Spacers for braces: what they do and how to care for them

If your next orthodontic visit includes spacers, it helps to leave with three things clear: where they are, how to care for those areas, and when the team wants to see you again.

Why might you need spacers before braces?

Spacers, also called separators, create a little room between teeth before an orthodontic band is fitted. A band is a metal ring that goes around a tooth. The University of Toronto’s dental patient guide describes this preparation step: a small elastic separator is placed beside the tooth that needs a band.

Not every braces plan needs bands and separators. The University of Toronto describes bands as an option for particular situations. Ask which teeth need preparation and what happens at your next visit.

What can spacers feel like?

Pressure, tenderness, or sensitivity can occur during the first few days, and your bite may feel different. Nationwide Children’s Hospital describes these early sensations, but there is no exact day when everyone becomes comfortable. Soft, cool foods may make eating easier while the teeth are tender.

Contact your treating team promptly for excessive pain or swelling. Explain whether the discomfort is improving or getting worse and whether it is making eating difficult. Do not assume every new symptom is an expected part of treatment.

Severe pain with facial swelling or fever needs urgent assessment. Call 911 for trouble breathing or swallowing. These are AAO emergency warning signs; do not wait for a routine appointment or office reply.

How should you eat and clean around spacers?

Keep brushing normally, but avoid flossing the contacts where separators sit. Continue cleaning the other teeth as directed. Ask the team to show you the exact areas to leave alone and how to clean around them. Do not pick at or remove a separator to reach underneath it.

Avoid sticky or chewy foods such as gum, taffy, and caramel while separators are in place, following Nationwide’s separator-care advice. Plan a few softer meals or snacks you already enjoy.

Avoid hard foods too, such as hard candy or nuts, consistent with the AAO’s appliance-care advice. Follow any additional restrictions your treating team gives you.

Our patient-care page has broader everyday instructions. For this short preparation stage, make sure your cleaning plan specifically accounts for the separators.

What should you do if a spacer falls out?

Contact your orthodontic team before the next appointment and tell them when you noticed it was missing. NHS Fife advises that a missing separator may need an earlier appointment depending on timing. Let the team decide whether replacement is needed, even if the planned visit is close.

Do not try to reinsert it or put another band between the teeth. A missing spacer alone does not tell you whether the area is ready for the next step. Report the change rather than testing the gap yourself.

Have these details ready: the side of your mouth, when the spacer was placed, when you noticed it missing, your next appointment date, and any pain or swelling. If you are unsure which part came off, describe it and ask whether a photo would help.

Are spacers the same as other rubber bands?

The small colored ties around individual brackets hold the wire in place, as the AAO’s orthodontic glossary explains. Those ties have a different job from separators between teeth.

Prescribed removable elastics add force through attachment points chosen for your bite. You may be taught to put those on and replace them yourself. Those instructions do not apply to spacers. Use only the part and placement your team prescribed; do not use a spare elastic as a separator.

If you were given a packet of removable bands, our rubber-bands guide explains the questions to ask about that separate routine.

Prepare for your next appointment

Keep the appointment your team scheduled. When bands are fitted, the clinician removes the separators and checks the band fit, as described in the University of Toronto guide. You do not need to take them out beforehand.

Before leaving the spacer visit, ask:

• Which teeth have separators, and which contacts should I avoid flossing?
• What should I do if a spacer seems loose or disappears?
• What symptoms should make me call sooner?
• When is the next visit, and whom should I contact if I need to reschedule?

SC Orthodontics sees patients from across Santa Clarita at our Valencia office. Ask our team about spacer care if we are managing your treatment. If another office placed your separators, ask that team for instructions. Our orthodontic emergency guide covers other appliance problems and warning signs in more detail.
