Fillings are primarily used to restore the natural shape, function, and integrity of teeth that have been affected by minor erosion or decay (cavities). If cavities are left untreated, they can progress to more serious issues such as infections, abscess formation, and in severe cases, even tooth loss. Early treatment with fillings helps prevent further damage and preserves your natural teeth.

Types of Fillings and Their Applications

There are two main types of fillings: indirect and direct, depending on how they are fabricated and placed.

Indirect Fillings (Inlays and Onlays):

Indirect fillings require two or more appointments. During the first visit, the decayed or damaged portion of the tooth is prepared and impressions or digital scans are taken. These impressions are sent to a dental laboratory, where the filling is custom-made to perfectly fit your tooth. At a subsequent visit, the tailored filling is fitted and bonded securely to the tooth.

• Porcelain Inlays and Onlays:
  Porcelain is a popular choice for indirect fillings because it closely mimics the natural translucency and colour of tooth enamel, resulting in a highly aesthetic and natural-looking restoration. Porcelain is also highly durable and stain-resistant, making it a long-lasting option. Inlays are used to restore small areas within the cusps of the tooth, while onlays cover one or more cusps and can extend to cover the entire biting surface if necessary.

• Gold Inlays and Onlays:
  Gold has been used for dental restorations for many years due to its excellent durability, strength, and biocompatibility. Gold fillings are custom-made and precisely fitted to the tooth. Though less common today due to their metallic appearance and cost, gold onlays and inlays are still valued for their longevity, sometimes lasting several decades. They are an excellent choice for patients prioritising function and durability over aesthetics.

Direct Fillings:

Direct fillings are applied and shaped directly in your mouth during a single visit, making them a quick and convenient option for restoring small to moderate cavities.

• Composite Fillings:
  Composite resin is the most popular material for direct fillings because it is tooth-coloured and can be closely matched to your natural tooth shade. Composites are made from a mixture of powdered glass or ceramic particles combined with a resin base, providing both strength and aesthetics. Advances in composite materials have enabled dentists to use minimally invasive techniques, preserving more of your healthy tooth structure. Composite fillings bond chemically to the tooth, helping to reinforce the remaining tooth and prevent further damage.

• Silver (Amalgam) Fillings:
  Amalgam fillings are made from a blend of metals including silver, tin, copper, and mercury. These fillings are highly durable, resistant to wear, and are often used for back teeth that endure heavy chewing forces. Although amalgam fillings are long-lasting and cost-effective, their metallic colour makes them less popular for visible teeth. Amalgam is still a reliable option in many cases, especially for larger cavities or patients with limited budgets.

Additional Information:

• Longevity and Maintenance:
  The lifespan of fillings varies depending on the material used, location in the mouth, your oral hygiene habits, and lifestyle factors such as diet and grinding habits. Composite fillings typically last around 5-7 years, porcelain inlays and onlays can last 10-15 years or longer, and gold restorations may last several decades. Regular dental check-ups allow your dentist to monitor your fillings for any signs of wear or failure.

• Choosing the Right Filling:
  The choice of filling material depends on factors such as the size and location of the cavity, aesthetic preferences, budget, and any allergies or sensitivities you may have. Your dentist will discuss these options with you and recommend the most appropriate treatment for your individual needs.

• Procedure Comfort:
  Modern dental techniques and local anaesthetics make filling treatments comfortable and virtually painless. For anxious patients, sedation options may be available.

• Preventing Future Decay:
  While fillings restore damaged teeth, prevention remains key. Maintaining good oral hygiene, reducing sugar intake, and attending regular dental visits will help prevent further decay and keep your smile healthy.
