It’s easy to get lost in the flashy discounts for all kinds of electronic devices in Amazon’s Prime Big Deal Days 2025, but you shouldn’t forget to spend on your wellbeing and hygiene. Here’s an early offer from the upcoming shopping event that we recommend — the Oral-B iO Series 3 electric toothbrush at 40% off, slashing its price from $100 to only $60. The savings of $40 are only available to Amazon Prime subscribers though, which gives you another reason to either sign up or access the Amazon Prime free trial.
Why you should buy the Oral-B iO Series 3 electric toothbrush
If you need a new electric toothbrush, you can’t go wrong with Oral-B as it’s among the most trusted names in the industry. The Oral-B iOS Series 3 is one of its more affordable models, but it will make sure you’ll able to better clean your teeth. It’s equipped with a sensor that can detect if you’re applying just the right amount of pressure, as well as a built-in timer that lets you know if you’ve reached the brushing time of 2 minutes that’s recommended by dentists. You also have three cleaning modes to choose from — Daily Clean, Sensitive, and Whitening.
The Oral-B iO Series 3 electric toothbrush comes with two rounded brush heads — which can reach areas that rectangular brush heads can’t — and it has an indicator light to tell you if the brush head needs replacing. With micro-vibrations and oscillating action, the brush heads work with the electric toothbrush to ensure a complete clean every time. It also comes with a charging station so that the Oral-B iO Series 3 is always ready.
Prime Big Deal Days isn’t until next week, but we’re already starting to see offers such as this 40% discount on the Oral-B iO Series 3. In one of the most interesting electric toothbrush deals today, you’ll only have to pay $60 instead of $100, for savings of $40. You shouldn’t wait until the final minutes of the shopping event before you make the purchase though — if you can, add the Oral-B iO Series 3 electric toothbrush to your cart and complete the checkout process right now.
