Mouthpiece Orthodontics Market Expands Rapidly: Survey Shows Over 70% of Users Are Highly Satisfied

Factumille, operated by PRIZMA Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Koki Sugimoto), a company providing a new form of marketing support that integrates PR and research, has published a survey report conducted between March and April.

Recently, there has been a noticeable increase in exposure to 'mouthpiece orthodontics' through TV commercials, SNS advertisements, and among friends. Compared to traditional wire braces, mouthpiece orthodontics offers overwhelming advantages such as being 'inconspicuous' and 'removable'. But what is the actual state of this market, and what kind of experiences are users having?

The Factumille editorial team, aiming to unravel societal trends based on 'facts', conducted an independent survey in March 2026 targeting 1,006 men and women in their 20s to 40s nationwide who have 'completed mouthpiece orthodontic treatment'.

Here, we introduce an excerpt from the article published on Factumille, exploring 'why the mouthpiece orthodontics market is growing now' and 'what characteristics are common among highly satisfactory mouthpiece orthodontic treatments'.

[Mouthpiece Orthodontics Market Fact Survey Report] Is the Market Expanding? Reasons for Popularity

Mouthpiece Orthodontics Users Increasing Since 2024

The 'Now' of the Market Shown by Treatment Start Date Data

First, let's look at market trends based on data regarding 'when' the survey respondents (those who have already completed mouthpiece orthodontics) started their treatment.

According to the survey results, the distribution of start periods is as follows:

- July 2025 - Present (2026): 4.3% - January 2025 - June 2025: 15.5% - July 2024 - December 2024: 21.6% - January 2024 - June 2024: 19.5% - July 2023 - December 2023: 11.5% - January 2023 - June 2023: 10.4% - 2022: 8.8%

According to this data, those who started in 2024 account for about 40% (41.1%) of the total. A sharp increase is observed from this year compared to 2023, indicating explosive growth in the market. The lower percentage from 2025 onwards is because this survey is limited to 'those who have completed treatment', and recent starters requiring several months to over a year are currently undergoing treatment and are not included. Considering this time lag, it can be inferred that the market has continued to expand steadily from 2025 to the present in 2026.

The 'Real Triggers' for People Starting Mouthpiece Orthodontics

So, why are so many people starting mouthpiece orthodontics? When asked, 'Please tell us the closest reason or trigger for deciding to undergo mouthpiece orthodontics,' the following results were obtained:

- Improvement of teeth appearance (32.8%) - Bite issues or discomfort (20.1%) - Dissatisfied with the outcome of previous orthodontic treatment (12.1%)

The top reason is indeed 'aesthetic improvement', accounting for about one-third of the total. In today's society, where opportunities to view one's own face objectively have increased due to the establishment of online meetings and SNS posts, the willingness to invest in the beauty of the mouth area is rising. The next most common reason is 'bite issues or discomfort'. This shows a spreading recognition of orthodontics not just for cosmetic purposes, but as a foundation for health. Furthermore, a certain number of people take the step to retreat due to dissatisfaction with previous orthodontic work. It is believed that the unique advantages of mouthpiece orthodontics, being 'transparent and inconspicuous', lower the psychological hurdle for trying again.

Over 70% Concentrated in High Ratings of 7 or More for Satisfaction with Mouthpiece Orthodontics

The survey revealed that one of the biggest reasons for such expansion in the mouthpiece orthodontics market is the 'overwhelmingly high customer satisfaction'. In this survey, when asked, 'How much would you recommend the brand of your mouthpiece orthodontics to your family and friends? (out of 10 points)', very surprising data was obtained.

- 10 points (Highly recommend): 8.3% - 9 points: 11.4% - 8 points: 25.3% - 7 points: 25.8%

The high-rating group scoring 7 points or above accounts for about 70% (70.8%) of the total. On the other hand, the dissatisfied group scoring 0 to 3 points is a mere 3.2%. Amidst a proliferation of various brands, there are no brands with significantly low satisfaction, suggesting that the industry as a whole maintains a very high quality.

Then, why is the satisfaction so high? The reason given is that 'the quality of the mouthpieces (aligners) is uniform'.*1 Traditional wire braces relied heavily on 'individual craftsmanship', such as the dentist's skill and experience in bending wires.
