I need a filling – what types are there?
There are a number of different fillings, including:
- Amalgam (silver coloured).
- Composite fillings (tooth coloured).
- Glass ionomer (tooth coloured).
- Gold inlays and onlays (gold coloured).
- Porcelain inlays (tooth coloured).
What are amalgam fillings?
Amalgam fillings are silver coloured. They are made by combining mercury and a silver alloy (50% mercury, 35% silver, and 15% tin, copper and other metals). Amalgam is long lasting and hard wearing and has been used in fillings for at least 150 years. It is economical to use and it is not unusual for an amalgam filling to last 15 to 20 years.
This kind of filling is usually used on the back ‘chewing’ teeth. Before the filling can be placed, the dentist must prepare the area by removing all the and shaping the cavity to hold the filling in place. If the tooth is badly broken, your dentist may need to place a small stainless steel pin to help secure the filling.
Are there any risks from amalgam fillings?
The mercury in dental amalgam is not poisonous once it is combined with the other materials in the filling. Its chemical nature changes so that it is harmless.
Research into the safety of dental amalgam has been carried out for over 100 years. So far, no reputable ‘controlled’ studies have found a connection between amalgam fillings and any medical problem.
What are composite fillings?
Composite fillings are strong, but may not be as hard wearing as amalgam fillings. Composite fillings are tooth coloured and are made from powdered glass quartz, silica or other ceramic particles added to a resin base. After the tooth is prepared, the filling is bonded onto the area and a light shone onto it to set it. The dentist will choose a shade to match your own teeth, although over time staining can happen.
What are glass ionomer fillings?
Glass ionomer fillings form a chemical link with the tooth. They may also release, which helps to prevent further tooth decay. This type of filling is fairly weak. Because of this, they are usually only used on baby teeth and ‘non-biting’ surfaces such as around the ‘necks’ of the teeth. Little preparation is needed as the filling bonds directly to the tooth.
What are gold inlays and onlays?
These can be used in most areas of the mouth. An inlay is small and placed within the biting surface of the tooth. An onlay can cover a larger area of the tooth. Gold is the most long-lasting and hard-wearing filling material and will last for many years. An advantage of gold is that it does not tarnish and has great strength.
One of the differences between gold and other filling materials is that the gold filling is made in a laboratory. Your dental team will usually take an impression of the prepared cavity and send it to the laboratory for the technician to make the inlay or onlay. In the meantime, a temporary filling will be placed in the cavity. After the gold inlay or onlay has been made, your dentist will fix it in place with dental cement. This type of filling is more expensive.
What are porcelain inlays?
Your dental team can now use digital technology (called CADCAM) to design and prepare perfectly fitted porcelain inlays in just one or two visits. Porcelain inlays can also be made in a laboratory but this will need at least two visits to your dentist. Porcelain can be hard wearing and long lasting. It can also be coloured to match your natural tooth. Again, this type of filling can be quite expensive.
Where can I get more information?
Your dental team will advise you on what kind of filling material is suited to your situation. Talk to them if you would like a particular type of filling material such as tooth-coloured fillings.
Always ask for a treatment plan and a written estimate before starting any treatment.
Dental Fillings: Restoring Your Teeth and Oral Health
What are Dental Fillings?
Dental fillings are restorative materials used to repair teeth that have been damaged by decay, trauma or wear. They can be made from a variety of materials such as composite resin, porcelain, gold or silver amalgam.
The Dental Filling Procedure
The dental filling procedure typically involves the following steps:
- Step 1: Diagnosis and Treatment Planning: Your dentist will examine your teeth and determine if you need a filling. They may also recommend x-rays to assess the extent of the damage.
- Step 2: Anesthesia: Local anesthesia is used to numb the area around the affected tooth to make the procedure more comfortable for you.
- Step 3: Removal of Decay: The decayed part of the tooth is removed using a drill or laser to create space for the filling material.
- Step 4: Placement of Filling Material: The filling material is placed in the prepared cavity in layers and hardened with a special light or chemical process. Once the filling is set, it is shaped and polished to match the natural contours of your teeth.
Caring for Your Dental Fillings
Proper care is essential to maintain the longevity and optimal performance of your dental fillings. It includes regular cleaning, avoiding hard or sticky foods, and scheduling regular check-ups with your dentist.
Types of Dental Fillings
- Composite Resin Fillings: Composite resin fillings are made of a tooth-colored material that blends in with your natural teeth.
- Porcelain Fillings: Porcelain fillings are made of a strong, durable material that closely resembles natural tooth enamel.
- Gold Fillings: Gold fillings are made of a mix of gold, copper, and other metals and are known for their strength and durability.
- Silver Amalgam Fillings: Silver amalgam fillings are made from a mixture of silver, tin, copper, and mercury.
