Want to get straighter teeth? You might be interested in orthodontics, but there are several options you can consider. Clear aligners, like Invisalign or SimplyClear®, are great alternatives to braces. They use thin, plastic trays to shift your teeth, but how long will it take to get your results? Here is a quick guide on how long clear aligners take and how you can get an accurate estimate.

What Are Clear Aligners?

As a refresher, clear aligners are orthodontic trays that apply pressure to your teeth to move them. They are removable, unlike traditional braces, so you can take them out when eating. That said, you’ll have to make sure you keep them in 20 to 22 hours every day to move your grin as expected. Attachments often need to be placed for precise adjustments, and you’ll swap to a new set every week or so.

How Long Does a Clear Aligner Treatment Take?

It can take about 12 to 18 months on average to finish with clear aligners. Your time with them may be shorter if you have minor orthodontic issues and longer if they are more moderate. If you have a severe case and issues that need more in-depth work, then you may need another treatment to get the results you’ll feel your best in.

Is There Anything That Affects My Timeline?

As was mentioned above, your time with your clear aligners depends on a few factors. The only way to know exactly how long it will be is by talking to your dentist. They will do an oral examination to see exactly what’s needed. These are a few they will consider:

  • Your specific orthodontic issues will be the baseline of the length of your treatment. Minor crowding or gaps can often be corrected much faster than more severe ones. That said, some teeth are more stubborn than others, so progress checks will ensure everything is going as expected.
  • Your age may be considered, as adults have fully formed jawbones while teens don’t. That said, a few older patients have had relatively quick times before; it just depends on how your smile acts.
  • How compliant you are with your aligner routine can determine whether you have any delays or not. By sticking to the wear time and taking care of your teeth, you can stay on track.

In the end, the only way to know how long you will have orthodontic trays for is by talking to your dentist. They will look at your unique case and let you know the next steps to get the straighter smile you dream of.
