Why consider cavity filling DIY?
Let’s face it: dental visits are expensive, often costing hundreds for a single filling. Students, young professionals, and busy adults often postpone care, only to see cavities worsen. A cavity filling DIY approach gives you temporary relief, restoring comfort and confidence without breaking the bank.
It’s not about replacing your dentist. Instead, it’s about having a reliable backup in emergencies when an appointment isn’t possible.
What tools are used for cavity filling?
Every dental procedure relies on precision tools. At home, you’ll need a smaller version of what’s found in a dentist’s office. Here are the essentials:
- Mirror and probe for inspection
- Scaler for removing debris
- Excavator for clearing cavity material
- Applicator for dental composite
- Burnisher for smoothing edges
- Curved tweezer for placing filler
