Understanding the Invisalign Process

Invisalign, a revolutionary approach to orthodontics, has transformed how we think about natural teeth straightening. This innovative treatment uses a series of custom-made, transparent aligners that gradually move teeth into position. The Invisalign process is popular for many due to its subtlety and comfort, but what does it entail? Let’s break it down:

  1. Initial Consultation:
    This is the first step, where you meet with your dentist to determine if you’re a suitable candidate for Invisalign. Your qualified dentist will examine your oral health and discuss your dental goals.

  2. Custom Treatment Plan:
    If you’re a good fit for Invisalign, your dentist will create a custom treatment plan, which involves taking photos, x-rays, and advanced computer imaging technology, of your teeth to create a 3D image. Using this image and advanced technology, your actual dentist can map out and tell you the approximate duration of your therapy and the precise tooth movements.

  3. Receiving Your Aligners:
    You’ll be called for another appointment once your aligners are ready. Your dentist will see that the aligners fit well and will guide you on how to wear and care for them.

  4. Wearing Your Aligners:
    You must wear your aligners for about 20-22 hours daily, removing them only when you eat, drink, brush, and floss.

  5. Regular Check-ins:
    Every six to eight weeks, you’ll have a check-in with your dentist to monitor your progress. You’ll also receive your next set of aligners during these appointments.

  6. Completion of Treatment:
    Once you’ve completed all your aligners, your treatment is complete! However, you’ll likely need to wear a retainer to maintain your new smile.


The Invisalign process is a journey, but patience and diligence can lead to a beautiful, confident smile.

Average Duration of Invisalign Treatment

Invisalign offers a nearly invisible and removable aligners option for teens and adults to address various orthodontic issues. But one question often arises: “How long does the average Invisalign treatment last?”

As with many dental treatments, the duration of treatment varies based on the patient’s circumstances. However, industry standards and expert opinions suggest that the average treatment time of Invisalign treatment typically ranges between 12-18 months. This timeline is based on patients following the recommended guidelines of wearing their aligners for 20 to 22 hours daily.

But it’s important to note that this is just an average. Some patients may find that their treatment is shorter, possibly around 6-18 months for teens and adults, especially if their dental issues are minor. On the other hand, more complex cases may require a longer treatment duration, potentially extending beyond 18 months.

Factors Affecting Invisalign Treatment Duration

When considering the path to a straighter smile, it’s essential to understand that each person’s journey is unique. The usual treatment period of Invisalign can vary widely, influenced by several factors affecting Invisalign treatment:

  1. The complexity of the case:
    The complexity of your dental situation is a significant factor in determining the duration of your aligner treatment. For instance, minor problems such as slight crowding or spacing issues may require shorter treatment than more complex cases like severe overbite, underbite, or significant crowding.

  2. Patient’s age:
    Age can also affect the Invisalign process. Younger patients, particularly teenagers, may experience quicker treatment due to their still-growing jaws and teeth. On the other hand, adults may require a longer treatment duration as their teeth and jaws are fully developed and may take more time to adjust.

  3. Consistency in wearing Aligners:
    Invisalign aligners must be worn for about 20-22 hours daily for optimal results. If patients do not adhere to this guideline, it could prolong the treatment duration.

  4. Orthodontic check-ups:
    Regular check-ups with your dental clinic are crucial during your Invisalign treatment. These visits allow your dental professional to monitor your progress and make necessary adjustments to your comprehensive treatment plan so that you stay on track towards achieving your desired results.


Understanding this variety of factors affecting Invisalign treatment can help manage your expectations and prepare you for your Invisalign journey. Remember, every smile is unique, and so is every Invisalign treatment.

Invisalign Treatment Timeline: What to Expect

Understanding the Invisalign treatment timeline can help manage your expectations for a smoother process. Here’s a step-by-step guide on what you can anticipate during your Invisalign journey:

  1. Initial Consultation:
    This is the first step, where you meet with your dentist to discuss your dental concerns and goals. Your dentist will evaluate the situation teeth and decide whether Invisalign is the most suitable course for you.

  2. Treatment Plan Development:
    If you’re a suitable candidate for Invisalign, your dentist will create a customised treatment plan, which involves taking digital scans of your teeth to create 3D models. These models are used to map out the precise movement of teeth.

