What is a dental crown and what are the indications for installation?
Dental crowns are caps or shells that cover damaged teeth. They restore shape, size, and strength, and are used to protect weak teeth, cover large fillings, or improve the appearance of discolored teeth. There are several types of crowns, including metal-ceramic, ceramic, and zirconia. The process involves preparing the tooth, taking an impression, and placing it in place.
More about types of dental crowns
Ceramic crowns come in several types, each designed to meet different aesthetic and functional needs. You can choose from several types of these crowns based on your preferences. There are two types of ceramic crowns:
- All-ceramic crowns. Made from ceramic materials, they provide the most natural appearance. They are often used in the smile zone, as they reflect and refract light like natural enamel.
- Ceramic crowns on a metal base. They combine metal for strength with a ceramic outer layer for aesthetics. They are often chosen for chewing teeth, where beauty is not important. However, such onlays will be somewhat darker and more matte than crowns made of ceramic only. For patients who are looking for a balance between reliability and price, metal-ceramic crowns are an excellent choice.
Zirconium crowns are a popular choice due to their super strength and natural appearance. They are made of a durable material – zirconium dioxide, which ensures their durability. Zirconium crowns are also almost 100% biocompatible. This means that they interact well with the tissues of your mouth. Zirconium crowns are as natural as ceramic ones, but stronger and more durable.
How is the installation done
The installation of a dental crown requires two visits to the dentist. The first visit includes the preparation of your natural tooth and the installation of a temporary crown. The procedure begins with an examination of the oral cavity and taking an impression of the teeth for the manufacturer of the onlay.
- Tooth preparation: the dentist removes damaged parts of the tooth, grinds it down if necessary. Also at this stage, caries is treated, if it is detected during the examination.
- Impression: an impression of the tooth is taken to create a custom crown.
- Temporary crown: a temporary acrylic crown is installed to protect the tooth.
- Second visit: the temporary crown is removed and the permanent crown is cemented.
Service life and care of crowns
A high-quality dental crown can last from 10 to 20 years with proper care. To extend the service life, it is necessary to adhere to regular care.
- Daily oral hygiene. Brush your teeth morning and night and floss daily to prevent plaque buildup.
- Preventative professional cleanings. Schedule professional cleanings and checkups every six months.
- Avoid bad habits. Don’t open packages or bottle caps with your teeth, don’t chew ice or very hard nuts, and don’t bite your nails.
- Use a night guard if you grind your teeth at night (bruxism) to protect your crowns.
