The Oral-B Pro-Health Clinical Battery Power Electric Toothbrush is a battery-powered toothbrush that comes with replaceable brush heads. It is compatible with Oral-B Replacement Brush Heads such as CrossAction, Sensitive Gum Care, FlossAction, and 3D. The toothbrush is powered by two AA batteries, which are included in the pack. The brush head is designed to reach deep between teeth to remove plaque, and it has a precision clean brush head that delivers a dentist-inspired tooth-by-tooth cleaning. The toothbrush also has a brushing timer feature to help users brush for the recommended two minutes. The toothbrush is hard-firmness, and the pack of one includes everything needed, making it an economical and efficient choice.

The Oral-B Pulsar Whitening Battery Toothbrush is another battery-powered toothbrush that gently vibrates and polishes away stains for a whiter, cleaner smile. It uses the same technique to brush as a manual toothbrush, but with the added benefit of gentle vibrations.

The materials used in the toothbrushes are not explicitly mentioned in the search results. However, a review article on powered toothbrushes mentions that toothbrushes include both manual and powered ones, and polyethylene (PE) is a long polymer chain synthesized from ethylene monomers.

In terms of positive aspects, powered toothbrushes have been found to have a slight edge over manual ones when it comes to plaque removal. A 2021 meta-analysis of 28 studies provided further evidence that powered toothbrushes seem to have a slight edge over manual ones when it comes to plaque removal. The oscillating powered toothbrushes were slightly better at reducing plaque than sonic electric toothbrushes.

On the negative side, a 2017 study published in the journal PLOS One found that electric toothbrushes were more likely than manual to abrade dentin, which can increase tooth sensitivity and hike cavity risks.

Regarding eco-friendly toothbrushes, the Hello Products Bamboo Charcoal Toothbrush is made with activated charcoal derived from sustainable bamboo and has an ergonomic handle made with plant-based materials. The soft bristles are made to clean between tight spots with ease.
