The honest answer is: usually four to eight years before it needs a refresh — but that range hides a lot, and most of it is within your control.
Composite bonding is tooth-coloured resin, hand-sculpted onto your own teeth. It is one of the kindest cosmetic treatments there is, because nothing is drilled away. But composite is not porcelain, and it is not indestructible. It picks up stain, it can chip, and over time it loses a little of its polish.
What shortens it
Three things do most of the damage:
- Staining habits. Coffee, tea, red wine and — worst of all — smoking will dull bonding faster than anything else.
- Grinding. If you grind your teeth at night, the biting edges of bonding wear and chip. A night guard is the single best protector.
- Skipping hygiene visits. A professional polish every six months keeps bonding bright and lets us catch a small chip before it becomes a big one.
What lengthens it
Rinsing with water after staining drinks, using a straw where you can, wearing a guard if you grind, and keeping up your hygiene visits will comfortably push most bonding towards the top of that range — and sometimes beyond.
Refreshing, not replacing
Here is the good news that porcelain cannot offer: bonding can usually be re-polished or added to rather than replaced. A quick refresh appointment brings it back to life for a fraction of the original cost. That is exactly what our Longevity & Care Forecast is built to show you — feed in your own habits and it estimates your refresh interval and a realistic ten-year cost.
