Dental Filling Materials: Which One Is Right for Your Cavity?
If your dentist has told you that you have a cavity, one of the first questions you will likely face is which filling material to choose. Patients in Sector 31, Gurugram often ask us this at The Tooth Atelier, and the honest answer is that it depends on where the cavity is, how large it is, your budget, and how much you care about the filling blending in with your natural teeth. This guide breaks down the four common filling materials so you can have a more informed conversation with your dentist.
Composite Resin Fillings
Composite resin is a tooth-colored material made of plastic and fine glass particles. It is the most commonly used filling material today because it bonds directly to the tooth and can match your natural shade closely.
- Appearance: Blends in well, almost invisible on front and back teeth.
- Durability: Good for small to medium cavities, typically lasts 5 to 10 years.
- Tooth preservation: Requires less removal of healthy tooth structure compared to some other materials.
- Best suited for: Visible teeth, moderate-sized cavities, and patients who want a natural look.
Amalgam Fillings
Amalgam, often called silver fillings, has been used in dentistry for over a century. It is a mix of metals including silver, mercury, tin, and copper.
- Appearance: Silver or grey colored, noticeable when you open your mouth wide.
- Durability: Very strong and long-lasting, often 10 to 15 years, sometimes longer.
- Cost: Generally one of the more economical options.
- Best suited for: Back molars that take heavy chewing load, where appearance is less of a concern.
Some patients prefer to avoid amalgam for cosmetic reasons or personal preference regarding mercury content, even though it is considered safe by major dental health bodies for most adults.
Ceramic Fillings (Inlays and Onlays)
Ceramic fillings, sometimes called porcelain fillings, are custom made in a lab or with digital scanning technology and then bonded to the tooth.
- Appearance: Excellent match to natural tooth color, resists staining over time.
- Durability: Very strong, often lasting 10 to 15 years or more.
- Cost: Usually the most expensive option due to lab fabrication and precision fitting.
- Best suited for: Larger cavities, cracked teeth needing more coverage, or patients wanting a long-term aesthetic solution.
Glass Ionomer Fillings
Glass ionomer is a tooth-colored material that releases fluoride, which can help protect against further decay in certain situations.
- Appearance: Tooth colored but less polished looking than composite or ceramic.
- Durability: Softer material, generally lasts a shorter time, around 3 to 5 years.
- Fluoride release: A helpful feature for patients prone to cavities.
- Best suited for: Small fillings in baby teeth, fillings near the gumline, or temporary restorations.
Comparing the Options at a Glance
| Material | Appearance | Typical Lifespan | Typical Range (INR) |
|---|---|---|---|
| Composite Resin | Tooth colored | 5 to 10 years | Rs 1,500 to Rs 4,500 per tooth |
| Amalgam | Silver/grey | 10 to 15 years | Rs 800 to Rs 2,500 per tooth |
| Ceramic | Tooth colored, stain resistant | 10 to 15+ years | Rs 6,000 to Rs 15,000 per tooth |
| Glass Ionomer | Tooth colored, less polished | 3 to 5 years | Rs 1,000 to Rs 3,000 per tooth |
These figures are a typical range only and actual costs depend on cavity size, tooth location, and the specific technique used. Your dentist at The Tooth Atelier will give you a clear estimate after examining the tooth.
How to Decide What Is Right for You
There is no single best filling material for everyone. A good decision usually factors in three things.
- Location of the cavity: Front teeth usually call for tooth-colored materials, while back teeth have more flexibility.
- Size of the cavity: Larger cavities may need the added strength of ceramic or amalgam.
- Budget and priorities: If aesthetics matter most, composite or ceramic are worth the investment. If durability on a budget is the priority, amalgam remains a reliable choice.
At The Tooth Atelier in Sector 31, Gurugram, we take time to explain these trade-offs clearly so you can make a choice that fits your tooth, your lifestyle, and your comfort level, rather than simply picking the most common option by default.

Frequently asked questions
Which filling material lasts the longest?
Ceramic and amalgam fillings tend to last the longest, often 10 to 15 years or more with good care. Composite resin typically lasts 5 to 10 years depending on the location and bite force on that tooth.
Are composite fillings as strong as amalgam?
Modern composite resins are quite strong for small to medium cavities, but amalgam still handles heavy chewing forces in back teeth slightly better over the long term. Your dentist can advise based on the cavity size and location.
Can I switch from an old amalgam filling to a tooth-colored one?
Yes, this is a common request. Your dentist at The Tooth Atelier can remove the old amalgam filling and replace it with composite or ceramic, provided the remaining tooth structure is healthy enough to support it.
Does insurance or cost vary a lot between materials?
Yes, cost varies by material and lab work involved. Amalgam and glass ionomer are usually the most economical, while ceramic fillings cost more due to custom fabrication. Ask our team for a treatment-specific estimate.
