When a tooth gets a cavity or damage, a filling helps restore its function and appearance. At a polyclinic in Dubai, composite fillings are a popular choice because they match the colour of natural teeth. But with different types of composite materials available, many people ask, “Which composite filling is best?”
In this guide, we will explore the different types of composite fillings, their benefits, and how to choose the right one for your needs.
What Are Composite Fillings?
Composite fillings are tooth-coloured fillings made from resin and glass particles. They blend well with natural teeth, making them a great choice for people who want a seamless smile.
Unlike silver amalgam fillings, composite fillings do not contain mercury and require less drilling. They also bond directly to the tooth, providing extra support.
Types of Composite Fillings
There are different types of composite fillings, each designed for specific uses. The best choice depends on the location of the tooth, the amount of pressure it will handle, and personal preferences.
1. Nanocomposite Fillings
Best for: Front teeth and small fillings
Nanocomposites contain tiny glass particles that make the material smooth and highly polishable. These fillings give a natural shine and are great for visible teeth. They also resist staining better than other types.
However, they may not be as strong as other composites for back teeth, which handle more pressure when chewing.
2. Microfilled Composite Fillings
Best for: Small cavities and cosmetic improvements
Microfilled composites have smaller filler particles, making them smooth and easy to polish. They provide an excellent aesthetic result and work well for minor repairs or filling front teeth.
However, they are not as strong as other composites, so they may not be suitable for large cavities or molars.

3. Hybrid Composite Fillings
Best for: Moderate-sized cavities and back teeth
Hybrid composites combine small and large filler particles, making them stronger than microfilled composites while still maintaining a good polish. They are often used for both front and back teeth.
These fillings offer a balance between strength and aesthetics, making them a common choice for many patients.
4. Microhybrid Composite Fillings
Best for: Large cavities and back teeth
Microhybrid composites contain a mix of small and medium-sized particles, making them highly durable. They are strong enough to handle chewing pressure and are ideal for molars and premolars.
However, they may not have the same level of shine as nanocomposite or microfilled fillings.
5. Bulk-Fill Composite Fillings
Best for: Deep cavities and faster treatment
Bulk-fill composites are designed for large or deep cavities. They allow dentists to place the filling in one layer, reducing the time needed for treatment.
These fillings are very durable, but they may not offer the best polish compared to other composite types.
Advantages of Composite Fillings
Composite fillings are a popular choice for many reasons:
- Tooth-Coloured Appearance – Blends naturally with teeth
- Less Drilling Required – Bonds directly to the tooth
- Mercury-Free – A safer alternative to silver fillings
- Supports the Tooth Structure – Reduces the risk of cracks
- Versatile Use – Can repair chips, gaps, and cavities
How Long Do Composite Fillings Last?
The lifespan of a composite filling depends on its type and location. On average, composite fillings last 5 to 10 years with proper care.
Here’s how long different types of composite fillings typically last:
| Type of Composite Filling | Average Lifespan |
|---|---|
| Nanocomposite | 5-7 years |
| Microfilled | 5-7 years |
| Hybrid | 7-10 years |
| Microhybrid | 8-12 years |
| Bulk-Fill | 10+ years |
To extend the life of your filling:
- Brush and floss daily
- Avoid biting on hard objects
- Visit the dentist for regular check-ups

Which Composite Filling Is Best for You?
The best composite filling depends on where the cavity is located and how much pressure the tooth will handle.
- For front teeth → Nanocomposite or Microfilled (best aesthetics)
- For small fillings → Microfilled or Hybrid (smooth polish)
- For back teeth → Microhybrid or Hybrid (more strength)
- For deep cavities → Bulk-Fill (fast and durable)
A dentist can recommend the best option based on your needs and oral health.
Are There Any Risks with Composite Fillings?
Composite fillings are safe, but some patients may experience:
- Tooth Sensitivity – Some people feel slight discomfort after getting a filling, but this usually goes away in a few days.
- Wear and Tear – Composite fillings may wear down over time, especially on back teeth.
- Staining – Dark-coloured foods and drinks (coffee, tea, red wine) can stain composite fillings.
If you experience pain or discomfort, see your dentist for an evaluation.

Final Thoughts
Composite fillings are an excellent choice for restoring teeth because they look natural and provide strong support.
The best composite filling depends on your tooth location, cavity size, and durability needs. If you’re unsure which filling is best for you, a dentist can guide you to the right option.
By maintaining good oral hygiene and visiting your dentist regularly, your composite fillings can last for many years, keeping your smile healthy and bright.
FAQs About Composite Fillings
Can composite fillings be used for all teeth?
Yes, composite fillings can be used on both front and back teeth. However, different types of composite materials are better suited for different teeth. Nanocomposite and microfilled are ideal for front teeth, while microhybrid and bulk-fill composites are better for molars.
Do composite fillings stain over time?
Yes, composite fillings can stain if frequently exposed to coffee, tea, red wine, and tobacco. Using a straw for drinks, rinsing with water after consuming staining foods, and maintaining good oral hygiene can help prevent discolouration.
Are composite fillings stronger than silver fillings?
Modern composite fillings are very durable and bond directly to the tooth, providing extra support. While silver (amalgam) fillings may last longer, composites offer a natural appearance and require less drilling, preserving more of the original tooth structure.
How soon can I eat after getting a composite filling?
You can eat as soon as the numbness wears off, usually within a few hours. However, it’s best to avoid hard or sticky foods for the first 24 hours to allow the filling to fully set.
Can I replace my old silver fillings with composite fillings?
Yes, many people choose to replace old silver fillings with tooth-coloured composites for a more natural look. However, replacement should only be done when necessary, as removing a filling may weaken the tooth. Your dentist can advise the best option.
