How to Choose the Best Dental Fillings for Your Teeth-Good Oral Tooth Care and Dentists

Even In Ancient Times Dental Work Was Done on Teeth

Since the days of ancient Egypt, dental care has been practiced in one form or another. Throughout time, dentistry has become a specialized profession. Back in the Middle Ages, dentists worked on teeth and also cut hair. In the 15th Century, Italian dentists filled cavities with gold, only for the wealthy. Modern technology has afforded us many choices in dental care, and many choices in dental fillings.

Prior to 1819, cavities in teeth were filled with gold alloy. Amalgam fillings (silver and mercury) were invented as a cheaper substitute, over 150 years ago. Amalgam fillings is 50% mercury and 50% metal powder that consists of silver, zinc, copper and tin. In 1979, the University of Iowa, and later in 1981 by Ohio State University, found that mercury was released from these amalgam fillings. The vapor release was increased from brushing, chewing, and from acidic and hot drinks and foods. In 2009. Congress wrote a bill to ban amalgam fillings, but the bill was never passed. Norway, Scandinavia, Denmark and Finland have stopped the use of these fillings because of the threat of mercury.

Mercury is of Concern in Silver Fillings

90% of American dentists use amalgam fillings. In addition to the threat of mercury vapors, amalgam fillings are done in such a way that they can cause cracks in the tooth being filled. This may lead to the need for root canal. The positives of amalgam fillings is that they can last for decades.F;ouride use has helped the enamel on teeth become stronger and more cavity resistant. Regular dental exams are important to detect cavities that may exist underneath the enamel layer. Resin composite fillings are a good alternative to the amalgam fillings. These resin composite fillings are tooth colored and synthetically imitate the existing tooth naturally in functionality, aesthetics, and structure.

Silver Amalagm Fillings are Very Durable

Amalgam fillings are made up of about half mercury and half silver, with a very small amount of other metals including tin and copper. These filings are extremely durable and can last 20-25 years. They are inexpensive and easy to work with. Amalgam isn’t a pretty looking material. The idea that mercury is in the amalgam has many negatives.Mercury releases a vapor and can be absorbed by the body and could have detrimental affects. When old fillings are removed, the mecury is vaporized. Although there is no scientific evidence to support the mercury in fillings could be causing illnesses, some people may have more sensitivities than others. Pregnant women should not be exposed to amalgam fillings. It is best to avoid removing or inserting amalgam fillings in expectant mothers. Mercury is known to cross the placenta.

Composite Resin is Good for Children's Teeth

In children, non mercury fillings are best used to repair tooth decay. A popular alternative to amalgam fillings is composite resin or white fillings. They are also known as bonding fillings or plastic fillings. Technology has made these type of fillings easier to work with, aesthetic to look at and stronger than ever.It is the same color as teeth, and can be matched closely in shade, and can be used on front teeth without attracting attention.Only recently are they being made strong enough for back teeth. May last 5-10 years on back only teeth. More expensive to produce, harder to work with. Secondary tooth decay can develop around the edges with composite resins.Gold and porcelain are alternatives to dental amalgam and composite resins. Gold and porcelain are more expensive, but precise in the ability to work with. Offer the most durability.

Before You Get Fillings - Know Your Choices

Whether the mercury is safe in fillings is still being debated.Mercury is a liquid that binds with amalgam alloy which is a combination of metal - silver, copper, tin, and zinc. The combination of metals is soft and malleable so the dentist can use it to fill cavities. When it hardens it becomes a strong filling. The American Dental Association states that mercury in the amalgam is stable and safe.Mercury contaminated fish is unsafe. Both sides debate about the safety in tooth fillings. People vary on how much mercury is absorbed. Genetics, things like teeth grinding, chewing gum and the number of fillings play a part in the amount of mercury vapor absorbed.Because of the concern about mercury content, other fillings are starting to be designed. So far amalgam (silver colored fillings) are the longest lasting and the least expensive.Millions of people have amalgam fillings. Before you get your cavities filled, know whatever you can about the things going into your mouth.

