Composite Fillings in Forest Hill, London

Are you looking for an invisible, natural-looking restoration to fill your teeth?
This is where composite fillings come in

Composite or “white” fillings are a modern and popular solution that not only restores the function of your teeth but also perfectly maintains the natural aesthetics of your smile. Unlike old-fashioned metal fillings, these tooth-coloured materials allow you to laugh with confidence, without anyone noticing your dental work.

In this guide, you will find out the answers to all your common questions.
from the benefits and safety of the procedure to the longevity, cost, and what to expect during the process
to help you make the best decision for your dental health and appearance.

What Are Composite Fillings (White Fillings)?

Composite fillings, commonly known as “white” or “tooth-coloured” fillings, are a modern and conservative method for restoring decayed or damaged teeth. Unlike old-fashioned silver amalgam fillings, these materials are made from a composite resin that allows your dentist to select a precise shade matching your natural tooth colour. The result is a nearly invisible restoration, giving you the confidence that no one will notice your filling when you speak or laugh.

These modern materials are not only aesthetically superior but also help preserve healthy tooth structure. This is because their placement requires your dentist to remove less of the tooth compared to metal fillings. They bond directly to the tooth, which helps to strengthen its overall structure. Composite fillings are widely used to repair decay in both front and back teeth, as well as for minor cosmetic improvements, and are a popular choice for patients seeking discreet dental care in London.

Why Choose Tooth-Coloured Fillings Over Metal Ones?

Nowadays, most patients and dentists prefer tooth-coloured (composite) fillings over older metal options. The primary reason for this choice is the natural and invisible appearance of these materials. Composite fillings blend in seamlessly with the colour of your surrounding teeth, making them undetectable when you speak or laugh and allowing you to smile with complete confidence. This is a significant aesthetic advantage that silver fillings simply cannot provide.

Biologically and functionally, these materials also offer key benefits. They are more conservative, as placing them requires far less removal of healthy tooth structure. Unlike metal amalgams, which rely on mechanical retention to stay in place, composites form a strong chemical bond with the tooth enamel, thereby helping to strengthen the tooth’s overall integrity. Furthermore, because metal expands and contracts with temperature changes, silver fillings can crack or lead to tooth fracture over time – a risk that is significantly minimised with modern tooth coloured fillings. This superior approach is something Dr Arman Barfeie, as the best dentist in London, understands and trusts for the well-being of their patients.

Composite vs Amalgam Fillings: What’s the Difference?

The choice between these two types of fillings often comes down to a decision between a natural appearance and proven durability. Composite fillings, made from a tooth-coloured resin, allow your dentist to create a restoration that is visually indistinguishable from your natural tooth. This makes them ideal for front teeth or any restoration that is visible in your smile line. In contrast, amalgam (silver-coloured) fillings are made from a mixture of metals, including mercury, silver, tin, and copper, creating a dark and noticeable spot on the tooth.

Functionally, amalgam has traditionally been selected for larger cavities in back teeth—which endure significant pressure from chewing—due to its exceptional strength and wear resistance. However, modern composites have become significantly stronger than in the past. Another key difference is in their placement: amalgam requires a specifically shaped cavity to lock into the tooth, which can mean removing more healthy tooth structure. Composite, on the other hand, bonds adhesively to the tooth, helping to preserve its natural integrity. For a personal consultation to determine which option is best for your individual needs, we warmly recommend booking an appointment with Dr Arman Barfeie at his reputable London practice.

Are White Fillings Safe and Durable for All Teeth?

Yes, white composite fillings are now a completely safe and highly durable choice for restoring nearly all teeth, including the back teeth, which endure significant chewing pressure. Remarkable advances in dental material technology have significantly increased the composite resins’ strength and wear resistance. These materials are approved by reputable regulatory bodies, such as the UK’s Medicines and Healthcare products Regulatory Agency (MHRA), and have been used safely across the world for decades. Unlike older amalgam fillings, composites contain no mercury and integrate with your tooth’s structure through a strong chemical bond.

Although silver (amalgam) fillings were historically known for greater strength, modern composites are robust enough to withstand the chewing forces on molar teeth. The lifespan of a white filling depends on factors such as the filling’s size, the dentist’s skill, and most importantly, your own care. With good oral hygiene and regular check-ups at Dr Armans’ practice in London, a composite filling in your back teeth can last from 5 to 10 years, or even longer. It is a conservative procedure that allows the dentist to remove only the decayed portion, preserving the maximum amount of your healthy tooth structure.

