Composite Bonding Compared With Amalgam Fillings for Sensitive Teeth

Why Sensitivity Changes the Choice

Bonding is often the better fit when a tooth is sensitive and also needs a small repair. The material is tooth-coloured and bonds directly to the tooth. The dentist can usually preserve more of the natural structure around the damaged area.

Amalgam fillings work differently. They’re made from a metal-based mixture. Are packed into the prepared cavity. They’re tough. Have been used for decades but they don’t bond to the tooth in the same way composite does.

What Happens During Treatment?

With bonding the dentist prepares the area and applies the resin in layers. Each layer is hardened before the next one goes on. The final shape is adjusted so your bite feels normal.

Amalgam usually needs a mechanical approach because the material doesn’t bond directly to enamel and dentine. That can mean removing tooth structure to create enough space and shape for the filling to stay secure.

Does Composite Bonding Reduce Sensitivity?

It can particularly when sensitivity is coming from exposed or damaged tooth structure that needs sealing. Composite covers the area and creates a barrier between the tooth and whatever is causing that sharp reaction.

• Cold drinks become less of an event, which’s nice when you’ve stopped enjoying ice water.

• The tooth-coloured finish is an advantage especially if the sensitive tooth is visible when you smile.

• tooth removal is often possible with composite although the amount depends on how much damage is actually there.

• Amalgam still has a place for restorations where strength matters more than appearance and thats where I’d give it some credit.

Amalgam for a Sensitive Tooth?

If the cavity is small or moderate. The tooth can be restored conservatively composite bonding is my pick. It looks natural. Bonds to the tooth while preserving as much healthy structure, as practical.

Amalgam isn’t automatically wrong. For a damaged back tooth that takes serious chewing pressure its strength can make it a sensible option. Still sensitivity deserves an examination first because the filling material isn’t always the real culprit.
