Is there warranty on this? as for the black set there’s small black pieces coming off as i doing the exercises. looks like pepper as i spit out.

I experienced very similar defects. Which is part of the reason I discontinued use.

I wonder what they do with returns? Very afraid of being sold a returned product. Anyone know?

Hi, our returned items are disposed by Amazon's warehouse team so that no returned item is ever delivered to a new customer. You can use our items with ease of mind.

if my front four teeth on the top are veneers can I still use this product?

Since our products are used with the molar teeth your front teeth veneers should not be an issue. However, we would advice you to be extra careful while using the jaw exercisers and to always position them correctly on your molar teeth.

Is it ok to use this with a dental crown on one molar tooth?

Yes, these can be used with crowns.
