Dental Fillings

We at Somani Family Dentistry Simi Valley provide cost effective Dental Fillings. The dental fillings are restorative material used to restore the function, integrity, and morphology of tooth structure lost to bacterial decay and/or external trauma. The two major materials used in dentistry for fillings are
1. Amalgam (silver)
2. Composite (white fillings)

-Amalgam Fillings is composed of silver, tin, copper, zinc, and mercury.
-Composite Fillings also known as White Fillings are synthetic resins most commonly composed of Bis-GMA monomers and filler materials such as silica.

Dental Filling Procedure

In our office if a patient is diagnosed with a cavity, the decay caused by bacteria is first removed. Once all of it has been removed if the tooth can be restored to full function and esthetics with a good prognosis the tooth structure lost to decay is filled with either amalgam or composite.
Which filling material to use is largely dependent on a patient’s preference as both materials have been proven to be very effective over many years.
Composite Fillings are typically a bit more expensive than amalgam but are also significantly more esthetic.


Inlays and Onlays can sometimes be used as alternatives to typical dental fillings. They are preferred for larger cavities as well depend on surrounding teeth structure They are made from either porcelain, gold, and/or composite or ceramic resin.
Inlays and Onlays are indirectly fabricated restorations and thus typically are not completed in one appointment; they require two appointments.
In the first appointment, as with fillings, decay and/or old fillings are removed, the tooth is prepared for an inlay/onlay, and an impression is taken which is sent to the dental technician at the laboratory.
The inlay/onlay will be cemented in the patient’s mouth at the second visit; in the interim a temporary sealant is placed on the prepared tooth or teeth.

Advantages of Inlay/Onlay over Regular Dental Fillings

So what are the advantages to choose an inlay/onlay instead of a regular filling?
– They are highly esthetic, no metal shows
– They are very strong once bonded to the tooth. The seal is very good (thus significantly lower chances of marginal leakage compared to regular fillings),
– They will not stain, insulate the teeth well, well suited for large cavities (more conservative than entire crowns/caps), and are long lasting.
However, they do have a few disadvantages: more expensive than regular fillings, can fracture, and they take two appointments.
