A poorly done dental filling can cause discomfort that goes beyond temporary sensitivity. Identifying it early is key to preventing infections, persistent pain, or more complex treatments. Many people assume that pain after a filling is normal, when in reality it may be a sign that something is not working properly.
What is a poorly done dental filling?
A dental filling is intended to remove decay, seal the tooth, and restore its shape and function. A filling is considered poorly done when it does not properly adapt to the tooth or fails to perform its protective function, allowing leakage, pain, or bite problems.
- It does not properly seal the cavity
- It is poorly adjusted when biting
- It allows bacteria to enter
- It causes persistent pain or inflammation
This issue can occur with resin, composite, or amalgam fillings, and it does not always appear immediately after treatment.
Most common symptoms of a poorly done dental filling
There are several signs that may indicate the presence of a poorly done dental filling and should not be ignored.
- Pain when chewing or closing the mouth
- Intense sensitivity to cold, heat, or sweet foods
- Continuous pain days or weeks after the filling
- Gum inflammation around the treated tooth
- A sensation of a high or poorly fitted filling
- Persistent bad breath
- Color change in the filled tooth
A properly done filling should not cause prolonged pain once the initial adjustment period has passed.
Is it normal to feel pain after a dental filling?
Difference between normal pain and concerning pain
After a filling, it is normal to experience mild sensitivity during the first 24 to 72 hours. However, pain is no longer normal when it worsens over time, lasts more than a week, appears as throbbing or nighttime pain, or radiates to the jaw, ear, or head. In these cases, there is usually a problem with the fit, seal, or involvement of the dental nerve.
Most common causes of a poorly done dental filling
Incorrect sealing
When a filling does not seal properly, bacterial leakage occurs, which promotes the development of decay under the filling and possible infections.
Filling that is too high
A filling that protrudes more than it should alters the bite, causing pain when chewing, jaw overload, and tooth wear.
Proximity to the dental nerve
In deep cavities, poor isolation or insufficient protection of the nerve can cause pulp inflammation, even if the filling appears correct externally.
Inappropriate material
Using an incorrect or poorly cured material reduces the durability of the filling and increases the risk of discomfort and leakage.
How can you tell if a filling is causing tooth sensitivity?
Persistent sensitivity is one of the clearest symptoms of a defective filling. If pain appears when exposed to cold and does not fade quickly, if you feel sharp pain when breathing in cold air, or discomfort without an apparent stimulus, there is likely an issue that requires professional evaluation.
Risks of not correcting a poorly done dental filling
Failing to treat a defective filling in time can lead to infections, secondary decay, the need for root canal treatment, tooth fracture, or even tooth loss. Many of these problems could be avoided with early correction.
What to do if you suspect you have a poorly done dental filling?
Visit a dental check-up
The dentist will assess the bite adjustment, the seal of the filling, possible nerve involvement, and the presence of secondary decay. Acting early allows for simpler and less invasive solutions.
Solutions for a defective dental filling
Solutions depend on the condition of the tooth and may include adjusting or polishing the filling, completely replacing the material, using a more suitable restorative material, or, in advanced cases, a root canal. Most poorly done fillings have a solution if they are detected early.
Conclusion
A poorly done dental filling should not be ignored. Persistent pain, sensitivity, or inflammation are clear warning signs that something is wrong. Detecting it early protects oral health and helps avoid more complex treatments, so when in doubt, a professional dental check-up is always the best decision.
