What’s Wrong with Refilling a Tooth with a Large Filling That Needs Replacement?

Fillings are a normal part of life for many people. Sometimes, there are genetic problems that cause teeth to become weak; other times, dietary factors weaken tooth enamel. In any case, decay does happen, and when a dentist is able to fill the void in the tooth with a filling, everything works. However, fillings are often temporary. They might become dislodged over time, but in many instances, the decay can worsen and cause the initial hole to grow bigger.

In the latter circumstance, a crown is usually a better option than another filling. Why? Let’s take a look!

1. Bacteria Erodes Tooth Enamel

You might already know this if you’ve had a cavity filled, but if you’re wondering why an existing cavity can’t simply be filled again, you might have excessive decay that’s eaten away at the portion of the tooth that was remaining.

When too much enamel is gone, the tooth can no longer hold the filling substance in place. When this happens, your dentist will clear away the decayed portion of the tooth and leave the healthy part, which will serve as a foundation for a crown. The crown is then shaped and colored so it looks just like your natural teeth, but it won’t be susceptible to the decay and damage your tooth enamel was dealing with.

2. Large Fillings Can’t Be Held Into Place Easily

Fillings have the job of doing just that—filling a small hole so it doesn’t get bigger. At some point, the hole may be too large to properly hold the filling. You don’t want your filling falling out when you’re sleeping or eating because that can cause a domino effect of disasters; instead, if your dentist deems the whole too large for a filling, he might suggest a crown or even a dental implant to correct your issue.

3. Decay That Goes Into the Dental Pulp Can Cause Serious Problems

It’s important to stop decay before it spreads. If it makes its way to the dental pulp—where your tooth’s nerves and blood supply live—you could experience extreme sensitivity and pain. Poorly fitted fillings, or those that are old and past their useful lives, can contribute to this type of discomfort.
