Deciding to pursue orthodontic treatment is a positive first step toward better oral health. However, the choice to straighten your teeth with Invisalign may require ample research and discussions with your orthodontist. Although these clear trays are popular because of their transparency and subtlety, a common question you might ask is “How long does Invisalign take?” Read on to discover what kind of timeframe is “normal” for this type of treatment and how it can vary from person to person.

What is the Average Timeframe for Invisalign?

The average length of time for Invisalign treatment is 12-18 months. However, it’s important to remember that each person is different, so while some may finish within one year, others may require up to 24 months (or more).

What Factors Can Cause Invisalign Treatment to Fluctuate?

There are many reasons why the timeframe for Invisalign can vary. During your initial appointment with your orthodontist, you can expect them to go over the details of your treatment plan, including how long they expect you to need aligners to straighten your teeth.

The time you spend wearing clear aligners can depend on:

  • The severity of your dental problem – It is much easier (and faster) to close a gap between teeth than to address a severe overbite.
  • How well you adhere to treatment guidelines – Wearing Invisalign requires that you follow the 20-22-hour rule. This means you must wear your trays for this amount of time each day if you don’t want to suffer a setback.
  • How well you take care of your aligners – Protective cases are highly recommended while wearing Invisalign, as they minimize the risk of damage and loss. If you accidentally break an aligner or lose one, you can potentially add more time to your overall treatment, depending on what your orthodontist says when looking at your tooth progression.
  • Your age – Teens may not be required to wear these aligners as long because their teeth tend to move faster than adults.

Do not be discouraged if you discover that you need Invisalign longer than the average timeframe. Remember that your pursuit of a straighter smile requires patience. Once you see your results in the end, you won’t regret a single minute of your treatment.
