What Are Dental Fillings and Why Do We Need Them?

Dental health is a crucial aspect of overall well-being, and maintaining a healthy set of teeth involves various preventive and corrective measures. One common dental procedure many people undergo is getting a dental filling. Which leads to the common question; Exactly what are dental fillings?

This article will delve into what dental fillings are, why they are needed, the types available, and the process involved in getting one. By understanding these aspects, you can make informed decisions about your dental health.

What Are Dental Fillings?

Dental fillings are restorative materials used to repair minor to moderate tooth damage. They are typically applied after removing decayed material from a cavity, restoring the tooth’s structure and function.

Fillings help to seal the affected area, preventing further decay and maintaining the tooth’s integrity. They are an essential part of dental care, offering a simple yet effective solution for tooth decay and minor fractures.

Why Do People Need Dental Fillings?

Dental fillings are primarily needed to treat cavities caused by tooth decay. When you consume sugary or starchy foods, the bacteria in your mouth produce acids that can erode the tooth enamel, leading to cavities.

If left untreated, these cavities can cause significant pain, infections, and even tooth loss. Fillings not only stop the progression of decay but also restore the tooth’s normal function and shape.

Additionally, fillings are used to repair cracked or broken teeth resulting from injury, grinding, or other forms of trauma. They help to strengthen the damaged tooth, providing a protective barrier against further damage and reducing sensitivity caused by exposed nerves.

What Kind of Dental Fillings Are There?

There are several types of dental fillings, each with its own advantages and applications:

Amalgam Fillings

Made from a mixture of metals including silver, mercury, tin, and copper, amalgam fillings are known for their durability and strength. They are often used for filling cavities in the back teeth where the chewing pressure is greatest. However, their metallic colour makes them less popular in visible areas.

Composite Fillings

Composed of resin and fine glass particles, composite fillings are popular due to their natural tooth colour, making them ideal for front teeth or visible areas. They bond directly to the tooth, providing good support and requiring less removal of the tooth structure. However, they may not be as durable as amalgam fillings for larger restorations.

Ceramic Fillings

These are made from porcelain and are both durable and aesthetically pleasing. Ceramic fillings resist staining and abrasion well, making them a good choice for visible teeth. However, they can be more expensive than other types.

Gold Fillings

Gold fillings are extremely durable and can last many years. They are custom-made in a laboratory and then cemented into place. While they are not as aesthetically pleasing as composite or ceramic fillings, they are highly biocompatible and wear-resistant.

Glass Ionomer Fillings

These fillings are made from acrylic and a specific type of glass material. They release fluoride, which can help protect the tooth from further decay. They are generally used for fillings below the gum line or for pediatric dentistry.

How Are Dental Fillings Done?

The process of getting a dental filling is straightforward and typically involves the following steps:

1. Diagnosis

Your dentist will examine your teeth and may use X-rays to determine the extent of decay or damage.

2. Preparation

The area around the affected tooth will be numbed using a local anesthetic to ensure a painless procedure.

3. Removal of Decay

The decayed portion of the tooth is removed using a dental drill or laser. The area is then cleaned to remove any bacteria or debris.

4. Filling Application

The chosen filling material is applied in layers. For composite fillings, each layer is hardened using a special light. The dentist will shape the filling to fit the tooth perfectly.

5. Finishing Touches

Once the filling is in place, the dentist will polish the tooth to ensure a smooth finish and proper bite alignment.
