Metal braces have long been the treatment of choice for crooked teeth but Invisalign® presents an alternative to brackets and wires.

The aligner trays are comfortable, convenient, and virtually undetectable when they are in place. It's a clear orthodontics option.

Learn how Han & Ahn DMD can expertly straighten adults' and teens' teeth at our office in McLean, VA.

All About Invisalign How Does It Work?

Traditional braces use brackets, wires, and bands to alter the position of a patient's teeth. Invisalign relies on clear plastic aligners. These clear plastic aligners are worn like a retainer or mouth guard, fitting right over the teeth. Over time, the aligners straighten a patient's smile, applying controlled pressure much like braces.

Treatment usually takes 12–18 months, and you'll switch to a new set of aligners within your custom series every two weeks or so.

In addition to aligners, Invisalign treatment may also use attachments. These attachments are tooth-colored bumps that are applied to the teeth. The attachments serve as anchors for the aligners and work a lot like the brackets used in orthodontic treatment with braces. The attachments help shift teeth into a better position.

The Benefits of Invisalign

Clear Aligners Are Nearly Indetectable

The aligners are virtually invisible when you're wearing them. Most people will not even notice you are undergoing Invisalign treatment. You can also take out the aligners for photos and special occasions.

The Aligners Are Comfortable

The clear aligners are made of smooth, BPA-free plastic. The aligners will not irritate your cheeks and gums, which is a common complaint about braces. No brackets or wires are required.

Easy to Remove and Clean

Unlike traditional braces, aligners are easy to clean. No time-consuming hygiene routines are required. You can remove aligners when brushing and flossing, and clean the aligners with ease.

Eat Your Favorite Foods

Braces impose limitations on your diet, but that's not the case with Invisalign. Because you can remove the aligners to eat, your diet will not be restricted in any way during the course of your treatment.

Invisalign Is Best

For Mild to Moderate Cases

These removable clear aligners are intended to correct mild to moderate alignment concerns. This means that some people with especially complex malocclusion don't qualify for treatment, even with aligner attachments. If this turns out to be the case for you, don't worry—our McLean, VA, team can still straighten your smile. Dr. Ahn is a skilled orthodontic specialist who regularly helps patients with all types of needs see great results from their treatment.

How Long Does Invisalign Take?


The length of treatment varies from patient to patient based on the severity of their malocclusion. It can take as little as six months, or between 12 to 18 months. During your visit to our McLean practice, Dr. Ahn can provide an estimated treatment time using individualized computer models.

Invisalign Treatment Is Easy

Our dental office in McLean, VA, is fully modernized and designed for your comfort. You can enjoy amenities like aromatherapy and paraffin wax hand treatments during your Invisalign checkups.

Custom Treatment Plan

Using digital X-rays, pictures, and impressions, Dr. Ahn will map out a precise treatment plan, including the exact movements of your teeth. Patients will be shown a virtual representation of how the teeth will move during treatment.

Wearing the Clear Aligners

Patients wear their clear aligners for 20 to 22 hours per day, removing them to eat, drink beverages other than cold water, and to brush and floss. Every two weeks, the previous aligner is discarded and the next aligner tray is worn.

Periodic Checkups

To monitor your progress, you will have occasional checkups with Dr. Ahn. These are once or twice each month until the process is completed. You can also contact our practice between checkups if you have any questions or concerns.

It's Important to Wear Your Retainer Once Treatment Is Complete

After your teeth have reached their proper positions and Invisalign treatment ends, Dr. Ahn will provide a custom retainer for you to wear. Your teeth will still want to shift back to their natural positions for several months, so it's incredibly important you wear the retainer as directed to not risk your results.

Dr. Ahn may recommend wearing the retainer just as you wore your removable aligners, or she may recommend that you wear it only at night. It will be entirely dependent on your specific case.

If you do miss a day with your retainer, though, don't worry. It takes some time for teeth to shift back, and you won't undo your results overnight. Just focus on being consistent, and you can enjoy your beautiful smile for years to come.

Our iTero Scanner Makes Impressions Easier Than Ever Before

No one wants to deal with messy dental putty when it's time to take impressions. At Han & Ahn DMD, you don't have to.

Our dentists use the iTero® intraoral scanner to capture digital impressions of your teeth, gums, and oral structures. This handheld camera can take thousands of hyper-accurate images in a matter of moments, which reduces time and increases comfort in the dentist's chair.

These scans will be instantly uploaded to our computer systems, where Dr. Ahn can review 3D models of your teeth and get to work on a more precise treatment plan than would otherwise be possible.

Propel Orthodontic Technology Accelerating Invisalign Treatment

A recently developed orthodontic therapy called Propel® may be added on to your Invisalign treatment to deliver enhanced results in less time than ever before. Propel often cuts the overall treatment time in half.

This Propel method involves the creation of micro-osteoperforations, small pinholes around the bone tissue surrounding the teeth. These tiny holes make the bone on either side of a tooth more pliable, and hence responsive to the pressure exerted by the aligners. In addition, the process stimulates bone regrowth, increases blood flow, and restores jaw tissue quickly.

Dr. Ahn ensures this process is as comfortable as possible. During your consultation, she'll let you know if Propel is a good option for you.

Does Insurance Cover Invisalign?

Some dental insurance providers will cover Invisalign just like they cover braces, but not all. Our McLean team can help you verify your coverage ahead of time. We accept all PPO insurance plans and will work to get your coverage maximized.

Han & Ahn DMD also accepts CareCredit® financing so patients don't have to deal with high out-of-pocket expenses, regardless of insurance status.

Want to work out a payment plan with us directly? Let's talk about our in-house financing options. We offer 0% interest for patients who put 50% down at the start of treatment.

Invisalign Works For All Types of Patients

Invisalign for Adults

Many adult patients who want straighter teeth without the "braces phase" choose Invisalign. Rather than getting adult braces, patients wear their clear aligners throughout the day. Invisalign treatment means orthodontic care that doesn't affect your professional obligations, your social life, or most daily activities.

Invisalign for Teens

Many teenagers need orthodontic treatment but don't want metal braces. Invisalign can be a great choice for teenage patients who are dedicated to wearing their aligners as instructed to see the best results. If a teenage patient accidentally loses a set of aligners, our orthodontist can help them with replacements.

Invisalign Express

For people who experience minor issues with spacing, crowding, and misalignment, Invisalign Express is a great option. This form of treatment uses the same principles as traditional Invisalign. Only 10 clear aligners are required, and sometimes fewer. Final results are achieved in as little as six months.

Dr. Ahn is just amazing! I strongly recommend her to anyone who needs braces. She is not just knowledgeable and experienced, she is very flexible, kind and patient with my teenager boy who went thru a very hard time emotionally during COVID. He just got his braces removed yesterday and it's just perfect and my son was very happy with the result. She and the staff are just wonderful and I cannot say enough about them.
