If you have older fillings or dental crowns, you might occasionally wonder if they are still doing their job. Maybe you've noticed a dark shadow around a filling, slight sensitivity when drinking cold water, or perhaps you simply know your dental work is a few decades old.
While dental work is incredibly durable, it isn't always meant to last a lifetime. Every restoration has a shelf life, but that lifespan varies widely depending on your oral hygiene habits, lifestyle, and the specific materials used. So, how do you know if your dental work is genuinely failing or just aging gracefully?
In this blog, the team at Cherry Blossom Family Dentistry explains what we look for when advising our FishHawk patients on whether it’s time to replace their old restorations.
The Science of Aging Restorations: How Silver, Composite, and Crowns Actually Fail
Amalgam (Silver) Fillings: Material Expansion and Safety Realities
The amount and grade of mercury found in amalgam fillings have been deemed safe.
According to the American Dental Association, silver fillings (amalgam) do not need to be removed simply because they are older. If they are structurally intact, you should keep them unless you are sensitive to mercury or want white fillings for cosmetic reasons.
On average, amalgam fillings can last up to a decade or longer.
Composite (Tooth-Colored) Fillings: The Threat of Micro-Leakage
Micro-leakage refers to small gaps around restorations that allow bacteria and debris to penetrate and damage tooth enamel. If you have micro-leakage, it doesn’t necessarily mean you need a new composite filling. In some cases, your dentist can touch up the existing filling, provided the tooth is not damaged or decayed.
Tooth-colored fillings can last up to a decade or longer.
Dental Crowns: Margin Wear vs. Hidden Recurrent Decay
Your second-opinion dentist in FishHawk evaluates your restorations at every dental visit to ensure they are structurally sound. If we note margin wear (at the gumline) or new tooth decay, the dentist may recommend crown replacement.
According to the National Institutes of Health, margin wear and recurring decay are the primary reasons for tooth crown replacement.
The Cherry Blossom Code: How We Inspect Old Dental Work and Decide When to Replace It
Your dentist evaluates your dental work at every checkup and teeth cleaning. We explore breaches in the restoration material, general wear, and other telltale signs of crown and filling wear.
Your dentist will discuss findings with you and help you decide whether to replace the restoration immediately or wait and see. We’ll lay out the pros and cons so that you can make an informed decision.
