Replacing Silver Dental Fillings With Tooth-Colored Ones
If you have silver dental fillings, you might want to replace them with tooth-colored restorations. Tooth-colored fillings, also called composite resin, are a popular choice these days, and you can get the replacement at your dentist. Your dentist will remove the silver fillings and then fill the hole with composite resin. Learn some of the reasons people choose to replace silver amalgam fillings.
Reasons to replace silver dental fillings
Silver amalgam fillings are made from a combination of metals. The fillings usually include copper, tin and mercury, and indium, palladium or zinc might be added as well. In the past, dentists usually used silver amalgam when filling teeth, but composite resin is on the rise. This has caused many people to choose to remove the silver fillings in favor of composite resin.
Limited life span
Most fillings have to be replaced eventually. The restoration lasts for years but is not permanent. In the case of silver amalgam, the fillings usually last for 10-15 years. Once the filling begins to break down, bacteria can get under the silver amalgam material and cause cavities. Patients are encouraged to replace fillings when they begin to fail. Many choose tooth-colored entail fillings for the replacement.
Expands and contracts with temperature changes
Silver amalgam fillings are sensitive to temperature changes. The fillings expand and contract when exposed to temperatures. Drinking a hot beverage causes the filling to get bigger while eating ice causes it to shrink. Both can damage the tooth.
When a filling gets larger, it can crack the tooth. Small cracks are not always noticeable but can cause the tooth to split over time. When a filling gets smaller, it causes a gap that bacteria can enter. The constant changes in size can weaken the tooth over the years. Those who do not want to worry about this can replace silver amalgam fillings with tooth-colored dental fillings.
One of the biggest complaints about silver fillings has to do with the looks. Most people do not like the way the fillings stand out. Others can see the fillings when people laugh and talk. Composite resin fillings are matched to the existing teeth. The material blends in, so people do not see the fillings.
Does not bond with the tooth
To place silver fillings, the dentist drills a large hole in the tooth. The filling material is placed in the hole, much like filling a pothole. It does not bond with the tooth. However, composite resin fillings bond with the tooth. This strengthens the tooth.
Do you want to replace your dental fillings?
There are lots of reasons to replace your silver fillings with composite resin. Your silver fillings might be close to failure and need replacement. You might also choose to replace your fillings because silver expands and contracts or you might not like the appearance of silver fillings and want something that bonds to the teeth. Talk to your dentist to see if you are a good candidate to replace your fillings.
