Spacers, also called separators, are tiny rubber rings placed between some back teeth a short time before braces. They open a little space so metal bands can fit around the molars. Not everyone needs them, only patients whose braces include molar bands or certain appliances.
Why are spacers needed?
Back teeth usually touch tightly. Some braces and appliances, such as palatal expanders, attach to the molars with a thin metal ring (a band) that wraps around the tooth. A spacer gently pushes the teeth apart just enough for the band to slide into place. The American Association of Orthodontists notes spacers are usually placed one to two weeks before the bands.
Do spacers hurt?
Spacers can feel like food stuck between your teeth, and the teeth may be sore for the first few days. Soft foods help, and an over-the-counter pain reliever you would normally use, taken as directed on the label, can help; ask your pharmacist or doctor if you’re not sure. The soreness usually eases as the space opens.
Eating and cleaning with spacers
- Avoid sticky foods like caramel and gum, which can pull spacers out.
- Chew carefully on the side with spacers.
- Brush normally, but don’t floss between the teeth that have spacers; floss can pull them out. Floss the other teeth as usual.
What if a spacer falls out?
This often happens as space opens up. Don’t try to put it back yourself. Call us the next business day and we’ll tell you whether it needs replacing before your next visit.
What happens next?
At your next visit, the spacers come out, which takes seconds, and the bands go on as part of your braces or appliance. The space usually closes again on its own afterwards.
