Dental Crowns are custom-fitted tooth prosthetics that are used to restore fractured teeth. They improve the shape, size, and appearance of teeth.
The most common instances when a crown may be advised include:
- Fractured teeth
- Extensive decay that compromises tooth structure
- Root canal treated teeth
- Teeth that are extremely sensitive
- When esthetic improvements are required
What are Crowns Made out of?
Crowns can be made from different types of materials. Common permanent dental crowns are made of metal, porcelain fused to metal, ceramic, or resin. Temporary crowns tend to be made of acrylic or stainless steel.
Porcelain, or zirconia, are tooth-colored crowns that provide both improved aesthetics and enhanced function. Porcelain is also a stronger material. Porcelain requires minimal tooth preparation, hence preserving natural tooth structure. They are usually the restoration of choice when restoring back teeth which have higher chewing forces.
Porcelain Fused to Metal
A PFM crown has a layer of precious metal underneath the porcelain. They present several disadvantages compared to a zirconia crown. The metal underneath the porcelain shows in the form of unsightly grey lines at the gums, causing them to look less cosmetic. They require more tooth structure to be removed to account for a layer of metal. This makes the gums more vulnerable to decay and inflammation with metal allergies. At times, the Porcelain over the metal may fracture or chip from the metal exposing the metal underneath.
An e-max crown is the restoration of choice when replacing anterior or front teeth. E-max provides excellent aesthetics, improved function, and resemblance of natural teeth. They also require minimal tooth preparation and therefore, look less bulky.
The procedure involves building up the tooth after removing any existing decay or fragile tooth margins followed by an overall reduction of tooth based on the type of material used. We then make an impression or mold of the prepared tooth for a more customized fit of the final prosthesis. A temporary restoration is placed on the tooth while you are waiting to receive the final permanent crown. The temporary preserves the gum and tooth area and prevent any sensitivity around the tooth.
Caring for Your Crowns
Caring and maintaining the permanent dental crown is similar to that of your natural teeth. Brushing and flossing in between meals will help keep your crown plaque-free and will increase the longevity of the crown and the tooth. A night guard is a great preventative way to protect the crown against fractures, especially if you grind your teeth.
However, with a temporary crown, avoid sticky, chewy, and hard foods. It’s recommended to avoid chewing on the side of the mouth with the crown. Lastly, when flossing, don’t lift out but slide dental floss when taking care of your daily hygiene. Keeping these in mind, the temporary crown should stick around until your permanent crown is placed.
