Fabater Plaque Disclosing Agent, 60ml Dental Plaque Indicator with Scale Cup, Oral Tartar Test Examination for Kids or Adults Teeth, Plaque Identifying, Care About Your Dental Hygiene

This is so great but its all written in Chinese and dont sure what it says on the instruction but it does a good job by just taking small amout to show before and after and missing part. It was fun to do that with my kids.

It does what its suppose to do. Not bad for the money... easy to use.

Everything in this is in Chinese so when you receive it, one must look on this page to get any instructions. We followed the instructions from this page and it just stains everything. We did it a couple of times on the same night. First, we brushed out teeth and then used the solution. After that we then brushed our teeth again followed with the solution again. It looked exactly like it did before. So the only thing it can do is stain everything, your teeth, lips, any skin that it gets on. It does not actually show where you are not brushing. It also tastes disgusting so kids are not going to want to use it. You will also want to clean it up immediately because it will stain your sink as well if it is not cleaned immediately. I thought I had but then I found a small stain today and it doesn't want to come up. We will not be using this solution ever again!

Struggled with having the kids brush their teeth properly. This helped.

The instructions are all in Manderin and I had to use ChatGPT to translate to understand dosing and usage. The translation came back saying this product is related to blood glucose testing. There could be a misunderstanding or the product might be different from what was expected.
