Signs and symptoms Dental Tissue Malformations

The symptoms of dental tissue malformations are diverse, as they depend on the type of anomaly and the degree of affection it produces.

Diagnosis and treatment Dental Tissue Malformations

Once the dentist analyzes the patient’s symptoms and clinical history, they will perform a dental examination. Depending on the type of malformation, they may be able to diagnose it with a simple visual inspection or may require X-rays to observe internal damage.

The treatment to follow is highly variable, as it will be established according to the type of malformation and its severity, but it generally includes surgery or other corrective procedures.
