Amazon Prime Day electric toothbrush deals: FAQs

Do I need to get Amazon Prime to get the best electric toothbrush deals?

Yes, to put it bluntly. Amazon loves to run sales events exclusive to Prime members in order to entice people to sign up to its premium service, so some discounts will be hidden from, or inaccessible to, non-Prime members.

Fortunately, it's great value if you're a regular Amazon user, but you can cancel after the event is over if you don't want to pay that $14.99 / £8.99 / AU$9.99 subscription service price. More on that in a minute.

Which electric toothbrush should I buy on Amazon Prime Day?

That's a tough one, and it will all depend on your budget and needs. If you're prepared to spend hundreds of pounds or dollars, you're likely to get a much bigger discount (for example, in the US, you might get a $400 toothbrush marked down to $250) than you would on a cheaper toothbrush, so the more you spend, the more you'll save. An Oral-B iO Series brush, is probably your best best.

However, when it comes to cheaper toothbrushes, you might be able to get brushes like the Colgate Hum or Ordo Sonic+ for half price or more. Don't forget about replacement heads either, as bundle deals will crop up: shop right, and you could get a year's worth of brushing on the cheap. 

How to get access to the Amazon Prime Day electric toothbrush deals for free

When you sign up to Amazon Prime, you get your first 30 days with the service free. When you're finished shopping the deals, you can simply cancel your Prime subscription before the 30-day mark and you'll never have to pay a thing for the service. 

However, it is a good opportunity to see what you get with Amazon Prime, including Prime Video (one of our best streaming services), Priem Music, Gaming and of course free delivery from Amazon itself. More about this below:
