All the best Amazon Prime Day electric toothbrush deals have landed, with huge savings on top brands like Oral-B, Philips, Colgate, AquaSonic, and more. 

Everyone knows that a good electric toothbrush is essential for maintaining a good oral hygiene routine. Not only are they better for stain removal, but they're also clinically proven to remove more plaque than a manual brush, so investing in a good one will have a long-term payoff. As Amazon Prime Day draws to a close, prices have been slashed further, with some brands offering up to a huge 75% off products.

That doesn't mean you have to spend major money on one though, as many of the best electric toothbrushes are on sale with up to $100 off - including the latest Oral-B iO9 (opens in new tab). If you're in the UK, you can save a huge £127 on the Oral-B Smart 6 electric toothbrush (opens in new tab) and $250 if you're based in the US. Our favorite of the electric toothbrush deals has to be the Oral-B iO9 (opens in new tab), which is down to $227.96 with a saving of $71.98. This brush has clever technology featuring a range of modes and an interactive interface for the smartest clean we’ve seen.
