I received an upper arch set from dentist on Aug. 30th 2021. It doesn't fit well, does not snap in and slips. The teeth are way larger than my natural ones were and look like Halloween teeth. The concept is great and would have been a lovely solution but these just don't look or feel customized. My dentist says there is no warranty although the brochure states there is a one year warranty.
Also even though I clean as instructed they are stained already.
