When repairing damaged or decayed teeth, many dentists use tooth-coloured materials. But the difference between white fillings and composite bonding lies in how and why they’re applied.
What Are White Fillings?
To repair teeth affected by cavities, dentists often use white fillings. These are crafted from composite materials combining resin and tiny glass particles. The process involves clearing the decay, then applying the filling in layers that are hardened to match your tooth shape. The final result blends naturally and helps preserve the tooth’s integrity for years.
What Is Composite Bonding?
The purpose of composite bonding is to refine small flaws that affect your smile. It’s carried out using a pliable resin which hardens once shaped and polished. The process doesn’t require drilling and takes very little time. Because of its ability to improve tooth shape and color instantly, it’s ideal for front teeth.
Difference Between White Fillings and Composite Bonding
| Feature | White Fillings | Composite Bonding |
|---|---|---|
| Primary Purpose | Repair cavities and restore | Cosmetic enhancement, minor repairs |
| Material | Composite resin with glass fillers | Composite resin |
| Procedure | Decay removal, layering, curing | Surface application, sculpting, curing |
| Tooth Location | Back and front; withstands chewing forces | Front teeth or visible areas |
| Durability | Long-lasting (up to 10–15 years) | Durable but may need touch-ups every 5–10 years |
| Aesthetic | Matches natural teeth, less visible than amalgam | Highly aesthetic and customizable |
| Tooth Preparation | Requires cleaning decay | Minimal or no enamel removal |
| Cost | Generally more affordable | Can be more expensive, especially for multiple teeth |
Which One Should You Choose?
Choose a white filling if your tooth has decay or physical damage—it restores strength efficiently.
Composite bonding is your go-to for improving chipped or stained teeth.
Heavily used teeth, like molars, need the toughness of fillings.
Bonding fits front teeth best for aesthetic refinement.
