gum, sodium hydroxide, sodium saccharin.

If brightening your smile is a key priority you may want more dramatic results. Consider using Crest 3D White Whitestrips Gentle Routine LINK. These will give you more dramatic results whilst still catering for your sensitivity.

Sensodyne toothpaste conclusion

Sensodyne is the number one professionally recommended toothpaste for those with sensitive teeth. Its vision is to create “a future where every life is sensitivity-free”.

This matters because if your oral hygiene regime is painful, you won’t enjoy brushing and may try to avoid it.

There is a wide range of products in the Sensodyne brand, each one meets slightly different needs.  In our view, due to its low abrasivity, the ProNamel range is definitely worth considering.

Sensitivity may be an indicator of a more serious underlying problem so you should discuss it with your dentist. She or he may then be able to help you identify which Sensodyne product is the right match for you.


Does Sensodyne contain triclosan?

Glaxo Smith Kline claim none of their products contain Triclosan.

What is the difference between Sensodyne Repair and Sensodyne Pronamel?

ProNamel® products are engineered to help protect teeth from the effects of acid erosion.

Repair products are designed to fill and cover the tubes in exposed dentine in order to block pain signals.

Both products contain stannous fluoride, which helps to remineralise teeth and strengthen enamel.

What does Alpine Breeze taste like?  Is it minty?

Yes, it is mint flavoured but not strong.

Are these products tested on animals?

Yes, Glaxo Smith Kline products are not cruelty free.

How do desensitizing toothpastes work?

If enamel becomes worn, sensitive dentin can be exposed. Different Sensodyne products deal with this in different ways. Products with potassium nitrate soothe the nerves inside the tooth and block pain signals. Products with Novamin fill and block the holes or tubes in exposed dentin. All products (except Sensodyne Original) contain fluoride which builds a strong restorative layer over the exposed dentin to create a barrier to pain trigger such as heat or cold.

How long will it be before I notice less sensitivity?

Clinical studies show that Sensodyne will relieve tooth sensitivity within four weeks if used as directed.

Are there any fluoride free Sensodyne products?

Only Sensodyne Original is fluoride free.

What is the Relative Dentin Abrasivity (RDA) for Sensodyne toothpaste?

Although all Sensodyne toothpastes comply with the American Dental Association (ADA) standards for RDA, there is a wide variation amongst them. Values range from 35 to 140.

  1. I would like to know why you had to discontinue your pink Sensodyne toothpaste. I have been using it for such a long time. I have bought sensory experience Rapid and I don’t like it one bit, it tastes disgusting. I will be trying a different brand & tosee if I can find a better tasting toothpaste.

    • Hi Janice. Thanks for your comment. We just review toothpastes on this site so we can’t help with this one! You can contact GSK (the manufacturers) by email on Good luck, I hope they can answer your question and maybe suggest an alternative.

    • Hi Keith, sorry for the delay in responding to your question. Sensodyne Toothpaste is made by GlaxoSmithKline which is a US company. I’m not sure where it is actually made but it is available on Amazon to the US market. Hope that helped!

  2. In my 60 years of life I’ve never experience sensitivity for hot or cold. But I decided to try Sensodyne toothpaste and how I regret it now I can’t eat hot or cold they bother me like never before.

    • Hi Maria, Thanks for your comments. I’m sorry to hear that Sensodyne Toothpaste seems to have achieved the opposite effect in your case. We all have different tolerances and sensitivities to different substances. I guess there is just something in the Sensodyne mix that doesn’t agree with you. I hope that things are back to normal now.
