Yes, dental fillings can deteriorate or fail over time.
While fillings are designed to restore damaged teeth and last for a considerable period, they are not permanent. According to research, fillings can indeed "go bad" due to various factors. The reference information states that fillings "can also fail or deteriorate over time." Here's a more detailed explanation:
Why Fillings Can Fail
Several reasons can lead to filling failure:
- Wear and Tear: Everyday activities like chewing and grinding your teeth put stress on fillings. This constant pressure can cause them to chip, crack, or wear down.
- Poor Oral Hygiene: Inadequate brushing and flossing can lead to the buildup of plaque and bacteria around the filling. This can cause decay to form underneath the filling, weakening the tooth structure and eventually leading to filling failure.
- Secondary Decay: As mentioned above, decay can develop around the edges of a filling if oral hygiene is poor. This is called secondary or recurrent decay and is a common cause of filling failure.
- Material Failure: The filling material itself may degrade over time. For instance, amalgam fillings can corrode, while composite fillings can shrink slightly, creating gaps between the filling and the tooth.
- Trauma: A direct blow to the mouth can damage or dislodge a filling.
Signs of a Failing Filling
Be aware of these signs, which may indicate a failing filling:
- Sensitivity to Hot or Cold: This is mentioned in the reference and is a common indicator.
- Pain or Discomfort When Biting Down: Pressure on a failing filling can cause pain.
- Visible Damage: Obvious cracks, chips, or holes in the filling.
- Rough Edges: Feeling a rough edge with your tongue might suggest the filling is deteriorating.
- Food Impaction: Food getting stuck frequently in a particular spot could signal a gap around the filling.
What to Do If You Suspect a Filling is Failing
If you suspect a filling is failing, it's crucial to see your dentist promptly. They can assess the situation and determine the best course of action, which may involve replacing the filling.
