Composite Resin:
Used for: Small and large fillings, especially in front teeth or the visible parts of teeth.
Your fillings or inlay will be invisible. Your dentist    chooses a resin that matches the color of your    teeth.
A filling can be completed during one dental visit.
Composite fillings can bond directly to the tooth,    making the tooth stronger than it would be with an    amalgam filling.
Less drilling is involved than with amalgam fillings .
The bonding process holds the composite resin
   in the tooth.
Composite resin can be combined with glass
   ionomer to provide the benefits of both materials.
Glass Ionomer:
Used for: As filling material, glass ionomer is typically used in people with a lot of decay in the part of the tooth that extends below the gum (root caries). It is also used for filling baby teeth and as a liner for other types of fillings.
  Glass ionomer matches the color of the teeth,     although it does not always match as precisely     as composite resin. Resin-modified glass     ionomer is usually a  better match than     traditional glass ionomer.
  In some cases, no drilling is required to place a     glass ionomer filling. This makes this type of     filling useful for small children.
 Glass ionomers release fluoride, which can     help protect the tooth from further decay.
 Glass ionomer restorations bond to the tooth,     helping prevent leakage around the filling and     further decay.
Traditional glass ionomer is significantly weaker than composite resin. It is much more    susceptible to wear and prone to fracture.
Traditional glass ionomer does not match your tooth color as precisely as composite resin.
If you are receiving a resin-modified glass ionomer filling, each thin layer needs to be    cured, or hardened, with an ultraviolet light before the next layer can be added. This    makes the tooth stronger, but can lengthen the time of the dental  appointment.
