Choosing a filling material
One of the most common procedures that dentists perform is the repair of decayed teeth and the filling of cavities brought about by such decay. When it comes to this particular dental process, you will find that you actually have quite a few choices. These options bring with them various pros and cons, which you should know about before you make your decision regarding what type of tooth filling is preferred.
Amalgam
This is a filling which contains a combination of metals that include silver, tin and mercury.
While an amalgam filling is still one of the more inexpensive and more durable options available, it is still one of the types less-favoured by those who need fillings due to the fact that the metal darkens over time. The use of amalgam also requires the removal of parts of your tooth which are still healthy, in order for the filling to adhere properly.
Composite (white fillings)
This is the second most used filling, although it is fast becoming the top choice for many dentists as vast improvements have been made to the durability of the material. This particular type of filling is more natural-looking and does not require the dentist to remove as much of the healthy tooth for the filling to stick properly. This option does not corrode or darken like metal fillings, may be bonded to the tooth for added strength, and is ideal for smaller cavities.
Some disadvantages of white fillings are that they may not be strong enough to restore large cavities. They may also stain over time and can be quite difficult to place in some teeth, as they are sensitive to moisture.
Ceramic
For larger cavities, a milled ceramic inlay or onlay is often a better answer than a very large white filling. We make these here in one appointment — see CEREC one day restorations.
Gold
This is another option for dental fillings. As you may already know, this can be the most expensive option available and is only considered by those who want a very durable filling for their tooth. These restorations have to be made in a dental laboratory and require two visits. Gold restorations are tarnish-resistant and corrosion-resistant fillings. They are very strong but may be expensive. They are, however, not to everyone's taste with regard to their appearance.
Frequently asked questions
How much is a white filling in Peterborough?
Composite (white) fillings start from £120, amalgam from £90 and glass ionomer £130. A baby tooth filling is £45.
Should I replace my old amalgam fillings?
Not simply because they are metal. If an amalgam filling is sound, replacing it means removing more tooth. If it is failing, cracked or the tooth is breaking down around it, we will discuss replacing it — often with a ceramic restoration.
How long do white fillings last?
Modern composites are considerably more durable than they used to be. Lifespan depends on the size of the filling, where it sits in the bite and how well the tooth is cleaned.
