Many adults have silver amalgam fillings placed years ago. They can be durable, but they are visible when you laugh, and old fillings can crack or leak. Tooth-coloured fillings and restorations offer a more natural look. But should you replace fillings that are still working?
Replacement is usually recommended if a filling is cracked, leaking, has decay underneath, or the tooth around it is fractured. Cosmetic replacement of visible fillings is also a reasonable choice when discussed with your dentist.
Health authorities consider amalgam fillings safe for most people. Removing healthy fillings purely for safety reasons is not usually recommended, as removing them also removes some tooth structure.
Composite resin fillings are bonded to the tooth and blend in naturally. Larger restorations may be replaced with ceramic inlays or onlays, which are strong and stain resistant.
The old filling is removed carefully, any decay is treated, and the new restoration is placed and shaped. Small fillings are usually completed in one visit; inlays or onlays may take two.
Brush and floss regularly, limit sugary snacks, and attend regular check-ups. Composite can stain over time, so polishing at hygiene visits helps keep it looking fresh.
Old fillings can deteriorate without causing pain. Signs that a filling may need replacing include visible cracks, dark staining around the edges, sensitivity to hot, cold or sweet foods, food getting trapped, a rough or sharp edge, or a filling that feels high when biting. Your dentist may also detect problems on X-rays, such as decay underneath the filling. Large old fillings can weaken the tooth over time, increasing the risk of cracks. Regular check-ups allow your dentist to monitor fillings and recommend replacement before more significant damage occurs.
Composite fillings are placed directly in one appointment and bonded to the tooth. They are suitable for small to medium-sized cavities and can be repaired easily. Ceramic inlays and onlays are made outside the mouth, either in a laboratory or using digital milling, and bonded in place. They are more durable and stain resistant, making them a good choice for larger restorations. Your dentist will recommend the best option based on the size of the filling, the amount of remaining tooth structure and your bite. Both options provide a natural, tooth-coloured appearance.
If you have several old fillings, you do not need to replace them all at once. Your dentist can prioritise fillings that are failing or causing problems, and schedule cosmetic replacements over time to suit your budget. Replacing fillings gradually also allows you to see the results and decide how many you want to change. If you are planning other cosmetic treatments, such as whitening or veneers, your dentist will help coordinate the sequence. A personalised plan ensures that each step contributes to a healthy, natural-looking smile without unnecessary treatment or expense.
Replace them if they are damaged or if you want a more natural look after discussing it with your dentist.
