There are many advantages to tooth-colored restorations. Composite resins are bonded to the teeth creating a tight, superior fit to the natural tooth. Such restorations can be used in instances where much of the tooth structure has been lost.
Since the resin used in tooth-colored restorations contains fluoride, this can help prevent decay. The resin wears much like natural teeth.
The result is a beautiful smile!
Dental Amalgam is a commonly used dental filling that has been used for over 150 years. Amalgam has many advantages over other restorative materials, such as strength, durability, and bacteriostatic effects.
Amalgam is used in dentistry for a number of reasons. It is relatively easy to use and manipulate during placement; it remains soft for a short time so it can be packed to fill any irregular volume, and then forms a hard compound. Amalgam possesses greater longevity than other direct restorative materials, such as composite. On average, most amalgam restorations serve for 10 to 12 years, whereas resin-based composites serve for about half that time.
The American Dental Association Council on Scientific Affairs has concluded that both amalgam and composite materials are considered safe and effective for tooth restoration.
