How Long Does Invisalign Take?

May 30, 2024

All braces are meant to straighten teeth differently, with varying treatment durations. Most patients prefer quick results with very minimal invasiveness. Luckily, modern orthodontics offers faster solutions compared to the past.

One popular option is Invisalign, known for its nearly invisible clear aligners. Curious about how long Invisalign treatment takes? Read on to find out!

What is Invisalign?

Invisalign is a modern teeth straightening method that uses clear aligner trays instead of brackets. These aligners gradually move your teeth, requiring frequent changes similar to the adjustments needed for traditional braces.

The process includes a series of aligners, or “trays,” each moving teeth between 0.1mm to 0.25mm before being replaced with a new one. Depending on your case, you might need between 25 to 40 trays to achieve perfectly straight teeth.

How Long Does Invisalign Take to Straighten Teeth?

How long Invisalign takes to straighten teeth varies from individual to individual, but generally, the treatment lasts around 1 to 1 and ½ years. Yes, there are people who start noticing a difference in just 2-3 months of wearing the aligners.

How Many Hours a Day Are Recommended for the Best Results from Invisalign?

You should wear your aligners for at least 22 hours a day. Since you can’t brush your teeth or eat with them in, you can’t wear them every minute. Try to keep them out of your mouth for no more than 2 hours a day.

Following this advice will allow you to receive not just faster but also better results with Invisalign.

Is Invisalign Quicker Than Braces?

Braces straighten teeth in different ways, and some work faster than others. Invisalign is usually the quickest option, often used for minor cases. Typically, you’ll need about 20-30 sets of aligners over 6-8 months.

With fixed braces (metal and lingual), you need monthly appointments to adjust them. But with Invisalign, you don’t need these monthly visits because the aligners do the work without needing new wires.

Remember, treatment varies for each person. While Invisalign is often the fastest, your orthodontist will recommend the best option for you, whether it’s braces or Invisalign.

Reasons Why the Timeline Might Be Different for You

Every individual’s mouth is unique, like a fingerprint; this is why the time needed for braces varies. Some people finish in 6 months, while others may take 18 months.

  1. Gaps in Teeth
    Minor gaps are obviously quicker to fix than huge gaps caused by tissue overgrowth or small teeth. If you have huge gaps in your teeth, Invisalign treatment can take more than a year.
  2. Teeth Crowding
    If there’s minor crowding, then it can be fixed within 6 months, but severe crowding takes longer. Severe cases may require additional treatments before Invisalign.
  3. Compliance
    As we mentioned above, wearing aligners for at least 22 hours a day is important. Non-compliance can delay treatment, as teeth may revert to their original positions.
  4. Age
    Invisalign works faster for teens due to their ongoing growth, but older adults can also seek quick results with compliance.

The Bottom Line

So, how long does Invisalign take to straighten teeth? It all depends on your specific dental situation. For minor issues, the treatment plan will relatively be short. However, if your teeth need more significant correction, expect the process to take longer.
