Are Your Old Silver Fillings Still the Best Option?
For decades, silver (amalgam) fillings were the standard way to repair cavities. Millions of people still have them today, and many have served well for years.
But dentistry has changed.
Today, many patients visiting Dentalife in Calgary Downtown are asking whether they should keep their old amalgam fillings or replace them with modern white fillings.
Some are concerned about how the silver fillings look every time they smile.
Others have heard questions about mercury and wonder whether amalgam fillings are still safe.
And many simply want a more natural-looking smile.
At Dentalife, Dr. Curtis Westersund and Dr. Connor Westersund believe every patient deserves honest information and personalized recommendations. Rather than replacing fillings simply because they are old, they evaluate each tooth carefully and recommend treatment based on your oral health, your goals, and what is best for you.
What Are Amalgam Fillings?
Amalgam fillings have been used for more than 150 years.
They are made from a mixture of metals, including silver, tin, copper, and elemental mercury. Mercury binds these metals together into a durable material that has been widely used to restore back teeth.
Health authorities continue to state that dental amalgam is considered safe for most people. However, because amalgam contains mercury, some patients prefer to avoid placing new amalgam fillings or choose to replace older ones as part of a more health-focused approach.
For many people, the decision isn’t based on fear.
It’s based on preference.
They simply feel more comfortable choosing modern materials that are mercury-free and tooth coloured.
The Problems with Old Silver Fillings
While many amalgam fillings continue to function well, they can present challenges over time.
They Don’t Look Natural
Perhaps the biggest complaint is cosmetic.
Silver fillings are immediately noticeable whenever you laugh, smile, or open your mouth.
Even healthy teeth can appear darker because the metal shows through the enamel.
Many patients are surprised by how much brighter and more youthful their smile looks after replacing visible amalgam fillings with white composite restorations.
Teeth Can Become Weaker
Unlike modern bonded white fillings, amalgam fillings do not chemically bond to the tooth.
To keep them in place, more healthy tooth structure often had to be removed when they were originally placed.
As years pass, teeth containing large amalgam fillings may become more vulnerable to cracks or fractures, especially as chewing forces continue day after day.
They Expand and Contract
Metal responds to changes in temperature.
Hot coffee.
Cold drinks.
Ice cream.
Over time, repeated expansion and contraction may place stress on the surrounding tooth structure.
In some cases, this can contribute to cracks or leakage around the filling.
Concerns About Mercury
One of the most common questions we hear is:
“Are mercury fillings toxic?”
Scientific organizations continue to support the safety of dental amalgam for most patients. However, amalgam does release very small amounts of mercury vapour over time, particularly during chewing.
While these levels are generally considered below established safety limits, some patients prefer not to have mercury-containing materials in their mouths.
At Dentalife, we respect those personal preferences.
If replacing amalgam fillings is appropriate, we discuss your options and perform treatment thoughtfully and carefully.
The Benefits of White Fillings
Modern composite resin fillings have transformed restorative dentistry.
Today’s materials are strong, durable, and beautifully natural.
Some of the advantages include:
A Natural Appearance
White fillings are colour matched to your natural teeth.
Most people won’t even notice they’re there.
Instead of seeing dark metal every time you smile, you’ll see healthy-looking teeth.
More Conservative Treatment
Composite fillings bond directly to the tooth.
Because of this, dentists can often preserve more healthy tooth structure compared to traditional amalgam techniques.
Preserving natural tooth structure is one of the guiding principles of modern dentistry.
Strength and Support
Because composite bonds directly to the tooth, it can help reinforce the remaining tooth structure.
This may reduce the likelihood of future fractures in appropriate situations.
Mercury-Free
White composite fillings contain no mercury.
For patients who prefer mercury-free restorative materials, composite provides an excellent alternative.
Comfortable and Versatile
White fillings can repair:
- New cavities
- Chipped teeth
- Small fractures
- Worn teeth
- Minor cosmetic imperfections
This makes them useful for both restorative and cosmetic dentistry.
Dentalife’s Health-Focused Approach to White Fillings
At Dentalife, replacing a filling is never simply about changing its colour.
Our approach begins by asking a bigger question:
“What is healthiest for this tooth over the long term?”
Dr. Curtis Westersund and Dr. Connor Westersund evaluate several factors before recommending treatment, including:
- The condition of the existing filling
- Signs of leakage or decay
- Cracks in the tooth
- Bite forces
- Overall tooth strength
- Your oral health goals
- Your comfort and preferences
If a silver filling is functioning well and the surrounding tooth is healthy, replacement may not be necessary.
If a filling is failing, leaking, cracked, or affecting the strength or appearance of the tooth, replacing it with a modern white filling may be an excellent solution.
This personalized, health-focused philosophy ensures that every recommendation is based on what is best for you—not simply on replacing old dentistry.
Imagine Smiling Without Thinking About Your Fillings
One of the most rewarding parts of replacing old amalgam fillings is hearing patients say:
“I forgot those silver fillings were even there.”
Except now…
They’re gone.
Patients often describe feeling:
- More confident smiling
- Less self-conscious in photos
- Happier with the appearance of their teeth
- More comfortable knowing they have modern restorative materials
- Proud of investing in their long-term oral health
Sometimes the biggest transformation isn’t dramatic.
It’s simply the feeling of no longer worrying about what people see when you smile.
