Comparing the 5 Types of Dental Fillings

By Family Dentistry & Aesthetics Inc. | January 4, 2023

When it comes to dental fillings, how do you know which one is right for your needs? Dental fillings are used to treat various dental issues, and many options are available in terms of material. Each type of filling comes with its own set of advantages and drawbacks. In this blog post, we will compare the five most common types of dental fillings – amalgam, composite resin, ceramic, gold alloys, and silver diamine fluoride – so that you can choose the best solution for your situation. In addition, we’ll discuss what they’re made from and how they should be used to maximize their effectiveness. So read on to learn more about these five types of fillings!

Types of Dental Fillings

Silver Amalgam Fillings

This filling is exceptionally popular. Silver amalgam fillings are a combination of silver and other minerals like tin, zinc, copper, and mercury. It’s a popular alternative because it’s affordable, long-lasting, and durable. Typically, a silver amalgam filling has a lifespan of 12 years. In addition, dentists appreciate its adaptability, which makes it simple to use.

The most significant downside makes it a poor option for a front tooth. Teeth can crack because the material contracts and expands in response to temperature variations. If the tooth moves around in its socket, there could be a space between the filling and the tooth. This would allow food and germs to enter and lead to the development of new cavities. Mercury in silver amalgam has caused debate, but the filling substance has been deemed safe for usage.

Composite or Tooth-Colored Fillings

Composite fillings are manufactured from composite resin material and plastic and are cured or cemented using a special light (or UV light) once they have been inserted into the tooth cavity. Unlike silver amalgam fillings, which stand out against the patient’s natural teeth, composite fillings match the color of the patient’s teeth.

Composite dental fillings tend to wear out sooner than other options. Every 5–10 years is about how long they last before needing to be changed. 3 In addition, they cost more than silver.

Ceramic Fillings

Ceramic fillings are tooth-colored restorations used to replace old, metal amalgam fillings. Amalgam fillings contain mercury, and many people choose to replace them with ceramic fillings because they do not contain mercury.

Ceramic fillings are made of a composite material that is strong and durable. They are also biocompatible, which means that they are safe for your teeth and gums. In addition, ceramic fillings look natural and will not change the color of your teeth over time.

If you are considering getting ceramic dental fillings, visit a dentist specializing in this type of dental restoration.

Gold Fillings

Gold dental fillings are popular for people who want a natural-looking, long-lasting restoration. Gold is a non-toxic metal that is gentle on the teeth and does not corrode. It is also resistant to plaque buildup, which can help keep your smile healthy and sparkling. However, gold fillings are both costly and unusual. In fact, it may be challenging to locate a dental practitioner who is willing to provide gold restorations. Further, a gold filling requires more than one dentist visit to ensure a correct fit. A gold filling can survive for almost 20 years since it is strong, does not corrode, and is not easily damaged.

Silver Diamine Fluoride

Silver diamond fluoride (SDF) is a newly developed dental filling material that contains silver, diamond, and fluoride. It was created as an alternative to traditional dental fillings, which can contain mercury. SDF is non-toxic, biocompatible, and easy to use. It is also very durable and resistant to wear and tear. SDF is effective in preventing tooth decay and cavities.

If you are looking for a safe and effective dental filling material, SDF may be the right choice for you. Talk to your dentist about whether SDF is right for you.

Indirect Fillings

Indirect restorations, like tooth-colored fillings, are created at a dental laboratory and must be placed over two appointments. Indirect fillings are an option when there is not enough healthy tooth structure to place a traditional filling, and the damage to the tooth does not warrant a crown.

During the initial appointment, decay or old fillings are removed. A dental impression is taken to capture the contour of the tooth being fixed and the adjacent teeth. The impression is submitted to a dental laboratory where the indirect filling will be fabricated. The tooth is protected with a temporary filling (detailed below) while the permanent restoration is being manufactured. During the second visit, the dentist will remove the temporary filling and examine the fit of the indirect restoration. If the fit is satisfactory, it will be fixed in place permanently.

Direct Fillings

Direct dental fillings involve the use of a tooth-colored material that is placed into a tooth cavity in order to restore its shape and function. This material can be made from a variety of different materials, including plastic, glass ionomer cement, composite resin, and dental amalgam.

The most common type of direct dental filling is composite resin, which is composed of plastic and glass particles that are held together by a resin matrix. Composite resin can be used to repair both small and large cavities, and it can also be used to correct discoloration or mismatches in the color of teeth. Composite resin is also the most esthetic filling material available, and it can be matched to the color of any tooth.

Why do I feel pain around my dental filling?

Tooth sensitivity to hot and cold after a filling is placed frequent. Pressure, air, sugary foods, and temperature could all make your teeth uncomfortable. The sensitivity after placement typically subsides on its own within a few weeks. In the meanwhile, staying away from whatever is making you sensitive is the best option. You probably won’t require any pain medication.

It is also possible that you are feeling pain around your dental filling because the adhesive that was used to attach the filling to your tooth may be irritating. Another possibility is that you have allergies to metal surfaces. If the pain persists, it is important to see your dentist to determine the cause of the pain and to discuss possible dental treatment options.

When would a dental filling need to be replaced?

A dental filling would need to be replaced if it became damaged or if it lost its structural integrity. A dental filling may become damaged if it is subjected to a lot of force (as can happen when you chew on something hard) or if it is exposed to chemicals (such as those found in tobacco smoke). A dental filling may lose its structural integrity if too much of the white material that makes up the filling is removed.

Are Amalgam Restorations Safe?

Autism, Alzheimer’s, and multiple sclerosis may be linked to mercury fillings. FDA and public health agencies have cleared silver (mercury-based) amalgam fillings. The FDA has updated guidelines on who should get amalgam fillings. According to them, the following people should avoid mercury-containing dental fillings wherever possible:

  • People with an allergy to mercury
  • People who already have a neurological disease, such as Alzheimer’s, Parkinson’s, or multiple sclerosis.
  • People with amalgam allergy
  • Women who want to get pregnant. Women who are pregnant and their growing babies.
  • Children, especially those who are younger than six.
  • Nursing women and their newborns
  • People whose kidneys don’t work well

What is the safest type of filling?

There is no definitive answer to this question, as many variables can affect the safety of a dental filling. However, tooth-colored composite fillings (made of plastic and glass) are generally considered safer than typical silver amalgam fillings (made of mercury and other metals). Composite fillings are less likely to cause an allergic reaction and release fewer toxins into the body.

Amalgam fillings are more durable than composite fillings, but they may eventually cause damage to the surrounding tooth structure. They also release high levels of mercury, which can harm the body. For these reasons, most dentists now recommend composite fillings over amalgam fillings.
