How Long does Invisalign Take to Work

Embarking on the journey to a more confident smile often leads many to consider Invisalign, the revolutionary orthodontic treatment known for its discretion and efficiency.

As an orthodontist with years of experience transforming smiles, I’ve witnessed firsthand the transformative power of Invisalign.

This cutting-edge solution offers an appealing alternative to traditional braces, promising a less invasive, virtually invisible path to straightening teeth.

But a common question that emerges among patients is: “How long does Invisalign take to work?”

In this article, we’ll delve into the intricacies of Invisalign treatment, offering a comprehensive overview of what patients can expect in terms of treatment duration.

How Long Does Invisalign Take

On average, Invisalign treatment spans 12 to 18 months, though patients may start to see noticeable improvements in their teeth alignment within just a few weeks. This timeline can vary significantly based on the complexity of the case.

Minor adjustments might require a shorter duration, possibly as brief as 6 months, while more complex dental issues could extend the treatment beyond 18 months.

What Are the Factors Affecting the Duration of the Invisalign Treatment?

The duration of Invisalign treatment varies significantly from one patient to another, influenced by many factors.

Understanding these factors can help set realistic expectations for individuals considering or currently undergoing Invisalign treatment.

Here’s a closer look at the main elements that affect how long you might need to wear your Invisalign aligners:

Complexity of Dental Issues

The specific orthodontic issues being addressed play a significant role in determining the length of Invisalign treatment.

Simple cases, such as minor crowding or spacing issues, can often be resolved more quickly, sometimes in as little as six months. In contrast, more complex cases, including severe crowding, gaps, bite discrepancies (such as overbite, underbite, crossbite, and open bite), and rotated teeth, typically require a longer treatment duration.

The more your teeth need to move, the more sets of aligners you will need, extending the treatment time.

Patient Compliance

Invisalign’s effectiveness heavily relies on the patient’s commitment to wearing the aligners as prescribed. For optimal results, aligners should be worn for 20 to 22 hours per day, only being removed for eating, drinking anything other than water, and for oral hygiene routines.

Failure to wear the aligners for the recommended duration can significantly prolong treatment time and may even compromise the final results.

Age of the Patient

Age can influence the duration of Invisalign treatment, primarily due to the differences in bone density and growth potential.

Younger patients, particularly teenagers, may experience faster results due to their still-developing jawbones and teeth, which can adapt more quickly to orthodontic treatment.

Adults, with their denser bone structure, might find that their treatment takes a bit longer, although Invisalign is highly effective for adults of all ages.

Initial Alignment and Spacing

The starting position of your teeth and the degree of alignment or spacing issues can impact how long your Invisalign treatment will take. More significant initial misalignments or spacing problems generally require more time to correct.

Oral Health

Overall oral health can also affect the duration of Invisalign treatment. Issues such as gum disease or cavities need to be addressed before starting or during the treatment, which can extend the overall duration.

Maintaining good oral hygiene and addressing any oral health issues promptly can help keep your treatment on track.

Treatment Plan Adherence

Following the treatment plan as closely as possible, including attending regular check-ups with your orthodontist and transitioning to new aligners on schedule, is crucial for staying within the expected treatment timeframe. Delays in moving to the next set of aligners or missing orthodontic appointments can extend the treatment duration.

Use of Auxiliary Techniques

Some orthodontists may recommend using auxiliary techniques or devices, such as AcceleDent or Propel, which are designed to accelerate tooth movement by stimulating bone remodeling. Such techniques can sometimes reduce the overall treatment time.

In summary, the duration of Invisalign treatment is influenced by a combination of biological, behavioral, and technical factors. By understanding these factors and working closely with their orthodontist, patients can help ensure their treatment is as efficient and effective as possible.

Types of Invisalign Treatment Plans

Invisalign offers a variety of treatment plans tailored to meet the diverse needs and complexities of individual patients’ orthodontic conditions.

Each plan is designed to address specific issues, from minor tooth movements to more comprehensive orthodontic corrections.

Here are the main types of Invisalign treatment plans available:

Invisalign Full

Invisalign Full is the standard and most comprehensive treatment option, designed for adults and teenagers with moderate to complex orthodontic issues. It can address a wide range of concerns, including crowding, spacing, crossbite, overbite, and underbite.

There is no set limit to the number of aligners in this plan, making it suitable for achieving significant orthodontic corrections. The treatment duration varies depending on the individual’s needs but typically ranges from 12 to 18 months.

Invisalign Teen

Specifically designed for teenagers, Invisalign Teen accounts for the unique challenges and needs of adolescent patients, including growth and development concerns.

This plan includes a few special features, such as compliance indicators (color indicators to help gauge wear time), eruption tabs to accommodate growing teeth, and replacement aligners, acknowledging that teens might be more likely to lose or damage their aligners. It offers the same range of treatment capabilities as Invisalign Full but is tailored to the teenage lifestyle and orthodontic needs.

Invisalign Lite

Invisalign Lite is intended for less complex cases, offering a shorter treatment duration, typically around 6 to 7 months. It’s ideal for patients with minor crowding or spacing issues and those who require only slight corrections to their smile.

The plan generally includes a maximum of 14 aligners and is an excellent option for individuals looking for a quick and effective solution to minor orthodontic concerns.

