Orange County Invisalign

For those who want to straighten their teeth but don’t like the look or feel of traditional braces, Invisalign is an excellent option. Invisalign aligners are clear, removable, and virtually invisible, making them the go-to choice for those who want to improve their smile discreetly.

At Treehouse Orthodontics, we specialize in using Invisalign to help our patients achieve the smile they've always wanted, with minimal disruption to their daily lives. Whether you're attending school, starting your first job, or heading out with friends or family, Invisalign straightens your teeth in a more secreted manner then traditional braces. The beauty of Invisalign is in its flexibility. You can remove the aligners when you eat, brush your teeth, or have a special event, meaning you are in control! So don’t sweat it; you can continue to enjoy your favorite foods and maintain excellent oral hygiene throughout your treatment. And because Invisalign is custom-made for your teeth, the aligners fit snug and comfortable, making the process virtually pain-free.

Invisalign For Children

For children, Invisalign offers a gentle and effective way to guide growing teeth into the right position. The Invisalign Palatal Expander(IPE) is a popular option when accomplishing expansion in children. The IPE provides the skeletal expansion in children needed when adult teeth are still growing, but with the benefits of being a removable appliance. Our approach ensures that the treatment is not only effective but also aligned with the child’s development, providing results that last a lifetime.

Invisalign For Teenagers

Teenagers love Invisalign because it fits seamlessly into their busy lives. Whether it's school, sports, or hanging out with friends,Invisalign allows teens to straighten their teeth without the hassle and appearance of metal braces. At Treehouse Orthodontics, we work closely with teens to ensure they are comfortable with their treatment plan and excited about the results.

Invisalign For Adults

For adults, Invisalign is often the preferred choice because it provides a subtle way to achieve a perfect smile. Whether you're preparing for a career milestone or big life event, or simply want to boost your day-to-day confidence, how you feel is important to us. We customize each treatment plan to fit your lifestyle, ensuring that your journey to a better smile is convenient and even enjoyable. Invisalign for adults is a great option as a tune-up to fix minor tooth movement over time.

Phase 1 - Children

In this patient's Phase One transitional treatment at 8 years old, the primary goal was to create sufficient space by using a customized expander appliance to expand the jaw for proper growth. This growth facilitated in the alignment of the upper front teeth to ensure proper spacing for the upper cuspids to erupt into correct alignment.

Orange County Braces

Orange County, CA Braces

Braces have been the gold standard in orthodontic treatment for decades, and for good reason—they're effective in addressing even the most severe orthodontic issues. At Treehouse Orthodontics in Orange County, we offer traditional braces as a reliable solution for patients who need significant tooth movement or have complex cases: Braces allow our orthodontists to have greater control over the alignment of your teeth, ensuring you experience the best possible outcome.

But what many don’t realize, is that there are different types of metal braces; and if you’re considering traditional braces for yourself or your child, wouldn’t you want to choose the gentlest, most effective approach? That’s why we provide a variety of advanced methods for skeletal expansion and aligning teeth, all designed to maximize both appearance and function.For many patients, metal braces are the most cost-effective option. What’s more, they don't require the same level of compliance asInvisalign. This makes them particularly well-suited for younger patients who might struggle with the discipline needed to wear aligners consistently. With braces, you can rest assured that your treatment is always on track, leading to a beautiful, healthy smile.

Orange County Retainers

Orange County, CA Retainers

Retainers play a crucial role in maintaining the results of your orthodontic treatment. After investing time, money and energy into straightening your teeth, it's essential to protect your new smile from shifting back to its original position. At Treehouse Orthodontics, we offer a variety of retainers that are designed to keep your teeth in place and safeguard your investment.

Retainers help stabilize your bite, ensuring that your teeth feel comfortable in their new position long after your braces or Invisalign treatment is complete. They also allow your gums and bone structure to adjust to the new alignment, reducing the risk of relapse. Whether you’d benefit from a fixed retainer for added security or a removable retainer for convenience, our team will help you choose the right option for your needs.
