White fillings use a mixture of powdered glass and tooth-coloured resin to repair a decayed or damaged tooth. Amalgam fillings use a silver-coloured mix of metals and are not as aesthetically pleasing as their white counterparts.
White fillings are great for people who have metal allergies. If you have very sensitive teeth, white fillings are an excellent alternative to amalgam. As it is a metal, amalgam can expand or contract when exposed to hot or cold food and drink. Resin does not react to changes in temperatures. White fillings preserve more of the tooth’s structure as the dentist layers the resin, encouraging a stronger bond and providing better support for the remaining part of your tooth.
In contrast to amalgam (silver) fillings, white fillings require less preparation and, thanks to modern developments, can be used for back and front teeth alike. You’ll also be able to smile and open your mouth with confidence, knowing your filling blends in with your existing teeth.
