When you’re told you need a filling, your first thought might be how it’s going to look, especially if it’s a front tooth. Thankfully, modern dentistry offers tooth-coloured options that blend beautifully with your natural smile. But if you’ve ever heard your dentist mention GIC or composite fillings, you might wonder: what’s the difference, and which is right for you?
At Howick Dental Surgery, we’re all about helping our Howick community make informed decisions. Here’s a simple guide to GIC and composite fillings so you know what to expect at your next visit.
What is GIC?
GIC stands for Glass Ionomer Cement. It’s a tooth-coloured material that bonds chemically to the tooth surface and releases fluoride, which helps protect the tooth from further decay.
Benefits of GIC:
- Releases fluoride, helping to prevent cavities
- Bonds directly to the tooth, requiring minimal drilling
- Gentle on the tooth structure
- Often used for fillings near the gum line or in baby teeth
Limitations of GIC:
- Not as strong or wear-resistant as composite
- Less glossy and not quite as natural-looking for visible front teeth
In New Zealand, GIC is frequently chosen for patients who have high cavity risk or areas that don’t endure heavy chewing pressure.
What is Composite?
Composite resin is a tooth-coloured material made from a mixture of plastic and fine glass particles. It’s shaped and polished to match the natural look of your tooth.
Benefits of Composite:
- Excellent aesthetics — blends seamlessly with your natural tooth
- Durable enough for front and back teeth
- Allows for conservative removal of tooth structure
- Sets hard immediately under a curing light
Limitations of Composite:
- Slightly more technique-sensitive for the dentist
- Can stain over time if exposed to excessive coffee, tea, or smoking
- Usually a bit more expensive than GIC
So, Which Should You Choose?
It depends on your unique situation. At Howick Dental Surgery, we’ll consider factors like:
- Where the filling is located
- The size of the cavity
- Your bite and chewing pressure
- Your budget and aesthetic preferences
- Your risk of further decay
For small fillings in non-load-bearing areas, GIC might be ideal, particularly if fluoride protection is a priority. For highly visible teeth or areas that require strength and aesthetics, composite fillings are usually the go-to choice.
Both GIC and composite fillings are excellent options that can restore your smile beautifully. If you’re unsure which one is right for you, chat with the friendly team at Howick Dental Surgery. We’re here to help you make the best decision for your dental health — and your smile!
