The root canal treatment of primary teeth and permanent teeth may be different, so is there any difference in the crown to be worn after root canal treatment? The main purpose of putting crowns on teeth after finishing root canal treatment is to protect the teeth. This is the same for primary and permanent teeth. When the tooth decay is serious, the teeth have become very fragile. Wearing crowns can be more effectively to protect the teeth, so that the teeth can maintain their chewing function and support them to the age of tooth replacement.
Dental crowns are cemented to the crowns of teeth. The crowns used for primary teeth have a relatively short using time, the teeth will be replaced by permanent teeth afterwards. Therefore, it is less necessary to grind the teeth down and then do impression to customize the crowns. The pediatric dentist can usually use the ready-to-use crowns, try on and choose the appropriate size for the children, and then fix the crowns on the teeth with dental adhesive.
And for the material selection, stainless steel is generally used for the crowns of primary teeth, which is strong enough and cheaper. Some parents may be worried that "steel teeth" will affect the appearance, but in fact metal materials are used for posterior teeth, which basically does not affect the appearance much. If the crowns are made of resin materials, the color is very close to the real teeth but less strong. It is only suitable for the front teeth with lighter bite force. Primary and permanent teeth are restored differently, and which crown material to choose depends on the tooth’s remaining lifespan.
Basically, crown for primary tooth will be completed in the clinical treatment time, but the clinical time for making them is actually longer than that of permanent tooth crown. The process of making permanent tooth crown is to grind down the tooth, then do impression, and then send it to dental laboratory for further procedures. Primary tooth crown saves the time for making it in the dental laboratory, but the doctor directly completes it in the clinic, which are two different approaches with that of permane
