This $140 AquaSonic electric toothbrush kit is only $40 today

Maintaining proper dental hygiene can seem like a chore, especially when you're using less than stellar equipment. Electric toothbrushes are drastically more effective than your run-of-the-mill manual toothbrush, but they tend to cost significantly more. The AquaSonic Black Series toothbrush, however, packs all the power you've come to expect from an electric toothbrush but at a price that's much more affordable—just $40 today.

Thanks to a powerful motor, the AquaSonic vibrates much faster than many other brushes from top brands. This helps to dissolve stains and whiten your teeth, without the need to apply pressure.

The brush has four cleaning modes: soft, whiten, massage, and cleaning. Soft mode is perfect for sensitive teeth, while massage mode makes the brush pulse to stimulate your gums. In turn, this can improve your gum health — some users see an improvement within one week.

With this offer, the Black Series brush comes with a sleek travel case and eight extra Dupont brush heads.

It’s normally priced at $139.99, but you can pick up the AquaSonic Black Series for $39.99 with this deal.
