Smile Aligners vs Straight Teeth Direct
Starting price, treatment length, supervision, FDA safety record and full spec sheet for Smile Aligners and Straight Teeth Direct, side by side. Every figure links to the source that states it.
Smile Aligners (DayNight (dual or single arch), NightFit (dual or single arch))·Straight Teeth Direct (StraightBox)
Blue marks the lower price only where every compared price is quoted the same way (a monthly price in US dollars); prices quoted in another currency, as a one-time fee or as a provider-set range are shown exactly as stated and never converted. Adverse-event figures are raw counts of reports filed with the FDA, not rates (what the reports mean). Each spec value opens that brand's spec sheet, and its numbered sources verify the specs as a set. None of this is a recommendation: the right choice depends on your case, your budget and, above all, an in-person exam by a dentist or orthodontist.
