4 Factors That The Affect Duration Of Invisalign Treatment

Invisalign treatment is one of the most popular orthodontic appliances used today for straightening teeth. This type of treatment works like traditional braces, but you can barely see them and they’re removable. Moreover, Invisalign treatment can take less time to realign your teeth compared to metal braces, which is how it has become one of the most preferred teeth aligner treatment today.

But exactly how long does treatment last?

Most patients can notice movement with Invisalign clear aligners after the first two weeks. However, the average duration for complete realignment is approximately 12 months. It’s also worth noting that patients will have to wear a retainer after the treatment to maximise treatment results. 

That being said, it’s important to know that every person’s needs and condition are different. As such, determining an exact timeline is best performed on a case-by-case basis.

For example, a patient who only needs minor corrections could complete treatment in just six months, while others might require triple the time.

Many factors contribute to the treatment duration, such as: 

  1. Gaps in Teeth

Gaps in a person’s teeth are often a result of tissue overgrowth or teeth that are too small in relation to the jawbone. Minor gaps will only take a few months to correct, while more severe cases can take up to 18 months. This time will also depend on how the teeth respond to treatment. 

2. Teeth Crowding

If your orthodontic issue is classified as minor teeth crowding, then your treatment might last for just six months. For moderate cases, it can take up to 12 months. For people with more severe teeth crowding, the duration of treatment can take more than 12 months. 

3. Patient Age

Your age can have a significant impact on the effects of treatment. Teens can expect faster treatment because their teeth tend to move faster than those of adults. However, that doesn’t mean that adults should expect longer treatment durations. It still comes down to how fast a person’s teeth move. Some older adults may see faster results than children. 

4. Compliance

Even if there are only minor teeth corrections to be done, if you don’t follow your orthodontists orders religiously, the treatment duration will take longer. Since Invisalign aligners are removable, some people may have the tendency to leave them off for longer than they should, while others tend to forget to put it back on. 

To get the best results, wear your Invisalign aligners for at least 22 hours per day or as prescribed by your orthodontist. You can always take them out when you have to eat, clean them, or brush your teeth. Keep in mind that you’re expected to wear them even while you’re sleeping, 


As you can see, several factors will influence the speed of treatment and its overall duration. More importantly, keep in mind that every person’s teeth are unique, so you can’t compare your progress with someone else’s. In any case, be confident that Invisalign treatment is highly effective and has given thousands of individuals the smile that they’ve always wanted.
