Silver vs. White Fillings: What’s the Difference?

Being told that you have a cavity by your dentist is not exactly something that you enjoy hearing. The unpleasant experience of sitting on a chair while the dentist probes through your mouth – not to mention the cost it entails – is definitely not a welcome thought. Fortunately, with the advancements in dentistry, you now have many options when it comes to tooth repair. Previously, silver amalgam fillings is the only choice available; now we have the option of getting composite resin.

Both of these materials shave their own pros and cons. By knowing these things, you can have a more educated decision on the kind of dental filling you want – if the time comes that you need one. It is possible to just go through life without getting a cavity, but there is a high chance that you will need to get a dental filling at some point in your life. Statistics show that about 90 percent of Americans aged 20 to 64 years have at least one cavity, and it only increases with people aged over 65 years.

Before we get into the advantages and disadvantages of the materials used for dental fillings, it is important to first know what a dental filling is and its importance in your overall health and beauty. Dental fillings replaced decay in tooth enamel and restore the appearance, structure, and strength of the tooth. despite the dental enamel being the strongest tissue in the body, it still is susceptible to bacteria.

Plaque is a matrix of bacteria and minerals that forms on the teeth. Bacteria accumulate as plaque builds up. Bacteria feed on sugars and starches and create an acidic byproduct that softens the enamel. This leads to dental sensitivity and erosion, which allows bacteria to invade and cause cavities. When left untreated, the bacteria will eat away the enamel and tissue under it, leading to the formation of cavities. Down the line, the decay will penetrate the tooth canal, which will require root canal therapy or even tooth extraction.

Silver Fillings

Otherwise known as amalgam, silver fillings can last anywhere between 10 and 15 years. Their effectiveness and durability cannot be questioned, considering that they have been used even before the introduction of white fillings.

Advantages

Very strong and can withstand many years of chewing
Generally cheaper
Has a longer success rate

Disadvantages

Less aesthetically pleasing compared to the tooth-colored option
Requires removal or more healthy tooth to make room for the filling
Chips or cracks are more likely because of contraction and expansion with food and beverages of extreme temperatures
Concerns over the safety of mercury found in the fillings

White Fillings

White fillings are also called composite fillings or tooth-colored fillings and are designed to match the color of your natural teeth. Generally, these fillings can last from 7 to 10 years, depending on your oral care habits.

Advantages

Better camouflaged option with no silvery smile
A more healthy tooth is saved during the procedure
Enhanced strength because the material chemically bonds with the surface of the tooth.

Disadvantages

Cost more than silver fillings
Risk of chipping
Dentist appointments can take a little longer

The material you pick will depend on your special needs and preference, as well as the location of the filling and your budget. To replace a dental filling, your dentist will have to first remove the decay and bacteria, and thoroughly clean the tooth. The dentist will then apply the dental filling into the cleaned and prepared hole to reinforce the structural integrity of the tooth. Once the dental filling is in place, you can then go back to enjoying its restored function and improved oral health.
