I have had separate assessments for Invisalign and Incognito lingual braces to correct an overlap of upper front teeth and misalignment of lower front teeth. Both assessments have come back saying that four teeth need to be extracted – one in each of the four ‘corners’ of the mouth – prior to fitting of the appliance in order for it to work. This seems rather drastic and I cannot imagine that the gaps left by the removal of such large teeth will be closed by the realigned teeth, although the orthodontist who did the Incognito assessment has said they there will be no gaps at the end of treatment (which could take up to 22 months). I’ve booked to have the extractions done next wek, but I’m really still not very happy about having perfectly healthly teeth removed for this purpose. Does it sound right that I have to take such drastic action to get the smile that I want? (I’m in my 40s).
