Invisalign treatment is one of the greatest developments of modern dentistry. It is the most effective teeth straightening treatment ever developed. Ever since it was introduced to dentistry,   it has transformed the teeth straightening procedure that was traditionally used by orthodontic specialists. It is more effective and powerful for fixing various orthodontic problems compared to traditional dental braces. But how long does it take Invisalign to work? You might be seeking an answer to this question. Well, this post will help solve your query but before we come to your query, let us throw some light on Invisalign treatment and clear dental aligners for better understanding. 

What is Invisalign Treatment? 

Invisalign treatment is a months-long dental procedure where a patient needs to wear a pair of Invisalign clear aligners over teeth for at least 20-22 hours a day during the treatment period. The Invisalign aligners gradually put pressure on misaligned teeth, resulting in getting the patient’s teeth in proper alignment after a certain period. During the treatment period, the patient needs to keep replacing its invisible teeth braces in short intervals because the aligners lose their tightness on teeth after a few weeks. 

What are Invisalign Clear Braces? 

Invisalign clear braces or Invisalign clear aligners are a pair of plastic-made teeth trays that are worn over teeth by an orthodontic patient for teeth straightening. They are an alternative to traditional dental braces that are made of metal wire and brackets. However, they are much more effective than them. 

Invisalign clear aligners are custom-designed by Invisalign specialists at the clinic so that they can perfectly fit over your teeth and work effectively. 

The Process of Designing Invisalign Dental Aligners

Invisalign dental aligners are designed by dentists in a strategic process. In this process, an Invisalign specialist first scans your mouth. He/she can take 3-D photos of your mouth or make a silicone mold of your teeth to get an accurate shape and structure of your teeth. The scanning of your mouth helps dentists to design a pair of Invisalign clear aligners that can fit your teeth perfectly. The designing process of Invisalign takes place in the lab under the supervision of Invisalign dentists and designing experts

How Long Does It Take Invisalign to Start Working? 

You know Invisalign is effective to fix various orthodontic problems, including:

  • Crooked Teeth- Teeth that are not in proper shape (bent or twisted teeth). 
  • Teeth Crowding or Overcrowded Teeth- Teeth that are erupted improperly or in a crowded way.
  • Misaligned Teeth or Malocclusion of Teeth- Abnormally aligned teeth. 
  • Overbite- Upper teeth overlapping lower teeth.
  • Underbite- Lower teeth extending over and covering upper teeth partly. 
  • Crossbite- Improperly lined up lower and upper teeth when the mouth is closed.
  • Open Bite- No connection between lower and upper teeth when the mouth is closed.
  • Gaps Between Teeth- Abnormal gaps between teeth.

But how long does it take Invisalign to work? 

According to Invisalign dentists, Invisalign treatment takes a maximum of 2 years to fix misaligned teeth which means a patient can get its misaligned teeth fixed in less than 2 years for sure. However, in some cases, Invisalign may fix the problem as quickly as 6 months. It heavily depends on multiple factors. 

The followings are different factors that determine your Invisalign treatment time: 

The Complexity of the Problem 

The complexity of the orthodontic problem that you address is the major factor in determining your Invisalign treatment time. No matter what orthodontic issue you want to address, the severity of that issue will decide how long you will have to wear Invisalign clear aligners. It could be anywhere between 6-24 months. Your Invisalign dentist can give you the right treatment time estimate for your case. 


Your age is another crucial factor that decides how long you will have to wait to get a pretty smile. Invisalign dental aligners work faster with kids and teens but they make their impact relatively slowly with adults and old people. However, this doesn’t mean that Invisalign braces are less effective with adults and teens. They are effective, but it is your dental muscles that increase your Invisalign treatment time. 

Being an adult, if you want to shorten your treatment time, traditional dental braces could be a better choice for you as they relatively work faster than Invisalign aligners. However, before choosing traditional dental braces, do not forget that they have certain disadvantages. 

How Compliantly You Follow Your Invisalign Dentist’s Instructions

When an Invisalign dentist gives you your Invisalign treatment plan, he/she also determines a set of instructions that you need to follow on a daily basis. If you do not follow those instructions properly during your treatment period, your treatment time will automatically increase by one month or more. You need to strictly follow your Invisalign treatment instructions to get rid of your dental problem as soon as possible. 

These are some of the crucial factors that decide your Invisalign treatment time. We hope now you will not need to search again for “how long does it take Invisalign to work.”
