When you need a filling, your dentist may suggest a composite filling. But many patients ask the same question: Are composite fillings strong enough? The good news is — yes, they are! In this article, we’ll explore the strength, benefits, and reasons why composite fillings are trusted by dentists and loved by patients.
Whether it’s your first filling or a replacement, knowing the facts helps you feel more confident in the dental chair.
What Are Composite Fillings?
Composite fillings are tooth-coloured materials used to repair decayed, chipped, or broken teeth. They are made from a mixture of resin and fine glass particles, giving them strength and a natural look. These fillings blend in with your real teeth and are nearly invisible when you smile.
Compared to silver (amalgam) fillings, composites look better, feel lighter, and bond better to the tooth surface.
Are Composite Fillings Really Strong?
Yes, composite fillings are strong and durable, especially when used in small to medium-sized cavities. They can handle everyday tasks like chewing and biting with ease.
Here’s why they are strong:
- They bond tightly to your tooth: This helps the tooth stay stable and keeps it strong from the inside.
- They don’t need much drilling: Less tooth is removed, so more of your natural tooth remains. That keeps your tooth healthier.
- They hold up under pressure: Composite fillings are strong enough for front and back teeth. They last well under daily chewing forces.
With good care, they can last 5 to 10 years, or even longer.

Composite vs. Amalgam Fillings: A Quick Comparison
| Feature | Composite Fillings | Amalgam Fillings |
|---|---|---|
| Colour | Tooth-coloured | Silver/metallic |
| Material | Resin & glass | Metal alloy (with mercury) |
| Strength | Strong, flexible | Very strong, rigid |
| Aesthetic | Natural-looking | Noticeable when smiling |
| Tooth Preservation | Requires less drilling | Often needs more removal |
| Cost | Slightly higher | Usually cheaper |
| Bonding Ability | Bonds to tooth | Does not bond |
As you can see, while amalgam is very strong, composite fillings offer many more benefits — especially when it comes to appearance and tooth health.

Advantages of Composite Fillings
Composite fillings are a top choice for both dentists and patients for many reasons:
1. Natural Appearance
They match your real teeth. No one will even know you’ve had a filling.
2. Tooth-Friendly
Less healthy tooth is removed, which helps keep your tooth strong and long-lasting.
3. Safe and Mercury-Free
Composite fillings are free from mercury, unlike silver fillings. This makes them a safer option for many people.
4. Less Sensitivity
They don’t expand or shrink with hot or cold foods, so you feel less discomfort.
5. Easy Repairs
If a composite filling chips or cracks, your dentist can easily fix it without removing the whole thing.

How Long Do Composite Fillings Last?
On average, composite fillings last 5 to 10 years. Some even last longer with proper care.
To make your fillings last:
- Brush twice a day
- Floss daily
- Avoid biting hard items like ice or pen caps
- Visit your dentist every 6 months
With a good routine, your composite fillings can stay strong for many years.
Are They Suitable for Everyone?
Most people can safely get composite fillings. They work well for:
- Small and medium cavities
- Chipped or broken teeth
- Front or back teeth
However, if you grind your teeth at night or have very large cavities, your dentist may suggest other options. Always ask what’s best for your smile.

Any Disadvantages?
While composite fillings are great, they do have a few downsides:
- They may wear faster if you grind your teeth
- They can be more expensive than silver fillings
- They might stain over time from tea, coffee, or red wine
Even so, many people feel the benefits outweigh the small drawbacks.

Frequently Asked Question
Can composite fillings break?
Yes, but rarely. Like any dental material, they can chip or crack if you bite something hard. If this happens, your dentist can easily repair the filling without replacing the entire thing.
Do composite fillings hurt?
No. Dentists use local anaesthetic, so you won’t feel pain. You might feel some pressure during the procedure and slight sensitivity afterwards, but this goes away quickly.
Are composite fillings better than silver?
In many ways, yes. Composite fillings are more natural-looking, require less drilling, and bond directly to the tooth. Silver fillings may last longer in some cases but aren’t as visually pleasing.
Can I eat right after getting a composite filling?
Yes, composite fillings harden instantly with a special light. However, it’s a good idea to wait a couple of hours before eating hard or sticky foods.
How do I care for composite fillings?
Brush twice a day, floss regularly, and avoid very hard foods. Also, visit your dentist for check-ups every 6 months. With good care, your fillings can last up to 10 years or more.
