When fillings fall out or get damaged, one might feel like their tooth is done for. However, that’s simply not the case. If enough tooth structure remains, a tooth can be filled multiple times.
So, don’t worry if your filling is no more! In this blog, let’s understand why teeth require fillings and the conditions in which a tooth can get multiple fillings. Additionally, since older fillings can get worn down, you might need a replacement, so we’ll learn to identify when your fillings should be replaced.
Why Do Teeth Require Fillings?
Teeth are made from the hardest substance in the body: enamel. But despite their sturdiness, enamel can be vulnerable to decay caused by acid-producing bacteria. Other causes of enamel wear are excessive teeth grinding (bruxism) or physical trauma.
The bottom line is that enamel is not invulnerable. That’s where fillings come in. Made from highly durable materials such as composite resin or ceramic, they can easily close the cavity left by decay. Fillings can also restore and seal the tooth’s structure, preventing further decay and preserving the tooth.
When Does One Tooth Get Multiple Fillings?
One tooth can get filled multiple times; however, this procedure is recommended under several circumstances.
- Recurrent Decay
If the same tooth gets decayed and develops additional cavities, fillings might be used to seal it. - Material Compatibility
Due to their unique chemical makeup, filling materials vary in lifespan and properties. Since amalgam fillings can cause sensitivity in some individuals, they might opt for filling replacement. - Extensive Damage
Refilling might be considered if a filling has failed but the tooth has enough structure to support another one.
However, frequent filling changes in a single tooth could indicate underlying problems. A dental evaluation is essential to determine whether an alternate approach is better.
It should also be considered that multiple fillings can weaken the tooth structure as more of the natural tooth may be drilled away. Hence, it may result in fractures or cracks. Since the seal between the tooth and filling becomes compromised, the tooth may also become vulnerable to decay. Overall, dental professionals opt for refillings in certain cases as long as they won’t damage the remaining tooth extensively.
How to Identify if Your Fillings Need Replacement
Older fillings can be worn due to chewing and biting forces in everyday life. There are some key signs that your fillings need replacement.
- Cracks or Chips
One key sign that a filling might need replacement is visible cracks or chips in the filling itself. Biting down on hard food can sometimes cause fillings to break, which can lead to decay if the tooth isn’t sealed properly. - Tooth Pain
Experiencing pain in the tooth with the filling, especially when biting or chewing, can signal that the filling might be failing. The pain indicates that bacteria might have infiltrated the tooth, potentially leading to infection or root canal issues. - Sensitivity
Increased sensitivity to hot, cold, or sweet foods means a filling has been compromised. If you feel discomfort when consuming them, the filling may compromise and affect the tooth’s nerve. - Discoloration
Fillings can change in color over time. They might oxidize and appear darker or yellowed, and metal fillings might tarnish, signaling the need for replacement. - Leakage
If there is a gap between the filling and the tooth, saliva and bacteria may enter. This can lead to decay underneath the filling. You can observe this phenomenon as the edges around the filling might darken. - Bad Breathe or Taste
Persistent bad breath or an unexplained unpleasant taste in your mouth indicates decay that has developed around a failed filling. It is due to bacteria thriving in areas that are not sealed properly.
End Note
Fillings are a great way to preserve the integrity of your teeth, keep them functioning, and restore their aesthetics. In some cases, multiple fillings on the same tooth might be needed, especially when cavities are present in areas the initial filling has not covered.
However, multiple fillings can compromise the tooth structure due to repeated drillings needed to fit them. So, a dental evaluation is required to determine whether the tooth structure can support another filling or if alternate dental treatment is needed.
