The Philosophy: Restoration, Not Just Repair
In the past, dentistry was about "patching holes." If a tooth had decay, the goal was simply to plug the cavity with a durable material—often silver amalgam (a mix of mercury, silver, tin, and copper). While functional, these dark metal fillings were visually intrusive and mechanically primitive.
At the Cosmetic Dentistry Clinic, we do not "patch." We restore.
We utilise high-grade Composite Resin—a sophisticated mixture of glass and plastic particles—that bonds physically to the tooth structure. This allows us to practice Biomimetic Dentistry (mimicking life). We are not just filling a space; we are rebuilding the tooth's internal structure to behave exactly like natural enamel.
The result is a restoration that is invisible to the naked eye, structurally integral, and completely free of metal.
The Great Debate: Amalgam (Silver) vs. Composite (White)
Many patients come to us asking if they should replace their old metal fillings. To make an informed decision, one must understand the fundamental differences between the materials.
1. The Mechanics of Support
Amalgam (Silver)
Metal does not bond to teeth. For an amalgam filling to stay in, a dentist must undercut the healthy tooth structure to create a "mechanical lock." Furthermore, metal expands and contracts with heat (hot coffee, ice cream) at a different rate than the tooth. Over years, this acts like a wedge, often causing the surrounding tooth to crack.
Composite (White)
Resin bonds chemically to the tooth. This acts like a glue that holds the tooth structure together, reinforcing the remaining walls rather than pushing them apart.
2. The Aesthetics
Amalgam
Silver fillings turn black over time and can stain the surrounding tooth structure grey, creating a "shadow" that makes the tooth look dark even if it is healthy.
Composite
Available in dozens of shades and opacities. We layer it to match the exact translucency of your natural tooth. It is seamless.
3. The Conservation
Amalgam
Requires the removal of more healthy tooth tissue to create the necessary shape for retention.
Composite
Allows for Minimally Invasive Dentistry. We remove only the decayed portion. Because the material bonds, we can keep the filling as small as possible.
The Procedure: The Layering Technique
A white filling at our South Kensington clinic is not a single-step process. To achieve a "silent" result—one that disappears into the tooth—we employ a meticulous layering protocol.
Step 1: The Cleanse
We ensure the tooth is isolated and kept perfectly dry. We remove all decay or old metal filling material using conservative techniques.
Step 2: The Preparation
We condition the surface of the tooth with a specialised gel that creates microscopic pores in the enamel. This increases the surface area for the bond.
Step 3: The Chameleon Effect
We do not use a single "white" colour. Natural teeth have a darker, more opaque centre (dentine) and a lighter, translucent edge (enamel). We select a composite shade that mimics your specific dentine for the base, and a translucent enamel shade for the surface. This is the "Chameleon Effect"—the filling blends seamlessly with the surrounding structure.
Step 4: The Sculpting
Before the material is hardened, the dentist sculpts the anatomy of the tooth. We recreate the cusps and grooves that allow you to chew efficiently.
Step 5: The Cure & Polish
We use a high-intensity UV light to harden the material instantly. Finally, we polish the restoration using diamond pastes. This ensures the filling feels smooth to the tongue and resists staining from coffee or wine.
Synergistic Treatments: The "Restorative Upgrade"
Replacing old fillings is often the catalyst for a broader improvement in oral health and aesthetics. We frequently combine white fillings with the following treatments for a complete rejuvenation.
A. Safe Amalgam Replacement
If you have multiple old silver fillings, we can plan a phased replacement. We use high-volume suction and isolation dams to ensure that as we drill out the old mercury-based fillings, you do not ingest the debris or vapour. This is a health-conscious upgrade for your entire mouth.
B. Whitening Protocol (Pre-Treatment)
Crucial Advice: Porcelain and composite resin do not change colour with whitening gel. If you are planning to have white fillings on your front teeth, we strongly recommend a course of Professional Teeth Whitening before we place the fillings.
The Logic: We whiten your natural teeth to your desired brightness, and then we match the new fillings to that lighter shade.
C. Inlays & Onlays (Ceramic)
For cavities that are too large for a white filling but not severe enough for a crown, we offer Porcelain Inlays/Onlays. These are "jigsaw pieces" of porcelain made in a lab and bonded into the tooth. They are stronger than composite resin and offer superior longevity for back teeth that do heavy chewing.
The "Sensitivity" Myth
A common concern is: Will I have sensitivity after a white filling?
In the early days of composite dentistry, post-operative sensitivity was common. However, modern bonding agents have largely eliminated this.
- Desensitising Protocol: We use glutaraldehyde-based desensitising agents during the bonding process to seal the dental tubules (the nerves) before placing the filling.
- The Bite Check: Sensitivity is often caused not by the filling itself, but by the filling being "too high" (altering your bite). We check your bite with micron-precision paper to ensure your teeth meet perfectly.
If you do experience mild cold sensitivity, it typically subsides within 48 to 72 hours as the nerve settles.
The Investment: Fees & Privilege Access
Quality restorative dentistry takes time. A generic "10-minute filling" often fails or leaks within a few years. We invest the time to layer, sculpt, and polish correctly.
However, we believe that essential health repairs should be accessible. Through our Privilege Programme, we offer these restorations at a rate that rewards your commitment to preventative care.

Longevity: How Long Do They Last?
No dental restoration is immortal. However, the lifespan of a white filling depends heavily on the skill of the dentist and the bite of the patient.
Average Lifespan: A well-placed composite filling typically lasts 5 to 7 years, though many last much longer (10+ years) with good hygiene.
Factors affecting life:
- Bruxism (Grinding): If you grind your teeth, composite can wear down faster than ceramic. We may recommend a night guard.
- Diet: Frequent sugar or acid intake can weaken the bond over time.
- Hygiene: Recurrent decay around the edge of the filling is the most common cause of failure.
The "Repairability" Advantage
Unlike a crown which must be completely replaced if it chips, composite resin is repairable. If a small piece of a white filling chips after 5 years, we can often "sandblast" the area and bond new material to it without removing the whole filling.
Why South Kensington Chooses Us
1. Material Science
Not all "white fillings" are the same. We use premium restorative materials from Japan and Switzerland (such as Tokuyama or 3M Filtek) that are renowned for their polishability and wear resistance. We do not cut costs on the materials that go into your body.
2. The Aesthetic Eye
Matching a single front tooth filling is one of the hardest challenges in dentistry. Our team are skilled colourists. We understand how to blend tints and opaques to make the restoration invisible, even in bright social lighting.
3. The Experience
The sound of the drill is often the trigger for anxiety. We use electric handpieces which are quieter and smoother than traditional air-turbines. Combined with our calm environment, the experience is designed to be as stress-free as possible.
Frequently Asked Questions (FAQ)
Are white fillings as strong as silver ones?
In terms of pure compressive strength, amalgam is very strong. However, composite resin bonds to the tooth, making the tooth itself stronger. Amalgam weakens the tooth structure. For very large cavities, we may recommend a Porcelain Onlay instead for maximum strength.
Do white fillings stain?
High-quality composite is resistant to staining, but not immune. Over years, the edges may pick up pigment from coffee, tea, or smoking. Regular hygiene visits can polish these stains away.
Is it safe to remove my silver fillings while pregnant?
We generally advise deferring the removal of amalgam fillings until after pregnancy and breastfeeding, purely as a precaution. However, placing new white fillings is safe during pregnancy.
Can I eat immediately after?
Yes. Because we cure the material fully with UV light in the chair, it is hardened instantly. You can eat as soon as the numbness wears off.
