Dental Fillings
Restorations are required when a tooth develops decay (cavity). Decay will continue to spread over the tooth surfaces if it is not removed, left untreated it will become worse and eventually it may cause the tooth to weaken, break and/or an abscess to form. If the tooth reaches this state you will most likely require a root canal. This is why it is important to treat a cavity as soon as possible, meaning before it starts to bother you.
