Amalgam, Composite, Ceramic, or Glass Ionomer Filling: Which One Should You Choose?
When your dentist tells you that you need a filling, the next question is usually about material. Should you go with the traditional silver amalgam, a tooth-coloured composite, a durable ceramic, or an affordable glass ionomer? Each option has its own strengths, and the right choice depends on where the cavity is, your budget, and how much you care about appearance. This guide breaks down the differences so you can have an informed conversation with your dentist in Gurugram or Malviya Nagar, Delhi.
The Four Common Filling Materials
Most cavities today can be treated with one of these four materials, each suited to different situations.
Amalgam (Silver) Fillings
Amalgam is a mix of metals including silver, mercury, tin, and copper. It has been used in dentistry for well over a century and remains one of the strongest and most affordable options, particularly for back teeth that handle heavy chewing.
Composite (Tooth-Coloured) Fillings
Composite resin is a mix of plastic and fine glass particles that can be shaded to match your natural tooth colour. It bonds directly to the tooth structure and is the most commonly requested filling material today because of its natural appearance.
Ceramic (Porcelain) Fillings
Ceramic fillings, sometimes called inlays or onlays, are made in a lab or with a chairside milling machine and then bonded to the tooth. They offer excellent aesthetics and strength, making them a good choice for larger cavities where composite may not hold up as well.
Glass Ionomer Fillings
Glass ionomer is a tooth-coloured material that releases fluoride, which can help protect against further decay. It is softer than composite or ceramic, so it is generally used for smaller cavities, baby teeth, or areas that are not under heavy chewing pressure.
Comparing Durability, Aesthetics, and Cost
| Material | Durability | Aesthetics | Typical Range (INR) |
|---|---|---|---|
| Amalgam | 10 to 15 years, very strong | Silver colour, visible | 800 to 2,000 per tooth |
| Composite | 5 to 8 years | Matches tooth colour well | 1,500 to 4,500 per tooth |
| Ceramic | 10 to 15 years or more | Excellent, natural look | 6,000 to 15,000 per tooth |
| Glass Ionomer | 3 to 5 years | Slightly duller shade | 1,000 to 2,500 per tooth |
These are typical ranges seen across clinics in Gurugram and Malviya Nagar, Delhi. Your actual cost will depend on the size and location of the cavity, the number of teeth involved, and any additional preparation needed. Your dentist can give you an exact estimate after examination.
How to Choose the Right Filling for You
There is no single best material for everyone. Here is a simple way to think about it.
- Back teeth with heavy chewing load: Amalgam or ceramic tend to hold up better over time.
- Front teeth or visible areas: Composite or ceramic are the natural choice for appearance.
- Small cavities or baby teeth: Glass ionomer is often sufficient and budget-friendly.
- Large cavities needing extra strength and looks: Ceramic inlays or onlays are worth considering despite the higher cost.
- Tight budget with a need for durability: Amalgam remains a reliable, affordable option for back teeth.
Other Factors Worth Considering
Beyond material, a few other things affect how long your filling lasts and how well it performs.
- Cavity size: Larger cavities may need ceramic or amalgam rather than composite, since bigger fillings put more stress on the material.
- Bite pressure: If you grind your teeth at night, your dentist may recommend a stronger material regardless of your aesthetic preference.
- Oral hygiene: Any filling material lasts longer with regular brushing, flossing, and dental check-ups.
- Number of visits: Amalgam, composite, and glass ionomer are usually placed in a single visit, while ceramic inlays sometimes require two visits if made in a lab.
The best approach is to discuss your specific cavity, budget, and priorities with your dentist. A short consultation and X-ray can help determine which material offers the right balance of strength, appearance, and value for your situation. Patients visiting our clinic in Sector 47, Gurugram, or our Malviya Nagar location often ask to compare two or three options side by side before deciding, which is a reasonable approach for anything beyond a very small cavity.

Frequently asked questions
Which filling lasts the longest?
Amalgam and ceramic fillings generally last the longest, often 10 to 15 years or more with good oral hygiene. Composite fillings typically last 5 to 8 years, while glass ionomer fillings have the shortest lifespan, usually 3 to 5 years.
Are silver amalgam fillings safe?
Yes, amalgam fillings are considered safe by major dental health bodies for most adults. They have been used for over a century. However, many patients now prefer tooth-coloured options for appearance reasons, not safety concerns.
Can I switch my old amalgam filling to a white filling?
Yes, this is a common request. Your dentist will remove the old filling and replace it with composite or ceramic, depending on the size of the cavity and your budget. This is usually a straightforward procedure done in one visit.
Which filling is best for front teeth?
Composite or ceramic fillings are best for front teeth since they match your natural tooth colour closely. Amalgam is silver-coloured and glass ionomer tends to look duller, so both are usually avoided for visible teeth.
