About Twice Oral Wellness Products

1. Does Twice toothpaste whiten teeth?
Yes! Our chief formulator and oral health experts are the unofficial godfathers of teeth whitening, holding over 20 patents on teeth whitening technologies. Twice toothpaste utilizes two powerful methods of teeth whitening to naturally brighten your teeth over time as you brush: silicates and pentasodium triphosphate.

Silicates gently yet effectively buff and polish away plaque buildup, while our special ingredient, pentasodium triphosphate, safely uses chemicals to remove plaque. The result is a super-clean, glistening smile after every brush. Keep in mind that it can take 2 – 4 weeks to start seeing teeth whitening results.
2. Does Twice toothpaste help with sensitivity?
Absolutely! One active ingredient in Twice is Potassium Nitrate, commonly found in leading sensitivity protection toothpaste. Twice works hard to protect your teeth because we know there is nothing more painful than a bad reaction to hot/cold or sweet/sour foods. Twice’s ingredients work hard to build up protection for your teeth’s enamel over time - so that you can enjoy that cold drink pain-free!
3. Does Twice toothpaste have fluoride?
Yes, our award-winning 5-in-1 Oral Wellness Toothpaste with Fluoride is vitamin-enriched and naturally whitens teeth. For complete protection, it prevents cavities, reduces sensitivity, soothes gums, refreshes breath and improves the wellness of your mouth. Oh, and it also tastes delicious!
4. Does Twice make fluoride-free toothpaste?
Yes, for those who want an all-natural alternative to fluoride toothpaste, our Fluoride-Free Oral Wellness Toothpaste is formulated with activated charcoal and baking soda to naturally whiten teeth, hydroxyapatite to remineralize enamel and vitamins to improve the overall wellness of your mouth.
5. What ingredients are in Twice toothpaste?
Our products are formulated with high-performing, clean ingredients and backed by proven science to promote oral wellness and total mouth-body balance. Our vitamin-enriched award-winning 5-in-1 Oral Wellness Toothpaste includes vitamins A and E to promote healing and neutralize free radicals that can lead to gum damage, sodium fluoride to fight cavities and strengthen tooth enamel, potassium nitrate to prevent tooth sensitivity and aloe vera for its soothing anti-inflammatory properties. All of our products are free of SLS/SLES, parabens, gluten, BPA animal products and artificial dyes.
6. What do the vitamins in Twice toothpaste do?
The vitamins in Twice toothpaste (Vitamin A, Vitamin C and Vitamin E) balance bacteria, promote saliva production (and limit dry mouth), hydrate and strengthen your gums, fight free radicals and work to maintain optimal health in your mouth’s ecosystem to promote total mouth-body balance.
7. How is Twice toothpaste different from “regular” toothpaste?
While Twice may resemble familiar toothpastes, our formula stands in a league of its own. It begins with a simple belief — that a healthy mouth is a healthy body. Twice toothpaste isn’t just about teeth whitening and fresh breath. It’s an ultimate all-in-one solution, providing complete care for the teeth. Packed with special vitamins and antioxidants, it offers powerful benefits to your oral microbiome (your mouth) and your body to fortify oral health, reduce inflammation and ensure total oral health balance.
8. Is Twice toothpaste vegan?
Yes! Twice is perfect for anyone looking for vegan and cruelty-free products. Did you know some toothpaste contains ingredients derived from sources like animal fats? Our ingredients, like Glycerin, are derived from vegetables. We love our animals. The Twice HQ is packed with pets.
9. Can kids use Twice toothpaste?
Absolutely! We recommend our Fluoride-Free Oral Wellness Toothpaste as a great option for the whole family. It is powered by hydroxyapatite, a natural ingredient that safely yet effectively remineralizes enamel and fights against cavities to promote oral wellness without the use of fluoride. Kids love our flavors, and they remember to brush Twice!
10. What size is a tube of Twice toothpaste?
Twice toothpaste is 100 ml or 3.4 ounces. That means it should last about two months and is also travel-friendly! No need for additional mini tubes on your next trip.
11. Where can I purchase Twice products?
You can purchase Twice products on our site at www.smiletwice.com, at Walmart and at Target. Use our store locator to find the nearest place to buy our products or get them delivered to your door!
12. What toothbrush should I use with Twice toothpaste?
For the best results, opt for a soft-bristle toothbrush. This way, you’ll avoid irritating your gums and prevent enamel erosion.
13. Is Twice toothpaste non-GMO?
Yes, no GMOs here.
14. Is Twice toothpaste gluten-free?
Yes! Twice toothpaste is gluten-free. Interestingly, some toothpaste components can come from wheat, but that’s not the case with Twice. So, if you’re gluten-sensitive, no need to fret — it’s all good!
15. Is Twice toothpaste recyclable?
Yes! We are always looking for more ways to be eco-friendly. Our toothpaste tubes and caps are recyclable. Check out our Instagram account story highlights (@twice) to see how to do it!
16. How long does Twice toothpaste last?
Each tube of Twice toothpaste is 100 ml or 3.4 ounces and should last about two months per tube. You can also take our toothpaste anywhere with you, as 3.4 ounces is a TSA-approved carry-on size.
17. Will Twice toothpaste help with gum health?
Absolutely! The answer lies within our ingredients. Sodium fluoride helps coat your gums so that plaque can’t stick, and our vitamin and aloe vera blend combine to help heal, soothe and moisturize your gums.
18. Is Twice toothpaste ADA-approved?
Founded by a family of accomplished dentists and backed by dental experts, Twice uses ADA-approved suppliers to offer products designed to optimize your oral health for total mouth-body balance.

