Dental Crown: but a dental crown usually requires more tooth reduction than an onlay.

Pros 

  • They fit the cavity space perfectly. 
  • They can last longer than a dental filling. 
  • Help prevent decay by providing a tight seal. 
  • They help to distribute chewing forces evenly in the mouth and hence protect vulnerable teeth. 
  • Tooth-colored inlays/onlays can be matched exactly to the natural teeth and are aesthetic.

Cons

  • Requires two visits to the clinic
