![]() Not only was this rather disturbing (and gross), but I'm sure that over time this would absolutely become harmful to my teeth or gums. When gently picking underneath my gums with a toothpick, I found SEVERAL of these little blue crystals lodged far up into my gums. After my husband pointed it out to me a few days later I decided to inspect further. This was fairly sudden, and it was noticeable. One day I noticed a strange dark spot on my gums above both of my two front teeth. Product supposedly contains blue plastic capsules that "dentists are finding stuck in patience gums." This warning could reference any one of a number ofĮntries in the line of Crest products aside from Crest 3D White "Arctic Fresh" toothpaste, such as Crest 3D White "Vivid" toothpaste or Crest Complete Extreme Herbal Mint toothpaste, which contain hydrated silica, a sand-like substance that serves as an abrasive to exfoliate the teeth of food and other particles, and/or polyethylene (known as microbeads), which according to Crest is "a safe, inactive ingredient used to provide color" that gives a product the appearance of containing small beads or flecks:Īs the Los Angeles Times observed in a 2011 survey of whitening toothpastes, Crest 3D White Vivid ranked as one of the most abrasive such toothpastes on the market: In March 2014, Facebook posts began appearing warning consumers away from Crest 3D White brands of toothpaste, accompanied by a picture of the "Arctic Fresh" variety, because the Heads will turn, and youÃ?Â?Ã?¢Ã?Â?Ã?Â?Ã?Â?Ã?Â?ll leave an unforgettable impression.Ĭrest and Oral-B offer the transformative power of a 3D White smile to people everywhere, without the confusion or trade-offs of other whitening products available today, and with the health benefits you expect from Crest and Oral-B. Every time you flash your brilliant 3D White smile, you'll stand out. Incorporate the entire 3D White collection into your daily routine for a standout smile all year long. Each product in the 3D White collection works uniquely to give you a stand out smile. Anything higher than that may be harmful, but the maximum amount approved by the FDA is 200, Khan says.New Crest 3D White is a collection of products that work together to give you a brighter smile - plus the health benefits you expect from Crest and Oral-B. An RDA value of 0-70 means low abrasion, 71-100 is medium abrasive, and 101-150 is highly abrasive. To determine a toothpaste's abrasion, you should check its RDA value, Khan says. Higher abrasion can mean more irritation for those with sensitive gums or teeth. Lastly, some whitening toothpastes are more abrasive than others. You should also be cautious of using multiple whitening products at once, since this can disrupt the enamel and cause more sensitivity. If you do start to notice any sensitivity, she recommends then switching to a desensitizing toothpaste with one of these active ingredients-potassium nitrate, stannous fluoride, or strontium chloride to help with the sensitivity. "The majority of whitening toothpastes state they have been tested and are safe to use twice a day for two minutes," says. When using a whitening toothpaste, you pretty much use it like you would any other paste. To combat this, opt for toothpastes with a low abrasion level or with lower concentrations of ingredients, like peroxide. If you lose enamel, your teeth in turn will appear more yellow. "These ingredients can lead to enamel-wear, which can cause sensitivity and affect overall aesthetics due to their abrasive nature," Khan says. There is a downside to these ingredients, though, Khan says. "It restores mineral density and therefore makes teeth appear whiter and less translucent." Fluoride can help control cavities and strengthen your tooth enamel. "Hydroxyapatite is another ingredient that helps remineralize your teeth and remove extrinsic staining," says Khan. Next, you should look for ingredients, like fluoride and hydroxyapatite. You can also ask your dentist what they carry at their office if you're looking for suggestions, says Tabaraie. "When choosing whitening toothpaste go with one with the ADA seal because it has been tested for safety and efficacy," says Khan. First things first, check for an American Dental Association seal (ADA).
