What the evidence says
Our summary of the research, then the counts it rests on. Each count opens the search that returns it.
Chewies help fully seat trays, which matters for aligners to move teeth as planned. The benefit is practical and mechanical rather than proven in large trials.
The score is the one figure here we compute ourselves: a logarithmic blend of the three counts above (every indexed paper, the randomized trials, and the systematic reviews), with a trial or a review counting for more than an ordinary paper. It measures how much research exists on the topic, not whether a product works for you. The same method grades every topic on the accessories index.

What to watch for
Reusable, but replace them when worn. They are not a fix for aligners that genuinely do not fit: if trays will not seat, contact your provider.
