Amalgam Filling: Is It Safe and When Is It Used?

An amalgam filling is a long-lasting “silver” dental filling used mainly for back teeth. It’s made from a blend of metals, including mercury that binds the alloy into a strong material. Most health authorities consider amalgam safe for the general population, while some higher‑risk groups may be advised to choose alternatives.

What Is an Amalgam Filling?

Dental amalgam is a restorative material used to repair a tooth after decay has been removed. Because it resists wear and pressure, it is commonly used for molars and premolars where chewing forces are highest. The dentist shapes the material inside the prepared cavity and it hardens into a solid filling.

What Is Amalgam Made Of?

Amalgam is a metal alloy made by mixing liquid mercury with a powdered alloy of other metals. Typical ingredients include silver, tin, and copper, along with mercury to bind the mix. Once placed, the material sets and becomes firm, which is one reason it has a long clinical track record.

Why Dentists Still Use Amalgam

Amalgam remains a practical option in certain situations. It tolerates moisture better than some tooth‑colored materials during placement and can be faster to place in difficult-to-isolate cavities. In large cavities on back teeth, it can offer dependable longevity at a lower cost than many alternatives.

Safety and Mercury Concerns

The main debate around amalgam relates to mercury, which is part of the material. In a set filling, mercury is bound within the restoration, but small amounts of mercury vapor can be released, especially when the filling is placed or removed. Most patients do not experience health problems from amalgam, yet medical guidance can differ for certain groups.

What major health bodies say

Major dental and public health organizations generally state that dental amalgam is a safe and effective filling material for the general population. Some authorities also note that people with allergies to any amalgam components should avoid it. Guidance often emphasizes that removing an intact, well-functioning filling only to “get rid of mercury” is usually not recommended.

Who may be advised to consider alternatives

Some higher‑risk groups may be advised to use non‑amalgam materials whenever suitable. This may include people with known mercury or metal allergies and certain patients with specific health conditions, based on clinical judgment. Pregnant or nursing patients and children may also be offered alternatives depending on local guidance and availability.

Should you remove old amalgam fillings?

If an amalgam filling is intact, not leaking, and there is no decay underneath it, replacement is rarely urgent. Removing a filling can temporarily increase exposure to mercury vapor and may require taking away additional healthy tooth structure. Replacement is typically considered when the filling is cracked, worn, recurrent decay is present, or for a clear medical reason discussed with your dentist.

Amalgam vs Other Filling Types

Choosing a filling material is a balance between strength, appearance, tooth location, and budget. Amalgam is usually stronger than many tooth‑colored options in high‑load areas, but it is also more visible. Your dentist will weigh factors like cavity size, bite forces, and your aesthetic preferences.

• Composite (tooth‑colored): blends with natural teeth and is popular for visible areas, but can be more technique‑sensitive and may wear faster in large back‑tooth cavities.
• Ceramic/inlay restorations: offer excellent aesthetics and stain resistance, but they typically cost more and often require lab work.
• Glass ionomer: can release fluoride and is useful in specific cases, yet it is generally less durable under heavy chewing forces.

Advantages and Disadvantages

Advantages

• Durability: often performs well for years on back teeth under heavy chewing forces.
• Cost: tends to be more affordable than many tooth‑colored or lab-made restorations.
• Placement: can be less sensitive to minor moisture during placement in some clinical situations.

Disadvantages

• Appearance: the silver color is noticeable, so it’s rarely chosen for front teeth.
• Tooth preparation: it may require removing a little more tooth structure to create mechanical retention.
• Mercury concerns: while considered safe for most people, it may not be the best first choice for some higher‑risk patients.

What to Do After Getting an Amalgam Filling

Follow your dentist’s instructions for the first day after treatment. Avoid very hard foods on the treated side until the filling has fully set and your bite feels normal. If you notice a high spot, sharp edge, or pain when chewing, schedule a quick adjustment.

• Brush and floss normally, but be gentle around the area if your gums are sore.
• Avoid chewing ice or very hard foods that could crack any filling material.
• Tell your dentist if you grind your teeth; a night guard may protect restorations.

Cost of Amalgam Fillings

Pricing varies by country, clinic, and the size of the cavity (single‑surface, two‑surface, or three‑surface restorations). Extra needs—such as X‑rays, anesthesia, or treating deeper decay—can also change the total cost. Ask for a written estimate that lists the procedure, material, and any follow‑up visits.

Example: 2026 fee tariff in Turkey

In Türkiye, many clinics reference the Turkish Dental Association’s annual fee tariff as a baseline, though actual clinic fees may differ. In the 2026 tariff, VAT‑included fees for amalgam fillings are listed by surface: one‑surface 2,845 TL, two‑surface 3,805 TL, and three‑surface 4,845 TL. Your dentist can confirm which category your cavity fits and whether additional procedures are needed.
