How Does a Dental Crown Protect a Tooth?

A Crown Shields the Tooth From Pressure

Every time you bite your teeth deal with pressure. A healthy tooth handles that pressure through its structure. A damaged tooth doesn’t have the same advantage especially if a large filling has replaced much of the original tooth.

A crown covers the tooth and gives it a stronger outer surface. So of leaving fragile areas exposed to normal biting forces the crown takes much of that pressure and spreads it across the restored tooth.

Cracks Are the Big Concern

Cracks deserve attention because they don’t always stay where they started. Pressure from chewing can make a crack spread through the tooth. Once it reaches deeper areas treatment becomes much more complicated.

A fitted crown holds the remaining tooth together and covers the damaged area. It doesn’t magically repair a crack that has already gone far though. Timing matters.

It Keeps Bacteria Away From Vulnerable Areas

A damaged tooth often has areas that’re easier for food and bacteria to reach. Decay can start around those spots especially when cleaning becomes difficult.

The crown creates a sealed covering around the prepared tooth. Your dentist also checks the fit around the gum line because a poor fit can leave space where bacteria and plaque collect.

After a Root Canal

Teeth that have had root canal treatment often need a crown when a significant amount of tooth structure has been lost. The inside of the tooth has been treated,. The remaining tooth still has to handle everyday chewing.

Think of it as protecting the structure thats left. The crown covers the tooth. Reduces the chance that normal biting forces will cause the weakened walls to break.

What a Crown Helps Prevent

A crown is mainly about stopping a tooth from becoming a bigger dental problem. Depending on why the crown was needed it can reduce the risk of damage to the remaining tooth structure.

• Cracking under chewing pressure especially when a large part of the original tooth is missing.

• More wear on a weakened tooth. The crown gives the exposed structure an outer surface.

• Food getting into areas although the crown still needs a good seal around its edges.

• A tooth breaking further after root canal treatment, which is one reason crowns are commonly used after structural loss.

• Further decay around an existing area. The crown helps protect the restored tooth. It doesn’t make brushing optional.

What Does This Feel Like in Life?

Once the crown settled in eating felt normal again. That boring feeling is actually the point. You stop thinking about the tooth.

Still there are limits. A crown protects the tooth. It doesn’t protect the surrounding gums from poor cleaning. And if you regularly bite hard objects grind your teeth at night or ignore a crown that feels loose you’re asking for trouble.

When Does a Tooth Need This Protection?

Dentists usually consider a crown when a tooth has lost structure that a regular filling won’t provide enough support. Large cavities can leave little healthy tooth behind. Cracks can weaken the walls. A tooth that has received root canal treatment may also need reinforcement when substantial structure has been removed.

The trick is getting the restoration for the actual condition of the tooth. Not every damaged tooth automatically needs a crown. Sometimes a filling or another restoration is enough.
