Tooth Filling Materials Compared: Amalgam, Composite, Glass Ionomer, and Ceramic
If you have a cavity, your dentist will usually offer more than one filling material to fix it. Each option has its own strengths when it comes to durability, appearance, and cost. Understanding the basics can help you have a more informed conversation with your dentist before treatment.
Why Filling Material Choice Matters
Not every filling material suits every tooth or every patient. Factors like the size and location of the cavity, how much biting force the tooth takes, your budget, and how important the appearance is to you all play a role. Below is a straightforward comparison of the four common options used in dental clinics across Gurugram.
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.
- Strength: Very durable, handles heavy chewing forces well
- Appearance: Silver or dark grey colour, visible when you smile or open your mouth
- Best for: Back teeth (molars) where chewing force is high and appearance matters less
- Longevity: Often 10 to 15 years or longer
Amalgam is generally the most economical option and requires less time in the chair since it sets quickly.
Composite Resin (Tooth Coloured Fillings)
Composite resin is a plastic and glass mixture that is shade matched to your natural tooth colour.
- Strength: Good for small to medium cavities, less ideal for very large fillings under heavy chewing load
- Appearance: Blends in naturally, the most popular choice for front teeth
- Best for: Front teeth, visible areas, and patients who prefer a natural look anywhere in the mouth
- Longevity: Typically 5 to 10 years, depends on cavity size and bite habits
Composite bonds directly to the tooth structure, which means less healthy tooth needs to be removed compared to amalgam.
Glass Ionomer
Glass ionomer cement is a tooth coloured material that releases fluoride over time, which can help protect against further decay.
- Strength: Softer than composite or amalgam, not ideal for high pressure areas
- Appearance: Tooth coloured but less polished looking than composite
- Best for: Small cavities near the gum line, baby teeth, or as a temporary filling
- Longevity: Usually 5 years or less
Its fluoride release makes it a useful choice for patients who are more prone to cavities, especially children.
Ceramic (Porcelain) Fillings
Ceramic fillings, sometimes placed as inlays or onlays, are made in a lab or with in-office milling technology and bonded to the tooth.
- Strength: Very durable and resistant to staining
- Appearance: Excellent match to natural tooth colour and shine
- Best for: Larger cavities where strength and looks both matter
- Longevity: Often 10 to 15 years or more
Ceramic usually costs more than the other options and may need two visits, but many patients find the durability and appearance worth it.
Quick Comparison
| Material | Durability | Appearance | Typical Range (per tooth) |
|---|---|---|---|
| Amalgam | High | Silver, visible | Rs 800 to Rs 2,000 |
| Composite Resin | Moderate to High | Tooth coloured | Rs 1,500 to Rs 4,000 |
| Glass Ionomer | Low to Moderate | Tooth coloured, less polished | Rs 800 to Rs 2,500 |
| Ceramic | High | Best natural match | Rs 5,000 to Rs 15,000 |
These are typical ranges seen at dental clinics in Gurugram and can vary based on the size of the cavity, the tooth involved, and the technique used. Your dentist can give you an accurate estimate after examining the tooth.
How to Decide
Think about where the cavity is, how visible it will be when you smile or talk, and how much you are willing to spend. Front teeth usually call for tooth coloured options like composite or ceramic. Back teeth with heavy chewing loads can often manage well with amalgam, composite, or ceramic depending on the size of the cavity. Glass ionomer works well for small cavities, gum line areas, or in children's teeth.
The right choice is not always the most expensive one. It is the one that fits your specific tooth, your bite, and your priorities. A short consultation at our Gurugram clinic can help you weigh these options clearly before your filling appointment. Call us at +91 79482 24075 to book a visit.
Frequently asked questions
Which filling material lasts the longest?

Are silver amalgam fillings safe?

Can I switch my old amalgam filling to a tooth coloured one?

Does insurance or cost differ much between materials?
Yes, amalgam and glass ionomer are usually the most economical, while composite and ceramic cost more due to material and technique. Ask our team for a treatment estimate specific to your cavity size and location.
