Dental Crown Procedure Necessities
There are a big variety of crown types that a dentist can use like porcelain, ceramic, stainless steel and resin. Most crowns for cosmetic reasons are made of ceramic or porcelain. The ADA or American Dental Association state that with each type there will be pros and cons. Therefore, you need to address your dentist for your specific situation and let him recommend which will be the best to use for your tooth.
The need for a dental crown
Most of the common reasons that a person might require to restore their tooth with a dental crown, can be one of the following situations:
With a large filling: - When your tooth has a fracture or cavity that involves a half or more of your tooth width, you will need a crown to cover it. This means that the tooth that remains around a big filling is weak and prone to fracture.
A root canal: - If you had a root canal of a tooth, it will always need an immediate restoration with a crown to prevent fracturing. The reason is that with treatment of a root canal the tooth will be left hollowed out, which will predispose your remaining tooth to crack.
Syndrome of a cracked tooth(internal cracks): - With this condition, the patient will have inside tooth fractures which will cause pain if they chew in a specific way. This will produce stress on that fractured lines and it will feel as if it has split apart. When the tooth is crowned it will distribute the stress throughout your tooth evenly, and in most cases eliminating your pain. In this situation it will be wise to leave your temporary crown on until you are sure that the pain is gone and you won’t need a root canal.
Cusps that are broken: - Cusps can break off frequently due to existing large fillings or trauma. They are that part of your tooth that will take most of the stress when you chew. They have to be covered completely or either the filling or the tooth will keep on fracturing. If the tooth breaks right down to the bone, it will be necessary to lengthen the crown. This means the gums and bone will be trimmed to below the fractured edge of your tooth, to make sure the crown will be placed on a strong and healthy tooth structure.
Excessive wearing of your teeth: - When you have a habit of grinding your teeth, it will shorten the teeth over time. The wearing of your teeth can also be caused by acid erosion, that is caused either by bulimia, gastrointestinal acid reflux or if you follow an acidic diet. The enamel sometimes can completely wear away and only leave soft, small teeth. Your bite might collapse over some time and your only option to restore the teeth in a proper way, will be to increase your bite and cover your teeth with crowns.
When your teeth have an undesirable appearance: - The appearance of teeth can be unacceptable due to shape, colour or big spaces between the teeth. It can be fixed to look beautiful and natural with crowns. A very conservative and effective way to enhance the appearance of your front teeth will be with dental veneers. Sometimes you might not even require shaving or preparing your existing teeth, to make it look natural.
Procedure for crowning
Most of the time two appointments will be enough for dental crown placement.
A minimal certain thickness will be necessary for all crowns. This will insure for adequate strength. Porcelain crowns will need enough of a ceramic thickness in order to create that life-like translucency. Most of your crown types will need a minimal thickness of about 2 millimetres or about a sixteenth of an inch. This means that each tooth for dental crowning will be reduced on all sides with at least this amount.
While the process of trimming is performed, the dentist will remove decay on the tooth or the tooth structure that is unsound or loose, as well as filling material. Because of this, there might be portions of the tooth that will be substantially trimmed.
Except from the tooth’s overall size that gets reduce, the dentist will need to trim it into a specific shape. It must have a slight taper form for the crown that allows an inflexible hard object to slip over the tooth.
The tooth shape is very important to provide retention and stability on which the crown sits, because the crown is not only being held into place by dental cement.
It will stay better in place if the tooth’s nub is larger and extends higher up into the interior of the crown, as well as the opposite sides being more parallel of the nub.
Certain times if the tooth had broken off or decay is extreme, the dentist will need to build it up first with a filling material in order to make it taller, and only then shape it for the crown.
The time between appointments might be about two weeks for the dental laboratory to manufacture your crown.
