What is Fill?

A filling is a method of restoring normal function and appearance to a tooth damaged by caries. When your dentist fills you, he first removes the decayed tooth tissue. It cleans the affected area and fills the cavity with filling material.

It also tries to prevent the progression of caries by closing the gaps that bacteria can enter with a filling. Materials used for filling, gold, porcelain, composite resin (tooth-colored filling)and amalgam. (an alloy of mercury silver, copper, tin, and sometimes zinc).


What is the Best Fill Type?

The same type of filling may not be suitable for everyone. The correct type of filling for you will be determined by the size of the cavity, your allergies to certain substances, the place where the filling should be done, and the cost. Considerations for different material types:


  • gold fillings It is made to order in the laboratory and applied by sticking it in place. Gold inlays have good tolerance to gum disease and can be used for more than 20 years. For these reasons, many authorities consider gold to be the best filling material. However, it is the most expensive choice and is applied in multiple sessions.
  • Amalgam (silver) fillings is resistant to wear and relatively inexpensive. However, due to their dark color, they are more noticeable than porcelain or other composite restorations and are generally not suitable for visible areas such as anterior teeth.
  • composite resin is the same color as your tooth and is therefore used when a natural look is desired. The materials are mixed and placed directly into the cavity where they are left to harden. Composite may not be an ideal material for large fillings as it can break and wear off over time. Also, it may become stained by tea, coffee or tobacco and do not last as long as other types of fillings, generally being used for three to 10 years.
  • Porcelain fillings called inlays or onlays It is manufactured to order in the laboratory and subsequently bonded to the tooth. It can be produced in accordance with the tooth color and is resistant to staining. Porcelain restoration generally covers most of the tooth. The cost is close to gold.

If the fracture or decay has damaged a large part of the tooth, a crown or veneer may be recommended. The bruise reaching the nerve can be treated in two ways: root canal treatment (the damaged nerve is removed)or a procedure called pulp capping (done to keep the nerve alive).

How Is Filling Made?

When your dentist decides to fill, he or she will first remove the carious tissue and then clean the other affected areas. The cleared space will then be filled with one of the materials described above.

How do I know if I need filler?

Your dentist can determine whether your caries needs to be filled. During a dental exam, your dentist uses a small mirror to examine each tooth surface.

Anything that looks abnormal is closely checked with a special device. Your dentist may also want to take an X-ray of part of your mouth. The type of treatment your dentist chooses will depend on the extent of the damage caused by the decay.
