How long do those tooth-colored fillings actually last?

But I do wonder if it depends more on where the filling is and how big it is? Like, are front tooth fillings more likely to chip than ones in the back?

Honestly, I think you’re onto something with the location and size. I had a composite put in one of my front teeth after chipping it on a beer bottle (don’t judge, it was college). It looked great at first, but it chipped again after maybe two years, just from biting into an apple. My dentist said front teeth composites can be more prone to chipping, especially if you bite straight down on hard stuff. Molars seem sturdier, probably because there’s more tooth to work with and less direct impact.

And yeah, I was definitely told to avoid sticky candies and even biting my nails (guilty). I still slip up sometimes and cringe when I hear that little “crack.” The cosmetic side matters to me too—when it chipped, it was super obvious and kinda embarrassing until I got it fixed. I’d say if you care about aesthetics, be extra careful with those front ones. The tech is better now, but it’s not magic.

Yeah, that’s exactly what my dentist told me too. I was nervous about my front filling but it’s held up fine as long as I’m careful. Just try not to stress too much—being a little cautious really does help.

Mine’s been going strong for about 4 years now, and I’m not exactly gentle on my teeth (I love apples, probably more than I should). My dentist actually gave me a little checklist—like, avoid ice, don’t bite pens, that sort of thing. I figure, since I paid for it out of pocket, it’s worth babying the filling a bit. Have you ever had to get one replaced sooner than expected, or do most people find they last a decent while?

Four years is pretty solid, honestly. I see a lot of folks get 5-7 years, sometimes more, but it really depends on habits and luck. Apples are fine, but yeah, ice and pens are rough on fillings. I do get anxious about micro-cracks showing up early... sometimes you just can’t predict it.

Four years feels a bit on the short side to me, honestly. I’ve had composite fillings in my molars that are still holding up after almost eight years, and I’m not exactly gentle on them—lots of crunchy snacks, occasional forgetfulness about flossing... you get the idea. Maybe it’s partly down to the materials dentists use now? Some of the newer resin composites are supposed to be more durable than what was standard a decade ago.

I do agree, though, that habits make a huge difference. I used to chew ice all the time (bad idea, I know), and that’s when I noticed tiny chips or sensitivity popping up way sooner than expected. Once I stopped, things stabilized a lot. Pens are another story—I still catch myself doing that sometimes out of habit during long coding sessions.

The thing with micro-cracks is tricky. Sometimes you can’t even see them until they become a problem, and then it’s like... surprise, here’s another trip to the dentist. But from what I’ve read and experienced, most small cracks don’t instantly doom the filling unless there’s constant pressure or grinding happening.

I wonder if some folks just get unlucky with bite alignment or even how much force they use chewing without realizing it? My dentist showed me a 3D scan once where you could see uneven pressure points on my fillings—never would’ve guessed without the tech showing it.

Anyway, maybe it comes down to a mix of genetics, dental materials, and how much we push our teeth day-to-day. Apples seem safe enough in moderation (I eat them almost daily), but yeah... ice is brutal. If anyone’s worried about cracks, maybe ask your dentist about those digital scans—they’re pretty eye-opening and can help spot weak points before they turn into bigger issues.