Replacing Old Silver Fillings with Natural-Looking Composites

If you have grown tired of the appearance of your old, dark fillings, replacing them with tooth-coloured composite fillings is an excellent solution for restoring the beauty and natural look of your smile. This procedure in cosmetic dentistry not only transforms the appearance of your teeth but also offers health benefits. Over time, old silver fillings can crack or develop leaks at the margins, which can lead to secondary decay beneath them. By removing these fillings and replacing them with composite, you safeguard the long-term health of your tooth and receive a beautiful, seamless restoration that blends in perfectly.

Fortunately, replacing a silver filling with a composite one is a quick and non-invasive process that is typically completed in a single visit at our practice in London. Dr Arman Barfeie will first remove the old filling and any decay surrounding it. The area is then thoroughly cleaned and disinfected. After selecting a shade of composite that precisely matches your natural tooth colour, the composite material is applied in layers and hardened with a special light. Finally, the new filling is carefully shaped and polished to mimic the shine and texture of natural tooth enamel. You will leave the practice that same day with a beautifully uniform smile.

Before and After Composite Fillings: Restoring Healthy, Natural Teeth

Imagine teeth that were once covered with dark, metallic fillings or damaged by decay now looking completely uniform, healthy, and natural. This transformation is exactly what tooth-coloured fillings provide. This treatment not only addresses the issue of decay or worn-out fillings but also restores both your appearance and your confidence. The final result is a tooth that is fully functional and so aesthetically natural that even you might forget which tooth has been treated.

The difference before and after treatment is truly remarkable. Before treatment: You might be living with visible metal fillings, dark lines around old restorations, or even secondary decay causing sensitivity or discomfort. After treatment, these issues are eliminated. The new composite fillings blend seamlessly with your tooth structure, with no visible lines. This not only transforms the appearance of your smile but also protects your tooth from future decay by creating a strong seal against bacteria, ensuring its long-term health.

👉 Explore real patient results that show the power of white fillings.

Will Getting a Composite Filling Hurt?

No, having a composite filling procedure is typically a painless process with very little discomfort. Your dentist will take every necessary step to ensure your comfort throughout the appointment. If your decay is superficial and only involves the tooth enamel (which is a hard tissue with no sensitive nerves), you may not even require an anaesthetic injection. For deeper cavities that approach the sensitive inner layer of the tooth (the dentin), the dentist will use a local anaesthetic to completely numb the area, meaning you will likely only feel some slight pressure during the process, not pain.

One of the best advantages of tooth-coloured fillings is the immediate recovery with no downtime. The effects of the local anaesthetic typically wear off within a few hours, and you can return to your normal activities straight after leaving the surgery. You might experience minor sensitivity to hot or cold for a few hours after the numbness subsides, but this sensation usually passes quickly and on its own. By maintaining good oral hygiene, you can expect the treated tooth to feel completely natural with no persistent pain. For those in the capital, this makes the treatment a convenient option for a busy lifestyle in London.

What to Expect During and After the Composite Filling Procedure

By booking an appointment at Dr Arman’s Clinic, you can relax and enjoy the journey to perfecting your smile. We will be with you every step of the way, explaining the process to give you complete peace of mind.

During the procedure:

  • Preparation: The dentist will first examine the tooth and, if needed, use a local anaesthetic to ensure you are completely comfortable.
  • Cleaning: The decayed area or old filling is carefully removed, and the tooth is thoroughly cleaned and dried.
  • Bonding: A special gel is applied gently to the tooth to prepare it for the composite to adhere.
  • Application: The composite material, matched to your tooth colour, is applied in layers and hardened (cured) with a special blue light.
  • Final Polishing: Once hardened, the filling is carefully shaped and polished until it is perfectly smooth, shiny, and indistinguishable from your natural tooth.

After the procedure:

  • Immediate Recovery: Once the anaesthetic wears off (usually within a few hours), you can return to your normal activities.
  • Temporary Sensitivity: You may experience mild sensitivity to cold or pressure for a few days; this is completely normal and will subside quickly.
  • Aftercare: You can eat immediately after the procedure, though it is better to avoid strongly coloured foods and drinks for a few hours. You can resume your normal oral hygiene routine (brushing and flossing). For a durable and aesthetically pleasing result, the entire process of placing composite fillings at our London practice is designed for your comfort and satisfaction.

👉 Step through the process with clarity—no surprises, just confidence.

How Long Do Composite Fillings Last?

With proper care, a high-quality composite filling can last an average of 5 to 10 years. Some may even remain in good condition for a longer period, up to 15 years or more. Its exact lifespan depends on factors such as the size and location of the filling (front teeth endure less pressure than molars), your dietary habits, and most importantly, the quality of your oral hygiene. Unlike old metal fillings, composites will not corrode over time, but they can wear down or become stained without proper care.

