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.

Allergic reactions or persistent pain are rare but manageable with prompt dental care.
