Right at the end of my Invisalign treatment and have been given 4 options by my dentist to complete the treatment and be on my way:
1- removable retainer to wear at night (free)
2- Vivera retainer (apparently better and made by Invisalign) wear at night. (£300)
3- fixed wire top and bottom (£300)
4- fixed wire and the cheaper retainer (£400)
Which should I go for? Any orthodontic experience from any of you lovely mumsnetters?
