Fillings
Dental restorations, commonly known as fillings, have traditionally been made of silver amalgam. This material’s strength and durability make it particularly suitable for posterior teeth that endure significant chewing forces. However, modern dentistry offers a range of alternative materials that combine functionality with aesthetics.
Contemporary dental fillings include ceramic and plastic compounds, known as composite resins, which closely mimic the appearance of natural teeth. These materials are frequently used for anterior teeth where aesthetics are paramount, but can also be applied to posterior teeth depending on the extent and location of the decay.
Selecting the Optimal Dental Filling
The selection of an appropriate dental filling depends on several factors that influence its performance, durability, longevity, and cost:
– Composition of the filling material
– Remaining tooth structure
– Placement technique and location
– Anticipated occlusal forces
– Number & duration of appointments required for preparation and adjustment
Prior to treatment, your dental practitioner will discuss all available options and assist you in choosing the most suitable filling for your specific case. To facilitate this discussion, it’s beneficial to understand the two primary categories of dental fillings: direct and indirect.
– Direct Fillings are placed into a prepared cavity during a single appointment. These include silver amalgam, glass ionomers, resin ionomers, and composite (resin) fillings. The dentist prepares the tooth, places the filling, and makes necessary adjustments in one visit.
– Indirect Fillings typically require multiple appointments. This category encompasses inlays, onlays, and veneers fabricated from materials such as gold, base metal alloys, ceramics, or composites. These are utilized when a tooth has sustained too much damage to support a direct filling but not enough to necessitate a full crown. The initial visit involves tooth preparation and impression-taking, followed by placement of a temporary covering. The impression is then sent to a dental laboratory for fabrication of the restoration. During a subsequent appointment, the dentist permanently cements the restoration and makes any required adjustments.
