Cavity fillings, also known as dental fillings, are used to repair teeth damaged by decay. Understanding what they look like can help alleviate anxiety and ensure you know what to expect from your dental treatment. The appearance of a filling can vary greatly depending on several factors, including the size and location of the cavity, the material used for the filling, and the skill of the dentist.
What Materials Are Used for Fillings and How Do They Look?
Several materials are commonly used for dental fillings, each with its own distinct look and feel:
-
Amalgam (Silver Fillings): These are the most recognizable type of filling, often appearing as a silvery-grey metallic color. They're durable and relatively inexpensive, but some patients prefer tooth-colored options for aesthetic reasons. Amalgam fillings tend to be more visible, especially on the front teeth.
-
Composite (Tooth-Colored Fillings): These fillings are designed to blend seamlessly with the natural color of your teeth. They're made from a resin material that is cured with a light, matching the shade of your surrounding enamel. They can sometimes appear slightly glossier or more opaque than your natural teeth, but generally, they're quite inconspicuous.
-
Gold Fillings: Gold fillings are known for their exceptional durability and longevity. However, they're significantly more expensive than other options and are generally reserved for larger restorations. Their characteristic golden color makes them easily identifiable.
-
Ceramic Fillings (Porcelain): Similar to composite fillings in their aesthetic appeal, ceramic fillings are also tooth-colored and can blend in very well. They are incredibly durable, and mimic the translucency of natural teeth very well.
How Big Are Fillings, and How Are They Placed?
The size and placement of a filling depend entirely on the extent of the tooth decay. Small cavities may only require a small filling, while larger cavities could need more extensive restoration. Your dentist will prepare the affected tooth by removing the decayed portion before placing the filling material. The filling is then shaped, smoothed, and polished to match the surrounding tooth structure.
How Long Do Fillings Last?
The lifespan of a filling depends on several factors, including the type of filling material used, the location of the filling, and your oral hygiene habits. Amalgam fillings tend to last longer than composite fillings, but both are relatively long-lasting with proper care. Regular dental checkups and good oral hygiene are crucial to extending the life of your fillings.
Do Fillings Feel Different?
Immediately after placement, a filling might feel slightly different, possibly slightly higher than the surrounding teeth. However, this is usually temporary. Your dentist will ensure the filling is properly shaped and contoured to prevent any discomfort or interference with your bite. Over time, you should barely notice the filling.
Can Fillings Be Replaced?
Yes, fillings can eventually wear down or become damaged and require replacement. Regular dental checkups are important to monitor the condition of your fillings and address any issues before they become major problems.
What are the signs of a failing filling?
Keep an eye out for signs that your filling needs replacing including: pain when biting down, sensitivity to hot or cold temperatures, visible cracks in the filling, or a change in the color or appearance of the filling.
