Noncarious Cervical Defects refer to small (may become large) notch defects at the gumline of the tooth which are not caused by decay. If you notice or can feel these defects at the gumline, they will need to be repaired over time.
What causes Cervical Defects?
These areas of tooth loss are often caused by clenching or grinding the teeth, creating enough load to flex the tooth slightly, popping off the thin layer of enamel over this area of the tooth. Also implicated in these defects is the consumption of soft drinks, including diet drinks which are acidic.
Since they are not decayed, is it necessary to repair them?
When small, these defects in the tooth are harmless. However, allowing them to become larger will endanger the tooth to fracture or exposure of the pulp (nerve).
Is repair of the defect difficult?
Normally, a bonding type material can be used, often without requiring the use of local anesthetic. This is a relatively simple dental procedure.
