Yes, you can get braces twice. In fact, orthodontic retreatment is more common than many people think. Teeth can shift after braces for several reasons, and a second round of treatment may be the right step when that movement is no longer minor or stable. In some cases, the fix is relatively simple. In others, it takes a more complete retreatment plan.
What matters most is understanding why the teeth moved and what kind of correction will hold up better this time. A retainer may be enough in some situations. In others, braces or Invisalign make more sense. Teeth can move after treatment, and orthodontists often use retainers to help preserve the result over time. At Carvalho & Roth Orthodontics, retreatment is planned around what caused the shift and what will give the smile the best long-term stability moving forward.
Why do people need braces a second time?
There is no single reason. Some people stop wearing their retainers consistently. Some wear them for a while and then gradually fall out of the habit. Others had treatment years ago and noticed slow movement as time passed. Even people who were careful after braces can still see changes over time, especially if the bite was under tension, wisdom teeth became part of the conversation, or the teeth were always prone to crowding.
That is why retreatment should not be treated like a failure. It is usually just a sign that the teeth did not stay exactly where they were meant to without continued support. In many cases, the earlier that movement is addressed, the easier the correction can be.

Can a retainer fix shifted teeth, or do braces have to come back?
That depends on how much movement has happened.
If the change is very minor, a retainer may help keep things from getting worse, and in some cases a new retainer may be part of the solution. But a retainer is mainly designed to maintain tooth position, not actively move teeth back into alignment. If the teeth have already shifted in a noticeable way, retreatment may be the better answer. That is the difference between retention and active treatment. Invisalign moves teeth. Retainers hold them in place.
This is often where people lose time. They hope the problem is small enough to ignore, or they assume wearing an old retainer again will fully fix it. Sometimes that works for a very limited shift. Often, it does not.
What are the options if you need braces a second time?
The best option depends on how much correction is needed, how the bite looks now, and what kind of treatment fits daily life best.
Traditional braces
Braces are still one of the most effective tools for retreatment, especially when the teeth need more detailed control. They can be a strong option when the bite has changed, the crowding is more significant, or the movement is not limited to one or two teeth. Different types of braces may be used depending on the goals of treatment and the level of visibility a patient is comfortable with.
Invisalign
For some patients, Invisalign can be a good second-time treatment option. It is often appealing when the relapse is mild to moderate and the patient wants a lower-profile approach. It can also be a practical fit for adults who had braces years ago and now want correction that feels more discreet.
Limited retreatment
Not every second round of treatment has to look like the first. Some patients need full retreatment. Others only need a shorter phase focused on the teeth that moved. The answer depends on how much changed and whether the bite stayed stable overall. The American Association of Orthodontists notes that when teeth have shifted, some patients may need only a short round of braces or clear aligners, while others may need more comprehensive retreatment.
Is getting braces twice more common in adults?
It often is, mainly because adults have had more time for relapse to show up.
Someone who finished braces as a teenager may not notice meaningful movement until their twenties, thirties, or later. That does not make retreatment unusual. It just means the original result was being tested over a longer period of time. For adults dealing with crowding, spacing, or bite changes after earlier treatment, adult treatment can be planned around both the smile and the demands of daily life.
Second-time treatment is also common among adults who were never completely happy with their first result, stopped treatment early years ago, or had changes that slowly became harder to ignore.
Does a second round of braces take as long?
Not always.
Some retreatment cases move faster than the first round because the problem is more limited. A small relapse may take much less time than comprehensive first-time treatment. But that is not guaranteed. If the bite changed significantly, multiple teeth shifted, or the original problem was more complex than it seemed, treatment may still take time.
The important thing is not to assume that braces twice means starting over from zero. In many cases, it is more accurate to think of it as a correction or refinement phase rather than a complete repeat of the past.
Does retreatment cost the same as the first time?
It can, but it often depends on scope.
A short phase of retreatment may cost less than full comprehensive treatment. A more involved correction may be closer to the cost of regular braces or aligner treatment. The biggest factors are how much movement is needed, whether the bite also needs correction, what appliance is being used, and how long treatment is expected to take.
That is one reason it helps to have the teeth evaluated early. Waiting usually does not make relapse cheaper or easier to manage.
How do you keep teeth from moving again after retreatment?
This is the part that matters most in the long run.
Teeth need support after they are moved. Without that support, relapse becomes more likely. That is why the retention phase matters so much after braces or Invisalign. The goal is not just to finish treatment. It is to protect the result.
A few habits make a real difference:
- wear retainers exactly as directed
- replace broken or worn retainers instead of trying to get by without them
- do not assume a tight retainer is “close enough” if the teeth have already moved
- get movement checked early instead of waiting for it to become more obvious
- treat retention as part of treatment, not something separate from it
Patients comparing long-term maintenance options may also find it helpful to read about Invisalign vs. retainer, especially when the question is whether the teeth need movement or just better support.
When is it time to come in for an evaluation?
The best time is when the movement first becomes noticeable.
If teeth have shifted, the bite feels different, spacing has opened up, or crowding is returning, it is worth getting checked before the change becomes more advanced. That does not automatically mean full braces are coming back. It means the problem can be evaluated while the options may still be simpler.
At Carvalho & Roth Orthodontics, retreatment is planned around what changed, why it changed, and what will hold the result more reliably moving forward. Dr. Roberto S. Carvalho, D.M.D., PhD, and Dr. Menachem D. Roth, D.M.D., MMSc, bring the kind of orthodontic training that matters when treatment needs to be tailored rather than repeated blindly.
For patients considering braces a second time, that means looking closely at tooth movement, bite stability, and retention strategy before deciding whether braces, Invisalign, or a more limited correction makes the most sense.

FAQs
Can you really get braces twice?
Yes. A second round of braces is possible and often very effective when teeth have shifted after earlier treatment.
Do teeth always move after braces?
Not always in a dramatic way, but some movement over time is common. That is why retainers are such an important part of protecting the result.
Is Invisalign better than braces the second time?
Sometimes, but not automatically. Invisalign can be a good option for mild to moderate relapse, while braces may be better when more control is needed.
Will I need full braces again if my teeth shifted?
Not necessarily. Some patients need comprehensive retreatment, while others only need a shorter correction focused on the teeth that moved.
Can an old retainer move teeth back?
Usually not in a predictable or complete way. Retainers are mainly meant to maintain position, not fully correct relapse once it has already happened.
