Restorative dentistry has come a long way. In the past, dental fillings were traditionally made out of metal amalgam, but nowadays many dentists prefer tooth-colored fillings composed of natural-looking composite resin. Do you have an older metal amalgam filling? It could be in your best interest to trade it out for a tooth-colored filling; here are just 3 reasons why.
1. Metal Fillings Often Contain Mercury
The amalgam used for dental fillings is often half mercury and half other metals. Over time, the mercury in your fillings can be released as vapor and absorbed into the body. One study found that individuals with more than eight metal fillings had 150% more mercury in their blood compared to individuals with no fillings. These findings are concerning, as exposure to mercury can lead to various health issues.
Meanwhile, tooth-colored fillings do not contain any mercury. This can make them a safer choice for your overall well-being.
2. Metal Fillings Can Damage Your Teeth
Metal amalgam fillings slightly expand when exposed to hot temperatures, and they slightly contract in response to cold temperatures. Over time, these size changes can end up damaging your teeth, which is the last thing you want if you’ve already needed to have a filling placed.
In contrast, a tooth-colored filling will not expand and contract due to temperature changes. As such, replacing a metal filling with a tooth-colored one could help you protect your tooth in the long term.
3. Metal Fillings Stand Out
One of the most obvious downsides of metal amalgam fillings is that they are very noticeable. The dark-colored metal tends to stand out from the rest of your smile. As a result, your fillings can end up drawing attention to your teeth for all the wrong reasons.
A tooth-colored filling can be shaded and sculpted to closely resemble your enamel. The result is a highly natural-looking restoration that blends right in with the rest of the tooth structure. Most people meeting you for the first time are unlikely to realize that you have had dental work performed and will only take note of your dazzling, natural-looking smile.
There are plenty of reasons why replacing a metal filling can be an excellent decision. That said, you will need your dentist’s help to determine whether this is truly the best option for you. After they have examined your current restoration and considered your unique situation, they can help you figure out the best steps to take to protect your oral health.
