Welcome to our comprehensive guide on dental fillings! At Murray Street Dental Practice, we understand the importance of maintaining excellent oral health and a beautiful smile. So in this blog post, we will delve into the world of dental fillings, explaining what they are, their benefits, and how they can help you maintain your dental health.

What are dental fillings?

Dental fillings are a common restorative dental treatment used to repair teeth damaged by decay or cavities. When tooth decay occurs, it creates holes or cavities in the enamel, which can lead to pain, sensitivity, and further dental problems if left untreated. So we use dental fillings in Llanelli because they are designed to fill these cavities. This is to restore the tooth’s function, shape, and strength while preventing the decay from spreading.

Types of dental fillings

Amalgam fillings

Amalgam fillings, also known as silver fillings, have been used for decades as a reliable and cost-effective option. They consist of a mixture of metals, including mercury, silver, tin, and copper. As amalgam fillings are durable and can withstand the forces of chewing, this makes them suitable for use in molars and premolars.

Composite fillings

Composite fillings, also called tooth-coloured or white fillings, are made from a blend of resin and finely ground glass or quartz particles. These fillings can be closely matched to the colour of your natural teeth, providing a more aesthetically pleasing option. So this makes composite fillings a versatile option as they can be used on both front and back teeth.

Ceramic fillings

Ceramic fillings, often referred to as porcelain fillings, are crafted to match the natural colour of your teeth. This then ensures a seamless blend with your smile. They are highly resistant to staining and are an excellent option for those with allergies to metal. So ceramic fillings are a popular choice for visible front teeth restorations.

Glass ionomer fillings

Glass ionomer fillings are a combination of acrylic and a specific type of glass. But these fillings are primarily used for small restorations, such as those on baby teeth and non-biting surfaces. Also, they release fluoride, which can help prevent further decay in the surrounding tooth structure.

The dental filling procedure

Examination and diagnosis

During your dental visit, our experienced Llanelli Dentists will conduct a thorough examination of your teeth and identify any signs of decay or cavities. Also, we may use X-rays to get a comprehensive view of the extent of the damage.


Before the filling procedure begins, we will administer local anaesthesia to numb the area around the affected tooth. This ensures a painless experience during the treatment.

Removal of decay

The decayed portion of the tooth will be carefully removed using specialised dental instruments. This then leaves behind a clean and healthy surface ready for the filling material.

Filling placement

The selected filling material will be placed in layers, and each layer will be hardened using a curing light. Then our skilled dentist will sculpt the filling to fit your tooth’s natural shape, ensuring a comfortable bite and a seamless appearance.

Bite adjustment

After the filling is placed, we will check your bite and make any necessary adjustments to ensure proper alignment and comfort.


The final step involves polishing the filling to give it a smooth and natural finish, making it blend harmoniously with the rest of your teeth.

Benefits of dental fillings

Dental fillings offer numerous benefits, including:

1. Restoration of function

Fillings restore the damaged tooth’s functionality, allowing you to chew and speak without discomfort.

2. Prevention of further decay

By filling cavities, we prevent the decay from spreading and causing more significant dental issues.

3. Improved aesthetics

Tooth coloured fillings provide a natural and appealing look, enhancing your smile.

4. Long-lasting results

Properly placed and cared for fillings can last for many years, offering a durable solution to dental problems.

5. Preservation of tooth structure

Dental fillings require minimal removal of the natural tooth structure, preserving its integrity.

Caring for your dental fillings

To ensure the longevity of your dental fillings and maintain excellent oral health, follow these essential tips:

1. Practice good oral hygiene

Brush your teeth twice daily and floss regularly to remove plaque and prevent new cavities.

2. Regular dental check ups

Schedule regular dental visits in Llanelli for professional cleanings and check-ups to detect any issues early on.

3. Avoid chewing hard objects

Refrain from biting on hard objects like ice or pens to prevent damage to your fillings.

Reduce consumption of sugary and acidic foods and beverages to protect your teeth from decay.
