What it is
A natural repair that bonds to your tooth
A white filling, also called a composite filling, repairs a tooth that has been affected by decay, a chip or wear, using a tooth-coloured material that bonds directly to the tooth.
Unlike older silver amalgam fillings, it matches the natural shade of your tooth and needs less of the healthy tooth to be removed. It’s the material we use for almost all routine fillings at My E20.
How we do it
How we place a long-lasting white filling
In short, we numb and isolate the tooth, remove only the decay, protect the nerve, then bond and build the filling up in thin layers before shaping it to your bite. Here’s what each step involves — and why it matters for how long the filling lasts.
It’s the same treatment you’ll find anywhere. The difference is in how carefully each of these steps is done.
Comfort first
We make sure the tooth is fully numb before we start, and we check with you that it is before any treatment begins. We take our time here, particularly with nervous patients, because feeling rushed is what most people dread about a filling. There's no clock-watching - you set the pace, and we won't begin until you're comfortable and ready.
Isolating the tooth
We keep the tooth clean and dry, often using a soft rubber shield to hold back the cheek, tongue and saliva. Composite bonds to a clean, dry surface and fails on a wet one, so this single step has a big effect on how long the filling lasts. It also keeps everything comfortably out of the way, so the treatment feels more contained and there's nothing for you to worry about while we work.
Removing only the decay
We remove the decayed tissue and as little else as possible, working precisely rather than drilling wide to save time. Preserving the healthy tooth keeps it strong and gives the filling something solid to bond to, which is exactly what a filling needs to last. The more of your natural tooth we can keep, the better the long-term outlook for it - so a conservative hand here pays off for years.
Protecting the nerve
We leave enough healthy tooth between the filling and the nerve, and where a cavity is deep we place a protective lining first to shield it. Get too close and the tooth can become sensitive or need further treatment down the line, so we treat that space with real care. This is one of the details that separates a filling done properly from one done quickly, and it's a big part of keeping the tooth calm and alive afterwards.
Preparing the surface with an etch
We apply a mild acid gel for a few seconds, then rinse it away completely. This micro-roughens the surface on a microscopic level so the filling can grip it - turning a filling that merely sits in the tooth into one that's chemically bonded to it. It's a quick step you won't really notice, but it's fundamental to the seal that keeps the filling in place and stops decay returning.
Applying the bonding agent
We paint on a thin bonding layer and set it with a curing light. This is the glue between your tooth and the composite, and applying it properly is what seals the edge and keeps decay from creeping back in around the margin later. A poorly sealed edge is one of the most common reasons fillings fail, so we take care to get a clean, complete seal right around the repair.
Choosing the right material
Not all composite is the same, and we match it to the job. Back teeth take heavy chewing forces, so we use a stronger, more wear-resistant composite there. Front teeth need a more natural, light-reflecting material that blends with your smile. Matching the material to the tooth - and to the way you use it - is part of making the filling both last and look right, rather than treating every tooth the same way.
Building the filling in layers
We add the composite in thin layers and cure each one before adding the next, rather than packing it in all at once. Placing it gradually reduces shrinkage and stress within the material, which is a common reason rushed fillings fail early or feel sensitive afterwards. It takes a little longer, but building the tooth up in stages is what gives you a filling that's stable, comfortable and shaped accurately from the inside out.
Shaping it to your natural bite
We rebuild the natural cusps and grooves of the tooth and angle the surfaces so it meets the tooth above it cleanly. A filling isn't just about plugging a hole - it has to work with the rest of your mouth. Shaping it to your natural bite gives you a comfortable, even contact that protects the filling from being overloaded, so it isn't taking more force than it should every time you chew.
Checking the bite and polishing
We check how the tooth meets the ones above and below and adjust until it feels completely normal, so the filling isn't sitting high or getting knocked when you eat. A filling that's even slightly too tall wears or chips much sooner, so this final check matters more than it seems. Then we polish it smooth, which helps it resist staining, feels natural to your tongue, and keeps the gum around it healthy.
The detail that makes the difference
The bit that matters happens where you can’t see it.
Most of what makes a filling last happens in details you’d never notice. Dr Gabriel Popescu has a special interest in both restorative and endodontic dentistry — the treatment of the tooth’s nerve. That combination matters here.
A dentist who spends their time saving the nerves of teeth understands exactly how much healthy tooth to leave above the nerve, and treats that margin with care rather than drilling to be safe. He builds each filling up in layers and shapes the biting surface to the tooth’s natural form, bonding across the widest, strongest surface — so the filling feels like part of your tooth and is built to take years of normal use.
