Should a crown meet the gum line?
A crown is placed over the entire visible surface of a tooth down to the gumline. This is essential to help prevent harmful bacteria from leaking underneath your restoration. If a gap forms between the gum tissue and the restoration, it’s a sign your crown no longer fits.
Can a crown look natural?
In most cases, dental crowns look natural due to the talent of the particular dentist. Once a dental crown is placed upon an original tooth, it is usually difficult to distinguish between the crown and the rest of the natural teeth.
Why are my gums dark around my crown?
This blackline surrounding your gum occurs because light, which can pass through natural teeth, is unable to pass through the crown’s metal, makes the crown’s porcelain fusion look darker, and restricts the amount of light in the root and gum areas.
Does gum grow around crown?
The gums will close up around the crown itself so there’s very little risk that your tooth will develop cavities. However, it’s still possible to experience a cavity under a crown if you take poor care of your teeth or if your dental crown isn’t fitted properly.
Why do crowns look black?

Can a permanent crown be removed and put back?