The long-term durability of a filling largely depends on your habits. By following a few simple tips, you can protect your investment:

  • Excellent Hygiene: Brush twice daily with a non-abrasive toothpaste and floss every day to prevent decay around the edges of the filling.
  • Avoid Excessive Force: Refrain from chewing ice, hard sweets, or biting on hard objects that could damage the filling or the tooth itself.
  • Regular Check-ups: Attending regular dental appointments for check-ups and professional cleaning allows your dentist to monitor the health of your composite fillings and repair or polish them if necessary. Regular maintenance is key to enjoying their benefits for many years.

Can You Fill Cavities in Front Teeth with White Fillings?

Yes, absolutely! Filling cavities in your front teeth using tooth-coloured material (composite fillings) is not only possible, it is considered the best and most natural method available. Since your front teeth are central to your smile line and are always on show, Dr Arman Barfeie, as a top expert, employs a true artist’s skill to ensure any composite bonding perfectly matches the exact colour, translucency, and texture of your natural enamel. Under his care, the final result is a seamless, undetectable restoration that blends invisibly, even upon the closest inspection.

A major advantage of a composite for front teeth is its conservative nature. The dentist only removes the decayed portion of the tooth, manipulating a minimal amount of healthy tooth structure. Unlike procedures such as crowns, which require significant reshaping of the tooth, composite allows for the preservation of most of your natural tooth. The material is meticulously shaped and polished after application to mimic the shine and optical characteristics of your natural tooth, creating a seamless blend. This makes it an ideal method for restoring the health and beauty of your smile without compromising its natural appearance.

👉 Yes—you can restore front teeth beautifully without visible marks.

How Much Do Composite Fillings Cost in London?

The cost of composite fillings can vary depending on the complexity of the work, the dentist’s expertise, and the practice’s location. For larger, more complex fillings that require more time and skill, the cost may be higher. If several teeth need restoring, some practices offer packaged pricing, which can be more cost-effective.

What Factors Influence the Price?

  • Size and Location of the Filling: Small fillings in front teeth (which require a greater level of artistic precision) may be priced differently from large fillings in molar teeth.

Dentist’s Expertise: Dentists who specialise in cosmetic dentistry or use premium materials may charge higher fees. To understand the specific investment for your treatment, it is best to seek a detailed consultation for composite fillings in London, so book your appointment.

FAQ

This is a very common question. A white composite filling is a tooth-coloured resin material that is bonded directly to your tooth to repair a cavity. The key differences are:

  • Aesthetics: It's matched to your natural tooth colour, making it virtually invisible.
  • Bonding: It chemically bonds to your tooth structure, which can help support and strengthen the remaining tooth.
  • Preparation: It often requires less removal of healthy tooth structure compared to amalgam fillings, preserving more of your natural tooth.

Modern composite materials are incredibly strong and durable, making them an excellent choice for most teeth. While historically amalgam was considered stronger for large back teeth, advancements in composite technology have significantly closed this gap. For most typical cavities, a composite filling provides a long-lasting solution that blends seamlessly with your smile. Your dentist will advise if a different restoration (like an inlay or crown) is better for very large cavities.

The process is a bit more meticulous to ensure a perfect result. After removing the decay, your dentist will meticulously layer the soft composite material into the tooth and shape it. Each layer is hardened with a special blue light. The main difference you'll notice is that the area needs to be kept completely dry during the procedure, so we use a small rubber dam (a protective sheet) to isolate the tooth. This ensures the strongest possible bond.

It's not uncommon to experience some mild sensitivity to hot or cold for a few days or weeks after a new composite filling. This usually settles down on its own as the tooth adjusts. This sensitivity is typically temporary. However, if it persists or you feel any sharp pain when biting, it's important to contact us. It can be a simple fix, like adjusting the bite on the filling.

Absolutely. Many patients choose to replace their old amalgam fillings with white composite ones for a natural look. We can assess the condition of your existing fillings and discuss the best course of action. Replacement is only recommended if the old filling is worn, leaking, or damaged, or if you simply wish to improve the appearance of a visible tooth. We never recommend removing healthy, functional fillings unnecessarily.

Care for it just like your natural teeth! Excellent oral hygiene—brushing twice a day and flossing daily—is key to preventing new decay around the edges of the filling. While highly stain-resistant, minimising exposure to staining agents like coffee, tea, or red wine will help it stay looking its best for longer. Your filling will be checked at your regular dental check-ups to ensure it remains in perfect condition.
