If you want science-level oral hygiene, you’ve come to the right article. Toothbrush commercials and ads can take a break as we go over the oral hygiene products that have a Canadian Dental Association (CDA) seal of approval.

That seal is what you’re looking for when you’re doing your oral hygiene shopping. When you see that seal you know that the claims made by the manufacturer are validated by the CDA. You can even put a name to that validation, Dr. Aaron Burry, the CDA’s deputy CEO, professional affairs, confirms that all products below do what they say they will do.

Before we dive mouth-first into toothbrushes, let’s discuss which one is better; manual or electric. Dr. Burry says that “both types can be equally effective at removing plaque that causes tooth decay and gum disease.” adding, “People, who for different reasons may lack the dexterity required to use a manual brush, may benefit from the use of an electric toothbrush.”

Also, toothbrushing technique is the most important factor. Dr. Burry says that we should be using soft toothbrushes and ensure to brush gently.

The iO Series 8 has a linear magnetic drive system that directs cleaning energy to each bristle. The toothbrush uses a light system to monitor pressure; green means good pressure and red means too hard.

The toothbrush will greet you when it turns on and it comes with a magnetic charger. It comes with seven cleaning modes: daily clean, sensitive, super sensitive, intense, whiten, gum care and tongue clean (which is unique to this model). The Series 9 is the only model that comes with a charging travel case.

Oral-B iO Series 8

The Series 8 has the same core details as the Series 9, it just comes with six cleaning settings (same as above but without the tongue clean setting). It’s also the more affordable option between the two, and is more budget-friendly if you don’t want to splurge on the latest and greatest device.
