What does the length of my treatment depend on?

Answered byDr Ivelina Ivanova-Koycheva, Orthodontist (MSc)Master's degrees in orthodontics in Rome and in aligner treatment in Turin, international lecturerPublished on 12 November 2026

The length of treatment depends mainly on the following factors:

1. How complex the problem is – the bite, lack of space;

2. The patient's age;

3. Bone density, any metabolic conditions, pregnancy;

4. The patient's cooperation and motivation – wearing elastics, training the position of the tongue if needed, or correcting another harmful habit;

5. Keeping booked appointments;

6. Following instructions – not knocking off brackets, not losing aligners, etc.;

7. Keeping up good oral hygiene.

This answer is for general information. Your own case needs an examination by an orthodontist.