Invisalign Express

Invisalign Express is designed for very minor corrections and is the quickest Invisalign treatment available. There are two types of Express treatments: Invisalign Express 5 and Invisalign Express 10, indicating the maximum number of aligners used.

These plans are suitable for patients with minimal orthodontic needs, such as small gaps between teeth or very slight crowding. Treatment duration can be as short as 3 to 6 months, making it an attractive option for individuals preparing for special events like weddings.

Invisalign Go

Invisalign Go is a relatively new addition tailored for general dentists to address minor to moderate orthodontic issues, focusing on the aesthetic improvement of the front teeth. It provides a simplified treatment process for cases that do not require the comprehensive corrections of Invisalign Full, making it a convenient option for patients looking to enhance their smile without extensive orthodontic intervention.

How to shorten the Invisalign treatment period

Shortening the Invisalign treatment period can make straightening teeth more appealing and manageable for many patients. While the total duration of Invisalign treatment varies based on individual orthodontic needs, there are strategies both patients and orthodontists can employ to potentially reduce the length of treatment.

Here are several tips for those looking to achieve their desired results more quickly:

Adhere Strictly to Wear Time Recommendations

The most critical factor in the success and speed of Invisalign treatment is wearing the aligners for the recommended 20 to 22 hours per day. Removing aligners only for eating, drinking anything other than water, and oral hygiene practices ensures that treatment progresses as planned.

Attend Regular Check-ups

Keep up with your scheduled orthodontic appointments. These visits allow your orthodontist to monitor your progress, make necessary adjustments to your treatment plan, and provide you with your next sets of aligners without delay.

Use Invisalign Cleaning Systems

Keeping aligners clean and free from bacteria can prevent unnecessary complications that might delay treatment. Use Invisalign cleaning crystals or similar products to maintain your aligners, ensuring they remain clear and fit well throughout the treatment.

Practice Good Oral Hygiene

Maintaining excellent oral hygiene helps prevent gum disease and cavities, which can disrupt the treatment process. Brush and floss after every meal before putting your aligners back in to keep your teeth and gums healthy.

Use Additional Orthodontic Devices if Recommended

Your orthodontist may recommend using adjunctive devices like AcceleDent or Propel, which are designed to accelerate tooth movement. These devices use gentle vibrations or micro-osteoperforations to stimulate bone remodeling, potentially reducing treatment time.

Follow Dietary Guidelines

Avoid foods and beverages that can stain or damage your aligners. Damaged aligners may not exert the correct amount of pressure on your teeth, potentially prolonging treatment.

Immediately Address Fit Issues

If you notice that your aligners are not fitting well or if you experience any discomfort beyond the initial adjustment period, contact your orthodontist immediately. Ill-fitting aligners can hinder progress and extend the treatment duration.

Avoid Unnecessary Breaks

Minimize or eliminate breaks in wearing your aligners. Continuous wear without significant interruptions is crucial for maintaining the momentum of tooth movement.

Be Consistent with Changing Aligners

Change your aligners according to the schedule provided by your orthodontist. Delaying the switch to new aligners can slow down the treatment process.

Can plastic really move your teeth?

Yes, plastic can indeed move your teeth, a principle that underpins the technology behind clear aligners like Invisalign. This might seem surprising given that plastic is often associated with flexibility and not the force necessary for orthodontic treatment.

However, the specific type of medical-grade, high-quality thermoplastic material used in the manufacture of these aligners is engineered to exert controlled force on the teeth to move them gradually into the desired position.

How It Works

The process begins with a digital scan of your teeth, from which a precise 3D model is created. This model is used to plan the movement of your teeth into their optimal positions.

Based on this plan, a series of custom-made aligners are produced. Each aligner in the series is slightly different, designed to move your teeth incrementally. When you wear an aligner, it applies controlled force to specific teeth that need to be moved.

The Science Behind the Movement

The plastic aligners work by exerting pressure on the teeth in specific directions. This pressure activates the cells in your jawbone to begin a process known as bone remodeling.

When pressure is applied to a tooth, the bone in the path of the moving tooth starts to dissolve, allowing the tooth to move, while new bone grows behind the tooth to support its new position.

This is a gradual process, with each aligner moving the teeth a small amount until the desired alignment is achieved.

Controlled Force for Safety and Efficiency

The force applied by clear aligners is carefully controlled and targeted. Unlike traditional braces, which can apply a broader force, clear aligners can move teeth in a more precise manner.

This targeted approach not only makes the treatment efficient but also minimizes discomfort for the patient.

Material Matters

Not all plastics are created equal, especially when it comes to medical and dental applications.

The plastic used in Invisalign and similar aligner systems is a result of extensive research and development. It must be durable enough to exert the necessary force over a couple of weeks, flexible enough to be comfortable, and safe for long-term use inside the mouth.

In summary, while it might seem unlikely at first, specialized plastics have been proven highly effective in orthodontics for moving teeth. This technology has revolutionized the field, offering a less visible, more comfortable alternative to traditional metal braces. The effectiveness of clear aligners is well-documented, and millions of people have successfully improved their smiles thanks to this innovative use of plastic.

What’s the fastest brace system out there

The fastest brace system varies by individual needs, but generally, self-ligating braces are known for being quicker due to reduced friction between wires and brackets. For specific cases, short-term orthodontic solutions like Six Month Smiles can offer rapid results, primarily focusing on cosmetic corrections of the front teeth.
