If you’ve had dental work done years ago, chances are you might have some metal fillings—those silver or gray patches that were the go-to fix for cavities. While they’ve done their job, modern dentistry offers more natural-looking and durable options. One popular choice? Porcelain fillings.
But can you replace your old metal fillings with porcelain ones? And should you? Here’s everything you need to know before making that decision.
What Are Metal Fillings?
Metal fillings, also known as amalgam fillings, have been used for over a century. They’re made from a mix of metals, including silver, mercury, tin, and copper.
Pros of Metal Fillings
- Durable: They can last 10-15 years or more.
- Cost-effective: Generally cheaper than porcelain or composite options.
- Strong: Great for molars that handle a lot of chewing force.
Cons of Metal Fillings
- Noticeable: The dark color stands out against natural tooth enamel.
- Potential for cracking: Metal expands and contracts with temperature changes, which can cause tooth fractures over time.
- Mercury content: Though the ADA deems them safe, some patients are wary about mercury exposure.
Why People Are Switching to Porcelain Fillings
Porcelain fillings, or porcelain inlays/onlays, are custom-made to match the color of your natural teeth. They’re strong, long-lasting, and more aesthetically pleasing than metal.
Benefits of Porcelain Fillings
- Natural look: They blend seamlessly with your teeth.
- Stain-resistant: Porcelain resists discoloration better than resin-based composites.
- Biocompatible: No mercury or metal content.
- Protective: Often bonded to the tooth, making it more stable and less likely to fracture.
Can You Replace Metal Fillings with Porcelain?
Yes, you can replace your old metal fillings with porcelain, but it’s not always necessary. Here’s how to decide.
When Replacement Makes Sense
- Visible when you smile: If the filling is in a noticeable spot, porcelain is the more attractive choice.
- Cracks or leaks: Over time, metal fillings can pull away from the tooth, leading to decay.
- Tooth sensitivity: Expansion and contraction of metal can cause pain.
- Personal preference: Some patients simply prefer a metal-free mouth.
When It Might Not Be Needed
- Stable and secure: If your metal filling is in good shape and isn’t causing problems, there may be no urgent need to replace it.
- Deep fillings: In some cases, removing large metal fillings can risk damaging the tooth structure.
The Process of Replacing Metal Fillings
If you and your dentist decide replacement is the right move, here’s what to expect:
Step 1: Consultation and Assessment
Your dentist will evaluate the current state of your fillings using X-rays and a clinical exam. They’ll check for cracks, decay under the filling, or signs of wear.
Step 2: Removal of Old Filling
The dentist carefully removes the metal filling. If there’s decay beneath it, that will be cleaned out as well.
Step 3: Tooth Preparation
The cavity is shaped and smoothed to prepare it for the porcelain inlay or onlay.
Step 4: Impression and Temporary Filling
A mold of your tooth is taken to create a custom porcelain piece. A temporary filling is placed while the lab makes the permanent one.
Step 5: Final Placement
At your next appointment, the temporary filling is removed, and the porcelain restoration is bonded in place.
Are There Risks to Replacing Metal Fillings?
Any dental procedure carries some risk, though replacing a filling is routine. Some things to consider:
- Tooth sensitivity: Some patients experience short-term sensitivity after replacement.
- Damage to tooth structure: In rare cases, removing a large filling can compromise the tooth. Your dentist may recommend a crown instead.
- Cost: Porcelain is more expensive than metal or composite fillings, especially if not covered by insurance.
How Long Do Porcelain Fillings Last?
With proper care, porcelain fillings can last 10-15 years or more. They’re highly durable and resistant to wear, making them a strong investment.
To get the most life out of them:
- Brush and floss daily
- Avoid chewing on hard objects.
- Visit your dentist regularly for checkups and cleanings.
Alternatives to Porcelain Fillings
If porcelain is out of your budget or not the right fit, there are other tooth-colored options available:
Composite Resin
- Pros: More affordable than porcelain, natural appearance.
- Cons: Not as durable, can stain over time.
Gold Fillings
- Pros: Extremely durable, can last over 20 years.
- Cons: Very noticeable and often more expensive than porcelain.
