A full smile makeover can take one appointment or several months, depending on the treatments you get. Here are some example timelines:
Enlighten whitening takes two weeks.
Composite bonding takes one visit.
Porcelain veneers, including a trial smile, can take a few weeks, allowing the trial smile to be worn and previewed.
Some orthodontic (Invisalign) treatments take weeks but more complex treatments may take several months.
