If you are researching clear aligners, one question probably comes up quickly: why do so many dentists and orthodontists recommend Invisalign clear aligners over every other option? The short answer is evidence.
Dentists and orthodontists recommend Invisalign treatment because it combines extensive clinical research, proprietary SmartTrack™ material, ClinCheck® 3D treatment planning, and doctor-supervised care. More than 23 million patients worldwide have been treated with the Invisalign System, giving providers confidence in treatment planning and outcomes.1
Is Invisalign treatment the #1 doctor-recommended clear aligner brand?
Yes. Invisalign is the #1 doctor recommended clear aligner brand (globally).2 That is not a marketing slogan. It comes from a global survey of 1,786 doctors (dentists and orthodontists who use clear aligners), conducted across North America, Europe, Latin America, and Asia-Pacific. No other clear aligner brand came close.
Why do so many doctors point to Invisalign clear aligners specifically? Trust is a big part of it. Invisalign is the clear aligner brand doctors trust most for teeth straightening.12 When practicing clinicians were asked which brand they trust most for their patients, Invisalign clear aligners were chosen most often at the 99% confidence interval. That level of professional consensus does not happen by accident.
How many patients have been treated with the Invisalign system?
Over 23 million patients have been treated worldwide with the Invisalign System.1 That makes Invisalign treatment the most widely used clear aligner system in the world, and the only brand to reach that milestone. Every one of those cases adds to a growing pool of real-world data that helps doctors treat the next patient more precisely.
This depth of experience matters. More cases mean more learning. The clinical insight gained from tens of millions of completed treatments gives Invisalign treatment providers a level of predictability and confidence that newer or smaller clear aligner brands simply cannot match. When your doctor recommends Invisalign clear aligners, they are drawing on decades of accumulated clinical knowledge.
Is Invisalign treatment the most clinically researched clear aligner system?
Yes. Invisalign is the most researched and clinically evaluated clear aligner system in the orthodontic industry.13 This is based on a comprehensive review of leading scientific publication repositories, including PubMed and Cochrane Library, conducted as recently as May 2025.
The majority of surveyed Invisalign orthodontists agree that the Invisalign System is the world’s most advanced clear aligner system.13 That consensus among working clinicians is significant. It means the doctors using the system every day share the same view as the published research: when it comes to evidence-based orthodontic care, Invisalign clear aligners lead the field. For patients, that means your doctor's recommendation is backed by the strongest body of clinical evidence available.
What is SmartTrack material, and why does it matter for your treatment?
SmartTrack material is the proprietary aligner material developed exclusively for the Invisalign system. It is what makes Invisalign clear aligners move teeth differently from other brands. Patented multi-layer SmartTrack material is clinically proven to improve tooth movement.3
Unlike the single-layer materials used by other clear aligner brands, SmartTrack material is engineered to apply the right amount of force at the right stage of treatment. Patients feel the difference. Aligners made from SmartTrack material provide better fit, better comfort, and are easier to insert and remove than Invisalign aligners previously made from single layer (EX30) material.14 A published patient survey found significant reductions in pain intensity, pain duration, and pressure upon insertion compared to the previous material. When you are wearing aligners 20 to 22 hours a day, that comfort difference is real and meaningful.
SmartTrack material is also built to last throughout treatment. SmartTrack material is four times more durable than single layer copolyester material.15 Invisalign aligners resist unwanted bending and warping, keeping your treatment plan on track.16 That durability helps ensure your aligners are delivering consistent force from the first day you wear each set to the last.
How do SmartForce™ features and SmartStage technology help treat more complex cases?
A common concern patients have is whether Invisalign clear aligners can handle their specific case. The answer, for the vast majority of patients, is yes. The combination of SmartTrack material with SmartForce features and SmartStage technology allows the Invisalign System to provide more predictable tooth movement than ever before.3
These proprietary innovations allow doctors to treat a much wider range of cases than many patients expect. Using proprietary innovations, such as SmartForce attachments, experienced Invisalign orthodontists are able to treat the majority of cases with Invisalign clear aligners that are treated with braces.17 For patients with a deep bite, the precision goes even further. SmartForce aligner activation improves clinical predictability of incisor intrusion in deep bite cases by up to 2X.18 This targeted clinical capability is exactly what allows doctors to recommend Invisalign treatment with confidence for cases that once required fixed appliances.
What is ClinCheck software, and how does it improve your treatment plan?
ClinCheck software is the digital treatment planning tool that every Invisalign treatment is built on. Before your first aligner arrives, your doctor uses ClinCheck software to map out every planned tooth movement in precise 3D detail and personalize your treatment plan. ClinCheck software is a powerful and sophisticated tool that supports treatment planning and monitoring.
This level of upfront precision leads to more predictable outcomes. In as little as 15 minutes, doctors can review initial treatment plans with ClinCheck Live Plan.19 That speed means your doctor spends less time waiting on plan delivery and more time reviewing, refining, and tailoring the approach to your specific case. The result is a treatment plan that is built around your smile, not a one-size-fits-all template.
Why do orthodontists feel so confident recommending Invisalign treatment?
The confidence doctors have in Invisalign treatment is not just a feeling. It is backed by data. 95% of orthodontists surveyed agree that the Invisalign system continues to raise the bar to help them confidently deliver more predictable treatment outcomes with Invisalign clear aligners.20 That is near-universal agreement among the orthodontists who use the system every day.
