A Quick Introduction to Different Types of Fillings

It started with some discomfort that progressed to pain. The next thing you know the dentist is saying that a cavity has developed and that a filling is needed to repair the damage and prevent it from worsening. This is where the decision making process starts, as there are different types of fillings to choose from.

Silver Amalgam

Silver amalgam is a pretty common type of filling. It’s made from silver, tin, mercury, copper, and zinc. While mercury is poisonous, silver amalgam has been declared safe for use, so you shouldn’t need to worry about mercury poisoning from this filling. It’s strong and sturdy, and tends to be less expensive than other options. That said, it isn’t the most aesthetic filling, so it’s most commonly applied to the molars rather than the front teeth. It’s also important to note that silver amalgam does sometimes expand and contract, which can lead to the filling loosening or even cracking the tooth.

Gold

Like silver amalgam, gold fillings are quite strong and can last for some time if taken care of properly. They’re also non-corrosive, though they are relatively expensive. Gold fillings can’t mimic the natural appearance of the tooth, so you may be more likely to have these done in the back teeth as well. You’ll probably need more than one appointment to have them fitted properly.

Composite Resin

Metal fillings don’t look like natural teeth, but composite resin fillings sure can. While not as durable as silver, and usually more expensive, they’ll still last 5-10 years. Composite resin fillings are a better option for front teeth that are visible because they can be made to closely match the rest of the tooth.

Ceramic

If the composite resin fillings have you feeling a little concerned about durability, ceramic fillings may be a better option for visible front teeth. Like composite resin, ceramic fillings are tooth colored. They tend to be more stain and abrasion resistant, though the catch is that they are often more expensive. Ceramic can also be brittle, which means that they’re best used for larger fillings to reduce the risk of them breaking.

The different types of fillings each have their own sets of pros and cons. Which one should be used on any given cavity will depend on the location of the cavity along with some personal circumstances.