  3. Receiving Your Aligners:
    Your custom plastic trays will be produced once your treatment plan is ready. You’ll be instructed to wear each set of aligners for about two weeks of treatment before moving on to the next set.

  4. Regular Check-ups:
    You’ll have regular appointments with your dentist throughout your treatment. These check-ups, typically every six to eight weeks, permit your dentist to monitor your development and make any essential corrections.

  5. Completion of Treatment:
    After you’ve gone through all your aligners, your treatment is complete! However, to maintain your new smile, you’ll probably need to wear retainers to keep your teeth from sliding back into their original places.


Remember, the timeline for Invisalign treatment can vary based on specific factors affecting Invisalign treatment, such as the complexity of your case and your compliance with wearing the aligners.

How to Speed Up Your Invisalign Treatment

If you’re undergoing Invisalign treatment, you might wonder if there’s a way to speed up the process. While the average treatment duration is typically between 12 to 18 months, you can take steps to reduce this time potentially. Here are some tips to help you get those straighter teeth sooner:

  1. Wear Your Aligners Consistently:
    This might seem obvious, but it’s crucial. The aligners must be worn for 20-22 hours daily to be effective. The more consistently you wear them, the quicker you’ll see results.

  2. Maintaining Good Oral Hygiene:
    Keeping teeth clean is essential during Invisalign treatment. Brush your teeth before inserting your aligners to prevent bacteria buildup from leftover food particles, which can slow down the treatment process.

  3. Take Care of Your Aligners:
    Clean your aligners regularly to keep them in good condition. Damaged aligners can affect the effects of treatment and can contribute to damage to teeth.

  4. Keep Your Dental Appointments:
    Regular check-ups with your dentist are crucial. These appointments allow your dentist to monitor your progress and make any necessary adjustments to your treatment plan.

  5. Consider Acceleration Devices:
    Devices such as AcceleDent use micro-pulses to stimulate the movement of teeth, potentially speeding up the treatment process. However, discussing this option with your dentist is important to determine if it’s right for you.


Remember, while wanting quick results is natural, it’s important to follow your dentist’s instructions and not rush the process. Invisalign treatment is a journey; every patient’s timeline will differ based on their needs and circumstances.

Invisalign vs Traditional Braces: A Comparison of Treatment Duration

The most commonly considered options for orthodontic treatment are Invisalign and traditional braces. Both have unique advantages and disadvantages; one of the key factors patients often consider is the treatment duration. So, how do Invisalign vs traditional braces stack up against each other regarding speed?

Traditional braces, the time-tested orthodontic treatment method, involve using wires and metal brackets to move your teeth gradually into the proper position. The treatment with metal braces can vary significantly depending on the complexity of the patient’s case, but on average, patients can expect to wear braces for about 18 to 24 months.

On the other hand, Invisalign, a more modern treatment, uses a series of plastic, clear, custom-made aligners to move teeth gradually. The aligners are virtually invisible and can be removed for eating and cleaning, which many patients find more convenient. The average treatment duration for Invisalign is typically shorter, ranging from 12 to 18 months. However, it’s important to note that this can also vary depending on the patient’s case.

Here are some key factors to consider when comparing the treatment duration of Invisalign vs traditional braces:

  1. The complexity of the Case:
    More complex cases with severe misalignment or crowding may require a longer treatment duration, regardless of whether you choose Invisalign or traditional braces.

  2. Patient Compliance:
    With Invisalign, the success and speed of the treatment largely depend on the patient wearing the aligners for the recommended hours per day. Failure to do so can extend the treatment duration.

  3. Age of the Patient:
    The age of the patient may significantly impact the duration of orthodontic treatment. Generally, younger patients may experience quicker treatment times due to the malleability of their jawbones and teeth. In contrast, adult patients might require a longer duration of treatment.

  4. Assessment per patient:
    Every patient’s teeth move at a different rate. Personalised treatment duration estimates can vary even among patients with similar cases.


While Invisalign can often offer a faster treatment duration than traditional braces, the timeline will depend on various factors. It’s important to consult your dentist thoroughly to understand which treatment option suits your needs and lifestyle.
