Sensodyne True White Toothpaste Review

A white smile is one of the most desired physical attributes in the USA, but often great results come with less attractive side effects. Especially for those with sensitive teeth, Sensodyne True White Toothpaste contains a unique formula that combines teeth whitening with sensitivity protection for a pain-free whitening solution (view on Amazon).

88% of Americans desire a whiter smile, so it’s no surprise that whitening toothpastes can be found everywhere. However, many teeth whitening products can lead to enamel erosion. This, in turn, can expose the soft inner tissue of the teeth which can result in significant tooth sensitivity.

However, they can be very abrasive and many teeth whitening products lead to enamel erosion. This, in turn, can expose the soft inner tissue of the teeth which can result in significant tooth sensitivity.

With this in mind, it’s no surprise that many households switch their generic whitening toothpaste for sensitivity-relief products.

Luckily, Sensodyne True White Toothpaste offers a solution. Specifically, it uses a formula that’s 10 times less abrasive than other whitening toothpastes.

Here, we look at the 5 things you need to know before deciding if Sensodyne True White Toothpaste is a good fit for you.

But first: what makes a good toothpaste?

A good toothpaste should remove plaque. Importantly, it should also avoid damaging the enamel.

The ADA states that a good toothpaste should:

  • Contain at least 1000ppm fluoride.
  • Contain only artificial sweeteners.
  • Have a relative dentin abrasivity (RDA) of less than 250.
  • Allow you to maintain an effective oral hygiene routine.*

*Ultimately, the ideal toothpaste is one that works long-term. Factors that influence this include taste and texture.

Makes you want to use it? Available in two flavors: Extra Fresh and Mint. Comes in a wide tube, which stands. Lotion-like texture.

When brushing twice daily, Sensodyne True White both whitens and relieves teeth sensitivity. Importantly, potassium nitrate relaxes the nerves inside the teeth, relieving hypersensitivity. Sodium tripolyphosphate also acts as a binder. This lifts stains from the teeth’s surface.


  • Whitens teeth and lifts stains.
  • Designed to target sensitivity.
  • Low RDA level.
  • Leaves a protective layer.
  • Two gentle flavor options.


  • Unlikely to produce speedy results.
  • Difficult to use with electric toothbrushes.

Sensodyne True White Toothpaste targets sensitivity by using a low RDA formula. This means that, unlike some other whitening toothpastes, it shouldn’t cause damage to the enamel or cause further sensitivity. Potassium nitrate relaxes the nerve endings inside the tooth, which also reduces sensitivity. Additionally, the toothpaste is low cost compared to other products.

Besides that, the active ingredients target sensitivity and stain-removal. However, it is worth noting that Sensodyne does not contain peroxide. This is a popular bleaching agent. As a result, Sensodyne is unlikely to produce drastic results. However, it will lift surface stains. Sensodyne recommends applying a 1” strip for best results. This can prove difficult when using an electric toothbrush because of its small head size.

5 things you need to know about Sensodyne True White Toothpaste

1.) Does it work?

Sensodyne True White Toothpaste has two goals: to whiten teeth and minimize sensitivity (view details).

Tooth discoloration occurs on two common levels: extrinsic and intrinsic. Sensodyne True White, like many whitening toothpastes, targets superficial extrinsic stains. Examples include tea, coffee, and chocolate.

There are 3 key ingredients that make this toothpaste work:

  1. Sodium fluoride is a key ingredient in most toothpastes. It is especially useful in protecting enamel by reducing demineralization.
  2. Sodium tripolyphosphate whitens by binding to and removing extrinsic stains.
  3. Potassium nitrate reduces sensitivity by relaxing the nerves within the teeth’s dentin layer.

> How soon can I expect results?

By avoiding the use of peroxide, results are unlikely to show before 2 weeks of use. This also depends on correct use—namely, brushing with a 1” strip of toothpaste twice daily.

> How long will results last?

Results vary from person to person. With consistent use, you  can expect long-term results. However, Sensodyne lifts surface stains rather than bleaching the teeth. As a result, the toothpaste will not exceed natural whiteness. Additionally, refraining from stain-inducing food and drink such as coffee and tea can prolong results.

2.) Will Sensodyne True White Toothpaste damage my teeth?

A good toothpaste is free from products that are detrimental to dental hygiene. This includes sugar, which leads to tooth decay. Instead, Sensodyne True White uses saccharin to produce flavor, while inhibiting tooth decay. While an RDA of 150-250 is considered dangerous, Sensodyne has an RDA level of only 13, making it less abrasive than other products.

3.) Does Sensodyne True White Toothpaste protect your teeth?

The ADA recommends that a toothpaste should have a fluoride level of at least 1000ppm to effectively protect teeth. Sensodyne True White contains a fluoride level of 1450ppm. As a result, Sensodyne is effective in reducing demineralization, which can lead to severe tooth decay.

4.) How does Sensodyne True White Toothpaste taste?

Sensodyne True White Toothpaste is available in two flavors: Extra Fresh and Mint. Both are subtle to reduce burning sensations caused by strong flavors.

5.) Is there something better?

This product is suitable for those with sensitive teeth who are conscious about their smile. It reduces discoloration while protecting teeth from damage.

For those less prone to sensitivity and looking for more extreme results, peroxide-based whitening products such as Crest 3D Whitestrips With Light. These will produce quicker and more visible improvements. However, they also tend to be more expensive as they contain active bleaching agents.

For child-friendly flavors, Sensodyne Pronamel Toothpaste features a gentle mint flavor. It also protects teeth against acidic food and drink.

Sensodyne True White Toothpaste summary

In sum, Sensodyne True White Toothpaste can lift stains while protecting teeth from hypersensitivity. This makes it suitable for those prone to irritation but still invested in a whiter smile.

Due to the absence of bleaching agents, Sensodyne takes approximately 2 weeks of use to attain visible results. It is also a cost-effective alternative to abrasive formulas (view details).

The use of fluoride guarantees a natural white smile and notably reduced discoloration. Used with a Sensodyne mouthwash, Sensodyne True White can produce lasting effects for whitening and protection against sensitivity.
