Different Types of Fillings
The number one advantage of gold fillings is that they are more durable. They mostly last 10-15 years or even longer at times.Very rarely do gold fillings corrode away. At the same time, gold fillings also cost a lot more than all the others ones. In regards to strength, they are one of the strongest amongst the other available. Gold fillings can withstand any chewing force, from dried fruits to even cracking a nut open. It also comes down to aesthetic. Some people prefer gold fillings solely because it visually appeals to them. Conversely, many even dislike it and prefer simple fillings which match the rest of their teeth.
Another disadvantage of gold fillings is that they require additional visits to the dentist as compared to the simple other fillings.
Silver or Amalgam Fillings
These fillings last longer too, around 10-15 years or sometimes even more. And they do this while costing so much less than the gold fillings. In fact, they even cost less than composite fillings.
Silver fillings (amalgams) are equally strong as the gold fillings; able to withstand any sort of chewing force.
However, there are many disadvantages to amalgam fillings. The first is that they tend to create a gray hue in all the surrounding tooth structure. Thus, making itself and all the teeth around it seems less aesthetic due to the discoloration.
Also, they lead to cracks and fractures since amalgam fillings experience more expansion and contraction. This causes the surrounding teeth to crack or fracture under the force of the fillings.
The main reason so many people prefer these fillings is that they are aesthetic, as they blend in with all the other teeth. However, these too cost a hefty amount; way more than the amalgam ones.
Composite fillings provide better support, as they chemically bond to the tooth structure. Also, less tooth structure needs to be removed when fitting these in, as compared to the other fillings. However, these fillings have greater disadvantages. They are one of the least durable types of fillings. They cannot withstand any chewing force and may break when chewing harder items. Also, composite fillings chip off easily. Like gold fillings, these too require more than one visit to the dentist. They also take greater time to place than the amalgam fillings.
