In most cases, cavities should be treated before braces go on — but having a cavity doesn't automatically mean treatment has to wait long, and it definitely doesn't mean treatment is off the table.
The reasoning is straightforward: braces add brackets, wires, and bands that make certain areas of the teeth harder to clean, and untreated decay underneath that hardware can progress more quickly and become more complicated to treat. The good news is that addressing a cavity before braces is usually a quick, routine step — and if a cavity is discovered after braces are already on, that's manageable too.
This guide walks through what to expect at each stage: before treatment starts, during active treatment, and what happens if decay shows up along the way.
Before Braces: Why Cavities Are Usually Treated First
When you have an initial consultation for braces, your orthodontist will typically coordinate with your general dentist (or recommend a visit if you haven't had one recently) to make sure your teeth are in good shape before brackets go on. Here's why this step matters:
Brackets and bands cover part of the tooth surface. Once a bracket is bonded to a tooth, that area becomes much harder to treat if a cavity is found underneath it later. Addressing decay beforehand means it's fully visible and accessible.
Decay can progress faster once cleaning becomes more difficult. Braces inevitably create more nooks where food and plaque collect. A cavity that was small and manageable can advance more quickly in this environment if it's left untreated.
A filled tooth is just as ready for braces as one that never had a cavity. Once a cavity is filled, that tooth functions normally for orthodontic purposes — brackets bond to fillings just as well as to natural enamel in most cases.
Does Treating a Cavity First Delay Getting Braces?
Usually only briefly. A standard filling is typically a single, routine appointment with your general dentist, and most orthodontic offices can work around this timeline without significant delay. For most patients with one or a few small to moderate cavities, treatment can be completed and braces can move forward on schedule or with only a short adjustment to the start date.
The exceptions are larger or more involved cases. If a cavity is extensive — deep decay requiring a root canal, or a tooth that needs a crown — this naturally takes longer and may shift the timeline more. Your orthodontist and dentist will coordinate to determine the right sequence, but even in these cases, the goal is simply to make sure each tooth is healthy and stable before it takes on the pressure of orthodontic movement.
Very small, early-stage spots are sometimes monitored rather than treated immediately if your dentist determines they're not yet at the point of needing intervention — but this is a judgment call made by your dentist, not something to decide on your own.
During Treatment: What If a Cavity Develops with Braces On?
This is one of the most common questions, and the short answer is: yes, cavities can absolutely be filled while you have braces — your braces do not need to come off.
Here's how it typically works:
- Your dentist will work around the bracket and wire to access the affected tooth
- In most cases, the bracket stays in place and the filling is completed around it
- In some situations, the bracket on that specific tooth may be temporarily removed to allow full access, then re-bonded once the filling is complete
- The rest of your braces and treatment continue as normal — this doesn't restart or significantly delay your overall timeline
If you notice sensitivity, a visible dark spot, or discomfort in a specific tooth during treatment, let both your orthodontist and your dentist know. Catching it early keeps the fix simple.

Why Cavity Prevention Matters More with Braces
Since braces make certain areas of the teeth harder to clean, prevention becomes especially important during treatment. The good news is that the same habits that prevent cavities in general are simply more important — not different — once braces are on:
- Brushing after every meal, with attention to the areas above and below each bracket
- Flossing daily using a floss threader, orthodontic super floss, or water flosser to reach between teeth and around wires
- Fluoride toothpaste and mouthwash, which strengthen enamel against the additional plaque-trapping surfaces braces create
- Limiting sugary and sticky foods, which are both harder to clean away and more likely to feed the bacteria that cause decay
- Keeping up with regular dental cleanings every 6 months during treatment, in addition to your orthodontic adjustment appointments

Can You Get Braces If You Already Have Fillings?
Yes, without any issue. A filled tooth is treated the same as any other tooth for orthodontic purposes. Brackets bond to fillings normally, and the tooth can be moved through treatment just like a tooth that never had a cavity. The only consideration is that your orthodontist will check that any fillings are intact and stable before bonding — if a filling is old or showing signs of wear, it may be worth having your dentist evaluate it first, simply as good general dental care rather than anything braces-specific.
What If a Cavity Is Found at a Routine Dental Visit During Treatment?
Many patients see their general dentist for cleanings every 6 months throughout orthodontic treatment, separate from their orthodontic adjustment visits. If a cavity is found at one of these visits:
- Your dentist will let you know the recommended treatment and timeline
- In most cases, the filling can be scheduled and completed without pausing your orthodontic treatment
- Your orthodontist doesn't need to be involved in the filling itself, but it's a good idea to mention it at your next adjustment, especially if a bracket needed to be temporarily removed
This kind of coordination between your dentist and orthodontist is normal and routine — both offices are used to working together this way.
Frequently Asked Questions
Can you get braces with cavities?
In most cases, cavities are treated before braces are placed, since brackets and wires make decayed areas harder to access and treat later, and can make cavities progress faster. However, having a cavity doesn't disqualify you from braces — it simply means addressing the cavity is typically the first step, often with only a brief delay to the overall timeline.
Do cavities need to be treated before braces?
Generally yes, especially for moderate to significant cavities. Treating decay first ensures each tooth is healthy and stable before taking on the pressure of orthodontic movement, and avoids having decay trapped under a bracket. Very small, early-stage spots may sometimes be monitored at your dentist's discretion rather than treated immediately.
Can you get a cavity filled with braces on?
Yes. Cavities can be filled while braces are in place, without removing the braces entirely. In most cases, the dentist works around the bracket and wire to access the tooth. In some cases, the bracket on that specific tooth may be temporarily removed and then re-bonded after the filling is complete. This doesn't significantly affect your overall treatment timeline.
Does getting a cavity filled delay starting braces?
Usually only briefly — a standard filling is typically a single routine appointment and most orthodontic timelines can accommodate this without significant delay. More extensive treatment, like a root canal or crown, naturally takes longer and may shift the start date more, but your orthodontist and dentist will coordinate to keep things on track.
Can you get braces if you have fillings?
Yes, with no issue. Brackets bond to filled teeth the same way they bond to natural enamel, and filled teeth move through treatment normally. Your orthodontist will simply check that existing fillings are intact and stable before bonding.
Do people with braces get cavities more easily?
Braces themselves don't cause cavities, but they do create more surfaces and small spaces where food and plaque can collect, making thorough cleaning more important. With consistent brushing after meals, daily flossing, and regular dental visits, the cavity risk with braces is very manageable.
What happens if I find out I have a cavity partway through braces treatment?
Let both your dentist and orthodontist know. In most cases, the cavity is filled in a routine dental appointment — sometimes working around the bracket, sometimes temporarily removing and re-bonding it — and your orthodontic treatment continues on schedule without significant disruption.
