When your dentist gives you a crown, it is to cover an implant or a broken tooth. It is a cap made of porcelain although there are also crowns made of metal. Although an effective treatment, there are some risks:
– Potential nerve damage (paraesthesia)
– Increased sensitivity to heat and cold
– Susceptibility to bacterial growth if the crown is loose or not fitted correctly/well
Crowns can become loose or fall off; they can also break, fracture, or chip. But they can be replaced.
“Dental crowns are a good option to consider for patients whоѕе tooth hаѕ sustained severe damage. It іѕ аlѕо an ideal solution to yellow or discoloured teeth.”
