If you have a cavity in your tooth, our dentists will probably recommend placing a filling. There are different types of filling, and in most cases, we recommend tooth-coloured fillings.
About tooth-coloured fillings
Tooth-coloured fillings, also known as white fillings, are an effective, aesthetically pleasing means of protecting your teeth and preventing the spread of infection when a cavity, a hole, forms. If you have a cavity, there’s a risk of bacteria spreading to other parts of the tooth, and this can increase the risk of infection and further damage. White fillings offer an alternative to mercury amalgam fillings, which are becoming less popular.
The benefits of tooth-coloured fillings
Tooth-coloured fillings are becoming more commonplace due to their aesthetic benefits, but also as a result of concerns about the safety and environmental impact of mercury fillings. Tooth-coloured fillings are virtually invisible when you smile, unlike amalgam fillings, and they’re also safe and more eco-friendly.
How is a filling placed?
If you need a new filling, or you’re having an old filling replaced, your dentist will explain exactly what is going to happen before administering local anaesthetic to numb your tooth and prevent any pain. Once the cavity is clear of any old fillings or debris, the tooth will be cleaned thoroughly, and then a bonding agent will be applied. This will help the composite material to stick inside the cavity. The composite, which is matched to your natural tooth shade, will be poured into the cavity and then shaped to ensure a snug fit. Your dentist will then shine a curing light onto the tooth and this will set the filling. The final step is to carry out any final adjustments to make sure the filling fits the cavity perfectly. Placing a filling should take less than an hour.
