Straighter teeth are not just about aesthetics. They are the foundation of a healthier, longer-lasting smile.

Dr. Nidhi Pai has been ranked in the Top 1% of Invisalign providers in the United States for over 15 consecutive years, making her one of the most experienced clear aligner specialists in the entire Bay Area. She also offers Candid Pro for patients seeking a flexible, cost-effective path to a straighter smile.

Get Started

What is Invisalign?

Invisalign is the world's most widely used clear aligner system: a modern orthodontic treatment that gradually moves your teeth into their ideal positions using a series of custom-made, virtually invisible plastic aligners. Each set of aligners is worn for approximately two weeks before progressing to the next, with the full treatment typically spanning several months to two years, depending on the complexity of the case.

Unlike traditional metal braces, Invisalign aligners are fully removable. You take them out to eat, drink, brush, floss, and put them back in. There are no brackets, no wires, no dietary restrictions, and no adjustments. The process is discreet, comfortable, and remarkably well-suited to the demands of a busy Bay Area lifestyle.

At Smiles by Pai, every Invisalign treatment begins with a digital scan using the iTero intraoral scanner: precise, impression-free 3D imaging that produces a more accurate treatment plan and allows you to preview your projected results before a single aligner is made.

Your Clear Aligners Journey

  • 1. Personalized Consultation

    Your first visit begins with a conversation. Dr. Pai listens to your goals, reviews your dental and medical history, and evaluates your bite, alignment, and overall oral health. She will discuss which system, Invisalign or Candid Pro, is the better fit for your case, and whether any preparatory work is recommended before treatment begins.

  • 2. Digital Scan with iTero

    No messy impressions. Dr. Pai uses the iTero intraoral scanner to capture a precise 3D model of your teeth in minutes. This digital scan is used to create your custom aligner series and generate a digital preview of how your teeth will move throughout treatment and what your final result will look like. You see the projected outcome before a single aligner is made.

  • 3. Custom Aligner Fabrication

    Your aligners are precision-manufactured from your digital scan. A series of clear, custom-fit trays that guide your teeth through small, controlled movements. Each set is worn for approximately two weeks before you advance to the next. Aligners should be worn 20 to 22 hours per day for the most predictable results.

  • 4. Progress Monitoring

    Dr. Pai monitors your progress at regular intervals throughout treatment. For Invisalign patients, this happens through scheduled in-office visits. For Candid Pro patients, monitoring combines in-office check-ins with remote tracking between appointments. If the teeth are not moving as planned, which occasionally happens, Dr. Pai identifies this early and adjusts the treatment plan accordingly. This is the value of an experienced provider.

  • 5. Refinements

    In many cases, a round of refinement aligners is used near the end of treatment to perfect the final result, addressing any minor movements that did not fully respond to the initial series. This is a normal and expected part of the process, and Dr. Pai plans for it from the outset.

  • 6. Protecting Your Result

    Once treatment is complete, retainers are provided to hold your teeth in their new positions. This step is not optional. Teeth have a natural tendency to shift over time, and consistent retainer wear is what makes your result permanent. Dr. Pai provides detailed guidance on retainer wear and maintenance at the completion of every case.

15 Years in the Top 1% of Invisalign Providers Nationwide

Invisalign awards provider rankings based on the volume and complexity of cases completed each year. Reaching the top 1% nationally consistently for over 15 consecutive years reflects a depth of experience that very few providers in the Bay Area can match.

For patients, this matters in ways that are not always obvious. A highly experienced Invisalign provider has encountered and successfully treated thousands of cases across the full spectrum of complexity. They understand the nuances of tooth movement, the limitations of clear aligner therapy, and when to recommend an alternative approach. They catch issues early, refine treatment plans mid-course when needed, and consistently produce results that less experienced providers simply cannot.

Dr. Pai treats Invisalign patients ranging from teenagers to adults in their 80s. She approaches every case with the same attention to detail because straight teeth are not just about appearance. They are a foundation for long-term oral health, a more stable bite, and a smile that ages beautifully.

“My goal is deeper than a beautiful smile. I want to make their oral health strong and sustainable. Because when something is structurally sound and healthy, the beauty naturally follows.”
— Dr. Nidhi Pai, DDS

Offering Candid Pro

Dr. Pai is also a certified Candid Pro provider. Candid Pro is a clear aligner system developed specifically for adult patients with mild to moderate alignment concerns. It combines in-office visits with remote progress monitoring, making it a convenient and more affordable alternative for patients whose cases do not require the full scope of Invisalign treatment.

