Dental Fillings
Dental fillings are restorations used to repair minor to moderate tooth damage, typically due to decay (cavities), minor fractures, or wear. When bacteria in the mouth produce acids that erode tooth enamel, this decay creates holes in the teeth that can worsen over time if untreated. Fillings help stop this process by sealing off the area, restoring the tooth’s shape and function, and preventing further decay or infection.
Why are Dental Fillings Necessary?
When left untreated, tooth decay can lead to pain, sensitivity, and more extensive dental issues, such as infections or abscesses. If decay spreads deep into the tooth, a filing may no longer be sufficient, and more involved procedures like root canals or extractions, could be necessary.
Fillings protect the tooth structure, maintain functionality, and provide long-term benefits by reinforcing the tooth against further damage.
The Dental Filling Procedure
The process for placing a dental filling is relatively straightforward.
- Examination and Preparation: One of our dentists begins by examining the decayed or damaged area, often using x-rays to gauge the extent of the decay. Once determined, we may or may not have to utilize a local anesthetic to numb the area.
- Decay Removal: The decayed part of the tooth is removed, typically using a drill. This step is crucial to prevent further decay beneath the filling and to prepare the tooth for bonding.
- Cavity Preparation: Your dentist will shape the cavity to allow for a secure filling. For composite fillings, an etching gel may be applied to help bond the material to the tooth.
- Placing the Filling Material: The chosen filling material is applied in layers, especially if using composite resin. Each layer is hardened with a special light to secure it before the next one is added.
- Shaping and Polishing: Once the filling is set, your dentist shapes and smooths it to ensure it blends seamlessly with the tooth and won’t interfere with your bite.
When to Replace a Dental Filling
Fillings don’t last forever and may need replacement due to wear, damage, or new decay around the filling. Signs that a filling may need replacement include sensitivity to temperature, visible wear, or cracks. Regular dental checkups are essential for monitoring the condition of fillings and catching potential problems early.
