Fillings are a type of dental restoration used to restore broken, worn and decayed teeth.

If your dentist advises you that one or more of your teeth requires a filling you can be assured, at GB Dental we use the best equipment and materials to make sure your restoration is strong and durable.

GB Dental has not used amalgam (silver) fillings for 20 years. Amalgam is made from a mixture of silver alloy and mercury and can stain teeth over time, giving teeth a grey or dark appearance.  As metal can expand over time, amalgam fillings can slowly weaken the tooth eventually leading to cracks and fractures in the tooth.  There is no good scientific evidence to show that having amalgam fillings in your mouth causes toxicity, however if you are interested in having your amalgams replaced with a different filling material, please talk to your dentist at your next visit.

At GB Dental, we use composite resin (white or tooth-coloured) fillings.  A composite resin is essentially a monomer filled with tiny particles for strength that is set (hardened) by a light with a specific wavelength.  They have the advantage of requiring a more conservative tooth preparation (less drilling required), and are very aesthetic, blending seamlessly in with your natural tooth. 

GB Dental uses Estelite composite, a multiple award-winning material that ensures exceptional results, with a highly polished and durable finish. 


What is involved when having a filling?

Your dentist may or may not use local anesthetic to numb the area being treated, depending on the size and position of the filling, and your preference.  If a local anaesthetic is required, we will always use a numbing gel first to reduce the discomfort of the injection. We also have ‘Happy Gas’ (nitrous oxide) available which allows you to feel relaxed and can help with any anxiety during your procedure or application of local anaesthetic.

Treatment for a filling involves removing the damaged tooth structure then your dentist will prepare the space for the filling with materials to help the composite bond to your tooth. 

The composite is applied to the tooth in layers, then a special blue light cures (hardens) the material. When the process is complete, your dentist will shape and adjust the filling to your bite and then polish the final restoration.

Fillings for children

Baby teeth are important for speaking, eating and keeping the necessary space for when their adult tooth come through. Some baby teeth stay in your child’s mouth until they are 13 years old.

Should your child require a filling, all our dentists are highly trained in children's dentistry, so you can feel reassured your child will be in great care. 

Your Dentist can give you any advice about your child’s baby teeth that should be filled and baby teeth that should be left to fall out for the tooth fairy.
