One of the most common questions from patients considering Invisalign is: how long will treatment take? The honest answer is that it depends — but there are some useful guidelines.
Average Treatment Times
For mild cases — minor crowding or slight spacing issues — Invisalign treatment can take as little as six months. Moderate cases typically take twelve to eighteen months. More complex cases may take up to two years or longer.
Factors That Affect Treatment Length
The complexity of your case is the biggest factor. Compliance is also crucial — Invisalign aligners need to be worn at least 20-22 hours per day to work as planned. Patients who remove their aligners too frequently will see extended treatment times.
Wearing Your Aligners Consistently
Unlike braces, Invisalign aligners are removable. Commit to wearing them as prescribed and your results will come faster. Most patients find the aligners comfortable enough to wear all day and night with ease.
Aftercare and Retention
After your final aligner, you will need to wear a retainer to maintain your results. Without retention, teeth naturally tend to shift back toward their original positions over time. This is true of any orthodontic treatment.
