3 Signs You Need to Replace a Dental Filling
- Posted on: Dec 15 2025

A consultation with an experienced dentist like Dr. Paul Covell can help you decide whether replacements are necessary. Patients from across the Pasadena, TX, area trust him for his blend of skill, training, and strong connection to his community.
This blog outlines three key signs to consider when evaluating your fillings.
1. You Feel Sensitivity or Pain
Sudden sensitivity to hot, cold, or sweet foods may indicate that your dental filling is wearing down or has shifted. When a filling starts to separate from the tooth, it can expose sensitive inner layers or allow bacteria to seep in — both of which can cause discomfort or even pain. If biting or chewing has become difficult, it’s best to have your dentist check things out.
2. The Filling Is Cracked or Missing
Fillings can crack under pressure, especially if you grind your teeth (also known as bruxism) or chew hard foods. In some cases, they fall out entirely.
A missing or broken filling not only affects how your tooth looks and functions, but also leaves it vulnerable to decay or infection. Catching this early can prevent the need for more invasive treatment, such as a crown or a root canal.
3. Your Filling Is Discolored or Stained
Another warning sign that a dental filling may need to be replaced is discoloration or staining around it. If the edges of the filling or the surrounding tooth structure appear darker, it can indicate that decay is developing under or around the filling. This subtle change is easy to overlook, but it can mean that bacteria have found a way in and are compromising the seal.
