Dental crowns have been the solution for tooth decay, tooth wear, breakage, cracking and even improper bite for a long time now. Dental crowns are also used to replace a missing tooth. Although dental crowns have multiple benefits, there are undeniable disadvantages of the same. Here are the common type of crowns and their advantages.
Pros of Dental Crowns
Apart from acting as a fix to fractured, foul colored and damaged teeth dental crowns improve function of teeth and enhance their appearance. They increase durability of teeth by at least 10 years provided the person maintains good oral hygiene and does not have habits like clenching and biting nails.
Dental crowns protect the tooth and wearing of surrounding teeth. Once the crown is planted, the damaged tooth regains its original shape. Dental crowns add strength to the teeth that have worn down and have become weak. This is true for most cases but their efficiency is judged by condition of gums as well as dietary and brushing habits. The type of crowns used is determined by face structure as well as appearance.
Cons of Dental Crowns
Cost is one of the chief concerns for people opting for dental crowns. Dental crowns are more expensive than tooth treatment with other materials such as amalgam. Dental crowns sometimes demand removal of healthy tooth structure. If a tooth nerve finds way to the crown the person experiences increased sensitivity to hot as well as cold foods and beverages. Sometimes the cement used to fixate the dental crown gets dissolved thereby allowing bacteria to settle under the dental crown and result in tooth decay.
Pros and Cons of Gold Crowns
Gold crown is preferred by many as preparation of tooth for this type of crown is the simplest. Gold crown saves much of the tooth structure from getting removed and leaves healthy part untouched. Gold crown also does not exert pressure on opposing teeth causing it to wear down.
Gold fits easily into the intersecting area between the gum and teeth. Gold offers healthy environment for gum tissue. However, gold crowns have one major disadvantage i.e. its cosmetic aspect. It stands out as an alien particle badly affecting your smile. This problem does not arise when gold crown is planted at the back of mouth.
Pros and Cons of Porcelain Crowns
Porcelain crowns, also known as new reinforced resin, are becoming increasingly popular as they enhance the aesthetic appeal of the face. It matches well with the natural tone of the tooth as well as surrounding teeth.
Porcelain crowns are not as strong as metal crowns and so need to be thicker to withstand daily chewing and biting. Since porcelain crowns are thick they demand removal of extra tooth structure (even if it is the healthy part) to improve aesthetic appeal. Sometimes dentist fail to get an ideal fit so that gums cling properly to the crown.
Porcelain crowns also cause gingival inflammation in people. Besides, planting porcelain crowns demand better skill. Also all-porcelain crowns happen to chip. In case of small chips, the crown can be repaired with the help of composite resin without the need for removing the crown. However, in case of bigger chips, crown needs replacement.
Pros and Cons of Porcelain Fused-to-Metal Crowns
These crowns were developed to overcome the drawbacks of all-porcelain crowns. The best thing about these crowns is that they look natural. Since they consist of metal substructure, they need opaque below porcelain.
The opaque is not capable of replicating the natural teeth’s translucency. The difference becomes visible when gums recede at old age and dark line becomes prominent at the meeting point of the crown and the gum.
