Crowns
Dental crowns are much stronger and more permanent than fillings. They are normally fitted to repair broken teeth or teeth weakened by decay or a large filling. Crowns can improve the appearance of a tooth or even hold a bridge or denture in place.
Ultimately, a crown is a protective cover that fits over a broken or decayed tooth, which is why a crown can be called a cap. It can be made of porcelain bonded to precious metal (looks very natural so this is good for front teeth), ceramic (a metal free alternative), glass or gold-alloy (very hard wearing).
The dentist will discuss the options available and advise if they think a crown is the best solution. If you do decide to go ahead, you will require at least two appointments. The first to prepare the tooth for the crown, create an impression and cover the tooth with provisional restoration. The second for cementation of the permanent crown. If you are having a crown fitted to your front teeth you may require more than two visits, to ensure an exact cosmetic fit.
Bridges
If you have a gap left by a missing tooth this can put more strain on the teeth either side and affect your ‘bite’ as the teeth next to the space can lean into the gap and change the way the upper and lower teeth bite together. This can then lead to food getting stuck in the gap, causing decay and gum disease.
Bridges may be the answer.
Bridges are exactly that: a bridge. Most bridges are fixed prosthetic devices that cover the gap between existing natural teeth or implants. The adjacent teeth are prepared as crowns and hold a false tooth in place.
Your dentist will be able to let you know at your examination appointment if a bridge is suitable for any missing spaces you have.
