Activated charcoal is the craze in the beauty industry to help get those pearly whites, but at what cost is it taking on oral health?What is activated charcoal?It's not the charcoal used in your backyard barbeque. According to Dr. Todd Shatkin of Aesthetic Associates Centre in Amherst, New York, it's a slightly abrasive powder usually formed by coconut and is used in many different aspects of the health industry. Activated charcoal is an absorptive property, and it's designed to absorb and lift blemishes from teeth.It's used for cleansing, weight loss treatments, and skin care products. Now it's being used for teeth whitening to remove stains. How does it work?A toothbrush is dipped into the powder and is brushed directly onto teeth. The activated charcoal powder removes the extrinsic stains; stains that are caused by wine, coffee and other foods and drink. "Charcoal-based products would be good to remove the surface stain, but it won't internally bleach or whiten the teeth from within," Shatkin said. Is activated charcoal safe to use?Shatkin says yes.He says, to first make sure the product is FDA approved, and check the abrasiveness level. "The enamel is really pretty strong," he said. "If you're in the enamel your probably not going to do any harm to your teeth. But if the patient has worn through the enamel into the dentin, it causes sensitivity and causes discomfort. If you use abrasive materials on the dentin, it will just make things worse."He says, in the end, it all comes down to good oral hygiene and visiting your dentist every three to six months. 1716

Airbnb announced new rules for New Year's Eve to prevent parties and large gatherings at its properties amid a surge in coronavirus cases.The vacation rental company released its plan on Thursday to limit rentals in the United States, the United Kingdom, Canada, Mexico, Australia, France, and Spain.The new measures state that Airbnb would require guests who don't have a positive review history to book a minimum of two nights for any stay, including Dec. 31. Any guests with reservations on Dec. 31 must swear that they will not throw a party under threat of legal charges.The company said that guests who have a history of positive reviews on Airbnb would not be subject to this restriction.The company said it would allow already-booked one-night reservations to continue as planned since their "data has historically shown that one-night New Year’s Eve bookings made prior to now very rarely lead to unauthorized parties." 936
