Why Crescent Nest Tops the List

 

Sustainability You Can Measure

• Compostable bamboo heads divert ~ 85 % of brush plastic.
• USB-C charging eliminates bulky docks—less e-waste, easier travel.
• Plastic free packaging

Serious Sonic Power

7 × more plaque removed along the gumline than with a manual brush—matching premium competitors without the fossil-plastic handle.

 

Battery & Portability

One charge = about 30 days of twice-daily brushing. Perfect for long trips or remote tramping huts.

 

How to Choose Your Sustainable Electric Toothbrush

 

1. Set your priority – plaque removal, gum care or pure eco impact.
2. Check head disposal options – can you compost or at least recycle?
3. Look for open charging standards – USB-C beats proprietary bricks.
4. Calculate true cost – add a year of heads to see the real spend.
   

 

FAQs

How do I compost the heads?

Pull out the nylon bristles, toss the bamboo collar into your home or council green-waste bin—it breaks down in 6–12 months.

Can I use Crescent Nest heads on other handles?

Yes, it is compatible with Philips Sonicare toothbrushes. 


Switching to a bamboo sonic toothbrush isn’t a token green gesture—it’s a genuine performance upgrade that keeps a dozen plastic handles out of landfill every year.

Brush better. Waste less. Smile brighter.
