Silver and gold are the tradition materials used for filling cavities. However, the advancement in dentistry has introduced more options such as tooth colored fillings. Get to know about each one of them in detail:
- Silver: It is the least expensive filling material, is quite durable and lasts long, but has several drawbacks. It causes discoloration of teeth and makes them vulnerable to breakage. Silver tends to contact and expand with cold and hoot foods. This can cause the filing to come out.
- Gold: It costs more than silver but is noticeable. It has potential risk of galvanic shock when gold and silver filings are placed together. Galvanic shock is basically a situation characterized by acute pain in mouth when gold filling next to silver comes in contact with saliva.
Tooth colored: these filings are not noticeable at all, and that is why it has an aesthetical appeal to it, compared to metal fillings. There are many types that fall under this category; your dentist will decide which one is the best one for you. However, ceramic and composite are the most popular choices in this category of fillings.
- Composite resin: Its appearances resembles to putty like substance. The dentists apply it on tooth let it harden via curing process which leaves a durable finish. It restores the lost strength of damaged tooth.
- Ceramic: it is extremely durable. Just like composite fillings, ceramic requires very minimal removal of tooth as opposed to metal fillings. This helps in preserving the natural strength and structure of tooth and minimizes the risks of breakage. With right care, ceramics can last more than 15 years.
