how long does invisalign take to straighten teeth

Thanks to Invisalign technology, adults as well as teenagers can embrace teeth straightening without the hassle of traditional metal braces.

It's hard to sign up for a year or so of a mouth full of metal wires and brackets as an adult, even if your crooked smile makes you self-conscious.

Though you may be interested in using Invisalign to straighten your smile, you may not know much about it. You probably want to know how long does Invisalign take to straighten teeth.

Read on to find out more about this exciting technology, and to answer your questions. 

Invisalign Treatment

Did you know some evolutionary scientists believe that our crowded teeth are a result of evolution? It's true.

The study of ancient jaws and teeth shows far fewer issues of crooked, crowded, or decayed teeth. Evolutionary scientists relate this to a lack of mechanical stress. As we have grown to eat softer, more processed foods, our teeth wear less and our bites weaken.

In other words, our jaws are meant to support teeth that experience significant wear and tear from hard foods. Think about your wisdom teeth. These teeth, now commonly extracted, once served a purpose.

These orthodontic issues are epidemic in modern society where nine out of ten people experience misalignment and malocclusion.

The first dentists to study this developed metal braces to help straighten your teeth and that technology exists still today. Though many people, adults especially, find braces to be a cumbersome and embarrassing experience.

Thankfully the recent invention of Invisalign treatment helps people gain the confidence of a straight smile with a clear, unobtrusive treatment. 

Wearing An Invisalign

Invisalign is a clear, plastic form of braces.

These aligner trays fit over your teeth and help move them into place much like traditional braces. The advantage being, Invisalign is not obvious to others, thus reducing the social anxiety associated with teeth straightening treatment.

Another major advantage of choosing Invisalign treatment is that, unlike braces, they can be removed for eating, brushing, and flossing.

A huge hassle that comes with braces is eating. There are foods that notoriously get caught in braces. Should you choose traditional braces to straighten your teeth, you can say goodbye to broccoli, pretzels, and chewing gum.

And because eating is problematic with braces, so is maintenance and cleaning. Food particles that get stuck in your braces are broken down by bacteria and causes halitosis and bad breath.

Braces require extra care to keep clean. Water flossers, toothpicks, and dental floss will become ever-present tools (you should floss regardless).

With Invisalign, you can eat what you like without fear of bad breath. The added benefit of these removable trays is ease and comfort with your normal dental care routine.

Most patients see noticable results after a few weeks. The average Invisalign treatment time is 6-12 months. How long to wear Invisalign is ultimately determined by a few important factors.


When your doctor prescribes antibiotics, do you take the full cycle? Or do you stop once you start to feel better?

One of the most major factors in all healthcare success is patient compliance. Your doctor or dentist prescribes a very specific treatment plan for a reason, and you will only see success if you follow it.

You must wear Invisalign trays 20-22 hours per day to ensure success.

Crowded Teeth

Crowded teeth is usually a genetic condition where your teeth are too large for your jawline and push together.

How long does Invisalign take for crowded teeth? It depends.

Minor cases of tooth crowding results in a 12-18 month Invisalign treatment plan. Severe cases of tooth crowding from a misaligned jaw may require corrective surgery or tooth extraction before starting Invisalign.


Gaps in teeth, known as Diastema, are the opposite of crowded teeth.

Gaps are often the result of teeth that are too small for the jawline. There are other factors that cause gaps.

These gaps form from habits as a child such as thumb sucking or an incorrect swallowing reflex.

They also form due to a too large labial frenum. This is the tissue connecting the inside of your upper lip to your gums.

These cases often take up to 18 months of Invisalign treatment.

Severe gaps require extra treatment. Your dentist may prescribe bonding procedures or veneers to close these larger gaps.


As is the case with many other ailments, the longer you wait the harder it gets. This is why many doctors recommend tonsil extraction for younger patients. Older patients take a lot longer to heal.

Ultimately, Invisalign treatment and age is a determination of the health of your mouth and your bone density. Younger mouths are often healthier and bone density is rarely an issue.

Invisalign treatment is not recommended for younger teens. The sweet spot for success is usually late teenagers and young adults.

Don't let that scare you away. If you are older, Invisalign will still be successful. Your treatment plan may take longer because the older you are, the longer your teeth take to shift. 

Invisalign Might be Right for You

Don't be afraid to smile. Don't let your self-consciousness or embarrassment keep you from displays of warmth and generosity of spirit.

If you desire straight teeth but do not want to deal with the hassle of braces, Invisalign might be right for you.

How long does Invisalign treatment take to straighten teeth? Given that after you complete it you will live the rest of your life with a beautiful smile, not very long at all.
