White Fillings


What Are White Fillings?

White fillings are tooth-colored fillings that are made of a mixture of resin and glass. Like silver fillings have done for the past 100-plus years, tooth-coloured fillings repair broken or decayed teeth. This alternative to silver fillings involves bonding techniques that result in strong margins and long-lasting structural support.
In the past, dental cavities were filled with a mixture of metal alloys, known as amalgam. Today, there are two types of white fillings in dentistry: Resin Restorations & Porcelain Onlays.

Which Type Of Filling Is Best For Me?

We proudly offer two white filling options: resin fillings and porcelain restorations. When deciding which type of filling is best, it is necessary to evaluate all the advantages and disadvantages of each choice. White fillings are known for being slightly more expensive than silver fillings. However, many patients prefer the natural look and feel of white fillings versus the less-expensive option. Patients receive detailed information about their filling options and how they compare to silver fillings to help them make the most educated and confident decision for themselves.


Resin Restorations In Posterior (Back Teeth)

This filling is the replacement for the old silver fillings or amalgam. Resin restorations are bonded to the tooth to provide a seal between the tooth and restoration. Many shades are now available; therefore, when you open your mouth, no one should know that you have any fillings at all. The technique we use for placement reduces the possibility of post treatment sensitivity. As with all direct restorations, if they are too large, an alternative is needed.


Porcelain Onlays

When the restoration in a posterior tooth is too large, this is the best solution. An onlay covers the functional parts (the top) of the tooth. It is as strong as a crown but much less invasive. The porcelain colour blends with the colour of the natural tooth. An onlay is a long lasting cosmetic restoration, much like a crown.


What Are The Benefits of White Fillings over Silver Fillings?

Many people find white fillings an appealing option for restorative care. Understandably, fillings that are matched to surrounding enamel have no effect on the appearance of the smile, whereas silver fillings turn dark over time. Because of the natural appearance of white fillings, this treatment option is preferred for teeth that are visible in the smile. However, appearance is not the only advantage of tooth-coloured fillings.
With careful bonding techniques, white fillings adhere nicely to teeth. The bonding process of these fillings is much different than silver fillings. Because silver fillings are made with metal, they cannot bond to enamel. These fillings must be held in place mechanically, which means the dentist has to carve the tooth precisely so that the filling material will be surrounded. Mechanical retention of the silver filling requires more extensive drilling of the tooth than is necessary for a white filling.
Another advantage of white fillings is that the materials that are used, resin or porcelain, are not likely to corrode over time the same way metals do. Resin and porcelain also do not expand and shrink the same way that metals do. Over time, the expanding and contracting that occur with silver fillings can degrade the margins of the restoration or cause fractures in the tooth.

How Long Does White Filling Placement Take?

Most white fillings can be placed in a single visit unless the patient needs an inlay, onlay, or crown. Standard white fillings are placed one layer at a time, with drying in between. This achieves the strongest possible bond between the resin or porcelain and tooth enamel. A white filling may take longer on average than a silver filling but may still be completed within an hour to 90 minutes.

Can White Fillings Become Stained?

White fillings that are made with composite resin are susceptible to staining over time. Like natural enamel, resin can absorb tiny particles of consumed substances such as red wine, coffee, tea, cola, and tobacco. Superficial stains may be filed down. In more severe cases, a stained filling may be touched up with a layer of resin or replaced.

Can I Have Silver Fillings Replaced With White Fillings?

Patients whose silver fillings have eroded, fractured, or degraded in some way can have these restorations replaced with tooth-colored fillings, onlays, or crowns. Some people choose to replace silver fillings with white fillings because they do not like the appearance of the visible filling or because they are concerned with the potential effects of the mercury that is contained in silver fillings.

Are Tooth-Coloured Fillings Safe?

Tooth-coloured fillings have a history of safety and efficacy. The materials that are used today are strong, non-allergic, and able to withstand normal biting force.
