Why Adult Orthodontic Treatment Has Changed

Twenty years ago, adults in braces were the exception. Today, they are a significant share of every orthodontic practice.

According to the American Association of Orthodontists’ 2025 Economics Survey, 27% of all U.S. and Canadian orthodontic patients are adults. That works out to approximately 1.9 million adults in active orthodontic treatment in the U.S. as of 2024, up from 1.6 million in 2022. Adult patient counts have grown by nearly 40% since the early 1990s.

Clear aligner technology is a major reason for this shift. Adults who would not have considered braces in their working years often find aligners practical in a way metal brackets aren’t: the trays come out for meals, they don’t show in professional or social settings, and the hygiene routine stays largely unchanged.

How Clear Aligners Actually Work

Clear aligners are medical-grade plastic trays custom-fitted to your teeth. Each tray in the series is slightly different from the last. Wearing each one for 1 to 2 weeks (your exact schedule depends on Dr. Laura Milnor’s treatment plan) moves your teeth incrementally toward their final position.

The process starts with a digital scan, not physical impressions. The scan feeds into a 3D model that generates your full treatment series and lets you see a simulation of the projected outcome before anything starts.

Attachments are common and often misunderstood. These are small, tooth-colored composite bumps bonded to specific teeth before treatment begins. They give the trays leverage for moving teeth that are harder to shift with tray pressure alone. Most patients stop noticing them within days. They do not show at conversational distance.

The AAO notes that aligners work best for mild to moderate crowding, spacing, and bite issues. Complex cases sometimes require braces, or a combination approach. Dr. Milnor will tell you clearly at the evaluation which applies to your situation.

Check-in appointments happen every 6 to 8 weeks. These visits are shorter than traditional ortho appointments because there is no wire adjustment involved. Dr. Milnor reviews progress, checks fit, and releases the next trays.

The Compliance Reality: What 20–22 Hours Means in Practice

This is the part most patients underestimate.

Clear aligners require 20 to 22 hours of daily wear. The trays only move teeth when they are in your mouth. Taking them out for meals, morning coffee, and evening brushing is the designed use case. Taking them out more than that extends your own treatment time.

The math is simple. Two extra hours out per day adds up to 60 hours per month. Over a 15-month treatment, that difference can push the finish line back by several months.

In practice: meals take about 20 to 30 minutes. Three meals a day, plus one or two coffee breaks, lands you right at the 2-hour-out window without trying. Snacking throughout the day is where the hours accumulate. Adults who graze or drink anything other than water throughout the day typically need to change that habit for clear aligner treatment to finish on schedule.

Clear Aligners vs. Braces for Adults: Where Each One Wins

Factor	Clear Aligners	Traditional Braces
Visibility	Virtually invisible in normal lighting	Visible brackets and wires
Eating	Remove to eat anything	Avoid hard, sticky, crunchy foods throughout treatment
Compliance variable	Must wear 20–22 hrs/day consistently	No wear variable; always working
Hygiene	Brush and floss normally; clean trays daily	Requires more time and tools around brackets
Complex cases	Best for mild-to-moderate cases	Handles the full range of complexity
Typical adult timeline	12–18 months	18–24 months
Cost range	Talk to our team for current Fort Collins pricing	Talk to our team for current Fort Collins pricing

Neither option is universally better. The right choice depends on case complexity, lifestyle, and what the patient will actually stick with.

An adult who travels frequently for work and would struggle to avoid hard foods during dinner may do better with aligners. An adult with a complex bite correction who needs precise tooth movement may get a better outcome with braces. This is the conversation to have with Dr. Milnor at your evaluation, not a decision to make based on a website.

What Results Look Like and What Protects Them Long-Term

Orthodontic treatment moves teeth. It does not keep them there.

Teeth shift throughout adulthood regardless of whether a person had orthodontic treatment. The forces that cause this include natural jaw development, chewing patterns, and tissue changes over time. A retainer counters those forces and keeps treated teeth in position.

The clinical standard after clear aligner treatment is full-time retainer wear (day and night) for the first several months, transitioning to nighttime wear indefinitely. Skipping retainers is the single most common reason teeth drift back after treatment. It is also the most preventable outcome in orthodontics.

Whitening is often considered after treatment completes. The right timing matters: enamel is slightly more porous immediately after orthodontic treatment. Dr. Milnor’s team can advise on the appropriate wait before whitening.

What Consultation Looks Like at Milnor Orthodontics

A consultation at Milnor is an evaluation, not a sales appointment. Dr. Laura Milnor reviews your bite and teeth, discusses what you want to achieve, and tells you what treatment would look like, including realistic timeline and cost. Most consultations are complimentary.

Adults in Fort Collins and surrounding Northern Colorado communities including Loveland and Windsor can book online at milnororthodontics.com or call (970) 484-3214. Evening appointments are available.

If you have been thinking about this for a while, the evaluation is the right next step. It takes about an hour, and you leave with a clear picture of what treatment involves for your specific situation.
