Dental crowns are used to cover severe tooth defects and create an artificial seal against bacteria and infection. The crowns are tooth-shaped caps that are placed over teeth, augmenting their strength and structure.
There are multiple types of materials available to make crowns, providing varying degrees of visibility. They cover the portions of tooth that exists just above the gum line.
Dental crowns should not be used to correct mild tooth deficiencies that can be solved easier with whitening, veneers, or bonding. It is a procedure that is best suited for those with severe defects, as some shaping is necessary.
There are many types of veneers available for your specific situation. Contrary to what the name implies, full gold crowns are often made from a mixture of different alloys, including platinum, gold, palladium, silver, tin, and copper.
The mixture used is dependent on size, tooth density, durability of material, and space available. These crowns are generally reserved for teeth located in the rear of the mouth as they can easily withstand bite pressure.
People with metal allergies should avoid this type of crown and use a resin or porcelain based one instead. Porcelain fused to metal crowns are a hybrid of both the porcelain and metal processes.
It is driven by aesthetics, creating a naturally white tooth with the strength of the underlying metal. The layer of metal provides an accurate fit over the surface of the teeth.
Gum care becomes especially important as receding gum lines can reveal the lower layer of metal. Resin crowns are affordable and efficient.
The base material is made of a reinforced resin composite and requires more upkeep than traditional crowns. New acid etching techniques help create an accurate and natural looking tooth.
As the most popular base, porcelain crowns provide a realistic surface, while effectively protecting the delicate tooth inside. The material is extremely durable, resistant to breaks and stains, and can be matched to any shade.
The translucent material helps it blend seamlessly with your surrounding teeth. These crowns are typically used on the front teeth as those in the rear receive the most pressure when chewing and biting.
The type of crown that is best for your situation can best be determined with a consultation at our offices. Your previous dental history and present condition can greatly impact which crown is best or if crowns are not the best option for your situation.
X-rays are then taken to determine the strength of the tooth and surrounding area. If damage to the root is excessive, it may be unsafe to install a crown until a root canal takes place.
When a crown is applied, the existing cavity or defect is shaped to provide a stable base and room for the new material to be placed. This is done after applying general anesthesia.
The amount of shaping fluctuates based on the type of dental crown chosen. If large portions of the tooth are missing, a filling may be used to recreate structure for the crown.
Impressions of the tooth in question and surrounding teeth are then taken to make sure the specifications are accurate. The impressions and information gathered are sent to the dental laboratory, where experienced technicians will craft your custom crown.
Long-term care is important in extending the lifespan of your crown. The following tips can help ensure that you keep a sparkling smile.
Solid foods that may crack your teeth should be consumed with moderation. Metal crowns are extremely durable, but those made of porcelain or composite may chip under extreme pressure.
Avoid things that may discolor or corrode the bonding cement or porcelain surface, such as coffee, certain spices, and red wine. Please contact your dentist immediately if you are prone to grinding your teeth.
Crowns require a healthy gum line. The more that gums recede, the more apparent the difference between the natural and artificial tooth.
