Invisalign & Clear Aligners in Fountain Valley, CA

Straightening your teeth with clear aligners, often referred to as Invisalign, is about more than improving your smile. It supports your long-term dental health, your bite, and your overall comfort.

What is Invisalign?

Invisalign is a popular brand for clear aligners, but it is not your only option for invisible braces.

Most people searching for “Invisalign” are actually searching for clear aligners, the removable, nearly invisible trays that gradually move teeth into alignment. Invisalign is one brand that offers this type of treatment. But it is not the only option, and it may not always be the best one for your case.

At Kieu Orthodontics, we have rigorously tested many different clear aligners systems, including Invisalign. But after years of working with patients from Fountain Valley, Huntington Beach and throughout Orange County, our team recommends Angel Aligners for most cases. We will explain why below, and we are always happy to discuss which option makes the most sense for you at your consultation.

How does Invisalign & other clear aligner treatment work?

Clear aligners are custom-made trays worn over your teeth for about 20 to 22 hours per day. Each set of trays applies gentle pressure to gradually shift your teeth toward their ideal position. You move to a new set of trays every one to two weeks, depending on your treatment plan.

There are no brackets or wires. You take the trays out to eat, brush, and floss. Most people around you will not notice you are wearing them at all.

Clear aligners can be used to treat:

  • Crowded or overlapping teeth
  • Gaps between teeth
  • Overbites and underbites
  • Crossbites and open bites
  • General misalignment


The right system for your case depends on your teeth, your bite, and your treatment goals.

What are your options for clear aligners?

Clear aligners come in several brands and systems, each with different materials, technology, and treatment approaches. At Kieu Orthodontics, we recommend Angel Aligners. We have extensive training with Invisalign, and we’re happy to recommend Invisalign if it’s the right fit for you.

Our Reccommendation

Angel Aligners

Angel Aligners are what we recommend for most of our patients. They use newer materials, built-in attachment technology, and a dual-aligner system designed for more comfort and less time in the chair.

Why do we recommend Angel Aligners?

1

Less Visible

The clearest material we tested, giving you the most esthetic and discreet option possible.

2

More Comfort

Smoother edges reduce irritation, making them more comfortable to wear all day.

3

Better Quality

Stronger stain-resistant material so your aligners look fresh and clear throughout your treatment.

Are you a good fit for clear aligners?

Clear aligners are a great option for many patients, especially those looking for a comfortable, discreet alternative to traditional braces.

Kids

In early treatment, clear aligners are designed to gently guide teeth. They work well with kids if they are responsible enough to wear them consistently.

Teens

Teen treatment prioritizes supporting developing smiles, improving alignment, and creating a healthy bite as they finish growing.

Adults

Adult treatment prioritizes precise tooth movement, balanced alignment, and long-term smile stability.

Frequently Asked Questions

Invisalign treatment typically costs between $3,000 and $8,000, depending on the complexity of your case, how long treatment takes, and whether additional orthodontic care is needed. Some minor cases may cost less, while more involved cases can be higher. Dental insurance may cover part of the cost, and some plans offer orthodontic benefits that apply to Invisalign or clear aligners. In most cases, insurance helps reduce the total cost rather than covering the full amount, but our team can verify your benefits and provide a clear estimate before treatment begins.
Yes, Invisalign and other clear aligners may be able to correct some overbites, depending on the severity of the bite and the type of tooth movement needed. During your consultation, our orthodontists evaluate your teeth, bite, and jaw relationship to determine whether clear aligners are the right option or whether another orthodontic approach would provide a better result. The American Association of Orthodontists notes that aligners can treat overbite in some cases, but aligners are not right for everyone and an orthodontist should recommend the best option based on the patient’s needs.
Treatment time varies depending on the complexity of your case and how consistently you wear your aligners. On average, many patients complete their treatment within several months to over a year. During your consultation, we provide a more accurate timeline based on your individual treatment plan and expected tooth movement.
Yes, clear aligners are designed to accommodate a wide range of patients, including teens and adults. We evaluate factors such as dental development, alignment concerns, and lifestyle to determine if this option is the right fit. With proper wear and compliance, patients of different ages can achieve effective and predictable results.
