Key Takeaways
- Amalgam Fillings are Safe: Mercury in dental fillings is mixed with other metals. Research shows that it is safe for most adults and teenagers.
- Removal isn’t Necessary: Changing old silver fillings only because of mercury can let out more vapors than keeping them. You should only take them out if they are cracked, worn out, leaking, or have cavities.
- Modern Alternatives: There are types of fillings for teeth made of resin, or gold. These fillings don’t have mercury, and keep your teeth healthy.
People often worry about mercury in dental fillings, but most of the fears don’t match the actual science. The truth is more balanced. Amalgam fillings have been used safely for years, but today we also have healthier, more natural-looking choices. At Puri Dentistry, we help patients in Oxnard sort fact from fear so they can make the decision that feels right.
Why Everyone Talks About Mercury
If you’ve ever had a silver-colored filling, chances are it was made from amalgam, a mix of metals that includes mercury. That word, mercury, stops people in their tracks. We hear the same questions every week: “Isn’t that dangerous?” or “Should I have these taken out?”
It’s understandable. We’ve been told for years to avoid mercury in fish, thermometers, and even in certain household products. So the idea that it’s inside your mouth doesn’t sit well.
What the Research Actually Shows
Here’s the straight story. In amalgam, mercury isn’t floating around by itself. It’s combined with silver, tin, and copper to form a solid material. That bond makes it stable.
Yes, tiny amounts of mercury vapor can be released when chewing, but study after study shows the levels are far below what’s considered harmful. Groups like the FDA and the American Dental Association say amalgam is safe for most adults and teens over age six.
That said, some people are better off with alternatives. Pregnant women, patients with allergies to metals, or anyone who simply doesn’t feel comfortable with amalgam may want another option.
Why Patients Still Feel Uneasy
Science aside, emotions matter. If the idea of mercury makes you lose sleep, that’s a good enough reason to talk about replacements. We’ve had patients in Oxnard who’ve kept their silver fillings for decades without a problem, but just wanted peace of mind.
The important thing to know: ripping out every silver filling “just in case” isn’t always smart. Taking out a stable filling can release more vapor than leaving it in place. That’s why dentists only recommend removal if the filling is cracked, worn down, or leaking.
Modern Alternatives to Amalgam
Here’s where things get easier. Most new dental fillings today are done with composite resin, those tooth-colored materials that blend right in.
Why people like them:
- They look natural. No silver flashes when you laugh.
- They bond directly to the tooth, so we don’t drill away as much healthy structure.
- And, yes, no mercury at all.
There are other choices too, like porcelain or gold fillings. But composites are the most popular because they balance strength, cost, and appearance.
Insurance and Cost Questions
For years, amalgam was chosen because it was cheap and durable. Some insurance plans still prefer it. Composites can cost a little more, but many plans now cover them. And when you factor in how they look and how much patients prefer them, most people in Oxnard don’t hesitate.
At Puri Dentistry, we always lay out costs clearly so there are no surprises. We’ve even had patients switch just one filling at a time to spread out the expense.
When It Makes Sense to Replace
So, when should you change old dental fillings? Not because of the mercury alone. The real reasons are:
- Cracks in the filling
- Pain or sensitivity
- Decay under the filling
- Cosmetic reasons (wanting a natural look)
A patient story comes to mind. A man in his 60s came in with three silver fillings from the 80s. Two were holding up fine. One had a small fracture. We replaced that one with a composite, left the others alone, and he left feeling reassured without unnecessary work.
Clearing Up Myths We Hear All the Time
- “All mercury fillings are dangerous.” Not true. For most people, they’re stable and safe.
- “You have to replace every old filling.” No, you replace when there’s damage or a personal choice.
- “White fillings don’t last.” Modern composites are much stronger than they used to be, often lasting a decade or more with good care.
Prevention Is Still the Best Plan
No matter what kind of filling you have, avoiding new cavities is the real win. Daily brushing, flossing, and regular cleanings go a long way.
Living in Oxnard, we also talk with patients about diet. Beachside smoothies, sugary coffee runs, or even dried fruit from the farmers’ market can sneak in sugar that wears down enamel.
Final Takeaway
Mercury in dental fillings isn’t the hidden danger some headlines make it seem. The science shows amalgam is safe for most people.
At Puri Dentistry, we don’t believe in scare tactics. We believe in clear choices. If you have old silver fillings and you’re wondering what to do, we’ll check their condition, explain your options, and let you decide if, and when, you’d like a change.
Your smile is yours. The materials we use should make you feel safe, confident, and comfortable every time you bite, chew, or laugh.
