A filling is used to repair a cavity before the decay advances. It protects vulnerable areas of the tooth from bacteria while also ensuring the enamel is strong enough for biting. Unfortunately, fillings can become worn or compromised over time and need a dentist to repair them. Here are a few signs your dental work needs immediate attention.

When Does a Dental Filling Need a Replacement?

1. Tooth Pain & Sensitivity

Sharp, shooting tooth pain is often linked to cavities. However, it can also result from a damaged or displaced filling. The interior tooth pulp contains a mass of nerves, and when these nerves are exposed, it can cause sudden acute aches. 

Also, pay attention to any new sensitivity affecting the filled tooth. You might experience issues with hot or cold foods, as temperature extremes are known to be uncomfortable when enamel is compromised. Very sweet foods can also cause discomfort when the interior of the tooth isn't protected. Oral bacteria feed on sugars and release acids, which are a major factor in tooth decay.

2. Visible Damage

When dental work is in a visible area of your mouth, you might also notice damage when brushing or flossing. The filling can appear cracked, loose, or bent. Even if the issue is not painful, visible damage requires an immediate assessment by a dentist to prevent worsening effects. 

In some cases, the filling might fall out if the damage is significant enough. This tends to occur while eating, as the act of biting down is usually the last push the dental work needs to completely break loose. 

3.  Age

Even with good dental care and regular visits to the dentist for cleanings, most fillings have a life span between 10 and 15 years. This usually depends on the type of material used. 

Amalgam types, which are made from different metals, can last up to 15 years. While durable, some patients don't like the unnatural look of metal fillings. Composites, which are made from tooth-colored resins, blend in seamlessly with other teeth and have a life span of about 10 years. 

If you have an older filling and are concerned about its condition, your dentist can use a special tool called an explorer to determine whether the bonds of the material are still holding tight. Known for the friendly, soothing atmosphere, Elm Dental Care provides a wide range of dental services to patients throughout New Town, MO.
