Well thanks to your alls advice I had an NTI device
made.

I had to have one made to fit lower teeth tho

Have worn it three nights now and so far so good. Took
a bit to get used to it tho.

Question.... this device is small. Hard to handle.

What is best way to clean it daily?  Maybe use some
foaming denture cleaner?

My dentist said it might not be wise to brush it as its
made of Lexan and might scour it. True?

Thanks for any advice
