Honestly, it depends on a few things, but when they're applied properly and looked after, most of my clients keep their gems for anywhere from 4 to 12 months. I've had clients come back for a refresh after nearly two years with their original gem still firmly in place.
Here's the real breakdown.
What actually determines how long a tooth gem lasts?
1. How it was applied
This is the big one. Tooth gems are bonded using dental-grade adhesive (the same kind that dentists use for braces). When the technique is right and the surface is properly prepared, the bond is genuinely strong.
A rushed application, skipping the prep steps, or using substandard products? That's when gems fall off after a week. This is why choosing someone who knows what they're doing matters more than the price.
2. Where it's placed
Gems on the front surface of your teeth, away from the biting edge, tend to last the longest. Placement close to the gum line or on a surface that gets a lot of friction can shorten the lifespan.
I always advise on the best placement for longevity during your appointment.
3. How you look after it
The composite is light-cured during your appointment, so it's already fully set by the time you leave. But the first 24-48 hours are still when you want to be a little more delicate than usual. Stick to softer foods, avoid anything too crunchy or chewy, and be gentle when brushing over your new gem.
After that, normal eating and drinking is completely fine. I've put together a full aftercare guide here if you want the complete rundown.
4. Your individual tooth surface
Everyone's teeth are slightly different. People who grind their teeth at night, or whose natural bite puts pressure on the gem placement area, may find gems don't last quite as long. I'll always be upfront with you if I think something might affect longevity.
What happens when a gem comes off?
Gems don't always come off completely. When they do fall off on their own, the tooth is usually fine, but sometimes a small amount of dental composite is left behind on the surface. This needs to be removed by a dentist or hygienist, not picked at yourself.
If you're booking in for a scale and polish, just let them know in advance that you have some dental composite that needs to be removed (it helps them come prepared). It's a straightforward thing for them to deal with.
I don't offer gem removal myself, and I'd be wary of any technician who does unless they're qualified to do so. There is a risk to your enamel if it's not handled properly.
If your gem comes off in the first couple of weeks, get in touch and I'll replace it. In my experience, early losses usually come down to aftercare in those first 48 hours.
Can I get it replaced?
Absolutely. Most clients come back every few months for a refresh, sometimes to replace a gem that's come off naturally, sometimes just to switch up the style. Once you're in my chair you'll probably want to try a different one anyway.
The honest answer
If you follow the aftercare, choose your placement well, and go to someone who applies them properly: expect 4-12 months, with plenty of clients going longer.
