Spacers sit between 'Records' and 'Bond' — a short, achy prologue.
Spacers (separators) are small rubber rings slipped between the back teeth a week or so before braces go on, to open a sliver of space for the molar bands. They feel like a popcorn husk stuck between the teeth and produce a dull ache for two to three days. Not every case needs them — bonded molar tubes have replaced bands for many patients — but when they're used, they're the least-loved week in orthodontics.
Why they're needed
Molar bands — the metal rings that anchor the wire at the back — need a fraction of a millimetre of space to slide over tight back teeth. Spacers create it gently over a few days. Once the bands are on, the spacers are gone and the space closes around the band. We use bands where a case needs the strength — expanders, heavy bite mechanics, some teenage cases — and bonded tubes where it doesn't, which is increasingly often.
The week with spacers
- Days one to three: pressure between the back teeth; chewing on the front teeth feels better. Soft food, cold drinks, your usual pain relief if needed.
- Days four to seven: the ache fades as space opens. Many patients forget they're there.
- Brushing: normal, gently. Flossing: skip the spacer teeth — floss pulls them out.
- Foods: nothing sticky or chewy, which can dislodge them. The food list applies early.
If one falls out
Call us. If it's within a day or two of the banding appointment, the space may have opened enough already; if not, we'll replace it in five minutes. Don't try to reinsert it yourself. A spacer that's disappeared has usually been swallowed harmlessly or is somewhere in the pillow.
Frequently asked questions
Do spacers hurt more than braces?
Differently — a tight, dull ache between the back teeth rather than the tender-to-bite feeling of new braces. Most patients rank the spacer week as the least comfortable few days, and it's short.
Does everyone need spacers?
No. Bonded molar tubes have replaced bands for many cases. We'll tell you at the consultation whether yours needs them.
How long do spacers stay in?
Usually five to ten days, until the banding appointment.

If it were our own family
Soft food for three days, no flossing the back teeth, and a call if one falls out. We'd warn our own children that the spacer week is the least comfortable one and that it's short.

The bottom line
Tiny separators that open room for molar bands; a dull ache for three days; not every case needs them. Short, achy, and over before the braces go on.
