A dental bridge replaces missing teeth but it creates a cleaning challenge underneath. Without the right care, decay can form on the supporting teeth and destroy your bridge. Here's how to clean it properly.

You chose a bridge to replace your missing teeth, and that was a great decision. But now you need to clean in a way you probably never had to before. The good news is it becomes second nature once you know what to do.

A bridge is fused to crowns on the teeth either side of the gap. The false tooth — called a pontic — sits in the space but doesn't attach to your gum. That means there's a gap underneath. Food and bacteria can get trapped there, and if you don't clean it, decay can form on the supporting teeth.

The supporting teeth have crowns on them, but the crown margin — the edge where the crown meets your tooth — is exactly where decay likes to start. Once decay gets under the crown, the whole bridge is at risk.

A standard toothbrush doesn't reach underneath a bridge. What you need is a tepe brush — a tiny interdental brush designed to slide under the pontic and scrub the surface. Your dentist or hygienist can show you the right size and how to use it.

Another excellent tool is a water flosser. This uses a stream of water to flush out food debris from under the bridge. Many people find it easier and more comfortable than interdental brushes. It's not a replacement for brushing, but it adds a layer of cleaning that makes a real difference.

Superfloss is another option. It's a special type of floss with a stiff end that threads under the bridge, allowing you to clean the surfaces of the supporting teeth.

Clean under your bridge at least once a day — ideally before bed. Use your interdental brush or water flosser to remove debris, then brush the surfaces of the supporting teeth as normal.

Don't skip the areas your bridge doesn't cover either. The teeth on either side of the bridge still need proper cleaning. And if you have other natural teeth, keep cleaning them as you always have.

The supporting teeth can develop decay at the margin of the crown. This often happens without pain at first, so you may not notice until the damage is serious. In severe cases, the decay weakens the tooth so much that the bridge cannot be saved and both supporting teeth need treatment.

Regular check-ups help catch problems early. Your dentist can check the margins of your bridge and spot any early signs of decay before they become serious.

A dental bridge can last many years — even decades — with the right care. The extra cleaning step takes just a few minutes a day and is the simplest way to protect your investment.
