Natural Restorations/Fillings

Traditional dental restoratives, or fillings, are most often made of silver amalgam. The strength and durability of this traditional dental material makes it useful for situations where restored teeth must withstand extreme forces that result from chewing, often in the back of the mouth.  However, over time amalgams cause fractures in natural teeth due to differences in its physical properties with particular note to thermo-expansion. 

Newer dental fillings include ceramic and resin compounds that mimic the appearance of natural teeth. These compounds, often called composite resins, are usually used on the front teeth where a natural appearance is important, but they can also be used on the back teeth depending on the location and extent of the tooth decay.  New materials such as Ivoclar's Tetric Evo Ceram will mimic the properties of natural tooth structure and has the added benefit of bonding the teeth together for an additional layer of protection from heavy forces.  

What’s right for me?

Several factors influence the performance, durability, longevity, and expense of dental restorations, including:

  • The components used in the filling material
  • The amount of tooth structure remaining
  • Where and how the filling is placed
  • The chewing load that the tooth will have to bear
  • The length and number of visits needed to prepare and adjust the restored tooth

Before your treatment begins, your doctor will discuss with you all of your options and help you choose the best restorative material for your particular case. In preparation for this discussion it may be helpful to understand the two basic types of dental fillings — direct and indirect.

  • Direct fillings are fillings placed into a prepared cavity in a single visit. They include silver amalgam, glass ionomers, resin ionomers, and composite (resin) fillings. The dentist prepares the tooth, places the filling, and adjusts it in one appointment.
  • Indirect fillings generally require two or more visits. They include inlays, onlays, and veneers fabricated with gold, base metal alloys, ceramics, or composites. They are used when a tooth has too much damage to support a filling but not enough to necessitate a crown. During the first visit, the dentist prepares the tooth and makes an impression of the area to be restored. The dentist then places a temporary covering over the prepared tooth. The impression is sent to a dental laboratory, which creates the dental restoration. At the next appointment, the dentist cements the restoration into the prepared cavity and adjusts it as needed.
