White-colored fillings are mercury free fillings. They won’t harm your health like the mercury fillings can. The tooth-colored fillings are made of a composite mixture of glass and plastic. These fillings are not only less toxic than silver amalgam fillings; they’re much more pleasing to the eye.

July 28, 2009 — The mercury used in dental amalgam fillings is not at a level high enough to cause harm in patients, according to the FDA, which today issued its final regulation on the controversial tooth filling material.

While it’s improbable you can get mercury poisoning from fillings—as the level of mercury exposure from dental fillings isn’t a threat to your health—there are other circumstances where individuals may experience mercury poisoning.

These days, white fillings are the standard among most dental offices. There are two reasons for this: white fillings just look more natural than silver fillings, and white fillings are much safer than their silver counterparts.

Porcelain Ceramic Fillings Ceramic fillings contain porcelain, so they’re durable and attractive. Even though ceramic fillings come at a higher price point, many patients are happy to pay extra for dental fillings that are safe, resistant to staining, and aesthetically pleasing.

Many patients often wonder, can silver fillings be replaced with white fillings? The answer is yes. Dental amalgam, or “silver filling material” has been used for over one hundred and fifty years. It is one of the sturdiest, safest and inexpensive materials used to fill cavities.

Expensive: The cost of white teeth fillings is higher than amalgam fillings because of the advanced technology used. Not suitable for back teeth: If the decay is extensive, or on the back teeth, white fillings will get worn off sooner than silver fillings because of slightly less durability.

Modern white fillings are much stronger than those from several years ago. They are, however, very strong and a well-placed amalgam filling can last for several years. More modern white fillings are also now very strong and can also last several years when placed correctly and when used in the correct situation.

Composite fillings are an attractive option because they can be closely matched to the color of your teeth. However, composite fillings are more expensive than silver amalgam fillings and are not as durable. Ceramic fillings are made of porcelain and are a very aesthetically pleasing option that is also very durable.

How Long Do White Fillings Last? Since metal fillings aren’t made of metal, it’s natural to worry about their durability. Although they are made of a composite resin material, they can last for 10 years or longer with the right aftercare.

The composite filling can become stained or become more yellow with time. Fortunately, this discoloration is often just on the surface and after removing a few microns of the composite, it appears “refreshed.

Similar to crowns, you’ll get white fillings for front teeth, but only amalgam (metal) fillings for your back teeth. If you want a white (composite) filling for back teeth done privately, they’ll be between £40 and £260, depending on which teeth need filling.

Although amalgam fillings can release low levels of mercury vapour, particularly when they are put in or removed, there is no evidence that exposure to mercury from amalgam fillings has any harmful effects on health. Talk to your dentist if you have any concerns.

There is no single number of how many times you can have a filling replaced. Usually, we will stop replacing the dental filling after the hole becomes too large. Once you have more filling material than natural tooth material your tooth no longer holds enough strength.

A cavity is a cavity and there should be no difference between two dentists, right? The answer is not always. Unfortunately, a cavity can be deceptive. It can hide and be obscured by old fillings, location, or just not be obvious by eye or X-ray.

Composite fillings fill the cavity and bond directly to the patients teeth. Because of this, the tooth and filling work together. This means that composite fillings do not make your teeth weaker, but they may make your teeth stronger.

Saliva. The minerals in your saliva and the amount of saliva help with remineralization – the process that keeps your teeth from developing cavities. Having less saliva can make you more prone to cavities. The amount of saliva you have is influenced by a host of factors such as snoring, diet and medication.

They occur when bacteria from food sits in between the teeth and if not removed with flossing, the bacteria will slowly start to eat away at the tooth and cause decay, or, a cavity. Unfortunately, once a cavity is fully formed, it is nearly impossible to simply brush and make it go away.

Everyone’s teeth are shaped differently. They have natural grooves and ridges in different places. The more grooves and ridges, the more likely bacteria can find their way into these small spaces and cause cavities. The smoother your teeth, the less likely you’ll be plagued by cavities.

While most cavities are due to poor oral healthcare practices (such as tobacco use, an unhealthy diet high in sugar, and poor dental hygiene), research suggests that some people may have a genetic predisposition to cavities.
