According to the World Health Organization, 60 to 90% of school children and nearly 100% of adults worldwide have dental cavities. Depending on how much decayed tooth material needs to be removed, it's likely your dentist will apply a filling to restore the shape and function of your tooth. Dr. Kami Hoss discusses the different tooth fillings there are, and the pros and cons of each:
1. Amalgam – Dr. Kami Hoss shares this interesting trivia about amalgam fillings: did you know that this material has been used as a tooth filling for more than 150 years? That's right; 150 years. Amalgam is composed of different metals (at least 50% mercury, tin, copper, silver, or zinc). There's nothing to worry about its mercury content a Dr. Kami Hoss says that the amount of mercury in amalgam fillings is considered safe for patients over the age of six. Sturdy and long-lasting, amalgam is ideal for the patient working with a small budget. However, it must be noted that amalgam fillings are one of the most noticeable, as its silver content can darken over time.
2. Composite – Meanwhile, composite fillings are made up of powdered glass and acrylic resin. Compared to the durability of amalgam fillings, composite fillings have a shorter shelf-life. But what they may lack in durability, they make up for with their flexibility to match the color of teeth. This means if you want to achieve a natural-looking appearance, you can opt for composite fillings. Dr. Kami Hoss finds composite fillings are best for filling up small cavities or teeth that aren't mainly for chewing such as the first six upper and lower teeth.
3. Gold – According to the American Dental Association, gold fillings can last up to two decades. This is because gold doesn't corrode and it's strong enough to withstand impact from chewing. Dr. Kami Hoss adds that this advantage of gold fillings is not without a price. In fact, the price of gold fillings can be steep, up to 10x the price of their amalgam counterpart. Depending on your aesthetic preference, the look of gold may or may not appeal to you as well, so this should be factored in when you choose a material filling for your cavities.
4. Porcelain – Dr. Kami Hoss points out that gold and porcelain are indirect fillings. This means you will be spending more time on the dentist's chair getting them compared to other materials. However, their similarities end there. Porcelain is not as durable as gold fillings. Ceramics or porcelain fillings can also be made to appear natural and are resistant to stains.
5. Glass Ionomer – Adults have plenty of options for fillings, but what about children? Dr. Kami Hoss recommends glass ionomer for filling up kids' cavities. One distinct advantage of this material is that it releases fluoride to protect the teeth. However, it's also fragile and prone to wear and tear. Generally, glass ionomer lasts up to five years.
