Tooth-colored fillings or composite fillings or “bonding” is our most common filling material. Composite resins are a great material to help fill or restore cavities. They are blended with your existing tooth shade so they help achieve a natural or aesthetic look.
An advantage, besides looking natural, composite fillings are chemically bonded to a tooth, so they can potentially help prevent breakage.
A disadvantage is staining. Composite fillings, like teeth can stain from pigmented foods and drinks.
Like any filling, there is a limit to how big in size a composite filling can be placed without compromising the tooth. If a filling is too large, the tooth is more at risk for breaking. In those circumstances, a crown or an onlay may be a better option.
