What does “Fracture of an artificial crown or tooth” mean?
A prosthetic fracture is a chip, break or crack in the material of a crown or artificial tooth. Assessment distinguishes damage to the covering restoration from a fracture that also involves the natural tooth underneath.
Identify which part has broken
A break in the visible tooth-shaped part may affect only the restorative material, or may involve its internal structure or the supporting natural tooth. The dentist assesses the fracture and the stability of what remains. A photograph alone cannot reliably establish the depth of damage or whether the restoration can be reused.
Treatment depends on the remaining structure
For a small surface defect, smoothing and polishing or repair by adding restorative material may be considered. If the remaining restoration or tooth underneath is unstable, or restoring function through repair would be difficult, temporary protection followed by replacement may be needed. The fracture location, material and remaining structure guide the choice between repair and replacement.
Check sharp edges and loose pieces
A broken edge may scrape the tongue or cheek, and fragments may become loose. Do not file it yourself or use household glue; keep any detached pieces to bring to the appointment. Severe pain or swelling calls for prompt dental assessment, and suspected inhalation of a fragment requires immediate emergency care.
Frequently Asked Questions
Does one chipped piece of porcelain mean the whole crown must be replaced?
Not always. A small defect may be suitable for smoothing and polishing or repair with additional material. Replacement may be needed depending on the extent of the fracture, the stability of the remaining restoration and the condition of the tooth beneath.
Can the natural tooth be intact when its restoration breaks?
Damage may be limited to the restoration material, but the natural tooth may also be affected. The restoration and the supporting tooth must be examined separately to determine this.
