Amazon Prime Day: Top Electric Toothbrush Deals for 2025
Amazon Prime Day is in full swing, and there are some impressive discounts on some of the best electric toothbrushes from leading brands like Oral-B, Philips, Suri, and more. As someone who has spent years researching and testing electric toothbrushes, I know how to spot a genuine discount from a misleading offer. Throughout the sale, I will be tracking Prime Day deals in real-time to bring you only the most valuable bargains.
One of the key pieces of advice I have for shoppers looking for electric toothbrush discounts is to be cautious of misleading offers. You often see deep discounts of 50 per cent or more on popular models, but these savings tend to repeat throughout the year. To help you avoid falling for fake bargains, I track the prices of electric toothbrushes all year round, allowing me to filter out the fakes and focus on the real deals.
Whether you’re looking for a high-tech model with AI coaching and pressure sensors or a reliable brush that gives you a dentist-fresh feeling, I will keep updating this page with new offers as they become available.

What is Amazon Prime Day?
Prime Day is Amazon’s exclusive mega sale for its Prime members. It typically runs for 48 hours, but this year you’ll have four days to shop the sale. It usually happens twice a year – once in the summer and again in the autumn. During the event, shoppers can find huge discounts on major brands, including top-rated, tried and tested electric toothbrushes.
Do You Need to Be a Prime Member to Shop for Electric Toothbrush Deals?
Yes – access to Prime Day discounts is limited to Amazon Prime members. A membership costs £8.99 per month or £95 annually, though students and young adults (ages 18–22) can claim a 50 per cent discount and a six-month free trial. Perks go beyond the sale and include speedy delivery, Prime Video, and access to exclusive deals.
If you’re not already a member, you can still take part by signing up for a 30-day free trial. This gives you full access to Prime Day offers – including any price drops on premium toothbrushes – with the option to cancel before being charged. Just note: the free trial only works if you haven’t used it before.