A big part of that confidence comes from continuous professional training. 96% of orthodontists surveyed agree that the training they receive from Align Technology helps elevate their product and practice knowledge of Invisalign clear aligners.21 Invisalign treatment providers have access to ongoing clinical education programs that keep them current on the latest techniques, materials, and capabilities. Your doctor is not just certified once. They are continuously trained as the system evolves.
This commitment to clinical improvement shows up in the outcomes too. 95% of doctors agree that Invisalign predictability has significantly improved due to clinical innovations in the past 5 years.22 Every patient treated today benefits from years of accumulated data and engineering refinement.
Are at-home or mail-order aligners as safe as doctor-supervised Invisalign treatment?
No. At-home or mail-order clear aligners skip the clinical oversight that makes orthodontic treatment safe. Without an in-person exam, X-rays, or ongoing monitoring by a trained clinician, problems like root resorption, bite changes, or bone stress can go undetected until significant damage has occurred.
Invisalign treatment is only available through certified dentists and orthodontists. Every treatment starts with a thorough clinical evaluation and continues under professional supervision throughout. Your doctor monitors your progress, adjusts your plan as needed using ClinCheck software, and ensures your teeth are moving safely and as planned. That level of professional involvement is something no at-home aligner brand can provide. It is a key reason why the doctor community trusts Invisalign clear aligners so strongly.
Does Invisalign treatment mean fewer trips to the dentist?
Yes, on average. Invisalign patients require on average 30% fewer doctor visits than fixed appliance patients.7 Fewer in-office adjustments mean fewer days off work or school and less time in waiting rooms.
This is possible because Invisalign clear aligners are designed to be changed at home on a regular schedule. There is no need for manual wire adjustments at every appointment. Your doctor still checks your progress at key milestones, but the overall visit frequency is lower by design. For busy adults, parents, and anyone juggling a full schedule, that convenience is a real advantage of Invisalign treatment.
Is Invisalign treatment more comfortable than braces?
For most patients, yes. Patients treated with traditional fixed appliances reported greater discomfort than patients treated with Invisalign clear aligners.6 That finding comes from a randomized, prospective clinical trial, representing some of the most rigorous evidence available in orthodontic research.
The comfort advantage goes beyond just pain levels. Adults treated with Invisalign clear aligners experienced less pain and fewer negative impacts on their lives during the first week of orthodontic treatment than did those treated with fixed appliances.23 This includes functional, psychosocial, and pain-related quality of life. For patients who feel anxious about starting treatment, knowing the clinical evidence supports Invisalign clear aligners for comfort can make a meaningful difference.
Patient satisfaction reflects this too. Invisalign patients are more satisfied with their overall experience than metal braces patients.11
Can Invisalign treatment work faster than braces?
Yes. Multiple studies have found that Invisalign treatment completed 5 months faster on average than treatment with braces.8 This is the finding of multiple independent peer-reviewed studies comparing treatment duration head to head.
Five months is a meaningful difference. It is five fewer months of orthodontic appointments, five fewer months of dietary restrictions, and five fewer months of waiting to see your finished smile. That faster timeline is one of the concrete, evidence-backed advantages doctors point to when recommending Invisalign treatment.
Does Invisalign treatment support better oral health during treatment?
Yes. Because Invisalign clear aligners are removable, patients can brush and floss normally throughout their entire treatment. That is something that is notoriously difficult to do well with fixed appliances. The clinical data confirms the difference. Invisalign treatment supports better oral health when compared to patients in treatment with fixed orthodontic appliances.9 Multiple peer-reviewed studies have shown lower plaque index scores, reduced probing depth, and less bleeding on probing among patients using Invisalign clear aligners compared to those wearing braces.
Straightening your teeth should not come at the cost of your gum health. With Invisalign treatment, you can pursue a better smile without compromising the health of your teeth and gums along the way.
Is Invisalign treatment affordable compared to braces?
It may cost less than you think. Invisalign aligners may cost the same or less than braces. Find a doctor and ask about cost, insurance, and payment plans.24 A survey of active US doctors found that more than half reported Invisalign treatment costs the same or less than traditional braces. Many dental insurance plans that cover orthodontic treatment also apply to Invisalign clear aligners. Most providers also offer flexible payment options.
The best way to know what Invisalign treatment will cost for your specific case is to book a consultation with a certified Invisalign provider. They can give you a personalized estimate, walk you through your insurance coverage, and explain any payment plans available to you.
Is Invisalign treatment a good option for kids and teens?
Yes, and teens often prefer it. Teens are more likely to choose Invisalign clear aligners among leading competing aligners for teeth straightening treatment.25 That matters because teen compliance with orthodontic treatment comes down to how they feel about wearing it day to day. Aligners that are nearly invisible and easy to remove for eating, sports, and social situations fit more naturally into a teenager's life.
Parents share that preference. Moms are more likely to choose Invisalign clear aligners among leading competing aligners for teeth straightening treatment.26 The removability of Invisalign clear aligners means teens can brush and floss normally throughout treatment, building better hygiene habits along the way.
For families navigating jaw development concerns alongside tooth alignment, 7 out of 10 surveyed parents of tweens and teens would prefer Invisalign treatment with mandibular advancement over braces.27 The ability to address both tooth alignment and jaw positioning with a single system, without separate bulky appliances, is a significant practical advantage for growing patients.