Silver Amalagm is the Most Common Fillings for Cavities

The FDA needs to define a safe dosage of mercury from the fillings. The current mercury vapor safety metric calculated by the EPA (Environmental Protection Agency). Dental amalagm is the most common material used to fill dental cavities. Amalgam was introduced in the U.S. by 2 French businessmen in the early 19th century. Prior to amalgam, tin, lead and gold were used to fill molars. Tin did not last long. Lead was poisonous and gold leaf was expensive and time consuming to apply to teeth. In 1910, gold cast became available and became a better, gentler and lower cost alternative to filling teeth.

Coca Cola Was Invented and Cavities Became More of a Problem

In colonial America and prior most people lost their teeth to gum disease than to tooth decay. People’s diet consisted of low sugar and high fat. Only the rich could afford the expensive commodity of sugar. Tooth decay was known as a rich man’s diseases In America, sugar was cheaper, but people rarely indulged. Around the same time Coca Cola was introduced in 1886, dental cavities became more prevalent. Even today, The Coca Cola Company is the biggest purchaser of sugar in the world. Back then Coke was made with real cocaine, so people got hooked on it easily. Its popularity swept across the country quickly, and so did rotten teeth. Dental cavities are the most common ailment across the globe.

Hi Cathy, It is always good to ask your dentist the right questions. But there is every possibility that your dentist did not want to use fillings that contain mercury. When I had a cap put on my tooth a few years ago, I asked the dentist the pros and cons of different materials. He told me, and I chose a gold cap. No one can see it, it is pure and reacts well with the body, and I won't have to worry about it needing replacing like a porcelain cap would. But if it was in a noticeable spot, I would not hesitate for aesthetic purposes to choose porcelain. As far as my sources, I read and research and double check my sources very thoroughly before I write on any subject. I want my info to be accurate and trustworthy. Some of my info I got from my readings, some are from the American Dental Association, some from the FDA, and abcnews. Hope this helps. For my curiosity, why does your husband want to know my sources?

he's a cautious guy and many hubs i've read contain innaccuracies that i catch because of my medical training. your hub sounded authoritative and i was aware of the amalgum issue with mercury, but marc, being the cautious guy he is, wanted more. your candid answer will probably reassure others who stop by to read your good hub, too. thanks.

I'm sitting right now in the dentist office waiting to have my silver filling that I swallowed replaced. Not going with the silver because of the debate concerning the mercury.

Useful article.

My dentist doesn't give me any choice, he just fills me up with whatever he likes. I don't mind though, as long as he knows I'm not there for a haircut.

This looks like it will be very useful for USA readers, so up and useful.

Very good info, and I like your use of the table.

Unfortunately, I have a mouthful of dental work that was performed back in the days before I retired (when I still had dental insurance and an undiminished income). I know that some of my fillings and other hardware should be replaced, but can't afford to have it done. That's true for a lot of senior citizens these days.

Oh my goodness! Mercury in our mouths? I thought everybody on the planet was avoiding mercury like the plague these days. When I was a kid (dinosaurs roamed the Earth, then), we used to play with mercury. It was a lot of fun, rolling around our hands, breaking apart, and coming back together again. Nobody died, but now I wouldn't put it in my mouth. I vote for porcelain.

Thanks for all this great info!

Coming from a person in the dental industry. Amalgam fillings are terrible, the office i go to no longer offers them at all and any reputable dentist will offer you the best choices and avoids the bad stuff, why even mention it if you really wouldn't want your patient to make a bad choice and only have the best. As far as crowns, although material is important, its importance is no where near how good the workmanship is. Although they set a time limit, ive seen them last double the time and I've seen crows replaced after a year no matter what the material is because a bad job was done on the margins and decay, decay, decay. Or the decay wasn't completely cleaned before the filling. Find a good dentist, one that takes the time and is detailed, one that doesn't hire others but does the work himself and everything else won't matter. Great article though! Voted up.!

toknowinfo - great information. I have been going to the dentist since I was two. My Mom was ill while she carried me and I did not have any enamel on my teeth. As my permanent teeth cane in, they were capped. When I was in my twenties, I had to have my teeth recapped - these lasted until my sixties. Pascale comments are quite valid.

Thank you for writing such a good Hub
