How Long for Invisalign® to Work?

Wondering how long Clear Aligners like Invisalign® take to work? Here’s everything you need to know:

Does the idea of metal braces put you off? Braces are effective, but they’re quite the commitment. And they’re not always ideal, depending on the individual. If you’ve been considering clear aligners (nearly invisible treatment), you might be wondering how long aligners like Invisalign® take to work.

Invisalign® is just one of many tools available to your orthodontic provider. An initial assessment or consultation will help determine the best course of treatment for you. There are also several different aligner brands available. Invisalign® just happens to be one of the best known. By far the most important choice to make is that of clinician. We encourage you to find a skilled and experienced specialist orthodontist to diagnose and treat your unique case.

If right for you, clear aligners like Invisalign® are an attractive alternative to metal braces and the solution can be just as effective (depending on the specifics of your case). In many cases, the aligners are able to address overcrowded, misaligned and crooked teeth. The aligner mouthpieces looks similar to teeth-whitening trays, and you wear them for 22 hours a day. Aligners have a similar straightening effect to braces, but to the casual observer, it’s almost impossible to tell you’re wearing the trays. Clear aligners can be preferable to metal braces in some cases.

The Treatment Procedure

Now, we need to understand how aligners like Invisalign® work. The procedure involves a series of plastic, removable aligners that you wear in incremental sequence. You’ll start with your orthodontist creating a customised treatment plan and profile, which involves:

• Photographs of your face, smile, profile and teeth

• A 3D scan of your teeth

• Examination of your X-ray and teeth

• Determining if you’re a candidate for clear aligners such as Invisalign®

• Writing up a recommendation

If you’re a good fit for the treatment and decide to go ahead with this option, your orthodontist will create a 3D computerised model in order to plan the aligners. This helps your orthodontist figure out where your teeth should to move to. Each misaligned tooth moves in stages. The amount of stages needed is very case-specific. Depending on your unique situation, you may need anything from around 6 – 30 aligners for your treatment to be effective. This important difference will affect how long the aligners take to work for you.

Each of the aligners will move your teeth up to a third of a millimetre before you pop in the next aligner. In short, you should expect to change aligners every week or two. If you would like to ensure your teeth are moving as fast as possible, you may be interested in using our Dental Monitoring Smart Phone App which scans your teeth, and allows you to progress to the next aligner if your teeth have already moved.

Your Role in the Process

Of course, your treatment requires supervision by a clinician. But, once it is underway, you have a certain amount of responsibility too. For optimal results, it’s up to you to fully commit to the customised plan and wear your aligners the way your orthodontist suggests.

The duration of aligner treatment will vary from one person to the next, but you will need to wear your aligners for about 22 hours each day throughout the process.

You can remove the aligners for short periods, usually to eat and drink (anything other than cold water), or to brush and floss. Failure to comply with your orthodontist’s directions can negatively affect how long aligners such as Invisalign® take to work, including the overall time you will need to wear the aligners.

How Long Does It Take for Treatment in Aligners like Invisalign® to Work? How Long is the Treatment Time?

Now that you know what’s involved in clear aligner treatment, let’s look at how long it all takes to work.

As for estimating the length of treatment, the timing comes down to complexity, as well as treatment goals. If your case isn’t complicated, you can expect treatment to take around six months. Those patients who have more complicated orthodontic needs could undergo up to around two years of treatment.

One good rule of thumb to follow is that the average treatment time is about 12 months. But, here’s one of the great things about clear aligner treatment – you’ll begin noticing the difference within just a few weeks of treatment. Sure, the results may seem minimal to begin with, but you can usually expect noticeable changes within 4 to 6 weeks of starting your treatment. Just remember, though, that each and every patient is different. You might see your changes a lot quicker than your friends who are undergoing treatment in aligners like Invisalign®, or you may feel as though it’s taking longer to see a difference in the alignment of your teeth.

How Long Should You Wear Your Aligners for Each Day?

We’ve already mentioned that the ideal amount of time to wear your aligners for each day is 22 hours. Remember, though, that you can (and should) take them out to eat and brush your teeth, as well as while playing sport and swimming. Other than that, you should be prepared to commit to consistently wearing your aligners. Otherwise, you’re likely to prolong how long the aligners take to work and you won’t achieve your desired outcome as quickly.

When you first receive your aligners, your teeth and jaws might feel little bit tender. That’s entirely normal and is usually mild. Wearing the trays is sure to feel unnatural at first, and it’s tempting to take the aligner out. But, don’t. Make that commitment to wearing your trays for the required amount of time each day. After a few days, the soreness does subside, and you get used to wearing the aligners.

How Can You Shorten Your Treatment Period?

Here’s another big benefit of clear aligner treatment – there are a few things you can do to ensure your treatment time is as short as possible.

• Always follow the instructions that your orthodontist gives you. If you’re told to wear the aligners for a minimum of 22 hours each day, make sure you follow through and commit to regular wear as instructed.

• Secondly, take proper care of your aligners. Damaged or lost aligners can cause treatment delays. If an aligner gets cracked, tell your orthodontist so that they can prepare a replacement tray for you.

• Problems with general dental health can can cause delays and other issues that can extend overall treatment time. Keep up your regular checkups and cleanings with your dentist, and be sure to brush out any food particles and plaque that could hang onto the aligners. You should give your aligners a deep clean at least once or twice a week to keep your trays working properly and your teeth in good health.

• Remember to change the aligners on the right date and take them with you if you are planning on travelling.

• Finally, remember that there is a Remote Monitoring App available which allows you to scan your teeth at home. The scan will feed back information to your orthodontist and you may be able to progress through aligners faster if your teeth are moving quickly.
