Orthodontic braces are corrective dental devices used to straighten teeth and align a person’s bite, addressing issues from crowded teeth to improper jaw relationships. The treatment corrects malocclusions, or misalignments of the teeth, to improve both oral health function and cosmetic appearance. This analysis provides an updated snapshot of how many people are currently undergoing orthodontic care and highlights the demographic shifts driving these numbers.
Current Prevalence Data
The number of people in the United States undergoing active orthodontic treatment has reached a record high. The American Association of Orthodontists (AAO) estimated that the total number of patients in active treatment across the U.S. and Canada is approximately 6.66 million, based on 2024 data. This figure demonstrates a growing demand for tooth alignment procedures, with approximately 4.5 million people in the U.S. receiving care at any given time. While not every person with misaligned teeth seeks treatment, about 50% of people have malocclusions severe enough to warrant orthodontic care.
Age Group Breakdown and Usage Trends
Orthodontic treatment is traditionally associated with adolescence, and this age group still accounts for the majority of patients. In 2022, U.S. AAO members were treating an estimated 3.15 million patients aged 8 to 17, representing about 7.4% of that age range’s population.
A notable trend is the increasing number of adults seeking treatment, who now represent a substantial portion of the patient population. Earlier AAO estimates showed adults accounted for approximately 27% of all U.S. and Canadian orthodontic patients. More recent data indicates this percentage is increasing, with some sources reporting that adults make up one in three orthodontic patients.
The total estimated number of adult patients being treated in the United States by AAO members is approximately 1.91 million, a rise from the 1.64 million reported in 2022. This upward trend has been consistent over the last decade. Although the highest number of adult patients are in the 18 to 30 age range, older adults are also increasingly seeking orthodontic care.
Factors Influencing Orthodontic Treatment Rates
The recent surge in orthodontic patient numbers, particularly among adults, is influenced by several interconnected factors. A primary driver is the technological advancement in discreet treatment options, such as clear aligners. These nearly invisible alternatives address the aesthetic concerns that historically deterred many adults from pursuing metal braces.
The market for invisible orthodontics has seen growth, with clear aligners holding the largest share. The convenience of clear aligners, which require fewer and shorter in-office visits, also appeals to working adults. Furthermore, a heightened societal emphasis on the cosmetic appearance of a straight smile, often fueled by social media, contributes to demand.
Financial accessibility also plays a role in the rising treatment rates. Many orthodontists offer flexible payment plans, and dental insurance that offsets costs makes treatment more attainable. Data shows that a majority of those who use orthodontics have a family income of $100,000 or more, suggesting financial resources remain a strong determinant in the decision to seek care.
