Composite vs Amalgam vs Glass Ionomer vs Ceramic Fillings: Which One Is Right for You?
If your dentist has told you that you need a filling, you may be wondering which material is best. There are four common types used today: composite, amalgam, glass ionomer, and ceramic. Each has its own strengths in durability, appearance, and cost. This guide explains the differences in plain language so you can have an informed conversation with your dentist at your next visit in Sector 39, Gurugram.
Why Filling Material Choice Matters
A filling repairs a cavity and stops decay from spreading further into the tooth. But not every filling suits every situation. Factors like the size and location of the cavity, how much chewing pressure the tooth handles, and your budget all play a role in choosing the right material.
Composite Fillings
Composite fillings are made of a tooth-coloured resin mixed with fine glass or quartz particles. They are the most commonly used filling today for visible teeth.
Pros
- Matches your natural tooth colour closely
- Bonds directly to the tooth, so less drilling is needed
- Suitable for small to medium cavities on front and back teeth
Cons
- Less durable than ceramic or amalgam for very large cavities
- Can wear down or stain slightly over the years
Amalgam Fillings
Amalgam is the traditional silver-coloured filling made from a mix of metals. It has been used for decades because of its strength.
Pros
- Very strong and durable, especially for back teeth that handle heavy chewing
- Generally more affordable than tooth-coloured options
- Resistant to further decay around the edges when properly placed
Cons
- Silver colour is visible and not cosmetically ideal
- Requires slightly more tooth structure to be removed for placement
Glass Ionomer Fillings
Glass ionomer fillings release fluoride, which can help protect the tooth from further decay. They are often used for children's teeth, small cavities, or as a temporary filling.
Pros
- Releases fluoride for added decay protection
- Gentle on the tooth, good for baby teeth or root surface cavities
Cons
- Less durable than composite or ceramic, usually lasting a shorter time
- Not strong enough for large cavities or heavy chewing areas
Ceramic Fillings
Ceramic fillings, often made of porcelain, are custom-made in a lab and bonded to the tooth. They are typically used for larger cavities or when a very natural appearance is important.
Pros
- Excellent aesthetics, closely mimics natural tooth enamel
- Highly durable and resistant to staining
Cons
- Usually the most expensive option
- May require two visits since it is often made outside the mouth
Comparing the Options
| Filling Type | Durability | Aesthetics | Typical Range (INR) |
|---|---|---|---|
| Composite | Moderate to good, 5-8 years | Very good, tooth-coloured | 1,500 to 4,500 per tooth |
| Amalgam | Very good, 10-15 years | Poor, silver-coloured | 800 to 2,500 per tooth |
| Glass Ionomer | Fair, 3-5 years | Moderate, close to tooth shade | 1,000 to 2,500 per tooth |
| Ceramic | Excellent, 10-15+ years | Excellent, natural look | 5,000 to 12,000 per tooth |
These are typical ranges seen at clinics around Sector 39, Gurugram, and actual costs depend on the size of the cavity, tooth location, and any additional treatment needed. Your dentist can confirm exact pricing after an examination.
How to Decide Which Filling Is Right for You
There is no single best filling for everyone. Here are a few points to consider:
- If the cavity is on a visible front tooth, composite or ceramic will look more natural.
- If the cavity is large and on a back molar that does heavy chewing, amalgam or ceramic may offer more strength.
- If budget is a bigger concern right now, amalgam or glass ionomer may be more affordable choices.
- If you want a long-term, highly durable and natural-looking solution, ceramic is often worth the extra investment.
Your dentist will also examine the depth and position of the cavity before recommending a material, since not every option works for every tooth. A short consultation and X-ray usually give enough information to suggest the most suitable filling for your specific case.

Frequently asked questions
Which filling lasts the longest?
Ceramic and amalgam fillings tend to last the longest, often 10 to 15 years or more with good oral care. Composite fillings usually last 5 to 8 years, and glass ionomer fillings have the shortest lifespan, typically 3 to 5 years.
Can I switch from amalgam to composite fillings?
Yes, old amalgam fillings can be replaced with composite or ceramic fillings during a routine visit, especially if they are worn, cracked, or you want a more natural look. Your dentist will check if replacement is truly needed first.
Are white fillings as strong as silver fillings?
Modern composite fillings are quite strong for small to medium cavities, especially in front teeth or lower-bite areas. For large cavities or heavy chewing surfaces, amalgam or ceramic may offer better long-term strength.
Does dental filling cost depend on the cavity size?
Yes, larger or deeper cavities usually cost more to fill because they need more material and time, regardless of which filling type you choose. Your dentist can give an estimate after examining the tooth.
