Home » Does Purple Toothpaste Actually Work? Is This Safe For Your Teeth’s?

Purple toothpaste is a toothpaste that people talk about on social media, saying it makes smiles instantly brighter. But, even though many people are excited about it, the toothpaste doesn’t whiten teeth or remove stains. Instead, it only covers up the look of yellow teeth. Let’s find out how purple toothpaste works and what dentists think about this trend of trying to make teeth whiter.

What Is Purple Toothpaste?

Purple toothpaste is a special kind of toothpaste that is purple in color. It is not like regular whitening toothpaste because it does not usually have abrasives or bleaching agents. Instead, it contains pigments that counteract yellow tones on teeth. These pigments react with light, making your teeth look visually whiter. Some purple toothpaste also works as regular toothpaste, cleaning plaque and bacteria from your teeth. However, not all purple toothpaste has common toothpaste ingredients like fluoride. The idea behind purple toothpaste is similar to purple shampoo for hair. Just as purple shampoo combats brassy or yellow tones in blonde hair, purple toothpaste helps hide the yellow colors in teeth.

To make the toothpaste purple, companies use dental color correcting technology. This technology is based on the color wheel, where purple is opposite yellow. According to color theory, when complementary colors are mixed, they create either white or black. So, the purple color in this toothpaste neutralizes the yellow tones in teeth, making them look brighter and whiter.

Does Purple Toothpaste Work?

Purple toothpaste does not actually whiten teeth or reduce stains. It provides a quick fix for the appearance of white teeth in photos, but it is not a sustainable solution for whitening. The purple color in the toothpaste uses color theory to give the illusion of white teeth, but it does not deeply clean or bleach them. For effective teeth whitening, products need to remove both surface stains on the enamel (extrinsic) and bleach stains inside the tooth (intrinsic). Whitening agents like hydrogen peroxide or carbamide peroxide can penetrate deep into the teeth to brighten their appearance. Purple toothpaste lacks these ingredients, so it can’t bleach or whiten teeth in this way.

The purple color is a topical application that temporarily makes teeth look brighter, but the results only last for a few hours or up to a day. For a longer-lasting color change, other whitening products or natural methods may be more effective.

Is Purple Toothpaste Safe?

Purple toothpaste is generally considered safe for daily use, although the American Dental Association (ADA) has not officially approved any purple toothpaste for safety and effectiveness. Like some other whitening toothpaste, purple toothpaste may lead to side effects such as gum irritation or tooth sensitivity, particularly if overused or if there are pre-existing dental issues. The color in purple toothpaste comes from food dye, and temporary discoloration of the tongue or lips may occur. People with food dye allergies could experience rare allergic reactions, manifesting as symptoms like swelling, hives, or eczema flare-ups.

While purple toothpaste is generally safe, however, it is important to check for any known allergies to food coloring or dyes in the ingredients and follow the manufacturer’s instructions to minimize potential risks. Additionally, users should be cautious about potential staining on sinks, towels, or clothing and rinse the sink thoroughly after use. Despite its safety for daily use, most purple toothpaste brands do not include fluoride or other cavity-fighting ingredients. Therefore, it is recommended by the ADA to regularly use fluoride or hydroxyapatite toothpaste in conjunction with purple toothpaste for comprehensive dental care. To maintain optimal oral health, it is advisable to adhere to daily brushing, flossing, and regular dental visits, as some dentists express concerns that quick-fix products like purple toothpaste might compromise long-term dental health and appearance.

Side Effects of Using Purple Toothpaste?

Purple toothpaste might cause some problems. For example, it could turn your lips and mouth purple, but this is only temporary. If you are allergic to certain foods or dyes, using purple toothpaste could lead to a more serious reaction. Some people have noticed that their teeth look even darker after using purple toothpaste. Experts warn that the main problem with these trendy toothpaste products is that they might convince people to use them instead of dental products approved by the American Dental Association (ADA). Dentists are concerned that social media influences people to choose products based on looks rather than what’s good for long-term dental health.

According to Fryer, who is an expert, there is not enough information or research to support the use of these purple toothpaste products. The FDA only approves the synthetic colorants in these toothpaste, not the overall products. Additionally, the American Dental Association does not approve of these products. Instead, dentists recommend sticking to brushing twice daily, flossing daily, and talking to dental professionals about safe and effective whitening options.

Other Ways to Whiten Teeth

If you want your teeth to be whiter and stay that way, you can try different treatments. Here are some options you can find at the store or get from a dentist:

  • Whitening Toothpaste: This kind of toothpaste has stuff in it that helps get rid of stains on the surface of your teeth. Some may also have special ingredients that bleach your teeth to make them whiter.
  • Whitening Gel Pens: These pens have a gel with bleach in it. You put the gel on your teeth to make them whiter. You can use these pens when you need them or for about a week.
  • Whitening Gel Trays: These are trays you put on your teeth, and they have a gel with bleach. You keep them on your teeth for a while, usually up to 10 days.
  • Whitening Strips: These are like stickers with bleach on them. You put them on your teeth for about 30 minutes. They work well and are used every day for about two weeks.
  • At-Home Professional Whitening Trays: Dentists can give you custom trays with strong bleach gel. You wear them for a few hours each day for up to a month to make your teeth whiter.
  • In-Office Dentist Whitening: Dentists use strong bleach on your teeth, and sometimes they use a special light to make it work faster.
  • In-Office Enamel Microabrasion/Rubber-Cup Prophylaxis: For stains on the surface of your teeth, dentists may use a gel to remove a bit of the outer layer of your teeth. Rubber-cup prophylaxis is like a spinning brush that cleans your teeth.

When you pick a product at the store, look for the ADA Seal of Acceptance. It means the product is safe and works well according to the American Dental Association.


Even though some say purple toothpaste can whiten teeth or remove stains, it doesn’t really do that. Purple toothpaste uses a trick with colors to make yellow teeth look less yellow by putting purple dye on them. This makes it seem like your smile is whiter, but it’s only for a short time, and it won’t truly whiten your teeth in the long run. Also, many purple toothpaste products are not real toothpaste, so keep using regular toothpaste to prevent cavities.

For a brighter smile that lasts, consider using hydrogen peroxide methods like over-the-counter whiteners, professional bleaching at the dentist’s office, or at-home whitening trays.

Does purple toothpaste damage the teeth?

Purple toothpaste is a short-term solution to correct the color of teeth, and it does not make a permanent change. It is usually gentler than whitening products that contain charcoal, peroxide, or other strong chemicals to make teeth brighter. Instead of altering the teeth, purple toothpaste works by covering up temporary yellow colors on the teeth.

How long does purple toothpaste last?

The color correction that purple toothpaste provides is not permanent and lasts only for a few hours or up to a day. These temporary effects fade as you go about normal activities like eating and drinking. Because of this, people often use purple toothpaste before going out or for special events.

What whitens teeth?

Teeth can be whitened through professional dental treatments using strong bleaching agents or over-the-counter products like whitening toothpaste, strips, and gels. Other methods include activated charcoal and baking soda, but their effectiveness varies.

How long does it take to whiten teeth with purple toothpaste?

Even though your smile may appear noticeably whiter immediately after using purple toothpaste, this effect is short-lived—lasting only a few hours to a day. Consuming food or drinks may cause the whitening illusion to fade even sooner.
