NEW LONDON, Conn. — Sheffield Pharmaceuticals has expanded its Dr. Sheffield’s Certified Natural Toothpaste line with an activated charcoal toothpaste.

Dr. Sheffield’s Certified Natural Activated Charcoal Toothpaste has been shown to safely and effectively whiten teeth, remove stains, reduce plaque and freshen breath, providing an alternative solution for teeth whitening, the company said.

The new product joins extra whitening, natural wintergreen, natural peppermint and sensitive care varieties in the brand’s fluoride-free toothpaste lineup.

Charcoal is a key ingredient for oral care because, once activated and added to toothpaste, it can absorb impurities and remove stains when brushing, Sheffield noted. The brand’s charcoal toothpaste removes plaque, food particles and stains from coffee, tea and wine.

Activated charcoal is tasteless, odorless and balances pH levels to help eliminate the bacteria that causes bad breath. Dr. Sheffield’s variety is creamy, black and formulated with activated charcoal made from eco-friendly coconut husks. It contains real peppermint flavor and coconut oil for a fresh, natural taste. It’s also made with natural pectin from orange peels and aloe vera, which the company said provide moisture to soothe the mouth.

The toothpaste gently polishes teeth and does not contain any harsh, synthetic bleaching agents that can cause tooth sensitivity, Sheffield added.

“Dr. Sheffield would never have envisioned a future where toothpaste would be filled with synthetic substances. We’re on a mission to clean up toothpaste and bring our effective natural formulas to families across the country,” statedd Jeffrey Davis, president chief executive officer of Sheffield Pharmaceuticals.

Dr. Sheffield’s Certified Natural Toothpastes are sold at CVS Pharmacy, CVS.com, Bed Bath & Beyond, BedBathandBeyond.com and HarmonDiscount.com. All varieties contain no fluoride; GMOs; synthetic detergents or foaming agents; or artificial colors, flavors or sweeteners.
