How It Works

Orthodontic treatment duration depends on the type and severity of dental issues, treatment method, patient age, and compliance. Teens typically finish faster because their bones are still growing and teeth move more easily.

The Formula

Duration = Base Months x Severity x Treatment x Age x Compliance
Range = Duration x 0.8 to Duration x 1.2

Variables

  • Base — Average months by issue: Crowding 18, Spacing 12, Overbite 20, Underbite 24
  • Severity — Mild 0.65x, Moderate 1.0x, Severe 1.4x
  • Treatment — Braces 1.0x, Invisalign 0.95x, Accelerated 0.6x

Example

Moderate crowding with braces in an adult with good compliance: 18 x 1.0 x 1.0 x 1.0 x 1.0 = 18 months (range: 14-22).

Tips

  • Keep all adjustment appointments to stay on schedule
  • Broken brackets or lost aligners can add weeks to treatment
  • Accelerated orthodontics can cut treatment time by 40% but costs $1,000-$2,000 more
  • Rubber bands (elastics) are critical for bite correction - wear them as directed
  • The retention phase is just as important as active treatment
