People having a cavity in their tooth need to visit a dentist. The dentist would remove the decay portion in their tooth. This would diminish the suffering of the patient. But, this is not the complete step. Filling needs to be placed at the removed decay portion. This method is used since a long time to restore a tooth.

There are some common kinds of fillings used by dentists. Let us explore them in detail:

1. Silver amalgam:

This filling material is popularly used by dentists all across the world. Amalgam comprises of a mixture of silver, zinc, tin, mercury and copper. Mercury is closely 50 % of this mixture. Amalgam is hugely popular among the dentists as it comes at a low cost. It is known for its good strength as well as durability. This material is not aesthetically pleasing but it usually survives for 15 years or even more. This says a lot about the long lastingness of this material. Such fillings can be easily placed in the tooth. There are no worries of contamination arising from blood or saliva.

There are some drawbacks of this material that you need to know. It is prone towards expansion as well as contraction. Due to this it can make your tooth crack. Such a fluctuation may build open spaces in between tooth and filling. This may cause the bacteria and food to get trapped to enable the forming of cavities. The presence of mercury in these fillings is also termed controversial.

2. Composite fillings :

This material is hugely popular due to its tooth-colored look that can match the existing shade of a person’s teeth. The dentist Bellevue would use a bright blue light called curing light that tends to harden the soft material. The composite fillings have lesser durability and long lastingness than amalgam. But, the composite fillings are taking the form of the most commonly used material for the dental fillings. These fillings are created of a plastic or resin material that makes them relatively more costly in comparison to amalgam. These usually need to get replaced after about each 5 years time period.

3. Ceramic fillings :

These fillings are created of porcelain. These are durable and aesthetically pleasing as well. This material is more costly in comparison to other filling materials. The ceramics come as tooth-colored and these are more resistant towards staining or abrasion in comparison to composite resin.

The drawback of using this material is that it is relatively more brittle than composite. It requires being sufficiently large to avoid getting break. The tooth needs to be decreased in size for accommodating the additional bulk. Such restorations usually get referred as onlays or inlays.

4. Glass Ionomers :

These are created of acrylic and glass. These typically survive lesser than 5 years of time period. These are a fine choice for children as their teeth are in the still changing phase. Glass ionomers are known to release the fluoride that helps to protect tooth from getting further decay.

The drawback of such fillings is that they are considerably weaker in strength in comparison to composite resin. Due to this they can likely get fracture and wear. The conventional glass ionomer would not match the tooth color of a person as accurately as what you get from composite resin.

5. Gold fillings :

These are not commonly used as it is an expensive option. But gold is a sturdy as well as non-corrosive material. Getting the placement of gold filling is not very convenient as it usually takes more than one visit to the dentist Bellevue for properly fitting them. This material can last for more than 15 years. You may it tough to locate a dentist offering this kind of filling as this material is getting replaced with other materials which match the natural teeth color.
