My dr. recommended a clear invisalign retainer but for my lifestyle (i am a flight attendant and can't easilly remove my retainers for eating)i feel a permanent retainer would be best. can i make the switch? the only time i take them out is to brush and t

Unknown: Your dentist felt that the Vivera retainers were best for your specific treatment, but you feel otherwise. You'll have to discuss your desires with them. If it is agreed that a fixed lingual wire will work equally as well for your post treatment retention, then I'm sure it can be placed for a nominal fee.

Yes, but: if you are in retention phase and have been for several weeks you should only need to wear them at night (during sleeping hours).

Pros and cons: There are pros and cons to every type of retainer. Some are more retentive, or more esthetic, r more functional, than others. The only one who would know what's best for you is your Dentist or an Orthodontic Specialist. This is not a question that we can answer in this forum without physically examining you.
