1. Cocofloss ($9)

Created by sisters who wanted a better floss, Cocofloss has quickly become a dentist (and celebrity) favorite. The textured but easy-­gliding polyester thread is coated with coconut oil, which has anti-microbial properties and is naturally soothing to gum tissue. Buy it at Cocofloss.

2. By Humankind Mouthwash ($10)

A mouthwash that comes in tablet form offers obvious advantages. To reduce plastic waste, the manufacturer sells refills for its handsome reusable jar. Just drop the tablet in water to create a swig of ­alcohol-free mouthwash in any of five flavors. Buy it at By Humankind.

3. Marvis Toothpaste ($11)

Tired of the look and taste of Crest? Marvis, an Italian company founded in 1958, offers "­apothecary-chic packaging," and its fluoride toothpastes come in flavors such as ginger, licorice, cinnamon, and jasmine mint. Buy it at Amazon.

4. Radius Source ($10)

The large brush head and "easy-to-grip" handle make the Radius the perfect manual toothbrush. It's the sustainable choice, too. Its plastics are plant-based, and you can replace the head but re-use the wooden handle. Buy it at Radius.

5. Waterpik Aquarius ($85)

An option for anyone who hates flossing, this sturdy, effective machine "comes as close as any water flosser to delivering that 'just left the dentist' feeling," writes Shannon Palus at The Wirecutter. It contributes to tooth and gum health, and its pressurized water stream is highly customizable. Buy it at Bed Bath and Beyond.
