What does “Restoration margin” mean?
The margin is the boundary where the end of the prosthesis or filling meets the natural tooth. The fit and location of the border are important when maintaining cleanliness and evaluating the condition of surrounding teeth and gums.
Where is the border?
Refers to the edge of the crown or the perimeter of the inlay/filling. Observation and management methods vary depending on the location, such as above, near, or below the gums.
What do I check?
The dentist checks for gaps, rough areas, overhangs, nearby decay, and gum inflammation. If floss catches or food repeatedly becomes trapped, that location should be examined.
Are all black lines gaps?
Lines may be visible due to changes in material, staining, or gum position. Rather than assuming leakage or cavities based solely on color, we evaluate actual fit and tissue condition.
Frequently Asked Questions
If the margins are visible, is the prosthesis wrong?
There are various reasons why the border is visible. We determine the need for repair or replacement by distinguishing between tooth fit, gum recession, and material characteristics.
Can I file down a rough margin at home?
Grinding arbitrarily may damage the prosthesis and teeth. Have your dentist check the uncomfortable area and make any necessary adjustments.
