Amalgam fillings are no longer your only option — now there are also white fillings. London Ontario, patients who already have amalgam fillings often want to know if they should replace their current fillings with white ones. Whereas this is not always necessary, it does have some advantages.
The Difference Between Amalgam and White Fillings
Amalgam fillings are made from a combination of metals. The result is a silver-coloured alloy strong enough to withstand biting forces. The main problem is aesthetics, especially since, over time, the fillings can stain teeth grey. Another issue is that they can expand and contract when exposed to hot and cold temperatures, which can lead to cracks in teeth.
White fillings are made from porcelain or composite resin. Porcelain is an even stronger material than amalgam, whereas composite resin fillings have a shorter lifespan. Both types of white fillings match the colour of your teeth exactly and will not damage your teeth. Plus, porcelain is resistant to stains.
Why Replace Amalgam Fillings?
There is no reason to be concerned about health risks from amalgam fillings. Although they do contain mercury, the small quantity is completely safe. However, there are several other reasons why you may like to consider replacing them with white fillings.
If your filling is near the front of your mouth, it may be visible when you speak. Changing it for a white filling will improve appearances.
Another reason could that you need to replace the filling anyway. For instance, if your tooth is cracked, it may no longer support the filling. The same goes for a decay or a gap between the filling and the tooth — the second of which can happen if you grind your teeth.
Book a consultation with a dentist at our London dental clinic to discuss replacing your amalgam fillings with white ones.
