What does it mean when gums recede and the veneer edge shows?
An exposed margin is partly cosmetic, partly a cleaning and sensitivity issue.
Veneer margins are placed at or just under the gumline, so when gums recede, a thin line of root or cement becomes visible. Recession happens gradually with age, aggressive brushing, thin gum tissue, or gum disease.
What an exposed margin changes
The exposed strip can look darker than the veneer, feel sensitive to cold, and trap plaque more easily than glazed porcelain. None of this means the veneer failed — but it does mean the area needs closer hygiene and monitoring.
Options range from watching and desensitizing care to margin repair or a new veneer, and the pace of recession differs from person to person. Have your dentist measure the recession and rule out gum disease before deciding how far to go.
