Prevent Tooth

Modern dentistry provides solutions, such as tooth fillings, to combat tooth decay, which is widespread. Tooth decay usually manifests in the form of cavities, creating tiny holes or structural damage in the teeth. This dental condition often results from factors like poor oral hygiene, frequent consumption of sugary foods, and plaque buildup. Fortunately, seeking professional help for tooth fillings in Oakville can effectively combat this common oral issue. In this article, we will discuss how dental fillings prevent tooth decay and the different types of fillings available today.

What is a Dental Filling?

A dental filling is a restorative procedure where your dentist removes the decayed material from your teeth and fills it with a safe material. This process prevents further damage to your teeth and restores their normal function and appearance. Fillings are a common and straightforward procedure that can be completed in just one visit to your dentist.

How Does a Dental Filling Prevent Tooth Decay?

Tooth decay occurs when the bacteria in plaque produce acids that attack the enamel, leading to cavities. When left untreated, these cavities will continue to grow and cause more significant damage to your teeth. A dental filling prevents tooth decay by removing the bacteria and plaque from the affected area. Your dentist will clean out the damaged part of your tooth, leaving only healthy enamel behind. Afterward, they will fill the space with a strong material that seals off the cavity and prevents further bacterial growth.

Types of Dental Fillings

Dental fillings have come a long way since their introduction in the 19th century. Today, there are several types of fillings available, each with its unique benefits and drawbacks. Some common types of dental fillings include:

1.     Amalgam Fillings

These silver-colored fillings have been in use for over a century and are composed of a mixture of metals such as mercury, silver, tin, and copper. Amalgam fillings are durable and long-lasting, making them an affordable option for many patients. However, they may not be suitable for visible areas of the mouth due to their noticeable color.

2.     Composite Resin Fillings

These fillings are made from a combination of plastic and glass materials, providing a tooth-colored option that blends in seamlessly with your natural teeth. They are also durable and can withstand moderate pressure, making them suitable for both front and back teeth. However, composite fillings may be more expensive than amalgam fillings and may not last as long.

3.     Ceramic Fillings

These fillings are made from porcelain or ceramic materials, providing a highly aesthetic option that mimics the natural color of your teeth. They are also resistant to staining and can be an excellent option for larger cavities in visible areas of the mouth. However, ceramic fillings may be more costly than other options and require multiple visits to your dentist.

4.     Gold Fillings

Gold fillings are a durable and long-lasting option that can last up to 20 years with proper care. They are also highly resistant to wear and tear and can withstand the forces of chewing. However, they tend to be the most expensive option and may not be suitable for visible areas of the mouth.


Dental fillings are an essential tool in preventing tooth decay and restoring damaged teeth. With advancements in dentistry, the longevity of tooth fillings has improved over the years. By understanding how they work and the different types available, you can make an informed decision with your dentist on which filling material is best for your oral health needs. Remember to maintain good oral hygiene practices and visit your dentist regularly for check-ups to ensure the longevity of your dental fillings and overall oral health. So, don’t hesitate to schedule an appointment with your dentist for a dental filling if you notice any signs of tooth decay.
