Why do I have a black line at the base of my crown in Glen Iris?

Over time, it is common for black lines to form at the base of a crown or become visible on the gums surrounding your crown. Typically, this is a cosmetic issue and usually causes no pain.

If you do experience pain, it is important to see a dentist as soon as possible.

Black lines can appear on crowns for several reasons, whether it’s an individual crown or one placed after root canal treatment:

Having a porcelain-fused-to-metal (PFM) crown. As your gums recede over time, the metal portion at the top of your crown may be exposed.
Staining caused by the metal on your PFM crown where the gums meet the metal.
Cavity formation between the crown and gums.

Dr. Daniel Kaufman can assess the cause and recommend an appropriate solution, which may include:

Replacing an old crown with a fully porcelain crown to eliminate black lines and stains.
Treating any cavities promptly to avoid further complications.

All treatments should be supported with good dental hygiene at home and regular check-up and hygiene appointments at the dental practice. If you noticed a black line around your crown, schedule an appointment for a consultation with Dr. Daniel Kaufman.
