Clinical review: Dr. Samreen Ejaz, BDS, RDS ·
Why we might choose it
Glass ionomer is a tooth-coloured dental cement. It’s made differently from composite, sets differently and has different strengths. It can be the final filling in a suitable spot, or part of a bigger repair. Two tooth-coloured materials can look much the same and still do quite different jobs, so we choose the one that fits the task.
What Dr. Samreen looks at
Where the cavity is, how much chewing force it takes, how much tooth is left and whether the area can be kept dry all affect the choice. She’ll explain why glass ionomer suits this particular tooth, and whether it’s meant to be the final filling or a stage before something else. A tooth that takes heavy biting or is badly broken may need a different material or design.
At the appointment
We examine and prepare the tooth, then place the glass ionomer and shape it. Depending on the product, the surface may need protecting while it first sets. We’ll give you eating and cleaning instructions for the exact product we used, so please follow those. Then we check your bite so the filling doesn’t take more pressure than it should.
Looking after it
Keep the area clean and tell us if you notice a piece missing, a rough patch or the sensitivity coming back. If this filling is one step in a longer plan, please come for the next appointment. After root canal treatment, a glass ionomer filling repairs the top part of the tooth. It’s separate from the filling that goes inside the root canals.
BEFORE YOUR APPOINTMENT
Questions about glass ionomer fillings
Is it just a temporary filling?
No, it can be either. Ask Dr. Samreen whether she means your filling to be short-term or the final one.
Why would you use composite instead?
Where the tooth is, how it needs to look, how much biting it takes and how well the area can be kept dry can all favour composite. The examination decides, not a fixed rule.
This is general information. What’s right for your tooth depends on what Dr. Samreen finds when she examines it.
