Have you ever felt a sharp sensitivity right where your tooth meets your gum? That uncomfortable feeling might be more than just a fleeting twinge—it could non-carious cervical lesions
What causes non-carious cervical lesions?
Abfractions result from a loss of tooth structure near the gumline.
Bruxism: Teeth grinding or clenching can exert excessive force on the teeth, making them more susceptible to abfraction.
Excessive stress or forces applied to the tooth, which leads to the breakdown of tooth structure at the cervical area (where the tooth meets the gum line).
It is thought that the excessive forces cause flexure or bending of the tooth structure, particularly at the thin cementum layer near the gum line, leading to microfractures and eventual loss of tooth substance.Stresses from biting and chewing can cause tooth flexure, weakening the enamel and dentin over time.
Malocclusion: Poorly aligned teeth or a misaligned bite can result in uneven distribution of forces during biting or chewing, increasing the risk of abfraction.
What symptoms do cervical lesions cause?
A wedge-like “V” or “C” shape at the base of the tooth
“V” or “C” shape at the base of the tooth
-Tooth Sensitivity to hot, cold, or touch.Abfraction is typically not painful, but it can cause tooth sensitivity, especially to hot and cold temperatures.-
Tooth Sensitivity
-Gum recession
Gum recession
Is abfraction serious?
-If left untreated, it can lead to further loss of enamel and dentin and cause further severe sensitivity,
-Cracks,
-Tooth infection causing severe pain.
What is the treatment for abfraction?
This can include dental bonding, dental fillings, dental crowns, or other restorative procedures to rebuild the damaged tooth structure and prevent further deterioration.
-Orthodontic treatment for correcting bite alignment
-Adjustments to ease occlusal forces
-Root canal tratment if pain persist.
