Dental fillings provide solutions for the damaged part of a tooth, and can also prevent further damage (caused by tooth decay, accidents, or other causes) from spreading to the other (healthy) parts of the tooth. The dental filling will also ensure that the form and function of the tooth can be saved, even if a part of the tooth has already been damaged. Silver amalgam fillings have long been considered for dental fillings; however, white fillings have been proven to be safer to use, and provide a more aesthetically pleasing appearance compared to the dark hue that silver amalgam fillings can give to a tooth.
Why Go for White Fillings?
Here are some of the advantages of using white dental fillings, over the ones that are made with silver amalgam:
Improved Appearance – Dental fillings made from silver amalgam are very dark in appearance, and are quite obvious to others when a person opens his mouth. White dental fillings, on the other hand, very closely resemble the appearance of the natural teeth, making the dental fillings discreet or barely noticeable. The white fillings make it possible for patients to have teeth restorations without having to worry about the unsightly appearance of dark-coloured matter resting on their teeth, whenever they smile, speak, or laugh out loud.
Mercury-Free – White fillings do not contain mercury, which is a chemical that can potentially harm the body. Mercury is present in silver amalgam fillings; this chemical component may in time leak into the patient’s bloodstream, causing serious illnesses in the long run.
Less Tooth Structure Removed – The procedure for placing white fillings require a smaller hole – and as a result, less tooth structure needs to be removed – as compared to the placement of silver amalgam fillings.
Better Strength – A tooth’s natural strength can be improved with white fillings, since the filling material firmly bonds to the tooth’s surface. Fillings made with silver amalgam can, in the long run, slowly weaken the tooth – making it more prone to breakage and further damage.
