The market is forecast to grow at roughly 30 percent a year through 2030, and one of Kuwait’s highest-tier Invisalign providers argues the result depends on the doctor who plans the case, not the appliance itself.
Clear aligners have become one of the fastest-compounding corners of private healthcare spending in Kuwait. Grand View Research estimates the country’s clear aligner market will grow at a compound annual rate of 30.2 percent to reach USD 145.9 million by 2030. The global picture is the same story at scale: the firm values the worldwide market at USD 5.5 billion in 2025, on its way to USD 17.9 billion by 2033, with adults generating 65.1 percent of revenue. Align Technology, the maker of Invisalign, reported crossing 22 million cumulative patients in 2025, served by more than 295,000 trained doctors worldwide.
Numbers of that size have taught patients to shop for orthodontics the way they shop for a consumer product: a brand, a price, a timeline. Dr. Sarah Merza, a Kuwaiti consultant in orthodontics and dentofacial orthopedics who practises at the Invisalign Center by Sky Dental in Salmiya, argues that framing gets the treatment backwards.
“Do you think every clear aligner gives you the same result? That is not true,” she said, addressing patients in Kuwaiti Arabic. “With the Merza Method technique, rest assured that I use scientific foundations, with taste and refinement, for your smile. You can be certain that every smile will come out beautiful and suited to you personally.”
One Product, Many Treatment Plans
Merza trained at the University of Dundee and UCL’s Eastman Dental Institute, and holds membership qualifications from the Royal Colleges of Surgeons in Ireland and England. Her practice lists her as an Apex and Blue Diamond Invisalign provider, tiers Align assigns on the basis of treated case volume, with Blue Diamond generally described as covering roughly the top 1 percent of providers worldwide, and it records her as Top Invisalign Female Provider in Kuwait for 2024.
Her argument is structural rather than promotional. The aligner itself is manufactured plastic. The treatment is the plan behind it: which teeth move, in what sequence, how far at each stage, and what the finished bite and smile line should look like on that particular face. Two doctors prescribing the same system can submit entirely different plans for the same mouth, which is precisely why the manufacturer grades its providers at all. Merza has formalised her own planning approach as the Merza Method, which the practice describes as combining digital smile design with Invisalign biomechanics to refine shape and alignment without veneers or invasive procedures. Its tagline compresses the thesis to four words: designed, not just aligned.
The Market Already Ran the Experiment
The clearest evidence that the clinician is not an interchangeable part came from the industry’s own attempt to remove one. SmileDirectClub built a direct-to-consumer model around mail-order aligners with minimal in-person supervision, reached a valuation of about USD 8.9 billion at its 2019 listing and served more than two million customers. It filed for Chapter 11 protection in September 2023 carrying close to USD 900 million in debt, and shut down its global operations that December, leaving customers mid-treatment. The collapse had financial causes as well as clinical critics, but it ended the strongest version of the idea that the product alone is the treatment.
The Extraction Question
Nothing separates a treatment plan from a template like the decision to remove healthy teeth. The longest-running dataset comes from the University of North Carolina, where extraction featured in 30 percent of orthodontic cases in 1953, peaked at 76 percent in 1968, and had fallen to about 25 percent by 2011 as mechanics, materials and aesthetic thinking changed. Merza says the same shift is visible in her clinic, and that patients still fear the word more than the fact.
“The moment you hear the word extraction, you fall apart in my clinic,” she said. “Keep in mind that it has now become very rare for us to extract teeth in orthodontic cases. But if I do tell you extraction, you have to understand that there was no other solution in front of us. And in the end, the result will still be beautiful and suited to you, and most importantly, it will be healthy.”
That answer carries both halves of the judgment the aligner era demands: knowing how far modern techniques can go to avoid extraction, and telling the patient plainly when they cannot.
What the Tier Measures, and What It Does Not
One caveat belongs in any honest account of provider rankings. Align’s tiers are the manufacturer’s own designations, and they track treated case volume rather than independently audited outcomes. They signal experience; they do not guarantee a result. That caveat, though, lands close to Merza’s own argument: no badge, and no brand of plastic, substitutes for the diagnosis.
Kuwait’s market arithmetic points in one direction. Adult demand is rising, more providers will enter, and the marketing will grow louder. The useful question for patients is shifting from which aligner to whose plan.
