onirevdental care kit -

Hi can i use this on a bottom back tooth tjst has slightly broken at the back of the tooth.

How does it last with brushing and things?

Can this be used to hold a fixed retainer in place? One spot of glue has come off on one side of mine.

I've just chipped a tooth and it is rubbing against my tongue causing pain on my tongue. Will this product cover it until my dentist appointment
