What is Invisalign®?

Invisalign® is an orthodontic solution that uses a series of nearly invisible, custom-made trays to gradually move your teeth into their ideal positions. These aligners are designed for comfort and discretion, making them a great option for teens and adults who want to improve their smile without the look or feel of traditional braces. At One Smile Orthodontics, we use Invisalign® to treat a range of issues, from minor crowding to more complex bite problems. Many patients choose Invisalign® clear aligners because they’re removable, allowing you to eat what you want and brush and floss with ease. Treatment times can vary depending on your case, but most people begin to notice changes within a few months. If you're looking for a flexible, modern way to enhance your smile, Invisalign® might be the right fit for you.

The Invisalign® process

Book Now
1

Your complimentary consultation

Every journey starts with a free consultation. We’ll take high-quality images, evaluate your bite, and talk about your goals. Dr. Kim will help you visualize what your smile can look like and determine if clear aligners are the right fit for you.

2

Digital scan & custom plan

No goopy impressions here. We use advanced digital scanning to create a precise 3D model of your teeth. From there, we build a treatment plan that maps out every movement so you’ll know exactly what to expect.

3

Your aligners arrive

Once your aligners are ready, we’ll show you how to wear them, when to switch to the next set, and how to care for them. Most patients wear their aligners 20–22 hours a day for best results.

4

Progress and smile reveal

We’ll see you every few weeks to check your progress and keep your treatment on track. As your smile transforms, you’ll feel more confident with every visit. When treatment ends, we’ll provide a retainer to help maintain your results.

Frequently asked questions

Find answers to common questions from our clients.

Treatment time varies depending on the complexity of your case. For mild cases, it can be as short as six months. On average, most patients complete treatment in 12–18 months. During your consultation, Dr. Kim will give you a realistic timeline based on your goals.

Invisalign® is generally more comfortable than traditional braces. You might feel some pressure or tightness when starting a new set, which means the aligners are working. This feeling typically fades within a day or two.

Many patients with crowding, spacing, mild bite issues, or rotated teeth are great candidates for Invisalign®. If your case is more complex, Dr. Kim can walk you through your options, including hybrid or combination approaches that still keep aesthetics in mind.

Real smiles.
Real stories.

If you are an adult patient who is considering a ortho treatment that you've been thinking about for your entire life, I highly recommend Dr. Kim. I was initially nervous about the process but Dr.Kim was very attentive and took time to come up with the plan that will address my concerns so I decided to start the treatment. My two main concerns were crowded lower anterior teeth and narrow upper jaw. Before starting the treatment, Dr. Kim clearly explained the treatment plan and timeline, which helped alleviate my concerns. Since I didn't want to wear the palate expander, Dr. Kim came up with alternative solution that can be done with Invisalign. Even as a first time ortho patient, I felt treatment plan was well thought out and precisely moving my teeth without causing excessive pain. I'm currently done with my initial treatment and waiting for refinements sets but I'm already very happy with the results so far. One Smile Orthodontics truly lives up to its name.

I don't normally leave reviews, but after visiting Dr. Namgu Kim I feel compelled to share it.

I went for a consultation about possibly getting braces or Invisalign, and as someone who always had a lot of anxiety around dental visits, I was honestly nervous walking in. But the moment I met Dr. Kim, I felt at ease. He has a reassuring presence and a genuine way of listening that makes you feel cared for as a patient -- not rushed, not pressured, just understood.

Dr. Kim took the time to thoroughly examine my teeth, explain what he was seeing, and walk me through my options in a way that was clear and easy to understand. He pointed out details that other dentists had overlooked and laid out a step-by-step plan that made me feel confident about what comes next. He focused on what would genuinely serve my needs and comfort level. As someone with dental anxiety, that meant a lot. For the first time, I felt like I was in the hands of a specialist who really prioritized my well-being.

If you're considering orthodontic treatment -- Invisalign, braces, or even just a professional opinion -- I cannot recommend Dr. Namgu Kim highly enough. His expertise is exceptional, his communication is clear, and his compassion is unmatched. I walked out feeling informed, supported, and surprisingly excited about the next steps. Thank you!
