Why do I need a dental crown?
The patient will have a crown after the root canal. A dentist who has to perform a root canal on a tooth proves that the tooth is already very much chipped. Even if the root canal is successfully completed, the tooth tissue becomes so fragile that the tooth breaks easily during chewing. At this point, the tooth loses its normal chewing function, and the dentist is unable to restore the chewing function even with filling materials.
Healthy teeth are responsible for chewing food. When you eat, your teeth have to bear a lot of bite force. Usually, the front teeth bear 10-30 kg and the back teeth bear 50-70 kg. After root canal treatment, the tooth loses nutrients from the pulp and like a tree that has lost its roots, it slowly withers and becomes fragile, which increases the likelihood of fracture when the tooth is chewed. Therefore, the patient needs to wear a crown to protect the tooth after the root canal treatment.
How are dental crowns made?
The dentist makes a crown in 6 steps: determines the size of the crown, grinds away any teeth that don’t fit, makes a model, compares the color of adjacent teeth, puts on the crown and observes it.
In the first step, the dentist determines the size of the crown. The dentist uses a mold and presses repeatedly on top of the tooth to determine the exact shape of the crown.
In the second step, the dentist grinds away the tooth that does not fit. After determining the size of the crown, the dentist will need to grind away some of the tooth to keep the tooth straight so that the crown does not exceed the thickness of the original tooth when it is placed. Sometimes, the dentist will grind away portions of two adjacent teeth.
In the third step, the dentist compares the colors of the adjacent teeth. The dentist will take out several different colored crowns and compare them to the color of the patient’s teeth. The dentist will determine which color crown is closer to the color of the patient’s teeth.
In the fourth step, the dentist will develop the appropriate model. Using temporary materials, the dentist will develop a preliminary model of the crown. Before the crown model is sent to the factory for fabrication, the dentist must make a record of the prepared crown, which will contain all the data on which the crown will be produced by the mold maker.
In the fifth step, the patient wears the crown and observes it. After about 1 week, the crown made by the mold maker is ready. After comparing the data, if the dentist confirms that there are no problems, the dentist will bond the crown to the tooth through a special bonding agent. At this point, the step of the patient wearing the crown is complete.
Types of Dental Crown Materials
Categorized according to the material used to make them, crowns can be divided into precious metal crowns, porcelain crowns, porcelain crowns, stainless steel crowns, and temporary crowns. Precious metal crowns, porcelain crowns, and porcelain crowns are designed by the dentist according to the patient’s condition and then given to the factory for fabrication. Since it takes a week to make the crown, the patient will be fitted with a ready-made temporary crown to protect the tooth temporarily after a portion of the tooth is removed.
Longevity of dental crowns
The lifespan of a dental crown is basically about 10 years.After 10 years, the bonding agent for the crown will dissolve because the mouth is a moist environment. If the dentist is less skilled, resulting in a crown that does not fit properly between the crown and the tooth, the life of the crown will be shortened. A poor fit between the crown and the tooth leads to bacteria attacking the tooth inside the crown, causing darkening and erosion of the tooth. The tooth is painless after root canal treatment, and it is difficult for the patient to feel erosion when the tooth encounters erosion. Continued erosion of the tooth leads to decades of total erosion gone and the crown falling out automatically.
How to Care for Crowns
Avoiding unreasonable forces, paying attention to oral hygiene to maintain periodontal health, and taking timely treatment for regular review are all means of maintaining longevity.
