Dental Fillings in the UK: Types, Procedures, and Considerations

Dental fillings are a common restorative treatment used to repair teeth damaged by decay, fractures, or wear. In the United Kingdom, dental fillings play a crucial role in preserving oral health and preventing further dental complications. In this comprehensive guide, we explore the types of dental fillings, the procedures involved, and important considerations for patients in the UK.

Understanding Dental Fillings

Dental fillings are materials used to restore the structure, function, and integrity of teeth affected by cavities or damage. The primary goal of dental fillings is to remove decayed or damaged tooth structure, clean the affected area, and fill the cavity with a suitable material to prevent further decay and restore tooth function.

Types of Dental Fillings

Amalgam Fillings: Amalgam fillings, also known as silver fillings, are composed of a mixture of metals, including silver, mercury, tin, and copper. Amalgam fillings are durable, cost-effective, and long-lasting, making them a popular choice for restoring posterior teeth where chewing forces are higher.

Composite Fillings: Composite fillings are made of a tooth-colored resin material that can be precisely matched to the natural color of the patient’s teeth. Composite fillings are aesthetically pleasing and offer excellent cosmetic results, making them suitable for front teeth or visible areas of the mouth.

Glass Ionomer Fillings: Glass ionomer fillings are a blend of acrylic and glass powders that release fluoride to help prevent further decay. These fillings are commonly used for small cavities in children or as temporary fillings in adult teeth.

Porcelain Fillings (Inlays and Onlays): Porcelain fillings, also known as inlays and onlays, are custom-made restorations fabricated in a dental laboratory. These fillings are highly durable and can be color-matched to blend seamlessly with natural teeth. Porcelain fillings are often used for larger cavities or areas of extensive damage.

The Dental Filling Procedure

The dental filling procedure typically involves the following steps:

Assessment and Diagnosis: The dentist examines the patient’s teeth using visual inspection, dental probes, and X-rays to identify cavities or areas of tooth decay.

Anesthesia: Local anesthesia is administered to numb the affected tooth and surrounding tissues, ensuring patient comfort during the procedure.

Removal of Decay: The dentist uses dental instruments, such as drills or lasers, to remove decayed or damaged tooth structure and prepare the cavity for filling.

Placement of Filling Material: Once the cavity is cleaned and prepared, the dentist fills the space with the selected filling material, ensuring proper shaping and contouring to restore the tooth’s natural shape and function.

Curing and Polishing: For composite fillings, a special curing light is used to harden the material. The filling is then polished to smooth out rough edges and achieve a natural appearance.

Final Adjustment: The dentist checks the patient’s bite and makes any necessary adjustments to ensure proper alignment and occlusion of the filled tooth with adjacent teeth.

Considerations for Patients in the UK

Cost and Affordability: The cost of dental fillings in the UK can vary depending on factors such as the type of filling material used, the location of the dental practice, and the complexity of the procedure. Patients should inquire about the cost of treatment and explore payment options, including dental insurance coverage or financing plans.

Aesthetic Preferences: Patients may have aesthetic preferences regarding the appearance of dental fillings, particularly for visible areas of the mouth. Dentists can discuss the advantages and disadvantages of different filling materials and help patients make informed decisions based on their cosmetic goals and budget.

Long-Term Durability: While dental fillings are designed to be durable and long-lasting, factors such as oral hygiene practices, diet, and dental habits can influence their lifespan. Patients should follow good oral hygiene practices, attend regular dental check-ups, and avoid habits that may compromise the integrity of fillings, such as teeth grinding or chewing on hard objects.

Health and Safety Standards: Patients should choose a reputable dental practice with experienced dentists who adhere to strict health and safety standards. Dentists should use high-quality materials, sterilized instruments, and proper infection control protocols to ensure patient safety and minimize the risk of complications.


Dental fillings play a critical role in preserving oral health and restoring the function and appearance of teeth affected by decay or damage. In the UK, patients have access to a variety of filling materials and treatment options tailored to their individual needs and preferences. By understanding the types of dental fillings available, the procedure involved, and important considerations for patients, individuals can make informed decisions about their oral health and work collaboratively with their dentists to achieve optimal treatment outcomes and maintain healthy smiles for years to come.
