If you’ve ever wondered whether that crown or filling is going to outlast your car, your mortgage, or your kids living at home, you’re not alone. It’s one of the most common questions we get, so let’s dive into the answers.
How long does dental treatment actually last?:
Fillings: longer than you might think
The lifespan of a filling depends largely on the material. Composite (tooth-colored) fillings typically last somewhere between 7 and 10 years, though many last longer with consistent care. Amalgam (silver) fillings have historically lasted 10 to 15 years or more.
What shortens a filling’s life? Grinding your teeth is a big one. So is location: back teeth take more force and wear faster. A strong at-home routine makes a measurable difference too.
Something worth knowing: fillings don’t usually fail dramatically. They wear gradually, and your dentist can typically spot the signs before you ever feel anything. That’s one reason why keeping up with regular exams actually saves money over time.
Crowns: a solid investment when cared for
A well-placed crown with good home care can last 15 years or more, and plenty of them make it to 25 or 30. The variables are similar to fillings: grinding habits, biting patterns, and oral hygiene all play a role.
One thing people sometimes don’t realize: even though a crown covers the tooth, the tooth underneath still needs care. Decay can still form at the margin, the edge where the crown meets the gumline. Brushing carefully along that edge and flossing daily still matters, even with a crown.
The single biggest factor in how long your restorations last? What you do at home every day.
Implants: the closest thing to permanent
Dental implants are the longest-lasting restorative option we have. The implant itself, the titanium post that fuses with your jawbone, can last a lifetime with proper care. The crown that attaches to the top typically lasts 10 to 15 years before it may need to be replaced, depending on wear.
Implants require adequate bone density and healthy gums, which is why not everyone is an immediate candidate. But for those who qualify, they’re often the most cost-effective long-term solution. You’re not replacing the entire structure over and over, just the visible part when needed.
What actually makes these last
You’ve probably noticed a theme: the variables are largely the same across everything. Grinding, hygiene, and how consistently you come in for checkups are the biggest factors in whether a restoration reaches the high end of its lifespan or the low end.
If you have a crown, filling, or implant and you’re not sure how it’s holding up, your next cleaning is the perfect time to ask. We’re always happy to give you an honest assessment of where things stand.
