How Long Does Invisalign Take on Average?
On average, Invisalign treatment lasts between 12 to 18 months. However, treatment time can range from 6 months for minor adjustments to up to 2 years for more complex cases.
It's important to keep in mind that the duration of treatment will depend on the following factors:
The Complexity of Your Case
The more complex your dental issues are, the longer it may take to correct them. Some of the most common factors that can impact treatment duration include:
Severe Misalignment: If your teeth are significantly misaligned or if you have a complex bite issue, treatment may take longer as more movement is required.
Crowded or Gapped Teeth: If you have crowded teeth or significant gaps between them, Invisalign may take longer to achieve the desired results.
Overbites or Underbites: Correcting a severe overbite or underbite may require additional time as it involves moving the jaw in addition to the teeth.
Your Age and Teeth Condition

Older adults may require slightly more time than younger patients to see results because teeth can become more resistant to movement with age.
Additionally, if your teeth and gums are already in good health, you may experience faster results.
However, if you have gum disease or other dental issues, treatment may be extended as these conditions must be treated first.
Invisalign offers a highly customized approach to teeth straightening, which means the treatment time can vary greatly from person to person.
Unlike traditional braces, which often require adjustments at regular intervals, Invisalign relies on a series of aligners that are changed approximately every one to two weeks.
The aligners gradually move your teeth into position. Although the process is generally quicker than traditional metal braces, it still depends on a few key factors.
Some people may experience faster results with Invisalign, while others may require more time.
Understanding these factors will help you get an idea of how long your Invisalign treatment will take and how to ensure the best outcome.
How Well You Follow the Treatment Plan
Your commitment to wearing your aligners as instructed plays a huge role in how quickly your treatment progresses.
Invisalign aligners must be worn for 20-22 hours a day to be effective. The more consistently you wear your aligners, the faster your teeth will move into their desired positions.
If you neglect to wear your aligners for the recommended amount of time, your treatment may be delayed.
Additionally, skipping appointments or failing to follow your dentist's advice could result in longer treatment times.
The Invisalign Treatment Process: A Breakdown
While the duration of Invisalign treatment can vary, the process typically follows these steps:
Step 1: Consultation and Customization

The first step in your Invisalign journey is to schedule a consultation with a certified Invisalign provider.
During this appointment, your dentist will assess your dental needs and determine whether Invisalign is the right option for you.
If you are a candidate, they will take impressions, X-rays, and photos of your teeth to create a customized treatment plan.
The dentist will also create a digital 3D model of your teeth, which will be used to map out how your teeth will shift throughout the treatment process.
Based on this model, Invisalign will manufacture your first set of clear aligners.
Timeframe: The consultation typically takes about an hour, and the aligners will be ready within 1-2 weeks.
Step 2: Wearing the Aligners
You will begin wearing your first set of Invisalign aligners, and every two weeks, you will switch to the next set of aligners in the series.
Each set of aligners is designed to gently move your teeth closer to the desired position.
While wearing your aligners, it’s crucial to stick to the following:
Wear aligners for 20-22 hours a day.Only remove them to eat, drink, brush, and floss. Visit your dentist for check-ups every 6-8 weeks to track progress and receive new aligners.
Timeframe: This process generally takes between 12 and 18 months, depending on the complexity of your case.
Step 3: Final Results and Retainers
After completing the required sets of aligners, you’ll achieve your final results—straight teeth and an improved smile.
However, to ensure that your teeth stay in their new positions, you will need to wear a retainer.
Retainers help to hold your teeth in place while the bone and tissue around them stabilize. Your dentist will provide a retainer to wear after the treatment is complete.
Timeframe: You will typically need to wear your retainer for a period of time, with adjustments to the wear schedule as recommended by your dentist.
Factors That Can Speed Up Invisalign Treatment
While Invisalign treatment usually takes between 12 and 18 months, some factors can potentially speed up the process. Here are a few tips to accelerate your treatment:
Consistency in Wearing Aligners

The more consistently you wear your aligners, the faster your treatment will progress.
Make sure to wear them for the recommended 20-22 hours a day and only remove them for meals, snacks, and oral hygiene.
Take Advantage of AcceleDent or Propel Systems
Some patients choose to speed up their treatment with a device like
AcceleDent or Propel, which stimulate bone movement to accelerate the teeth straightening process. Consult with your dentist to see if these treatments are right for you.
Regular Check-Ups and Progress Reviews
Maintaining regular check-ups with your Invisalign provider is essential.
During these visits, your dentist will monitor your progress and make adjustments as needed to ensure you’re on track for the best results in the shortest time possible.
