Everything You Need to Know About Tooth Powder

What is Tooth Powder?

In the 1800s, it was common for people to use tooth powders containing baking soda, chalk, or salt to remove mouth odor and polish teeth. Today, it's gaining popularity again.

Tooth powder's appeal includes:

• Fewer and more natural ingredients
• Able to eliminate toxins
• Believed to be able to cure tooth decay (this has not been scientifically proven)

Tooth powders can be purchased from manufacturers or made at home. Common ingredients include:

• Baking soda
• Activated charcoal
• Bentonite clay
• Coarse sea salt
• Essential oils
• Flavorings

Tooth Powder vs. Toothpaste

There is limited research that has compared toothpaste to powder. However, those published show mixed results on tooth powder's overall effects on oral health.^1,2,3,4,5,6

The main concerns regarding tooth powder are its abrasiveness and effectiveness at removing dental plaque. A buildup of plaque can lead to cavities and tooth decay.

A few studies showed that tooth powder might be too abrasive compared to toothpaste. This can result in dental erosion. However, its abrasiveness can effectively polish stains off the surfaces of teeth.^4,5

The findings are mixed regarding tooth powder's effectiveness at removing plaque. Some studies say toothpaste remains more effective, while others say tooth powder results are comparable to toothbrush and paste.^1,2,3,6

Is Toothpaste Better than Tooth Powder?

Regarding the research that backs its effectiveness, there are more studies covering the effects of toothpaste. It has continuously been proven effective at protecting against oral issues, which include:^7,8,9,10

• Cavities
• Lessening tooth sensitivity
• Whitening teeth
• Reducing plaque and tartar buildup
• Preventing gingivitis
• Preventing enamel erosion
• Reducing bad breath

NewMouth recommends using toothpaste with the ADA Seal of Acceptance to brush your teeth. All toothpaste with the ADA Seal of Acceptance has provided scientific evidence proving the safety and efficacy of the paste.

The ADA Council on Scientific Affairs reviews all applications and determines acceptable products. Any toothpaste that contains flavoring agents that cause tooth decay is rejected.

Toothpaste can expire, so be sure to check the expiration date.

How to Use Tooth Powder

Tooth powder should be used the same as toothpaste. The only difference is that it needs moisture to spread over the surfaces of your teeth. 

Simply wet your toothbrush, then dip the bristles in your tooth powder. Brush for two minutes and spit the tooth powder into your sink. Rinse as you normally would.

Does Tooth Powder Have any Benefits?

Toothpowder has not been studied as extensively as toothpaste. However, there have been a few studies that have examined the effectiveness of toothpowder.

Here’s what the science says:

Reducing Plaque

Plaque is a sticky film made from bacteria that forms on your teeth daily. When it builds up, it turns into tartar.

Three scientific studies have shown that tooth powder is equally or more effective at reducing plaque than toothpaste.^1,2,3 This is likely due to the abrasive nature of tooth powders.

However, another study from 2018 compared traditional oral hygiene methods to toothpaste users. This study showed contrasting evidence to the other studies. It found that traditional methods, including tooth powder, were inferior in plaque control compared to toothpaste.⁵

These mixed results show that more evidence is needed to prove whether tooth powder is as effective as toothpaste at reducing plaque.

Controlling Gingivitis

When plaque builds up on teeth, it can cause inflammation, pain, and infection in your gums. This can lead to gingivitis (early gum disease). If gingivitis goes untreated, it can turn into periodontitis (advanced gum disease).

Current scientific evidence shows that tooth powders may be effective at reducing plaque and, therefore, gum disease.1, 2, 3 However, more evidence is needed to determine whether tooth powder effectively controls gingivitis.

Whitening Effects

One study has shown that tooth powder efficiently removes extrinsic (surface) stains from your teeth.⁵ This study noted that the whitening effects of the tooth powder were greater than that of the toothpaste. However, the toothpaste was just a general toothpaste, not a whitening toothpaste. 

Tooth powder is likely an effective whitening agent due to its abrasive properties. But again, more research is needed to determine the effectiveness of tooth powder in removing stains from your teeth.

Are There any Negative Effects of Tooth Powder?

The abrasiveness of tooth powder may help remove surface stains. However, it can also have negative effects on your teeth.

One study found that tooth powder can cause bleeding, gum loss, and damage to your enamel (tooth surface).⁴ Another study showed that tooth loss was higher in people who brushed with red tooth powder due to its high abrasiveness and chemical composition.⁵

Pros and Cons of Toothpowder

There are both pros and cons of toothpowder:

Pros

• Tooth powder is likely an effective way of controlling plaque build-up
• Less plaque build-up helps reduce gum disease (gingivitis and periodontitis)
• The abrasiveness may help left surface stain and improve the white color of your teeth
• Can be made at home, so you have more control over the ingredients
• Can be made customizable depending on oral health needs and allergies

Cons

• There is very little scientific evidence to prove the effectiveness of toothpowder
• No tooth powder has received the ADA Seal of Acceptance
• Too much abrasiveness can have harmful effects on your mouth
• May cause negative effects, including bleeding, gum loss, enamel damage, and tooth loss
• Many tooth powders do not contain fluoride

Summary

Tooth powder has been used as an oral healthcare product for centuries. It's an effective way to reduce plaque, control gum disease, and whiten teeth.

However, studies are concerned about its ability to cause gum bleeding, gum recession, enamel damage, and tooth loss. More studies are needed to prove claims for or against tooth powder.

In comparison, toothpaste is proven to protect against cavities, lessen tooth sensitivity, whiten teeth, reduce plaque, prevent gum disease and enamel erosion, and reduce bad breath.

NewMouth recommends using toothpaste with the ADA Seal of Acceptance to brush your teeth twice daily. You should also floss once daily and rinse your mouth with mouthwash to maintain a proper oral health care routine.
