Orthodontic Relapse: Why It Happens and How to Prevent It

Woodhill Dental Specialties07/31/26

Why does orthodontic relapse happen in kids, and how do you stop it? Your child’s teeth may move once their braces or clear aligners are removed for several reasons. It’s why it’s so important for your child to wear their retainers as prescribed. 

Woodhill Dental Services treats children of all ages, including those whose teeth have moved after treatment. Have your child’s teeth moved after treatment? It can be fixed more easily than you think. 

What Is Orthodontic Relapse? 

What do we mean by orthodontic relapse, and what causes it? Orthodontic relapse refers to teeth moving after orthodontic treatment with braces or clear aligners. Let’s explore why teeth move after orthodontics. 

Why does this happen? Teeth aren’t locked into the jaw. Instead, they are held there by periodontal ligaments. Those ligaments loosen so braces or clear aligners can move the teeth. Once those braces or clear aligners come off, the ligaments take time to tighten up again. Instead, they may pull the teeth back to their old locations. 

This is why wearing retainers is so important. It holds the teeth in place while the ligaments tighten up again. 

Also, a child’s jaw is still developing and growing, which may cause the teeth to shift after braces in kids. 

Two-Phase Treatment for Kids

Woodhill Dental Specialties offers two-phase treatment for kids, so that we can guide jaw development to make braces or clear aligner treatment easier later on, or even less necessary. The first phase, usually around 9-10 years old, involves using orthodontic appliances to reshape the jaws. The second phase usually happens a few years later, between 11-14 years old

For example, children with a narrow upper jaw may get a palate expander to widen the jaw as it grows and develops. This prevents tooth crowding, which would have to be fixed with braces or clear aligners later. 

Other reasons for teeth shifting:

  • Bruxism (teeth grinding)
  • Changes in jaws due to injuries
  • Biting and chewing changes due to TMJ/TMD (temporomandibular joint disorder)
  • Wisdom teeth eruption or impaction
  • Not wearing retainers properly

Can Teeth Shift Even With Retainers?

Yes, teeth can shift if there is a problem with the retainers fitting properly. If they aren’t worn long enough in the beginning (20-22 hours a day), the teeth can shift. The first 3-6 months will be the most important to wear the retainers most of the time, removing them only for eating, brushing, and flossing teeth. 

They won’t shift overnight, so if retainers don’t fit properly, let us know right away, and we can bring you in to adjust them. 

How Do You Fix Shifted Teeth After Braces?

You can get braces again, but if the shifting is minor, clear aligners may be enough to do the trick! We can evaluate your child’s teeth and let you know. Clear aligners may be a quicker, easier method to repair their bite than using braces again. 

What’s Normal vs. What You Need to Fix

There may be slight shifting after orthodontic treatment that’s perfectly normal. If you’re concerned, it’s OK to call us and ask. We’d rather you call us right away than wait until it’s too late to stop the damage. The sooner we can fix things, the less damage there will be. 

What’s normal?

  • Very minor tooth position changes over months or years, especially in the lower front teeth
  • Slight crowding returning during growth spurts
  • Small changes in how the bite feels during jaw development

What’s worth calling about?

  • Pain or discomfort associated with tooth movement
  • Noticeable shift happening quickly (weeks rather than months)
  • Significant change in how teeth close together
  • A retainer that no longer fits at all

FAQs About Early Orthodontic Evaluation

How early will my child's orthodontic treatment start?

Children evaluated to be good candidates for two-phase orthodontic treatment can start as early as 9-10 years of age. We use orthodontic appliances to prepare their mouths for braces or clear aligners later, usually around ages 11-13.

Will my child get braces that first day?

It's very rare for a child to get braces the first day. There needs to be extenuating circumstances. Most of the time, we schedule braces for later.

How long will it take for my child to get braces?

Placing braces usually takes 1-2 hours. We clean the teeth, place the brackets, ensure the bonding agent dries and adheres properly, and then attach the archwire. We'll also talk to your child about caring for their braces, including what they can and cannot eat, how best to clean them, and other things they need to know for successful treatment.

Does my child really need to see an orthodontist if their teeth look straight?

Yes, because looks can be deceiving, and your child's teeth may not be as straight as you think. You need a professional orthodontist to properly evaluate their teeth.
