White vs. Silver Fillings: Composite or Amalgam?
Tooth-colored composite or traditional silver amalgam? Here’s an honest side-by-side of the two filling materials — and which tends to fit where.
The short answer
A composite (white) filling is a tooth-colored resin bonded directly into the tooth, so it blends in and lets the dentist keep more of your natural tooth. An amalgam (silver) filling is the traditional metal material — very durable and inexpensive, but silver-colored and not bonded to the tooth.
In short: composite looks natural, bonds to the tooth, and is the standard for visible teeth; amalgam is extremely hard-wearing and economical but shows as a dark spot and requires removing a little more tooth. Today most fillings are composite, with amalgam reserved for certain back-tooth situations.
Composite (White) Fillings vs. Amalgam (Silver) Fillings
| Comparison factor | Composite (White) Fillings | Amalgam (Silver) Fillings |
|---|---|---|
| Appearance | Tooth-colored — blends in, essentially invisible | Silver/gray — visible when you laugh or talk |
| How it attaches | Chemically bonded to the tooth | Held mechanically in a shaped cavity (not bonded) |
| Tooth structure removed | Less — more natural tooth is preserved | More — the cavity must be shaped to hold it |
| Durability | Very good; typically 7–10+ years with care | Excellent; often the longest-lasting, 10–15+ years |
| Best for | Front and visible teeth, small-to-moderate cavities | Large cavities in back teeth under heavy chewing force |
| Cost | Usually a bit more than amalgam | Typically the most economical option |
| Mercury content | None | Mercury bound in a stable alloy (considered safe by the ADA/FDA) |
| At Highmark | Our standard — we place tooth-colored composite | We can safely remove and replace old silver fillings |
Which is right for you?
When a white (composite) filling is usually the better choice
- The tooth shows when you smile or talk
- You want the most natural-looking result
- The cavity is small to moderate
- You’d rather preserve as much natural tooth as possible
When a silver (amalgam) filling may still make sense
- A large cavity in a back molar under heavy biting force
- Durability and lowest cost are the top priorities
- The area is hard to keep perfectly dry during placement (which composite needs)
- You already have one that’s intact — there’s usually no need to replace it just for looks
How we handle this at Highmark Dental
At Highmark, tooth-colored composite is our standard — it looks natural, bonds to the tooth, and keeps more of your own tooth intact. We’ll always tell you honestly when a tooth genuinely needs a filling versus when it can simply be watched.
If you have old silver fillings, there’s usually no need to replace a sound one just for appearance. When one is cracked, leaking, or failing, we can remove it safely and restore the tooth — Dr. Skiba will give you a straight answer on whether it needs attention yet.
Cost & insurance
The right treatment — and its cost — depends on what we find during your exam, so we’ll always explain your options and the fees clearly before we begin anything. We accept many dental insurance plans and file your claims as a courtesy; any benefit estimate is exactly that — an estimate, and you’re responsible for what your plan doesn’t cover. We also accept cash, check, and major credit cards, with flexible payment arrangements available. See our Insurance page for the plans we accept.
Frequently asked questions
Are white or silver fillings better?
For most teeth today, composite (white) is the better all-round choice — it looks natural, bonds to the tooth, and preserves more structure. Amalgam (silver) is still extremely durable and economical, which can suit a large cavity in a back tooth. The best choice depends on the tooth’s location, the size of the cavity, and your priorities.
Should I replace my old silver fillings with white ones?
Not just for looks. A silver filling that’s intact and sealing well can stay for years. We recommend replacing one only when it’s cracked, leaking, decayed underneath, or breaking down — at which point we’ll restore the tooth, usually with composite.
Are silver (amalgam) fillings safe?
Major health authorities including the ADA and FDA consider amalgam safe for adults and children over six; the mercury is bound in a stable alloy. That said, many patients simply prefer tooth-colored composite, and that’s what we place as our standard.
Do white fillings last as long as silver?
Modern composite fillings are strong and typically last 7–10 years or more with good care. Amalgam can last a bit longer on average, especially on heavy-chewing back teeth — but for most everyday fillings the difference is small, and composite’s appearance and conservatism usually win out.
Does getting a filling hurt?
The tooth is numbed with local anesthesia first, so the procedure itself is comfortable. Some mild cold sensitivity for a few days afterward is normal and settles. If you’re anxious, tell us — we take an unhurried, gentle approach.
