There is a range of materials that a filling can be made of. Your dentist will go through with you the different types and discuss with you’re the optimal filling material for your tooth.
The most common type of filling material used is Composite Resin which is the tooth-colored filling and is the current “Gold Standard” filling material that can be used in most situations. It is safe, strong and looks nice as well!
However, if a large portion of your tooth is lost or there are cracks around your tooth, your dentist may instead advise you to get a crown or cap. Please consult with the dentist first if your tooth is suitable or not for a filling or a crown.
