What is dental filling?
Dental filling are dental treatments used to repair teeth damaged by decay or injury. It involves removing the decayed portion of the tooth and filling it with a suitable material to restore its shape and function. The goal is to prevent further bacterial growth, restore dental function, and maintain oral health.
Why is dental filling needed?
1. Cavities: Cavities form when bacteria erode the tooth enamel.
2. Tooth damage: Cracks or breaks from accidents or biting hard objects.
3. Wear and tear: Over time, teeth may need repair due to wear.
The dental filling process:
Examination: The dentist examines the tooth to determine if a filling is needed.
Cleaning: The dentist removes the decay or damaged portion and cleans the tooth.
Filling: Filling material is placed into the cavity and shaped to match the tooth.
Polishing: The dentist checks the bite and polishes the filling for comfort.
Common filling materials:
Filling materials | Pros | Cons |
陶瓷 (Ceramic) | ✓ Best aesthetics, Tooth-colored material suitable for front teeth✓ Highly durable✓ Excellent biocompatibility, hypoallergenic | ✗ Higher cost✗ Less longevity compared to amalgam✗ May stain over time |
複合樹脂 (Composite Resin) | ✓ Natural appearance, customizable color✓ Strong bonding, less tooth removal | ✗ Not ideal for large cavities |
銀汞合金 (Amalgam) | ✓ Most cost-effective ✓ Good for large back tooth fillings | ✗ Metallic color, unaesthetic✗ Mercury content, though deemed safe✗ Requires more tooth removal |
玻璃離子 (Glass Ionomer) | ✓ Releases fluoride, prevents decay✓ Good for kids or gumline fillings✓ Lower cost | ✗ Weakest, wears quickly✗ Less aesthetic |
Care after dental filling:
Avoid hard foods: Avoid biting hard foods for a few days after treatment.
Maintain oral hygiene: Regular brushing and flossing to keep the filling clean.
Regular check-ups: Visit the dentist regularly to check the condition of the filling.
