Purple Toothpaste: Does It Work and What To Expect?

If you have ever struggled with teeth that are not quite bright enough, you might have attempted whitening techniques. Brightening teeth is not new method. But purple toothpaste is. Yes, you read that right. Purple toothpaste. It may be the newest craze in teeth whitening products to hit the market.

So, let’s see what makes purple toothpaste unique, the science behind it, and whether you should try it.

Purple toothpaste: What is it?

Purple toothpaste contains color-correcting pigments, to potentially counteract the yellow shade. It was developed from a similar theory to purple shampoo. The shampoo uses purple colors to combat yellow tones in blonde hair. The same concept was applied to develop purple toothpaste, with aim to mask the yellow undertone in teeth.

Purple toothpaste utilizes what brands call dental color correcting technology to potentially make teeth appear brighter. Toothpaste companies use FDA-approved synthetic colorants to give the toothpaste its bluish-purple hue.  

Color correcting technology starts with a simple, scientific tool — the color wheel. Purple is directly opposite yellow on the color wheel, making them complementary colors. According to the color theory, when complementary colors are mixed, they create either white or black. Alas, the purple color in this toothpaste neutralizes the tooth’s yellow tones, making teeth appear brighter and whiter.

Does purple toothpaste really work?

As with any product, you want to know if it works before taking the plunge. Purple toothpaste is not a typical whitening product. So, how does it work? As mentioned before, purple toothpaste uses color-correcting technology to alter the appearance of stains on your teeth. Therefore, it does not actually remove the stains or change your teeth in any way.

Most whitening toothpastes uses a combination of peroxides and abrasives to remove stains from teeth. The active ingredients reach the stains on the teeth and masks the yellow dental color. Although occasional whitening is relatively safe for teeth, some products can increase the risks of:

  • Roughening tooth surfaces
  • Weakening the enamel
  • Breaking down restorations
  • Staining on and around restorations
  • Increasing sensitivity

Using a purple whitening toothpaste can make teeth appear brighter. However, the color is simply a topical application that temporarily makes teeth appear whiter. You can expect results to last from a few hours or up to a day. If you are looking for a longer-lasting color change, you may want to try natural teeth whitening techniques or other whitening products.

Is purple toothpaste safe?

Purple toothpaste is generally safe for daily use. Most purple toothpaste products use dental color correcting technology without harsh chemicals and abrasives. However, important to note, there are few risks for adverse reactions. If you have a known allergy to food coloring or dyes, be sure to check the ingredients before using. Also, carefully read and follow the instructions provided by the manufacturer to minimize any potential risks.

Although purple toothpaste does not stain teeth purple, it can stain your sink, towels, or clothes. So, use caution when brushing with purple toothpaste for whitening. Be sure to rinse your sink thoroughly after using. If staining does occur on your sink or clothing, a thorough scrubbing should lighten the stains.

Using purple toothpaste is fine for temporary whitening, but most people still need the cavity protection of fluoride. What good is having white teeth with cavities?

Purple toothpaste is safe enough to replace your regular toothpaste. However, most brands do not include fluoride or other cavity-fighting ingredients.

The American Dental Association recommends using toothpaste with fluoride to reduce the risk of cavities, strengthen and protect your teeth.

Purple toothpaste reviews: Different brands

There are a lot of purple toothpaste brands hitting the market. Most of them use similar dental color-correcting technology to brighten your smile. Let's compare three of the top-selling purple toothpaste for teeth whitening.

Hismile V34 Colour Correcting Serum

Technically, Hismile is not a toothpaste but rather a purple serum. You apply it to your toothbrush just like you would toothpaste and brush normally. The serum is not meant to replace your normal toothpaste. Hismile serum is designed to work best with their whitening treatments.

Hismile purple toothpaste uses two water-soluble dyes that aim to correct yellow tones. Hismile serum is also peroxide-free, which makes it a safer option than whitening products using harsh chemicals to whiten teeth. Many claim this serum is excellent for a night out or a special event when you need that white smile fast.

POPWHITE Natural Teeth Whitening Primer Toothpaste

This toothpaste is designed to replace your regular toothpaste. Other Popwhite products are available to use with the primer toothpaste to support the whitening effect. Each product uses the same color technology.

Popwhite whitening purple toothpaste does not contain fluoride, sulfates, or harsh chemicals. It is infused with coconut and peppermint oils for a fresh taste. The effects are temporary and fade throughout the day. However, users love how gentle it feels compared to other whitening products.

Crest 3D White Brilliance Luminous Purple Toothpaste

Crest is one of the first big toothpaste brands to join the whitening purple toothpaste game. Crest purple toothpaste claims to mask more surface stains in three days than regular toothpaste. And when used twice a day, it may provide 24-hour stain protection from new stains forming.

Crest is one of the few purple toothpastes that provides cavity protection using fluoride. Reviewers rave over the refreshing, minty taste and how clean their teeth feel after brushing.

Purple whitening toothpaste pros and cons

Although purple toothpaste is considered a whitening agent, several significant differences exist. Purple toothpaste uses dental color-correcting technology to make teeth appear whiter. The results are temporary and last between a few hours or up to a day.

Dental color correction does not alter the tooth color itself. Instead, the tiny color particles in the toothpaste temporarily mask the yellow hues in enamel, making teeth appear whiter.

As normal activities like eating and drinking continue, the color change will fade. Therefore, most purple toothpaste brands recommend using the toothpaste 1–2 times daily. This helps to prolong the dental color-correcting effect.

Purple toothpaste may be the next whitening fad, but if you are looking for a quick and simple fix, you should try it. The advantages outweigh the disadvantages, and with a minor risk of side effects, why not give it a chance? Purple toothpaste may be the fastest way to whiter teeth you have ever tried.
