    Illustrative discussion of a filling using a teeth model in a bright treatment room

    A filling repairs a tooth affected by decay, helping restore its shape and function. We’ll assess the area and discuss suitable materials, including tooth-coloured options, taking account of the tooth’s position, the extent of the damage and your bite.

    Clinically reviewed

    A filling repairs a tooth affected by decay or damage. The affected material is removed, the area is cleaned and a filling is placed to restore the tooth’s shape and function.

    It may be a suitable option. The choice depends on the tooth’s position, the size of the repair and your bite. We’ll explain the materials and costs before treatment.

    Not automatically. A healthy filling may not need replacing. Your dentist will check it and explain if there is a clinical reason to repair or replace it.

    This varies with the size and location of the filling, your bite and oral care. Regular check-ups allow us to monitor it and identify wear or other concerns.

    Some sensitivity can occur. Contact us if it persists, gets worse or the bite feels uncomfortable so your dentist can check the filling and advise you.

    White composite fillings are matched to your tooth colour and bond to the tooth. Silver amalgam fillings are durable but more visible. Your dentist will explain which materials are suitable for the tooth, the size of the repair and your bite.

    Amalgam is considered safe for most adults, but it isn't suitable for everyone. It is not normally used for children under 15 or during pregnancy or breastfeeding unless there is a specific clinical need. Your dentist will explain the materials appropriate for you.

    Local anaesthetic is used for many fillings. Numbness often lasts around 2–4 hours, although this can vary. Avoid chewing and hot drinks until it wears off so you don't accidentally bite or burn yourself.

    Composite fillings set during the appointment, but wait for any numbness to wear off before eating. With amalgam, your dentist may advise avoiding hard foods on that side for 24 hours. Follow the aftercare instructions for the material used.

    Decay can develop without pain, especially before it reaches the inner part of the tooth. Treating it earlier can help limit the size of the repair and avoid more extensive treatment. Your dentist will explain the findings and why a filling is recommended.

    Not always. Very early damage before a cavity forms may be managed with fluoride, improved cleaning and changes to how often you have sugar. Once a cavity develops, a filling may be needed. Your dentist will assess how far the decay has progressed and explain whether prevention, monitoring or treatment is appropriate.

    Yes. Decay can develop around the edges of a filling. Brush twice a day with fluoride toothpaste, clean between your teeth and reduce how often you have sugary foods and drinks. Regular check-ups help us monitor the filling and surrounding tooth.

    Contact the practice for an appointment and keep the area clean. Ask your dentist whether a temporary filling material from a pharmacy is suitable until you can be seen. If you have significant pain or swelling, seek urgent dental advice rather than waiting.

    For larger repairs, your dentist may discuss a lab-made inlay, onlay or crown. These can be more suitable than a large filling, depending on how much tooth remains and your bite. We’ll explain the suitable options and costs before treatment.

    Yes. Baby teeth can be filled when appropriate. Your dentist will assess the tooth and discuss suitable care. Preventive options such as fissure sealants and fluoride varnish may also help reduce the risk of decay.
