It is often said that dental crowns offer long-lasting protection to damaged teeth, but what if your tooth crown develops decay under it? It is a seemingly odd situation, where a protective measure fails to work. However, do not worry, in this blog we have discussed all the reasons why this might happen so you can benefit from it.

The Causes of Decay Under Crown

Dental crowns are made in a way that shields and strengthens damaged teeth by encapsulating them. However, there are times when decay manages to creep in under the crown as well, causing discomfort. Let’s take a good look at why this happens so you may avert it.

  1. Pre-Existing Decay
    Although the chances are slim if a cavity or decay remains undetected before crown placement, it can spread under the crown. This presence destroys the underlying tooth structure, resulting in decay. In such a situation, regular dental checkups are crucial for identifying and addressing any pre-existing issues.
  2. Poor Oral Hygiene
    Plaque and bacteria are always lingering on your teeth if not brushed off on time. Their accumulation around the edges of the crown can serve as a breeding ground for decay. Think of it as leaving a tiny open door for trouble.
  3. Fit and Placement
    When a crown fails to fit perfectly, it feels like a leaky roof. If there are gaps between the crown and your tooth, food particles and bacteria can go in and cause decay in that tooth area under the crown. A well-fitting crown is essential for a strong and healthy result.
  4. Material
    Crowns are available in different materials, each with its own susceptibility to decay. Porcelain crowns repel decay, while metal crowns, although strong, can conduct heat and cold, increasing the risk. Choosing the right material with your dentist is key for successful placement and health after.
  5. Diet and Lifestyle
    Sugary snacks and drinks are a strict no-no. These decay-causing bacteria and the habit of smoking further weaken your oral defenses. Maintaining a healthy diet and lifestyle plays a significant role in protecting your crown and teeth.
  6. Infection
    Decay may escalate into a full-blown infection if you let it be. This results in pain, swelling, and sensitivity.
    Post-Procedure Pain
    While some discomfort after a crown procedure is normal, prolonged pain is not a good sign and often indicates decay or infection under the crown.
  7. Hidden Cavity
    Just because you cannot see it does not mean it is not there. A cavity developing under the crown is a major source of pain within the tooth itself. Regular dental exams are essential for detecting hidden decay.
  8. Food Traps
    Cavities are unwanted spaces between the tooth and the crown. They open the gap for food particles to trap in them.
  9. Skipping Checkups
    Dental checkups are your best line of defense against undetected decay. Regular professional cleanings and examinations can identify problems early on and prevent them from getting worse under your crown.
