Dental fillings are a common and effective solution for restoring teeth that have been damaged by decay or minor fractures. They help to prevent further deterioration, protect the tooth structure, and maintain long-term oral health. If you need a filling or want to learn more about the process, this guide covers the different types of fillings, the procedure, and how to make them last longer.
Types of Dental Fillings
There are several types of dental fillings, each with its own benefits. The best option for you will depend on factors such as the location of the cavity, durability, and aesthetic preferences.
Composite Fillings (White Fillings)
White fillings are made from a blend of plastic and fine glass particles, designed to match the natural colour of the tooth. They bond directly to the enamel, making them a popular choice for visible areas.
- Aesthetic and blends well with natural teeth
- Strong bonding to the tooth structure
- Suitable for small to medium cavities
- Can wear down faster than metal fillings and may stain over time
Amalgam Fillings (Silver Fillings)
Amalgam fillings are made from a combination of metals, including silver, mercury, tin, and copper. They are known for their strength and longevity, making them ideal for molars that endure heavy chewing.
- Durable and long-lasting, often over ten years
- More affordable than other options
- Silver appearance makes them noticeable
- A safe dental option for most patients
Gold Fillings
Gold fillings, also known as gold inlays or onlays, are custom-made restorations that are cemented into the tooth. They are one of the most durable options available.
- Extremely resistant to wear and damage
- Can last 15 years or longer
- More expensive than other fillings
- Requires multiple dental visits for placement
Ceramic Fillings (Porcelain Fillings)
Ceramic fillings are made from porcelain and offer a natural-looking, stain-resistant option. They are strong and durable, making them suitable for a wide range of dental restorations.
- Blends well with natural teeth
- Resistant to staining
- More costly than composite or amalgam fillings
- Can be brittle if not placed correctly
Glass Ionomer Fillings
Glass ionomer fillings contain fluoride, which helps strengthen the surrounding tooth structure and prevent further decay. These fillings are often used in children’s teeth or for small cavities in non-load-bearing areas.
- Releases fluoride to protect enamel
- Suitable for baby teeth or low-pressure areas
- Less durable than other fillings
- Can wear down faster over time
The Dental Filling Procedure
Getting a dental filling is a straightforward and painless process. The procedure typically takes less than an hour and involves the following steps:
- Numbing the Area – A local anaesthetic is applied to ensure comfort.
- Removing the Decay – The dentist carefully removes the decayed portion of the tooth.
- Cleaning and Preparing the Tooth – The area is thoroughly cleaned to eliminate bacteria.
- Placing the Filling – The chosen material is applied in layers and shaped to fit the tooth.
- Polishing and Adjustments – The filling is smoothed out, and your bite is checked for comfort.
How to Make Your Fillings Last Longer
To extend the lifespan of your dental fillings, it is important to follow good oral hygiene practices and avoid habits that may damage them.
- Maintain good oral hygiene by brushing twice daily with fluoride toothpaste and flossing to prevent decay around the filling.
- Avoid hard or sticky foods, which can cause fillings to chip or dislodge.
- Reduce sugary and acidic food and drinks, as they can weaken tooth enamel over time.
- Attend regular dental check-ups, allowing your dentist to monitor your fillings and spot any early signs of wear.
- Wear a mouthguard if you grind your teeth at night, as excessive pressure can damage fillings.
Dental fillings play an essential role in restoring teeth affected by decay and preventing further damage. Whether you choose composite, amalgam, gold, ceramic, or glass ionomer fillings, each type offers distinct benefits suited to different needs. Maintaining proper oral hygiene and attending regular dental check-ups will help to ensure that your fillings remain in good condition for years to come.
If you suspect you need a filling or want advice on the best option for your dental health, consulting a dentist is the best next step in maintaining a strong and healthy smile.
