Good Crowns Vs Bad Crowns …..What to Look For

 

Dentistry is both a science and an art.  A good dentist must have the skills and attention to details in order to deliver a quality restoration. This is never more true than when it comes to crowns and bridges. Here are some guidelines as to what makes a good crown vs a bad crown.

 Qualities of a Good Crown:

  • Perfect fit at the margins and to the adjacent teeth
  • Proper emergence profile of the crown from the gum line
  • Excellent contact between the neighboring teeth
  • Excellent occlusion, i.e the fir of the crown to the opposing teeth
  • Excellent color to match natural teeth

Qualities of a Bad Crown:

  • Poor fit- this results in recurrent decay, sensitivity and ultimate failure of the crown
  • Over contoured crown- this results in inflammation of the gum tissue, gum disease and movement of the crown by muscle forces
  • No contact between the adjacent teeth-results in movement and tipping of the crown
  • Poor color and not natural looking