Unlike direct-to-consumer aligner companies that operate without ongoing clinical oversight, Candid Pro is doctor-led from start to finish. Dr. Pai reviews your case, approves your treatment plan, and monitors your progress throughout. You are never without professional guidance.

Straight Teeth Are About More Than How You Look

Most patients come to Dr. Pai seeking straighter teeth to achieve a more confident smile. That is a completely valid reason, and she will deliver on it. But she also wants her patients to understand what properly aligned teeth do for their long-term health, because that is the fuller picture she is always working toward.

Easier to Clean, Healthier for Life

Crowded or overlapping teeth create hard-to-reach surfaces where plaque and bacteria accumulate — the exact areas a toothbrush and floss struggle to reach. Properly aligned teeth are easier to clean thoroughly at home and at every professional appointment, reducing the lifetime risk of gum disease, decay, and tooth loss.

A More Stable Bite

Misaligned teeth often lead to an uneven bite, with some teeth bearing more pressure than others. Over time, this causes wear, fractures, and stress on the jaw joint. Dr. Pai evaluates every patient's bite as part of the treatment planning process because alignment treatment that corrects the teeth without considering the bite only solves half the problem.

The Foundation for Cosmetic Work

For patients considering veneers or a smile makeover, straightening first is often the right sequence. Veneers placed on properly aligned teeth require less preparation, result in a more natural appearance, and last significantly longer. Dr. Pai frequently recommends Invisalign or Candid Pro as the first step in a broader smile transformation plan, and the results of doing it in the right order are dramatic.

A Smile That Ages Well

Dr. Pai thinks in decades, not appointments. Teeth that are properly aligned and sitting in a balanced bite are far less likely to shift, wear unevenly, or require costly restorative work later in life. This is preventive dentistry in its truest form and the philosophy behind everything she does.

Who is a Good Candidate for Clear Aligners?

Clear aligners work exceptionally well for most adults and teens dealing with a wide range of alignment concerns. You may be an ideal candidate if you have:

  • Crowded or overlapping teeth

  • Gaps or spaces between teeth

  • Mild to moderate overbite, underbite, or crossbite

  • Teeth that have shifted after previous orthodontic treatment

  • An uneven bite that is contributing to wear or discomfort

  • A desire to straighten your teeth before veneers or cosmetic work

There is no upper age limit. Dr. Pai has successfully treated patients well into their 80s with Invisalign because it is never too late to invest in a healthier, more confident smile. One of her most memorable patients was an 85-year-old man who had felt self-conscious about his teeth his entire life. He had simply never had the opportunity to address it. Dr. Pai straightened his teeth and gave him something he had been waiting for for decades.

Very severe bite issues or cases requiring skeletal correction may need a referral to an orthodontic specialist, which Dr. Pai can coordinate. She will always be honest about what clear aligner therapy can and cannot achieve in your specific situation.

Why Patients Choose Clear Aligners Over Traditional Braces

Virtually Invisible

Clear aligners are transparent and close-fitting. Most people will never notice you are wearing them.

Removable

Take them out to eat, drink, brush, and floss. No dietary restrictions. No navigating around brackets and wires.

Comfortable

Smooth plastic with no metal edges, brackets, or wires to cause irritation to the cheeks and gums.

Predictable

Digital planning means your treatment path and projected outcome are mapped before treatment begins. No guesswork.

Fewer Visits

Especially with Candid Pro's hybrid monitoring model, clear aligners require fewer in-office visits than traditional orthodontic treatment.

Better Oral Hygiene

Because aligners are removable, your normal brushing and flossing routine is completely unaffected throughout treatment.

Why Choose Dr. Nidhi Pai for Invisalign in the Bay Area

The Invisalign provider ranking system exists precisely because experience matters. The top 1% designation reflects not just volume, but also the breadth and complexity of cases a provider has seen, the depth of their clinical judgment, and their ability to produce consistently excellent results across a wide range of patients. Dr. Pai has held this ranking for over 15 consecutive years.

