Understanding Secondary Occlusal Trauma: Causes and Symptoms

Secondary occlusal trauma refers to the damage that occurs to the teeth and supporting structures due to excessive forces, even though the teeth themselves are healthy. Unlike primary occlusal trauma, which is caused by malocclusion or abnormal tooth contacts, secondary occlusal trauma can be attributed to other factors. This article aims to shed light on the causes and symptoms of secondary occlusal trauma.

1. Bruxism:

One of the primary causes of secondary occlusal trauma is bruxism, a condition characterized by the grinding or clenching of teeth. The excessive force generated during these activities can lead to trauma on the teeth and surrounding tissues. Over time, this can result in tooth sensitivity, increased tooth mobility, and even tooth fractures.

2. Parafunctional habits:

Parafunctional habits, such as nail-biting, pen-chewing, or using teeth as tools, can also contribute to secondary occlusal trauma. The repetitive and excessive forces exerted on the teeth can cause wear, chipping, and even the displacement of fillings or restorations.

3. Trauma from habits:

Habits like aggressive tooth brushing, using a hard-bristled toothbrush, or applying excessive force while flossing can lead to secondary occlusal trauma. These habits can wear down the enamel, cause gum recession, and even damage the underlying tooth structure over time.

It's important to recognize the symptoms of secondary occlusal trauma to address the issue promptly. Some common symptoms include tooth sensitivity, pain while biting or chewing, jaw pain or discomfort, and headaches. If you experience any of these symptoms, it is advisable to consult a dental professional for a proper diagnosis.

To prevent secondary occlusal trauma, it is essential to establish good oral hygiene habits. This includes using a soft-bristled toothbrush, avoiding parafunctional habits, wearing a mouthguard during sleep if you have bruxism, and seeking treatment for any underlying dental conditions.

In conclusion, secondary occlusal trauma can result from various causes, including bruxism, parafunctional habits, and trauma from habits. Recognizing the symptoms and adopting preventive measures are crucial in maintaining oral health. Regular dental check-ups can help identify any signs of secondary occlusal trauma early on, allowing for timely treatment and prevention of further damage.
