Electric toothbrushes are overpriced, but these Prime Day deals are worth smiling about

Electric toothbrushes vary enormously in style and price, from highly advanced AI-driven monstrosities to simple battery-powered sonic devices. Prices can run into the hundreds of pounds, which sounds wild for something you clean your teeth with, but fortunately you can pick up a perfectly good toothbrush for a lot less. 

I'm convinced the toothbrush companies are aware of the massive markup, too. Enter the October Amazon Prime Day deals, or the Big Deal Days event as Amazon is calling its latest sales.

Best Amazon Prime Day water flosser deals

Water flossers are a relatively new product, but they're proving increasingly popular, as they eliminate household waste caused by disposable reels of dental floss. 

They pump water from a small personal reservoir and spray concentrated jets of water into your mouth, dislodging chunks of food just like flossing. They're rechargeable and obviously refillable, so you end up saving money long-term and reducing plastic usage.

Below are the two Prime Day deals I'd pick, based on what I've seen so far:

Waterpik Nano Plus water flosser: was £74.99£49.99 at Amazon

Waterpik Nano Plus water flosser: was £74.99 now £49.99 at Amazon
Water flossers are devices that dislodge the gunk between your teeth with concentrated jets of water. They're much more sustainable than disposable floss, and cheaper in the long run – and right now you can save £25 on one of the best-known of the bunch, the Waterpik Nano.

Panasonic EW-DJ11 Compact & Portable Water Flosser:was £59.99£31.99 at Amazon

Panasonic EW-DJ11 Compact & Portable Water Flosser: was £59.99 now £31.99 at Amazon
Panasonic's EW-DJ11 water flosser is a travel version with a built-in reservoir. It collapses down like a toy lightsaber for easy storage, has two pressure settings, and is powered by AA batteries.
