Re: Once a tooth is crowned can you keep this for a lifetime
Yes and no. Crowns are usually good for many, many years, however, sometimes a cavity will develop at the bottom edge of the crown on the tooth requiring the crown to be replaced and tooth ground down more. Even when the tooth is ground down a lot they can put a pin in the tooth to help hold a new crown.
Some of my molar crowns are 45 years old and have not been replaced.
Sometimes a tooth will have decay under the crown, but, they can drill thru the crown in order to do a root canal or fill the cavity. Amazing what they can do these days.
There is a possibility the tooth will have problems requiring removal, however, this is usually determined at the time a crown is being discussed.
