What is the procedure for inserting a crown?
First of all, old and defected fillings must be removed and decayed fillings need to be redeveloped. No old amalgam remains or caries can remain under a crown! The dentist usually controls root-treated teeth and checks whether there is a granuloma on the root canal (inflamed tissue at the tip of the root canal). Furthermore the health care professional has to determine if the jawbone is still healthy or if it has already deteriorated (an x-ray will be prescribed). Diseased gums and periodontia must also be repaired before a new crown is inserted.
In some case, the patient must first undergo root canal treatment before inserting the crown. If someone gets a crown after root canal treatment and the old tooth is in bad condition, the dentist puts a post and core in the root canal to support the crown. This is the final option before the tooth is lost. If the patient does not need a pivot tooth, the dentist grinds the tooth down until it is cone-shaped. He then takes an impression of the shape of the tooth and of the jaw above to get a perfectly adjusted bite. The mold hardens in a few minutes and can then be removed from the mouth. As long as the crown is made by the dental technician in the laboratory, the patient does not need to remain without teeth. He will receive a temporary crown made out of plastic. However, this crown only lasts for a short amount of time.
How long does the treatment normally take?
In the best of cases, it takes five days for the crown to be fully inserted into the jaw. The patient needs to see us at least two or three times. The first visit is the longest. During the first appointment, the preparations, such as removing old crowns or bridges, and tooth polishing, are made.
This is followed by the impression, the definition of the color, and the making and fixing of the temporary crown. During the next one or two appointments, the dentist checks with the patient to see if the shape and color of the crown have met expectations. If both are satisfied with the results, the crown will be cemented.
How painful is the preparation for the crowning?
Thanks to our attention and local anesthetics, the preparation for the crowning is painless. If there are no nerves left in the tooth or the post crown has already been put in, local anesthetics are not needed.
What are crowns made of?
Artificial crowns can be made from different materials with the most common ones being all ceramic crowns, metal ceramic crowns and gold crowns.
What do I need to do to keep my crown in good condition for a long time?
A crown can normally last 10 to 15 years. To ensure that your crown remains in good condition for a long time, you must pay close attention to your dentist's instructions and keep good oral hygiene. Plaque and calculus can also build up on the surface of the porcelain and, like for natural teeth, can lead to different dental diseases.
The crown is the last part of a long chain of treatments: everything must first be cleaned up, then the crown is done. A crown is necessary if the part of the tooth coming out of the gums is so damaged that is no longer recoverable through other dental methods (aesthetic fillings, inlays).
The artificial crown is a cap that is placed over the damaged tooth by the dentist. The cap looks like a natural crown, adapts to the rest of the tooth and strengthens it. The crown protects the tooth from breaking and preserves its color. You cannot see the metal from the outside, because the metal base is blended with a tooth-colored cover.
These are called porcelain crowns most of the time. This type of crown is made of a metal base (gold, nickel, palladium or chrome) and a fused ceramic blend. The crowns blended in ceramics are aesthetic, hard, stable, and durable, which make them a particularly good choice for molars.
