A dental crown, also known as a cap, is a tooth-shaped covering that encases a damaged or weakened tooth to restore its shape, size, strength, and appearance. Understanding what a crown looks like involves considering both its material and how it integrates with the natural tooth.
What Materials Are Dental Crowns Made Of?
The appearance of a dental crown is heavily influenced by the material used. Common materials include:
-
Porcelain: This is a popular choice because it's highly aesthetic, closely mimicking the natural color and translucency of teeth. Porcelain crowns are strong and durable, resisting staining well. They typically look very natural, blending seamlessly with surrounding teeth.
-
Ceramic: Similar to porcelain, ceramic crowns offer excellent aesthetics and are biocompatible (meaning they're compatible with the body's tissues). They are also very strong and resistant to wear.
-
Metal: Historically, metal crowns (gold, alloys) were common due to their exceptional strength and durability. While less aesthetically pleasing, they are still used in situations where strength is paramount, such as on back molars. They are typically noticeable due to their metallic sheen.
-
Porcelain-Fused-to-Metal (PFM): This type combines the strength of a metal base with the aesthetic appeal of a porcelain outer layer. The metal core provides strength, while the porcelain veneer gives a natural appearance. However, a thin line of metal may sometimes be visible at the gum line.
What Does a Crown Look Like Once It's Placed?
Once cemented onto the tooth, a crown should look completely natural and integrated. You should not be able to easily distinguish it from your natural teeth. A well-placed crown:
- Matches the surrounding teeth in color and shape: A skilled dentist will select a shade that precisely matches your existing teeth to ensure a seamless blend. The crown's shape will also be meticulously crafted to fit naturally within your smile.
- Restores the original size and shape of the tooth: If the tooth was broken or severely worn down, the crown will restore it to its original form, improving its functionality and aesthetics.
- Has a smooth, polished surface: A properly fitted crown will have a smooth surface, preventing food particles from getting trapped and minimizing irritation to the gums.
- Is securely cemented: A properly cemented crown should feel firmly attached and shouldn't move or wiggle.
How Does a Crown Differ from a Filling?
A crown completely covers the visible portion of the tooth, while a filling only repairs a damaged area within the tooth. A filling is usually less noticeable than a crown, often blending more seamlessly with the surrounding tooth structure. Crowns are used when a tooth has extensive damage that a filling can't repair.
What if My Crown Doesn't Look Natural?
If your crown doesn't look natural, several factors could be at play:
- Poor color match: The shade of the crown might not perfectly match your existing teeth.
- Improper shaping: The crown's shape or contour might not be natural-looking.
- Poor cementation: If the crown is not properly cemented, it might appear slightly raised or loose.
It's crucial to contact your dentist if you have any concerns about the appearance or fit of your crown. They can assess the situation and determine the necessary steps to address any issues. This could involve adjustments, replacement, or other restorative measures.
Can I Choose the Material for My Crown?
Yes, you can discuss material options with your dentist. They will help you choose the best material based on your individual needs, considering factors like the tooth's location, the extent of the damage, your budget, and your aesthetic preferences. Your dentist will also consider the long-term durability and longevity of each material.
Remember, the appearance of a dental crown should be a collaborative effort between you and your dentist. Open communication is key to achieving a natural-looking and functional restoration.
