Hi @augustine-west, thanks for your question!

Dental crowns usually last from 10 years, and up to 30 years or more if well-cared for. Ultimately, it is dependent on the care of the tooth structure that is supporting the crown that determines the longevity of the crown. 

The process usually goes like this:

1st visit: Consultation with the dentist about the suitability of having a crown placed on the tooth, and which material (ceramic, metal, hybrid, etc.) will be best.

2nd visit: Preparation of the tooth structure by shaving (usually about 1mm all around) the tooth to the necessary dimensions to accommodate the crown. A temporary crown will be placed for about 2 weeks before the lab makes your final crown.

3rd visit: Cementation of the crown if it fits well.

To ensure that your crown is well-cared for, 6-monthly scaling and polishing appointments are recommended.

Hope this clarifies your question!
