Invisalign vs braces retainers
Clear aligners and fixed braces both move teeth through controlled force, while retainers hold the result after active treatment.
The short answer
Clear aligners use removable thermoplastic trays made for a sequence of movements. Fixed braces use bonded brackets and archwires. Both require retention after active tooth movement.
How does orthodontic force allow teeth to move safely?
Orthodontic force changes the periodontal ligament and surrounding bone so teeth can move. Aligners apply programmed contact through tray surfaces; braces transmit force through brackets and wires.
What should you assess before choosing an orthodontic appliance?
An orthodontist should assess the bite, jaw relationship, photographs, and scans or impressions before choosing an appliance. Clean around appliances and use the prescribed retainer after treatment.
When do braces or aligners need prompt dental review?
Seek review for persistent pain, a loose bracket, sharp wire, cracked aligner, gum swelling, or a retainer that no longer seats. Do not force a damaged appliance.
What should you ask about movements and bite changes?
Ask which movements and bite changes are needed and whether aligners can deliver them. Ask about cleaning, attachments, refinements, and retainer design.
Frequently asked questions
Could this have more than one cause?
Yes. Several oral tissues or materials can produce similar symptoms, so examination may be needed to distinguish them.
What should I record before an appointment?
Note when it began, where it occurs, what triggers it, and any swelling, bleeding, sensitivity, discharge, or appliance change.
