Tacoma Invisalign doctors

Since you had only worn one aligner for 3 days, it is likely best to go back to the most recent aligner and contact your dentist to have them remake the lost aligner.  Had you been past one week in the aligner, you could probably fudge and move to the next one, but with only 3 days in you may compromise the case.  It MIGHT work, but you would assume all of the risk should it not.

In years past it was routine to extract teeth when doing orthodontics.  Times have changed and removal of teeth is only in extreme cases.  Invisalign allows us more control of tooth movement and often allows us to avoid extractions.

The photos are hard to read, so I can't really comment on what you would need, but I would assume extractions would not be likely.

Until the dentist gets the ClinCheck (the computer treatment plan), they don't know how many aligners/trays are needed for the case.  Until then, only a range of fees can be given.

However, I strongly suggest that you be aware of all costs before starting.  This will avoid any surprises.
