Invisalign has become a popular choice for straightening teeth without metal braces. These clear aligners are used by people of all ages. From young children to older adults, Invisalign suits many different lifestyles and dental needs.
But what is the average age of Invisalign patients? While there is no strict age requirement, data and trends show that most patients fall within a certain age range. In this article, we explore the typical age groups using Invisalign, treatment timelines by age, and how age can affect results.
The Average Age of Invisalign Users
On average, Invisalign patients are between 18 and 35 years old. This age group makes up the largest number of users worldwide. Many people start Invisalign in their late teens or early adulthood because this is when all permanent teeth have come in, and they want a more confident smile for university, work, or social events.
However, this does not mean that younger children or older adults cannot use Invisalign. Let’s look at each age group to understand how Invisalign fits into their lives.
What is Invisalign?
Invisalign for Children (Ages 6–10)
Invisalign First is a special option for children between the ages of six and ten. This stage is called Phase 1 treatment. It is used to guide jaw growth, create space for adult teeth, and fix early bite issues.
Most children in this group wear aligners for 8 to 12 months. Treatment is gentle and works with both baby and adult teeth. Parents usually bring their children in for an orthodontic check around age seven to see if they need early treatment.
Invisalign for Teenagers (Ages 11–17)
Teenagers are the most common Invisalign users. Many get aligners between ages 12 and 16. At this age, most permanent teeth are in place, and the jaw is still developing. This makes it easier and faster to move teeth into better positions.
Aligners for teens come with compliance indicators, which show if they are being worn enough. Most teens finish their Invisalign treatment in 6 to 12 months, depending on the case.
Teens enjoy Invisalign because it is nearly invisible, easy to remove, and fits their school and social life without the look of metal braces.
What Are the Benefits of Invisalign?
Invisalign for Young Adults (Ages 18–35)
This age group is considered the average or most typical group for Invisalign. People in their late teens and twenties often seek treatment for professional or personal reasons.
Whether it’s for a job interview, a wedding, or general confidence, many young adults prefer the clear, removable aligners that fit easily into their routine.
Treatment usually lasts 12 to 15 months for this group. Results tend to be quicker than in older adults but slower than in teenagers, as bone density is higher.
Invisalign for Adults (Ages 35 and Up)
Adults of all ages can benefit from Invisalign. In fact, many patients in their 40s, 50s, and even 60s are now choosing this treatment. There is no age limit for getting a straighter smile.
The main difference is that treatment may take longer for older adults. This is because the jawbone is fully developed and teeth are more set in place. On average, adult patients may need 12 to 18 months to complete their treatment.
However, adults tend to be more responsible with wearing their aligners for the required 20–22 hours a day, which helps ensure good results.
How Long Does Invisalign Take to Work?
How Age Affects Invisalign Treatment
Age does not stop you from getting Invisalign, but it can affect the speed and ease of treatment.
- Children and teens often finish treatment quicker due to softer bone structures and natural growth.
- Young adults have steady results with good habits.
- Older adults may take longer, but with commitment, they can still achieve excellent results.
Good oral health is also key. Regardless of age, healthy gums and teeth are needed for successful treatment.
Average Treatment Time by Age Group
| Age Group | Average Treatment Time |
|---|---|
| Children (6–10) | 8–12 months |
| Teenagers (11–17) | 6–12 months |
| Young Adults (18–35) | 12–15 months |
| Adults (35+) | 12–18 months |
These are average estimates. Every case is unique, so times may vary.
