Short answer: cosmetic bonding usually lasts somewhere between 5 and 10 years before it needs a touch-up or a redo. Where it is in your mouth, how you bite, and your daily habits make the biggest difference. If you avoid chewing ice, biting your nails and drinking a lot of coffee without rinsing, it tends to last toward the longer end.
What is bonding, exactly?
Bonding is a tooth-colored resin that’s shaped by hand right on your tooth and hardened with a special light. We use it to fix chips, close small gaps, and even out teeth that are a little too short or uneven. Most of the time it’s done in one visit. There’s more detail on our dental bonding page.
Why does bonding wear out?
Bonding is tough, but it isn’t as hard as your natural enamel or as porcelain. Over the years it can pick up small chips or lose some of its shine. When we see bonding fail early, it’s usually down to habits rather than the material. The usual suspects are biting nails or pens, chewing ice, grinding at night, using your teeth to rip open packages, and a lot of coffee, tea, red wine or smoking.
How do you make it last longer?
A few simple things go a long way. If you grind or clench, a night guard is the single best way to protect bonding. Rinsing with water after coffee or red wine helps keep stains from setting in. Keep up with your cleanings, because that’s when we polish the bonding and catch little chips before they grow.
And if you’re thinking about whitening, do it before the bonding goes on. Bonding doesn’t lighten with whitening, so it’s matched to whatever shade your teeth are on the day it’s placed.
How often should someone check it?
We look at it at every cleaning, which for most people means twice a year. We check the edges, polish off surface stains, and make sure your bite isn’t putting too much pressure on it. A rough edge caught early often just needs a quick polish.
If you notice a sharp spot, a change in color, or something that feels different when you bite, don’t wait for your next cleaning. Give us a call.
Can old bonding be repaired instead of replaced?
A lot of the time, yes. Small chips can usually be smoothed or built back up in a short visit, which is quicker and cheaper than starting over.
Would veneers be a better choice?
For some people. Porcelain veneers often last 10 to 15 years or more with good care, and they resist stains much better. They cost more, $1,795 to $2,200 per tooth at our office, but you replace them less often. If you’re weighing the two, our cosmetic dentistry page compares them, and the ADA’s guide to veneers is worth a read.
What happens at a bonding appointment?
Plan on 30 to 60 minutes per tooth. Dr. Ariyev picks a shade to match your tooth, lightly preps the surface so the resin grips, then builds it up in thin layers and shapes it by hand. Each layer is set with a light, then everything is trimmed and polished. Many people don’t need to be numbed at all. You can eat normally right after, though it’s smart to go easy on coffee and red wine for a day or two.
Who is bonding a good fit for?
Bonding works well if you have one or two teeth to fix, want a quick result, or aren’t ready to commit to veneers. It’s less of a fit if you want a big color change across many teeth, or if you grind heavily and won’t wear a night guard. Dr. Ariyev will be upfront if he thinks something else would serve you better.
Frequently asked questions
Does bonding damage the tooth?
Bonding usually needs little or no removal of natural enamel, which is a big part of why people like it.
Will insurance pay for bonding?
Bonding that repairs damage or decay is sometimes partly covered. Bonding done only for looks usually isn’t. We’ll check your plan before we start.
Does bonding look natural?
When it’s color-matched and polished well, it blends in closely with the teeth around it.
