A cavity left untreated will only cause more pain, sensitivity, and disruption to daily life. Fillings restore your ability to chew, bite, and speak comfortably — often in a single appointment at our St Helier practice. For most patients, it's one of the most immediately rewarding treatments we offer, with relief felt from the very same day.

Sealing a cavity prevents bacteria from spreading deeper into the tooth, protecting against more serious infection, nerve damage, or the need for root canal treatment further down the line. Catching and filling decay early is one of the most cost-effective things you can do for your long-term dental health — and it's exactly why regular check-ups matter.

Modern composite fillings are matched precisely to the shade of your natural teeth, making them virtually invisible once placed. Whether you're having a new cavity treated or replacing old metal amalgam fillings, the result is a seamless, natural finish — no dark patches, no visible metalwork, just your smile as it should look. It's a small change that makes a noticeable difference.

We know that fillings carry a certain reputation — but the reality at New Street Dental is far more straightforward than most people expect. Treatment is carried out under local anaesthetic, is typically completed in one short visit, and our friendly St Helier team will make sure you're comfortable and informed every step of the way. Many of our Jersey patients are pleasantly surprised by just how easy the process is.

There may be mild discomfort or sensitivity to hot, cold, or pressure may occur for a few days post-treatment.

Over time, fillings may wear down or chip, requiring replacement.

If decay is extensive, there’s a small risk of needing additional treatments, such as root canal therapy.

While modern dental procedures are incredibly safe and highly successful, all medical and dental treatments carry a minor degree of risk. Rare complications—such as allergic reactions to materials or anaesthetics, or persistent, lingering pain that doesn’t fade—can occasionally occur. However, these issues are uncommon and entirely manageable with prompt professional dental care.

Fillings at New Street Dental are capped at £98, so that's the most you'll pay for a single filling here in St Helier. Your filling is tooth-coloured composite, matched to your natural shade, and in most cases it's done in one visit under local anaesthetic. We'll always confirm the price with you before we start, so there's nothing unexpected.

Most practices vary the cost of a filling depending on the material, the size, and which tooth it's in, which is why quotes elsewhere swing so widely. We keep it straightforward: no single filling costs more than £98. If you need more than one, each is still capped at that same price, so you can plan for the treatment with total clarity.

We use tooth-coloured composite fillings rather than the older silver amalgam. Composite bonds directly to the tooth, which lets us preserve more of your natural structure, and it's colour-matched so the repair is virtually invisible once it's in. Amalgam is the traditional silver material you'll remember from years ago, but it's increasingly being phased out. If you have old metal fillings you'd like replaced with a natural-looking finish, that's something we're happy to help with.

The sooner a cavity is treated, the cheaper it stays. A small filling caught early keeps the problem to that one straightforward visit, whereas leaving it risks the decay spreading to the point of needing root canal treatment or a crown, both of which cost considerably more. A routine check-up is £35 and is the simplest way to catch these things early. To book a filling or an examination, call us on 01534 500095.