A Cosmetic Dentist's Perspective

What sets Dr. Pai apart from a standard Invisalign provider is the cosmetic lens through which she approaches every case. She is not simply moving teeth into a textbook-correct position. She is evaluating how your teeth will look within your face. Your smile line, your lip position, the proportion of tooth visible when you smile, and planning alignment treatment with that aesthetic outcome in mind. When the straightening is done, the smile is already optimized for whatever comes next, whether that is veneers, whitening, or simply enjoying a beautifully natural result.

A Holistic Foundation

Dr. Pai evaluates the bite, the jaw, and the long-term trajectory of every patient's oral health before recommending any treatment. For patients who grind, clench, or have jaw imbalances, alignment treatment is often the most important first step — not just cosmetically, but clinically as well. She treats the cause, not just the symptom.

Invisalign and Candid Pro Under One Roof

Offering both systems allows Dr. Pai to recommend the right tool for each patient's specific situation, rather than fitting every case into a single solution. This flexibility and the clinical experience to know when each system is appropriate is something most Bay Area providers simply do not offer.

Frequently Asked Questions About Invisalign and Candid Pro

  • Treatment length depends on the complexity of your case. Minor corrections may be completed in as little as six months. More involved cases, particularly those addressing bite issues or significant crowding, can take 18 to 24 months. Dr. Pai will give you a realistic, personalized timeline after your iTero scan and treatment planning appointment. She does not rush cases to meet a target; she finishes when the result is right.

  • Most patients experience mild pressure when switching to a new set of aligners. This is completely normal and is a sign that the teeth are moving as planned. The sensation typically fades within one to two days. Unlike metal braces, there are no brackets or wires to cause cuts or irritation in the mouth. The vast majority of Dr. Pai's patients find the process far more comfortable than they expected.

  • Aligners should be removed before eating or drinking anything other than plain water. Food particles and colored beverages can stain the aligners and trap bacteria against the teeth, neither of which you want. The good news is that removing them takes seconds, and there are no restrictions on what you can eat throughout treatment. This is one of the most significant lifestyle advantages over traditional braces.

  • Both are doctor-led clear aligner systems with full clinical oversight from Dr. Pai. Invisalign has a longer track record, greater flexibility for complex cases, and is the better choice for patients with more advanced alignment or bite concerns.

    Candid Pro is designed for adults with mild to moderate needs and uses a hybrid in-office and remote monitoring model that is often more convenient and affordable. Dr. Pai will recommend the right fit for your situation at your consultation. She will never recommend the more expensive option when the simpler one will achieve the same result.

  • Yes, and this is one of the most common reasons adults pursue clear aligner treatment. Teeth naturally shift over time, especially when retainer use lapsed after orthodontic treatment. Invisalign and Candid Pro can efficiently re-align teeth that have moved since previous treatment. In many cases, these are faster and simpler cases than initial alignment treatment because the range of correction needed is smaller.

  • Your first visit is personal and thorough. Dr. Pai reviews your smile goals, bite, oral health, and long-term cosmetic plans before recommending Invisalign or Candid Pro. The goal is not just straighter teeth, but a healthier, more balanced smile that fits your face and ages well.

  • Not at all. Dr. Pai has successfully treated patients in their 70s and 80s with Invisalign. As long as your gums and underlying bone structure are healthy, there is no upper age limit for clear aligner treatment. In fact, many older adults find that straightening their teeth has a profound impact on their confidence and oral health, and wish they had done it sooner.

  • In most cases, before. Veneers placed on properly aligned teeth require less preparation, achieve a more natural result, and last significantly longer. If you are planning a broader smile transformation that includes both straightening and veneers, Dr. Pai will map out the ideal sequence at your consultation and coordinate the two treatments as part of a comprehensive plan. This is one of the advantages of working with a cosmetic dentist who offers both services under one roof.

  • Invisalign treatment in the Bay Area typically ranges from $6,000 to $9,000 depending on the complexity of the case and the length of treatment. Candid Pro is generally more affordable. Dr. Pai provides a transparent, itemized treatment plan with full pricing at your consultation. Financing options are available. Please ask at your appointment.

  • Retainers. This step is essential and non-negotiable. Teeth have a natural tendency to return toward their original positions over time. Retainers are what hold the result permanently. Dr. Pai provides retainers at the completion of every case and gives detailed guidance on how and when to wear them. Patients who wear their retainers as directed protect their investment for life.
