White Fillings

15th August 2023

Dental fillings are essential for the restoration of teeth affected by cavities. They serve to “fill” the damaged or decayed portions of a tooth, effectively restoring its structure and function. Various materials are available for fillings, including traditional amalgam and more aesthetically pleasing options such as composite resin and porcelain. The longevity of these fillings can vary significantly based on the material chosen, with some types capable of enduring for as long as two decades.

What are white fillings?

Composite fillings, commonly referred to as white fillings, consist of a blend of resin, glass, and occasionally ceramic or porcelain. The components include:

• Resin: A tooth-coloured plastic material.
• Glass: Finely milled glass or ceramic particles.

White fillings are favoured for their ability to be tinted to match the natural colour of your teeth, rendering them nearly undetectable. They serve both to repair cavities and to enhance the aesthetic appeal of your smile.

In contrast to silver amalgam fillings, which are composed of various metals such as silver, tin, copper, and mercury, white fillings offer a more discreet option.

What happens during a dental filling procedure?

The specific process for your fitting will vary based on your individual situation, the extent of the damage, and the location requiring a filling. However, we can provide you with general information about the typical steps involved in the filling procedure.

Local anaesthetic

While some fillings can be done without anaesthetic, most procedures will involve the use of a local anaesthetic. Advances in techniques have made the administration of this numbing agent more comfortable than in the past.

Removal of decayed material

In addition to surface cavities, decaying material within the tooth may need to be addressed. This material must be removed before the filling can be applied; otherwise, it could lead to complications beneath the filling. This step is generally quick, though it may produce a buzzing sound and some vibrations.

Area preparation

The preparation process will depend on the type of filling being used. Your dentist may need to etch the surface to enhance bonding. Once the area is adequately prepared, the filling will be placed.

Resin application and polishing

There are various methods to achieve a polished finish for the procedure. Your dentist may apply a resin for added strength and then polish the tooth for a smooth final appearance. Once the white filling is in place, it will be difficult for anyone to notice that any repairs have been made, which is the hallmark of an effective restorative treatment.
