From bite issues to patient compliance, discover what affects the length of treatment.
KEY TAKEAWAYS
- Most orthodontic treatment takes 18 to 24 months, but the range across patients is much wider, from 6 months for minor cases to 36 months for complex ones.
- Five factors drive nearly half of all variation in timeline, according to peer-reviewed research, and three of them are within your direct control.
- Bite complexity and biology set the starting line, but how you wear elastics, keep appointments, and care for your appliances determines how quickly you reach the finish.
- Patient compliance is the single biggest controllable factor. Missed appointments, broken brackets, and inconsistent elastic wear are the most common reasons treatments run long.
- We will give you a realistic timeline up front. At Gluck Orthodontics, our 40+ years in Nashville mean we can accurately predict the path ahead.
Introduction
Your daughter has barely settled into the chair in our Green Hills office before she asks the question we hear within the first sixty seconds of nearly every consult: "How long will I have to wear these?" We don't blame her. It is the most natural question in orthodontics, and the honest answer is the one most people don't expect: it depends on five specific things, and you actually have meaningful control over three of them.
Whether you live in Belle Meade, Brentwood, East Nashville, 12 South, Franklin, or anywhere across Middle Tennessee, the treatment timeline conversation is the same. At Gluck Orthodontics, Dr. Jono Gluck and Dr. Joel Gluck have been guiding Nashville families through this question for more than 40 years. This guide walks through the five factors that affect your braces timeline, what they actually mean, and what you can do to keep your smile journey on schedule.

The Honest Answer: It Depends on Five Things
Most orthodontic treatment takes 18 to 24 months. That's the answer you'll hear at almost any consultation. What that average hides, though, is that the actual range across patients is much wider. Minor cases can wrap up in 6 to 12 months. Complex bites can take 30 months or more. The difference comes down to five specific factors that we evaluate at your first visit and update as treatment progresses.
Here are those five factors, organized by how much control you actually have over each.
Factor #1: Your Starting Bite Complexity
This is the factor that sets the starting line of your treatment timeline. It is also the one you have the least control over.
FACTOR 1 Your Starting Bite Complexity (Mostly outside your control)
Can add or subtract 6 to 12 months from your timeline. Simple alignment cases finish in 6 to 12 months. Complex bite issues with crossbites, deep overbites, or jaw discrepancies routinely take 24 to 30 months.
Your starting bite reflects how your teeth and jaws developed, which is largely genetic. Crowding, spacing, overbites, underbites, crossbites, and open bites each carry their own typical treatment windows.
Get a thorough diagnostic workup at your first visit. We use 3D imaging and detailed records to map your specific case so we can give you an honest, evidence-based timeline up front. Knowing your starting point is half the battle.
Factor #2: Your Age and Jaw Growth
Age affects timeline in ways most patients don't expect. Younger patients often have advantages, but not always.
FACTOR 2 Your Age and Jaw Growth (Outside your control)
Can shift your timeline by 3 to 9 months. Patients who still have growth ahead can sometimes shorten treatment through growth modification. Adults with fully set bone structure may need longer for the same bite correction.
Children and teens in growth phases give us options that adults don't have, including jaw expansion and growth-modification appliances. Adults can still achieve excellent results, but treatment usually relies more on tooth movement alone, which can take longer for similar starting bites.
If you are a parent, schedule your child's first orthodontic check by age 7 (the age the American Association of Orthodontists recommends). Catching issues during growth opens up faster, less invasive treatment paths.
Factor #3: Your Treatment Type
The appliance you choose meaningfully affects the timeline, though the gaps may be smaller than internet forums suggest.
FACTOR 3 Your Treatment Type (Partially in your control (a decision we make together))
Can vary your timeline by 3 to 6 months. Modern Invisalign and traditional braces produce similar timelines for most cases, though specific bite types respond faster to one or the other.
Traditional braces give us the strongest control for complex movements and often run slightly faster for severe bites. Invisalign excels with mild to moderate cases and can produce comparable timelines when worn 20-plus hours per day.
Trust your orthodontist's recommendation based on your specific case. We will explain the timeline tradeoffs of each option honestly so you can make the right choice for your smile.

