Dentists treat cavities regularly via the dental filling procedure. The first step is to clean out the decayed portion of the tooth, which leaves behind a space inside the tooth. This space is filled with a dental filling material. It protects the tooth for the long term. Depending on the material used, the dental filling types differ.
In this article, we will explain the five different types:
Composite fillings are made of a resin and plastic substance that is inserted into the cavity while it is still soft, then solidified under a strong blue curing light.
It is a popular choice since it makes it easy to match the colour of a person’s natural teeth, allowing the filling to be less noticeable. However, these do not endure as long as other types. They should be replaced every five to ten years on average.
Glass Ionomer Fillings
These are made of glass and acrylic are ideal for toddlers whose teeth are still developing. They release fluoride, which can help to protect teeth from decay. However, because they are substantially weaker than composite fillings and are more likely to shatter or wear out, they only last a few years. Traditional glass ionomers do not match the colour of your teeth as well as the composite resin material.
These are made of porcelain and are both long-lasting and appealing to the eye. Ceramic fillings are more expensive than composite fillings, but they are tooth-coloured and resistant to discolouration and abrasion.
The disadvantage of choosing ceramic rather than composite is that it is more fragile, requiring a bigger size to avoid shattering. This necessitates enlarging the tooth’s surface area to accommodate the added bulk. Inlays and onlays are the terms used to describe these ceramic restorations.
Silver Amalgam Fillings
This is the most well-known among the dental filling types. Silver amalgam is a mineral mixture containing 50% of silver, tin, zinc, and copper, as well as 50% mercury. It is a favourite dental filling material among dentists since it is robust, long-lasting, and inexpensive.
The average silver amalgam filling can last up to 12 years. Silver amalgam is also rather simple for a dentist to place in a cavity, and there is little risk of it becoming contaminated by blood or saliva.
However, there are several drawbacks to using silver amalgam. Because it is unattractive, it is not a good choice for highly visible teeth (for example front teeth). The material can also expand and compress with time, leading to the cracking of a tooth. Food and bacteria can become trapped between the filling and the tooth as a result of these variations, allowing new cavities to form.
Additionally, these fillings are not advised for people with high-risk conditions. A dentist will be able to guide their patients on this matter.
These are costly and uncommon. In fact, finding a dentist who will offer gold as a material option can be tough. Furthermore, the appropriate placement of a gold filling necessitates more than one dental visit. On the other hand, it is durable, does not corrode, and can survive for more than 20 years.
