Power chains: closing gaps, one connected elastic at a time

A power chain is a continuous strip of connected elastic rings stretched across a group of brackets. It replaces the individual ties on those teeth and adds a gentle, constant pull along the wire that draws the teeth together — closing gaps, consolidating spaces after extractions, or keeping aligned teeth snug while the bite is corrected. It's usually placed in the middle-to-late months of treatment and changed at each adjustment.

What it does

Brackets and wires align teeth but don't, on their own, pull them along the arch toward each other. A power chain supplies that horizontal force. Common jobs: closing the small gaps that open during alignment, consolidating the space left by an extraction, drawing a group of teeth back to correct a protrusion, and holding a corrected segment together while other movements finish. We'll tell you which job yours is doing and roughly how long it'll be on.

What it feels like

Tender for two or three days after it's placed, like a wire change; then nothing. Teeth may feel slightly "tight" as they draw together — that's the point. The chain loses strength over weeks and is replaced at each visit, often in the colour of your choice; power chains come in the full colour range, and a chain in a bold colour is a favourite among younger patients.

Care and staining

Like colour ties, chains can stain with coffee, tea, curry and turmeric — grey, smoke or darker colours hide it; clear shows it. They're replaced at every adjustment, so staining is a between-visits nuisance. Brush along the chain as you would along the wire; food catches under it more readily, so the after-meal rinse matters.

If it were our own family

We'd let our children pick the chain colour and remind them to rinse after meals — food catches under a chain more than under ties. Then we'd point out the gaps closing in the mirror, month by month.