This is where patient choices start to dominate the timeline. Daily compliance is the single biggest variable that separates patients who finish on schedule from those who run long.
FACTOR 4 Your Daily Compliance (Fully in your control)
Can add 3 to 12 months to your timeline. Patients who wear elastics inconsistently, skip aligner trays, or repeatedly break brackets see treatment stretch well beyond their original timeline.
Compliance includes wearing elastics for the prescribed hours, wearing Invisalign aligners 20-plus hours daily, avoiding hard and sticky foods that break appliances, and maintaining excellent oral hygiene. Each of these directly impacts how predictably your teeth move.
Build retainer wear and elastic changes into a daily routine you already have (brushing teeth, getting ready for bed). Treat your treatment plan as a partnership: the work you do at home is at least half of the outcome.
Factor #5: Your Appointment Consistency
This is the most underrated controllable factor. Missed appointments are one of the most common reasons treatments run long.
FACTOR 5 Your Appointment Consistency (Fully in your control)
Each missed appointment typically adds 4 to 6 weeks to your timeline. Over an average treatment, three missed appointments can add 3 to 4 months on their own.
Each appointment is calibrated to the precise stage your teeth are at. When you miss an appointment, the planned next adjustment is delayed, and the teeth that were moving optimally may slow or settle in less-than-ideal positions before we can correct them at your next visit.
Schedule your next appointment before you leave the office, set calendar reminders, and reschedule promptly if life intervenes. Our team is happy to text appointment reminders, especially for families juggling school, work, and Nashville traffic.
What You Can Do to Stay On Track
Three of the five factors are fully in your control. Here is the short list of habits that keep treatment moving on schedule.
- Wear your elastics or aligners as prescribed, every day, for the full hours specified. This is the single biggest predictor of staying on timeline.
- Show up to every appointment, and schedule the next one before leaving the office. Three missed appointments can add three months.
- Protect your appliances at meals, avoiding hard candies, ice cubes, nuts, and other bracket-breakers. Each broken bracket means an unscheduled repair visit.
- Maintain excellent oral hygiene, with brushing after every meal and daily flossing. Gum inflammation slows tooth movement.
- Communicate with us early if anything is uncomfortable or unclear. Small issues are easier to address than big ones, and we are always a quick text or call away.

What is the average time for braces?
Most patients complete orthodontic treatment in 18 to 24 months. Minor cases can finish in 6 to 12 months; complex cases involving significant bite issues or jaw discrepancies can take 24 to 36 months. At your first visit, we provide a personalized estimate based on your specific case.
Can I shorten my treatment time?
Yes, in the factors you control. Wearing elastics or aligners exactly as prescribed, keeping every appointment, protecting your appliances, and maintaining excellent oral hygiene are the four habits most strongly tied to finishing on or ahead of schedule. We do not recommend so-called acceleration devices unless evidence supports them for your specific case.
Does Invisalign take less time than braces?
For many cases, treatment times are comparable. Invisalign tends to be slightly faster for mild to moderate alignment when patients wear aligners 20-plus hours daily. Traditional braces often run faster for complex bite corrections requiring strong, sustained tooth movement. We will recommend the option that fits your specific case and timeline goals.
What happens if I miss appointments?
Each missed appointment typically adds 4 to 6 weeks to your timeline. Three missed appointments can add 3 to 4 months. If life intervenes, contact us promptly to reschedule. We text appointment reminders and offer flexible scheduling, especially for families dealing with Nashville traffic and busy school calendars.
Will my treatment take longer because I'm an adult?
Sometimes, but not as much as people assume. Adults can achieve excellent results, but treatment often relies more on tooth movement alone (rather than growth modification), which can extend timelines for similar starting bites. The factors you control matter just as much for adults as for teens, so consistent compliance and appointment attendance keep adult cases on track.
