With three replacement brush heads, a powerful charging travel case, and an AI-powered app, there's loads to love about this high end electric toothbrush. Save $90 this Prime Day.

There's no doubt that the Oral B iO Series 9 is a premium gadget, with no less than seven brushing modes. This includes sensitive and super sensitive modes for those with more sensitive gums. There's even a tongue brushing mode, which isn't something we've seen on other electric toothbrushes.

But the real 'wow factor' of this toothbrush is the AI-powered app. Once you're connected, you can track your session. The app will show you the zones of your mouth you've been brushing, and will assign you a score to help you improve brushing next time. The battery life is also great – we went through 15 days of regular brushing without needing to recharge it. 

If you're looking to seriously invest in your oral health, don't miss out on a huge $90 saving right now with Amazon Prime Day.
