Uncle Harry’s toothpaste review

Uncle Harry's Spearmint Remineralizing Toothpaste | Natural Whitening Toothpaste Freshens Breath &...

More Info

Uncle Harry’s Toothpaste was formulated by Uncle Harry following a period of painful and acute gum infection. When conventional dental procedures failed to reverse his symptoms, Harry turned to ancient herbal medicine. The result is an all-natural toothpaste based on centuries of ancient wisdom which not only helps to cure but also avoid oral health problems (view on Amazon).

Today’s toothpastes have a lot of boxes to tick. Obviously, we expect them to clean our teeth and brighten our smile. But they also need to do this without damaging our teeth and, on top of that, work to protect and strengthen them.

As if that’s not enough, they have to taste good too, and prevent bad breath. Moreover, many studies reveal a close link between gum infection and cardiac and cardiovascular disease. So, toothpaste does matter.

But as a universal product, companies know there’s big money to be made from toothpaste. Because of this, there are literally hundreds of toothpastes available, and a minefield of competing claims for their effectiveness. So how do you know where to start?

This Uncle Harry’s toothpaste review will help provide general guidance and help you decide if it is right for you.

What makes a good toothpaste?

A good toothpaste must remove plaque and lift stains. Teeth naturally lose minerals each day and need to be able to absorb minerals (remineralize) from saliva and toothpaste products. This helps to protect them from decay.

To aid with these processes most toothpastes contain abrasives and mineral products. To disguise the taste of these ingredients and freshen breath, flavoring is added.

To achieve ADA accreditation, a good toothpaste should:

  • Contain at least 1000ppm fluoride
  • Not contain sugar – artificial sweeteners like saccharin should be used instead
  • Have a relative dentin abrasivity less than 250
  • Help you to maintain a great oral hygiene routine*”

*That is provide you with an enjoyable experience that you will want to take part in, not see as a chore. This could include elements such as taste, texture, design, etc.

Compared to ADA criteria, Uncle Harry’s may seem to fall short. However, it’s important to remember that this is a product that relies on long established natural ingredients to do its job, rather than modern chemicals.

If you are reading this article then presumably this matters to you, so read on to find out how Uncle Harry’s toothpaste could become an effective part of your daily oral health routine.

5 Things you need to know about Uncle Harry’s Toothpaste

1. Does it work?

Uncle Harry's Spearmint Remineralizing Toothpaste | Natural Whitening Toothpaste Freshens Breath &...

Uncle Harry’s is designed to target all your oral health needs, though it is not marketed as a whitening toothpaste (view details). Its principle ingredient is bentonite clay. The great thing about the clay is that it’s effective at lifting stains and cleaning teeth, but gentle enough not to damage the enamel.

In addition, bentonite clay rich in minerals which can easily be taken up by your teeth, partly because Uncle Harry’s does not contain glycerin – a common ingredient in modern toothpastes. Glycerin is thought to coat teeth and prevent them from absorbing the minerals naturally contained in saliva as well as toothpaste products. Teeth lose minerals every day so they need to be able to take up these minerals freely – Uncle Harry’s enables this.

Lastly, combined with other natural ingredients Uncle Harry’s helps to reduce the bacteria load in your mouth and neutralizes harmful bacterial acids, helping to fight plaque buildup and decay from acid attack.

2. Will Uncle Harry’s Toothpaste damage my teeth?

No. The clay in Uncle Harry’s which is the ingredient that lifts stains and cleans your teeth scores between 1 and 2 on the Mohs hardness scale which is very soft. It compares favorably with silica, a common abrasive used in conventional toothpastes, which scores 7 out of 10.

3. Does Uncle Harry’s Toothpaste protect your teeth?

Uncle Harry’s does not contain fluoride. This could be a bad thing or a good thing depending on your point of view. The ADA insist that a good toothpaste should contain fluoride and will not accredit toothpastes without it. On the other hand, there are some health concerns around the use of fluoride.

The clay in Uncle Harry’s is rich in the minerals that teeth need to replenish themselves, such as calcium, and the absence of glycerin means these minerals are easily taken up by your teeth.

The product itself helps to maintain a neutral ph value in your mouth, protecting your teeth from acid attack.

4. How does Uncle Harry’s taste?

Here is the potential fly in the ointment.

Flavors available are spearmint and anise, but the words ‘salty’ and ‘strong’ appear in many reviews regardless of flavor, though most users love it once they get used to it!

The most popular is size and flavor combination is the 3oz Spearmint flavor jar.

5. Is there something better?

This product is suitable for anyone who wants an environmentally friendly all natural product that is vegan and free from fluoride and gluten.

The taste is strong and although Uncle Harry’s provides a children’s version, it is still quite strong in flavor. In addition, bentonite does contain naturally occurring trace minerals and these can include lead.

4 thoughts on “Uncle Harry’s toothpaste review”

  1. I have been using Uncle Harry’s Peppermint toothpaste for about 10 years now. I tried the spearmint but think it is more a ‘ hot’ taste than the Peppermint. And also, you to not have to use very much to make it work. I have had no issues with cavities, and very little plaque buildup on my teeth. I have a mixture of crowns- porcelain and other- and natural teeth. I also use Tom’s Natural without fluoride toothpaste intermittently with the Uncle Harry’s in order to cut down on costs. With the Uncle Harry’s I really, really, feel like my teeth are clean after brushing instead of feeling a coating as with other toothpastes.

  2. Yes! I just started using Uncle Harry’s a couple weeks ago. I cannot believe how good my teeth feel. I have very sensitive teeth and used topical fluoride for years. I was concerned UH would bring back my sensitivity, but absolutely none. My teeth feel so great and really really clean! Worth every penny!
