There’s so much to adore about sweet-but-never-saccharin, holiday-perfect Stranger Than Fiction: Will Ferrell’s all-around awesomeness, the groovy soundtrack, some screen time from Arrested Development’s amazing Tony Hale. But there’s a tiny detail in the movie’s first few moments that completely wins our little Earth-loving hearts: That toothbrush with which lead character Harold Crick obsessively brushes his choppers for the same number of strokes each and every boring day? It’s none other than the ThisNext-featured Preserve Toothbrush from Recycline, Inc. We made that discovery at the blog Vestal Design, who explain that the Preserve’s “made from at least 65% post-consumer recycled polypropylene, from Stonyfield Farms yogurt containers.” What’s more, “the Stonyfield-origin plastic is acquired via consumers who wash and mail back clean containers at their own expense to Stonyfield.” And, ThisNexter Heidrun adds, “when you are done, you send the toothbrush back to the company for further recycling, in a postage paid mailer which they supply.” Heidrun digs the brush’s lack of superfluous features like “rubber grips, plastic decoration, glow-in-the-dark swirls,” while pinkmirage is all about the “awesome design [that] allows you to reach those back teeth.”

Another planet-positive choice, the Junior Eco-Toothbrush comes recommended by Tracy. “When these toothbrushes are worn out, you just replace the head, not the whole thing,” says Tracy. “Less to landfill!”

Although they’re not especially eco-friendly, electric toothbrushes are sometimes your best bet for polishing your pearly whites. Joe and esh both brush up with the Oral-B Triumph ProfessionalCare Power Toothbrush—albeit with different models. Joe recently switched from Sonicare to the 9400 ProfessionalCare and found that new product takes less toothpaste to operate but still makes for a cleaner mouth. Plus it’s got “a ‘floss action’ head, which has got to be good for my problematic gums.” Esh prefers the 9450 model, which he dubs “the winning power toothbrush.” Some tips for optimal operation:

“You can probably toss the ‘polishing’ and ‘whitening’ brushes. They can’t sell a tooth product on the market today without claiming it does whitening (not even chewing gum).

I avoid the default high speed setting and push the mode button once to get to the slightly slower speed. It’s still all the power I need to get my teeth clean and some day when the toothbrush starts to seem a bit sluggish (and they all do) I’ll start using the high setting and feel like I have a new brush.”

Unlike Joe, Debe Gray and Jean are both fans of Sonicare, especially the Elite 9500 model, which Jean describes as “pretty freaking amazing. AND kudos to Sonicare for cleaning up/streamlining their design.” Debe, meanwhile, tells us: “I love, love, love this. My husband got me one for Christmas two years ago. It makes your teeth nice and smooth, as though you’ve just had a dental cleaning.”

And for those unfortunate moments when your teeth are wearing little sweaters and there’s nary a toothbrush in sight, keep a pack of Oral B Brush Ups handy. “This tooth brush and toothpaste in one wins my vote for best invention of the year!” raves kibibisprings who recommends the Brush Ups for “those times when a breath mint isn’t enough.”
