What changes the recommendation
Four findings can matter more than appliance preference
An adult may begin with a strong preference for aligners or braces. A useful examination tests that preference against the starting condition, the movements required, the health of the supporting tissues, and the daily work each option requires.
Starting oral health
Active decay, gum inflammation, bone support, worn teeth, and existing restorations may need attention before or during orthodontic treatment.
Movement and bite complexity
Rotation, root movement, vertical correction, jaw relationships, and the way the bite closes can change which mechanics deserve consideration.
Daily adherence
Aligners depend on prescribed wear and safe storage. Braces remain fixed but require careful cleaning, food choices, and protection from damage.
Monitoring and contingency plan
Ask how progress is checked, what happens if the first plan is not tracking, when refinements are used, and when a specialist opinion is appropriate.
Take a written decision summary home
Before choosing, ask the provider to summarize the recommended appliance, the clinical reason, expected responsibilities, monitoring plan, likely contingencies, retention plan, and complete fee scope. That makes a second opinion easier to compare.
