Modern dentistry allows patients to have the white, blemish-free smiles they have always wanted. Everyone's dream smile looks different and is unique to them as a person. However, countless people prefer to avoid having dark lines or residue around their restored or natural teeth.
PFM Restorations and Dark Lines
Porcelain-fused-to-metal (PFM) restorations are made of different metals, such as titanium alloys, gold alloys and base metal alloys. Base metal alloys commonly include cobalt, nickel and chromium.
Though base metal alloys are popular for many patients, people with metal allergies tend to avoid these restorations. The crown itself is matched to the patient's natural dental shade, but the base is metal.
A dark line may be visible if the PFM crown's margin is exposed. Visible dark lines may also peek from beneath the crown if a patient has receding gums.
Finally, a black or dark line around a crown may indicate tooth decay. Though a crown protects natural tooth structure, decay can still occur, especially at the crown's margin.
Customised Crowns for Your Dream Smile
Bayside Family Dental Care provides patients with crowns that look, feel and function like natural teeth. Dr Chad Henderson can replace a PFM crown with an all-ceramic or zirconia crown that creates a seamless smile. Neither zirconia nor ceramic crowns contain metal, so there's no risk of seeing dark lines.
We invite your call if you have dark or black lines on a restored tooth or you would like to replace a PFM crown.
