Silver fillings are also called amalgam fillings. Dentists have used them for over 150 years. These fillings are made from a mix of metals. They include silver, mercury, tin, and copper. The result is a strong and long-lasting material that can repair tooth decay.
Why Are They Called Silver Fillings?
They are called silver fillings because of their color. However, they are not made from pure silver. The silver-colored appearance makes them easy to spot in the mouth. They are often used on back teeth where chewing happens the most.
Why Do Dentists Use Silver Fillings?
Dentists choose silver fillings for many reasons. They are strong, affordable, and easy to apply. They can last for many years, making them a trusted choice for restoring human teeth.
1. Durability
Silver fillings are very strong. They can handle the pressure from chewing and grinding. Some silver fillings can last 10 to 15 years or even longer. This makes them a good choice for molars, where people bite down the hardest.
2. Cost-Effective
Silver fillings are usually cheaper than other filling materials. For many people, this makes them a more affordable option. Dental insurance plans often cover silver fillings more easily than other materials like composite or ceramic.
3. Fast Application
The process of placing silver fillings is quick. Dentists can complete the procedure in just one visit. This saves time for both the patient and the dentist.
4. Proven History
Silver fillings have been used for more than a century. Their safety and effectiveness are well-documented. Many studies support their use in treating dental cavities.
What Are the Materials in Silver Fillings?
Silver fillings are made of dental amalgam. This is a mix of several metals:
- Mercury – Makes up about 50% of the mixture. It binds the other metals together.
- Silver – Adds strength and durability.
- Tin – Improves workability and helps the filling harden faster.
- Copper – Increases strength and reduces corrosion.
This mixture creates a strong and safe filling material when properly handled by a trained dentist.
Are Silver Fillings Safe?
Some people worry about mercury in silver fillings. But the mercury in amalgam is in a stable form. The American Dental Association (ADA), World Health Organization (WHO), and many other health agencies say silver fillings are safe for most people.
What About Mercury?
The mercury in silver fillings is not the same as toxic mercury from pollution. It is combined with other metals and does not remain in a free form. Only tiny amounts of vapor are released, and they are usually too low to harm a healthy person.
Who Should Avoid Silver Fillings?
In rare cases, some people may be sensitive to metals. Others may prefer metal-free options for personal or cosmetic reasons. Pregnant women and people with kidney disease may also choose other types of fillings, though research still supports the safety of silver fillings.
Advantages of Silver Fillings
There are many benefits to using silver fillings:
- Strong and long-lasting
- Less expensive than white fillings
- Easy to place during a single dental visit
- Resistant to wear and chewing pressure
Disadvantages of Silver Fillings
Silver fillings also have some downsides:
- They are not tooth-colored and are visible when you talk or smile.
- They may cause slight staining of the surrounding tooth over time.
- They can expand and contract with temperature changes, possibly causing small cracks in the tooth.
Are There Alternatives to Silver Fillings?
Yes. Dentists also use other filling materials, like:
- Composite resin – Tooth-colored and blends well with natural teeth.
- Glass ionomer – Releases fluoride but is less durable.
- Ceramic and porcelain – Very natural-looking but often more expensive.
- Gold fillings – Very durable and long-lasting but costly.
Each material has its pros and cons. Dentists will help you choose the right one based on your needs, location of the cavity, and budget.
How Are Silver Fillings Placed?
The dentist first numbs the area with local anesthesia. Then they remove the decay from the tooth. After cleaning the area, the dentist places the silver filling inside. They shape and polish it to fit your bite.
How Long Does It Take?
The entire process usually takes less than an hour. You can eat and drink after the numbness wears off. There may be some slight sensitivity for a few days, but it should go away quickly.
How Long Do Silver Fillings Last?
Silver fillings can last for 10 to 15 years or more. Good oral hygiene helps them last longer. You should brush twice a day, floss daily, and visit your dentist regularly. Avoid biting on very hard objects to protect your fillings and teeth.
Can Silver Fillings Be Replaced?
Yes. If a silver filling gets worn out or damaged, your dentist can remove it and place a new one. Some people also choose to replace silver fillings with tooth-colored ones for cosmetic reasons. Your dentist can guide you on the best option.
When Are Silver Fillings Recommended?
Silver fillings are a good option when:
- The cavity is on a back tooth (molar)
- You want a strong and long-lasting filling
- You want a more affordable treatment
- You don’t mind the filling being visible
When Are Other Fillings Better?
Tooth-colored fillings may be better when:
- The cavity is on a front tooth

Are Silver Fillings Still Used Today?
Yes. While many people now prefer white fillings for looks, silver fillings are still common. They remain a practical solution in many dental clinics. Dentists choose them based on function, cost, and the specific needs of the patient.
Do Silver Fillings Affect Your Health?
For most people, silver fillings are safe. They do not cause health problems in healthy individuals. Studies show that the small amount of mercury vapor from fillings is not enough to be harmful. If you have concerns, speak to your dentist.
Is There a Risk of Allergic Reactions?
Allergic reactions to silver fillings are very rare. But if you are allergic to mercury or other metals, tell your dentist. They can use a different filling material that is safe for you.

Taking care of silver fillings is simple. Follow these tips:
- Brush your teeth twice a day with fluoride toothpaste
- Floss daily to remove plaque
- Visit your dentist every six months
- Don’t chew on ice or hard candies
Will Silver Fillings Change Color?
Over time, silver fillings may become darker. This is normal and does not mean they are failing. If the color bothers you, you can discuss replacement options with your dentist.
Can Children Get Silver Fillings?
Yes. Silver fillings are often used in children because they are strong and less expensive. Pediatric dentists use them when the back teeth are affected. They can help protect the tooth until it naturally falls out or is replaced with a permanent tooth.
Is It Painful to Get Silver Fillings?
No. Dentists numb the area before working on the tooth. You should feel no pain during the procedure. Afterward, you might feel a little sore, but it goes away soon.
Can Silver Fillings Fall Out?
It’s rare, but silver fillings can fall out if they wear down or if the tooth breaks. If this happens, see your dentist right away. They will check the tooth and replace the filling if needed.
Should I Replace My Silver Fillings?
If your fillings are in good condition and you are not having problems, there is no need to replace them. However, if they are cracked, leaking, or you want a more natural look, your dentist may recommend replacing them with modern materials such as teeth bonding.
Do Silver Fillings Work with Other Treatments?
Yes. Silver fillings can be used with other dental treatments like teeth surgery, crowns, and root canals. Your dentist will make sure the materials work well together for your long-term dental health.
Conclusion
Silver fillings are a safe, strong, and cost-effective way to treat cavities. They are especially useful in back teeth where chewing force is high. While not as natural-looking as white fillings, they have a long history of success in dentistry. If you want the best teeth treatment for your case, talk to your dentist about the pros and cons of each filling material.
