There are a couple of options to rebuilt teeth affected by decay or a trauma. Small cavities could be filled with a dental composite material (a filling material the same colour as the tooth). For more destroyed teeth, or for those in some cases, that have a root canal treatment, a ceramic restauration (onlay, crown) could be appropriate to offer a better protection and to restore appearance and function. In some cases where there is tooth loss dental bridge, implants and dentures could be considered.
