How Long Does Invisalign Take To Work?
“Invisalign is A Clear Way to A Straighter Smile.”

Did you know that over 10 million people worldwide underwent Invisalign treatment in 2021? The reason why people prefer Invisalign over traditional metal braces is due to its comfort and discreet appearance.
However, those who undergo this treatment usually ask, “How long do I have to wear invisalign to straighten my teeth?” If you want to know the same, you’re at the right place. We will discuss the same.
How Long Does Invisalign Take to Straighten Teeth?
Since no two people are the same, the teeth alignment of every patient is different. That is why the average Invisalign treatment can vary depending on the complexity of the case.
For instance, the treatment for simple cases can be as short as six months, whereas complex cases, such as crowded teeth, take 12 to 18 months. However, you can see noticeable differences within 3-6 weeks of starting the treatment.
At United Smiles Dentistry, we provide different types of invisalign for different types of cases. The timeline for different types of Invisaligns is shown in the table below:
Version | Fixes | Length |
---|---|---|
Invisalign Go | Minor imperfections | 4 months |
Invisalign Express | Crooked front teeth | 3–4 months |
Invisalign Teen | Mild to severe | 12–18 months |
Invisalign Full | Mild to severe | 12–18 months |
What Factors Can Affect Treatment Duration?
Since no two cases are the same, the duration of Invisalign treatment depends on the patient. Here are the factors that can change the duration of your invisalign treatment:
- Crowded teeth: Severely crowded teeth require more time to align as compared to mildly crowded teeth.
Apart from that, dentists may also recommend using headgear or removing some teeth, especially in severe crowding. So, it is always good to schedule an appointment with your dentist to get an estimate for the duration of treatment.
- Gap in teeth: If you have significant gaps between your teeth, the aligners will need more time to close these spaces.
- Age: While the treatment duration depends on the teeth' conditions, age also plays a vital role. Younger patients often experience quicker results because their teeth and bones are more malleable. However, the condition is that they have to wear their aligners responsibly for at least 22 hours a day.
- The case's complexity: People with severe malocclusion or other complex orthodontic issues will require a longer treatment period. Simple cases, such as minor cosmetic adjustments, can be resolved quickly.
- The need for refinements: Sometimes, refinements are necessary to achieve the desired results. This might involve additional aligners to correct minor imperfections after the initial treatment, increasing the duration.
- Patient compliance: Wearing your aligners for the recommended 20-22 hours daily is crucial for the treatment to progress as planned. If you frequently remove your aligners or forget to wear them, your treatment may take longer.
Can You Reduce Your Treatment Period?
Yes, you can reduce your treatment period. Here is what you can do to speed up Invisalign treatment:
- Always follow the instructions given by your dentist. For instance, your dentist may ask you to wear your aligners for over 20 hours each day. So, make sure you consistently use those aligners as instructed.
- Take proper care of your aligners. Damaged or lost aligners can extend the timeline of your treatment. Visit your dentist for regular checkups and the replacement of aligners.
- Wash your aligners regularly. Don’t eat while wearing your aligners. Change the aligners at the right time.
- Avoid too much coffee and alcohol, as it can stain your aligners.
Your existing oral health issues can cause unnecessary delay in the treatment. So, make sure you take proper care of your oral health. Brush your teeth regularly and schedule your appointment with a reputable dentist for regular cleaning.

Frequently Asked Questions
Is Invisalign faster than braces?
Yes, invisalign provides faster results than braces. However, it will also depend on the severity of the condition. For complex malocclusions, braces may be effective and faster than invisalign.
Is Invisalign painful?
Yes, invisalign treatment can be painful in the beginning. This is because the invisalign aligners take time to adjust as per your jaw. So, sometimes, you may experience pain in your jawline.
Can Invisalign fix crooked teeth?
Yes, Invisalign can correct crooked teeth effectively.
How often do I need to change my Invisalign aligners?
You will need to change your Invisalign aligners approximately every 1-2 weeks, depending on your treatment plan.
