What Is Composite Bonding?

Composite bonding uses a tooth-coloured resin that’s shaped directly onto the tooth. Your dentist bonds the material to the surface, adjusts the shape, then hardens it with a special light.

It’s especially useful when the goal is to improve the look of a tooth as well as repair minor damage. A small chip. A worn edge. A gap that bothers you when you smile.

Why People Like Bonding

• Tooth-coloured and subtle, which is a big deal if the tooth shows when you smile.

• Usually less tooth preparation is needed, so the dentist can preserve more of the natural tooth.

• Quick appointment in many straightforward cases, though larger repairs take more time and shaping.

What Is an Amalgam Filling?

Amalgam is the familiar silver-coloured filling material that has been used for decades. It’s made from a mixture of metals and is mainly used to repair teeth damaged by decay.

But there’s a catch if appearance matters to you. The silver colour stands out against natural enamel. Personally, that’s the part I like least about amalgam. A filling can do its job perfectly and still look like a filling.

Bonding or Amalgam for a Cavity?

This depends on the tooth and how much damage is present. Composite is often chosen when a natural-looking result matters, while amalgam has traditionally been used where durability under chewing pressure is the main concern.

And modern dentistry has moved far beyond the idea that every filling needs to be silver. Tooth-coloured composite is now a common choice for many cavities, although your dentist still needs to consider the size and position of the repair.

Which One Feels More Natural?

Amalgam is noticeable because of its colour. Composite is designed to disappear into the tooth, although it can stain or wear over time, especially if the repaired area gets a lot of use.

That’s a pretty good sign that the material is doing what he wanted it to do.

So, Which One Should You Have?

• A tiny cosmetic repair? Composite makes far more sense visually.

• A deep cavity in a molar needs a proper assessment, because appearance isn’t the only thing that matters there.

The material isn’t really the whole story. The condition of your tooth decides a lot more than the name on the filling tray.
