Types of Tooth Fillings

A dental filling is often used in dentistry to restore a damaged or decayed tooth. Patients may be surprised to hear they need a filling, but rest assured, it is an effective and safe procedure. A majority of patients will receive a filling during their lives. The filling works by restoring the tooth’s function and appearance while preventing additional damage.

Filling Type

Patients may be surprised to learn that there are actually different types of fillings available. The best treatment option depends on the patient’s individual case. Things such as the location of the damaged tooth, the severity of damage, allergies, and budget can all impact which type of filling best meets the needs of the patient. A summary of the most common types of fillings is outlined below:

  1. Amalgam – an amalgam filling is commonly used and is silver in color. Because amalgam is relatively affordable and strong, it is a popular solution. Unfortunately, because the material has a dark, visible color, it is not ideal for the front teeth, which are visible when smiling.
  2. Composite resin – a composite resin filling is white and has a more natural appearance. Unfortunately, the composite filling is easily stained and is not as durable compared to other materials. Dentists typically opt to use composite fillings for smaller cavities located in visible areas of the mouth.
  3. Gold – a gold filling is made for the individual patient. The dentist will cement it in place over the decayed tooth. Gold inlays are incredibly durable and strong. A gold filling, which is properly cared for, can last for 20 years or more. This filling costs the most and requires multiple visits to the dentist.
  4. Porcelain – a porcelain filling is made in a lab for the individual patient. Once available, the filling is bonded to the tooth. A benefit of porcelain is that it is stain-resistant and can closely match natural teeth. This restoration covers the entire tooth. It is more expensive than an amalgam or composite filling.

Filling Procedure

The dentist will begin by administering a local anesthetic to numb the treatment area. A handheld drill breaks through the enamel of the tooth to remove decay. A base layer can be placed to protect the tooth’s sensitive pulp. The filling is then placed.

When using a bonded filling, such as composite, the dentist will apply an acid gel to etch the tooth’s surface. This creates small holes in the enamel, allowing for the composite material to bond to the tooth. This reduces the risk of decay occurring below the filling. The dental professional will then use a special light to harden and cure the filling.

Upon the placement of the filling, the tooth is polished to smooth out any sharp edges or ridges on the tooth. Patients are also asked to bite down, which helps ensure the filling does not negatively impact how the teeth fit together. A special paper can be used to mark any raised parts of the filling, as the mouth may still be numb. Patients may need to return for adjustments if they become noticeable after the anesthesia wears off.
