Disclaimers:
Links to individual products, which is what I used on my site originally, often are unreliable and it's hard to check each individual listing to find which links work and which do not. I include search terms so you can find what is available and works for you. :)
I understand the issues with using Amazon, but I believe in the "no ethical consumption under capitalism" rule as well and Amazon is accessible for more disabled individuals. I have a section for other places if you want to support those instead!
Long chew necklaces -- good for people who use back teeth to chew
Feather pendant (very professional looking!)
Non-silicone chewies
