How easy is it to redo a crown, i mean, to remove the crown and clean the tooth in order for it to receive a new crown? How do we shape a new crown?

In brief: Easy for a dentist

This procedure is easy for a dentist to perform. The crown is made to fit the tooth, not the tooth to fit the crown.

In brief: Same as the first

Old crown is removed, tooth is cleaned of all cement and decay if any and a new impression is taken for the lab to fabricate the new crown, a temporary crown is place in the interim.

In brief: Not too hard

Easy to remove. Sometimes we can tap it off.
However with today's very strong cements it is safer to make a groove in the side and spread the crown so it releases from the tooth. Usually we will reshape the tooth that remains and make a new impression, a new temporary crown, and send all the information to the laboratory to make the new crown. They use this information to custom build the new one.

In brief: No slam dunk new cr

I wouldn't say it was "easy" to redo a crown, as there are many instances where the new crown may take much more extensive treatment than the original crowning of the tooth required.
The new crown is done because there is a problem with the old crown or the tooth underneath that may cause the need for root canal tx, or crown lengthening surgery and decay removal in order to make the new crown.

In brief: Simple

The current crown is sectioned or cut to remove it.
The tooth is then repaired if necessary and reshaped, an impression is the taken of this tooth, and a temporary is made. You return two to three weeks later for the placement of the or permanent crown.

In brief: Easy f tooth healthy

Generally easy if underlying tooth is in good shape.
Most of the tooth preparation has already been done so just some smoothing and refining is all that is needed. If there is decay, that would be cleaned up as well. As long as there isn't a surprising amount of decay under old crown, redoing a crown is easier than starting from scratch. Good luck.

In brief: Very Easy

The crown is easily removed with a crown bumper or handpiece.
If there is any decay underneath it can be removed, if there is severe decay the tooth may require a root canal. The trooth may require a "build up" which will then be prepared for a new crown.

The ease of redoing a crown depends on several factors. First, what is the reason for the replacement crown? All crowns will eventually fail if you live long enough, so it is not unusual to have to redo a crown. The life span of crowns depends on several factors: how well the tooth was prepared by the dentist, how precise the laboratory made the crown, your medical conditions, and how well you maintain the crown by brushing it and flossing it daily. (In my opinion, cements, while very strong these days, are not as important if the tooth was prepared ideal and the crown was made to fit very intimately. Otherwise how do we see crowns in service for 40-50 years that are still functional, knowing that zinc phosphate acts only as a liner and has no bonding properties to the crown or the tooth)? That being said, crowns should last a very long time. Certainly a lot longer than the 5-10 years that insurance companies are willing to pay to replace them. The previous dentists are correct that redoing a crown can be straight forward barring any unforeseen complications. If there is recurrent decay, what is the extent? That will determine whether a replacement crown is sufficient or if additional treatment is required; such as a build up, root canal, or post and core. Sometimes we really don't know what needs to be done until we remove the crown and assess the tooth with our view unimpeded. X-rays tell us whether there is decay below the margins of a crown, or whether there is any periapical pathology, but not the extent of decay under the crown itself. Plus most of the time fractures will not be visible radiographically. So it really depends. Each case needs to be assessed individually for the appropriate care to be determined. Redoing a crown can be easy/not too difficult, depending on its diagnosis and extent of disease and damage.