20. How does Twice Immunity Rinse compare to other mouthwashes?
Twice Immunity Rinse mouthwash lasts up to 5X longer than a standard 16-oz. mouthwash. Nano-emulsion technology delivers fast-acting and long-lasting freshness. The easy-to-use, travel-friendly bottle design has a dual-action formula with powerful ingredients to help safeguard against infection-causing bacteria, boost oral defenses and promote the healing of minor oral wounds.
21. Do Twice whitening strips work for sensitive teeth?
Yes! Twice whitening strips are the ultimate solution for teeth whitening without pain or sensitivity. The secret lies in dentist-recommended levels of hydrogen peroxide and soothing coconut oil, which help whiten and brighten teeth while reducing pain and gum sensitivity.

Twice vs. Competitors

1. How does Twice toothpaste compare to Crest?

Crest toothpaste includes fluoride, in combination with SLS and other abrasive foaming agents to remove plaque and surface stains to prevent and fight against tooth decay. In contrast, our award-winning, vitamin-enriched 5-in-1 Oral Wellness Toothpaste with Fluoride is powered by clean, vegan and high-performing ingredients formulated to elevate your overall oral health. 


Unlike Crest, our toothpaste is completely free of SLS/ SLES or any other potentially irritating abrasives. Not only does our toothpaste offer potent benefits to enhance oral wellness, but it also naturally whitens teeth, reduces sensitivity, soothes gums, refreshes breath and safeguards against cavities. Plus, as a testament to our commitment to quality, it is also free of parabens, gluten, BPA, animal-derived ingredients or artificial dyes.

2. How does Twice toothpaste compare to Sensodyne?
Sensodyne’s formula is more basic, focusing on potassium nitrate, fluorides, xanthan gum and hydrated silica to fight and prevent tooth decay, clean debris, and remove stains. Twice toothpaste, on the other hand, features a powerful plant-based and clean formula enriched with powerful vitamins to soothe inflammation and decrease free radicals to promote healthier gums.
3. How does Twice toothpaste compare to Hello toothpaste?
While Hello toothpaste excludes SLS, sulfates, BPA, gluten, dyes, and phthalates and is vegan, animal and cruelty-free, it misses out on the vital advantage of a vitamin-enriched formula that can truly elevate overall oral wellness. Twice toothpaste, on the other hand, is uniquely fortified with essential vitamins A and E, specifically chosen to foster healthier gums, reduce inflammation and neutralize free radicals that can contribute to gum disease. It also is powered by high-performing, vegan and clean ingredients formulated to improve oral health and promote total mouth-body balance.
4. How does Twice mouthwash compare to Listerine?

While LISTERINE® Antiseptic Mouthwash has a proven track record in promoting oral health, Twice Oral Wellness Immunity Rinse is designed not only to promote general oral health but also to enhance your mouth's natural defenses and support a balanced and healthy oral microbiome. See our article about LISTERINE® vs. Twice Oral Wellness Immunity Rinse for more information.

5. How does Twice mouthwash compare to Therabreath?

Like Therabreath, Twice Oral Wellness Immunity Rinse is alcohol free. Learn more in our comparison article of Therabreath vs. Twice mouthwash.

General Oral Health Questions

1. What are sulfates?

Not all foam is your friend. Do you remember the bubbles that fill your mouth when you brush your teeth? How could you forget, right!? Well, sulfates are the ingredients that cause that foam. Most sulfates, like Sodium Lauryl Sulfate, are known irritants that will dry the mouth, cause irritation and can lead to canker sores and even infection. An untreated infection can lead to life-threatening disease — there is nothing healthy about sulfates. The ingredients in Twice toothpaste that help create foam are derived from plants — we will never use sulfates.

2. What is hydroxyapatite?
Hydroxyapatite is a natural mineral that helps remineralize the teeth’s enamel, fight against plaque buildup and cavities, and enhance your overall oral health.
3. Will Twice help repair my enamel?
Yes, when used as recommended, Twice oral care products can help repair enamel in the early stages of tooth decay to remineralize and strengthen enamel by fighting against plaque buildup and cavities to prevent irreparable decay.
4. What ingredients should you avoid in toothpaste?

Your toothpaste should not include any known irritants and abrasive cleansers like sulfates, including sodium lauryl sulfate (SLS), that can dry out the mouth, cause irritation and lead to canker sores and infection. Learn more about toothpaste ingredients in our blog article.

5. How many times a day should you brush your teeth?
To keep your oral health in top shape, it is recommended by oral health professionals that you brush your teeth at least twice daily, being careful to reach every corner for a minimum of two minutes each time. Thoroughly cleaning your teeth is essential to remove plaque buildup that can cling to the enamel and eventually lead to tooth decay.
6. How often should you floss your teeth?
Make flossing a daily habit to avoid plaque buildup, preventing tooth decay and gum disease. Especially after sugary or starchy meals, a quick brush and flossing session can swiftly remove any lingering plaque and help maintain strong, healthy enamel.
7. I have a toothpaste allergy. Can Twice help?
Yes! If you happen to have a toothpaste allergy, fret not. Twice oral care is packed with vegan, clean and gentle ingredients designed to enhance your oral health with both safety and efficacy in mind. What’s more, Twice spares you from many known irritants — no sulfates or SLS here. Additionally, Twice is gluten-free, paraben-free, BPA-free and as free of any artificial dyes.
8. What oral health issues can Twice help resolve or prevent?
Enriched with vitamins and aloe vera, our formulas offer soothing and healing benefits to protect the health of your gums. Dentist-level recommended hydrogen peroxide and coconut oil tackle teeth whitening without sensitivity woes, while sodium fluoride and hydroxyapatite banish plaque buildup to prevent tooth decay and champion overall oral wellness.
