How long does Invisalign take to straighten teeth?


Invisalign is becoming an increasingly popular option for patients to straighten their teeth. Many patients prefer the subtlety provided by the clear devices; others prefer to not have braces on their teeth. Most people don’t know how long it takes for Invisalign to straighten teeth though, and that’s another great reason that you should consider Invisalign.

While the time can vary for every patient depending on their need, the typical course of treatment for an adult lasts about 12 months. When you compare that to the two years that it takes for braces – Invisalign becomes the clear choice.

While the most severe issues can take longer for Invisalign to correct, patients can see their issues resolved in as few as eight weeks.

Does Invisalign Take Longer to Work in Adults?

Some research suggests that the opposite of this is true. However, the difference may not be caused by the actual age of the patient, but how closely each patient follows their prescribed regimen. Teenagers tended to wear their Invisalign less religiously than their older counterparts. However, teenagers should also look into Invisalign’s product line developed specifically for them.

Typically, Invisalign trays are designed to be worn for 22 hours per day, so even small changes can take longer if patients aren’t following this guidance.

Your dentist can help work with you to understand how long you should expect to wear Invisalign trays. The time can vary depending on how much your teeth need to move, the complexity of moving your teeth appropriately, and the ability of your teeth to shift. Some patients have teeth that are easily moved into their proper location. Other people have very stubborn teeth that will take significantly longer to move the same distance.

Invisalign and Crowded Teeth

Very mild cases of crowded teeth can sometimes be fixed in as few as six months. With more severe cases, Invisalign can take longer. Your dentist may look into also using headgear, or you may look into the removal of some teeth to achieve the proper bite and smile.

Invisalign and Gapped Teeth

If you have a small gap, you may complete your Invisalign treatment in as little as eight weeks. However, many gaps have a tendency to revert if the underlying issue isn’t corrected, so many patients also require a retainer to make sure that their changes are permanent.

How Does Invisalign Differ from Braces?

Invisalign and braces are often used to treat many of the same issues, and there are many aspects of the Invisalign process that are similar to that of braces. One of these is the amount of time that you will need to visit your orthodontist or dental professional. Typically, braces require an adjustment every two weeks. Invisalign generally requires new trays every two weeks, so your visits should be roughly equivalent.

However, despite the similarities, Invisalign has many advantages. Invisalign trays are less prone to breaking. Additionally, getting a replacement tray doesn’t require a visit back to the orthodontist. You can simply get a new tray shipped directly to you.

Invisalign is seen by many patients as much more convenient. The trays are removable, that means that you can take them out to eat, speak in a public setting, or brush your teeth. While you should wear them for about 22 hours a day, it gives you some freedom to show off your improving smile!

Invisalign works more quickly than braces. Typical treatments for Invisalign are finished in about half the time as braces. This simply can’t be understated for patients who want to have their perfect smile as soon as possible.


If you are considering braces or Invisalign, schedule an appointment with your dentist today to discuss your options. Make sure to bring any of your questions or concerns to your dentist’s attention so that you can make the best decision to achieve your new smile sooner.
