A Different Level of Care
Honest Recommendations
We only recommend treatment when we believe it will make a meaningful difference. You'll always leave with an honest assessment and a clear plan, never pressured and never oversold. Many of our patients visit us after seeking a second opinion elsewhere.
Orthodontists Who Teach Orthodontists
Dr. Lee and Dr. Pi bring a rare depth of expertise to every patient. Together they teach clear aligner treatment to residents at UCSF and InSmile lingual braces to orthodontists nationwide. Dr. Lee co-invented InSmile Braces and serves as InSmile's Chief Medical Officer.
Treatment Tailored to Your Life
We offer braces, clear aligners, and InSmile hidden braces for all ages, and we'll help you choose the option that genuinely fits your goals, your lifestyle, and your budget. The right treatment is the one that works for your life, not ours.
Your Smile. Guaranteed. For Life.
Most practices end their relationship with you the day your braces come off. Ours doesn't. Our Smile for Life Guarantee means lost retainers and minor shifting are covered for a minimal copay. Your forever smile is our commitment, not just our goal.
OUR SERVICES
Find the Right Treatment for your Smile
InSmile Braces
InSmile Braces are the most discreet way of straightening your teeth. These lingual braces are placed behind the teeth, so no one can tell that you have braces on. Our doctors co-invented this technology and even wrote the textbook on it, so there’s no better office than Life Orthodontics to be treated with InSmile Braces.
Clear Aligners
Clear aligners, such as Invisalign, are an excellent esthetic option to straighten your teeth without the need for braces. Our doctors are masters of this option and can treat almost any case with clear aligners. With their expertise, they even teach orthodontic residents how to use clear aligners as assistant professors at UCSF.

Braces
Braces are a proven and reliable option for straightening your teeth. While most offices use generic one-size-fits-all braces, we are one of the few offices who use custom braces that are personalized to fit your teeth and use digital treatment planning software which yields faster treatment with fewer appointments.
Phase I
Phase I treatment addresses orthodontic issues in younger children, typically between ages 7 and 10, before all permanent teeth arrive. Early intervention guides jaw development, creates space for incoming teeth, and can prevent more complex and costly treatment down the road. We recommend an evaluation by age 7.

CARING FOR YOU LIKE FAMILY
Your Ortho Home

Our Promise to You
Smile for Life guarantee
After treatment, it is an all-too-common reality for patients to lose or break their retainers or experience minor relapse due to inconsistent retainer use. Typically, you would have to pay a significant amount for a new retainer or retreatment, but at Life Orthodontics, we have you covered. Because we are committed to treating you like our own family members and we are proud of the smiles we create, we want to ensure the smile you love lasts a lifetime. That is why we provide our patients with an exclusive Smile for Life Guarantee which includes Retainer and Life Smile Insurance. Your smile is our priority, and as your Ortho Home, we are here to help you maintain it for life!
Retainer Insurance
If you lose or break your retainer, don’t worry! For a small copay, we will replace your retainer so you can keep your forever smile intact.
Life smile insurance
If your teeth ever shift on you, don’t worry! For a minimal copay, we will retreat you and have your forever smile restored.

Don't Take Our Word for It
Choosing an orthodontist is a decision that shouldn't be taken lightly. After thorough research, we decided on Dr. Lee and Dr. Pi for my son's orthodontic treatment.
Upon visiting their practice for a consultation, we were immediately impressed by the warm and welcoming team at Life Orthodontics.
During the consultation, they took the time to listen to our concerns and answered our questions with patience and clarity. Their comprehensive evaluation and personalized treatment plan options instilled confidence in their ability to address our orthodontic needs effectively.
Our experience with them has exceeded all expectations, and we wholeheartedly recommend them to all our friends seeking top-quality orthodontic care.

I just wanted to share my recent experience at Life Orthodontics because it was honestly fantastic. Right from the first chat with Dr. Pi, I felt like I was in good hands. Super patient, answered all my questions (even the silly ones), and you could tell she genuinely cared about my journey to a straighter smile.
The whole team over there is a delight. I never thought I'd say this about going to the dentist, but it's genuinely a friendly place. They've got this cool vibe that just puts you at ease.
