How Does a Dental Crown Work?

A Robina Dental crown is a tooth-shaped cap that is placed over a damaged or decayed tooth. It restores the shape, size, strength and improves the appearance of a tooth. A crown may be needed to save a tooth that has been severely damaged by decay, or to protect a tooth that has been treated with a root canal.

The process of getting a dental crown starts with the dentist numbing the affected area of the tooth and gums, then removing all decay. Next, the dentist prepares the tooth for the crown by reducing the size of the chewing surface and removing as much of the remaining core (the layer underneath) as possible to create space for the crown.

Once the tooth has been prepared, the dentist takes an impression of the prepared tooth with a putty-like material that is similar to polyvinyl siloxane (PVS). The impression is sent to the dental laboratory for use in creating your dental crown.

There are many different types of dental crowns, which can be created using a variety of materials depending on the clinical situation as well as the patient’s budget and preferences. Some crowns are made from porcelain, which is a strong and tooth-like material that can mimic the natural color of the tooth, while others are made from metals like gold, silver or even base metals.

Porcelain crowns are generally used in the upper teeth, as they offer a very natural looking colour. They are also more stain resistant than metals, making them an excellent choice for people with a high level of food or drink staining on their teeth.

In the case of a dental crown, it’s important to get an accurate impression as even the smallest flaw in an impression can result in a crown that doesn’t fit properly.

During the impression process, your dentist will fill a tray with the correct acrylic resin material to match the colour of your natural teeth. Once the dentist has placed the tray in your mouth, they will then bite down on it to ensure that the impression material is fully set and firmly stuck to your teeth.

This process is done several times until the final impression is very precise. Then the dentist will remove the tray from your mouth and examine it to make sure there are no air bubbles or voids in the impression.

Once the impression is complete, the dentist will place a rubber dam over the teeth involved in the procedure to keep the old filling material and tooth structure from falling into the mouth.

The next step in the procedure is to numb the surrounding gum tissue with an injection of a local anesthetic. This is necessary to ensure that the patient doesn’t experience any pain during the procedure.

Your dentist then uses a gingival retraction cord to gently push your gums away from the edges of the prepared tooth. Once the tooth has been numb, your dentist will begin preparing it for the crown by removing all decay and shaping it to make room for the crown.
