Also known as composite resins, tooth coloured fillings are sculpted onto your teeth for a flawless look. A mixture of acrylic resin, fine glass and silicon particles white fillings are sculpted and polished to match your surrounding natural teeth for a beautiful, complete smile.
The strength and natural appearance of tooth coloured restorations makes them a popular option, which can be completed in a single visit. There are a number of differences between traditional amalgam fillings and modern white fillings. For example:
1. Amalgam fillings required part of your tooth to be drilled: white fillings do not.
White fillings involve the cavity in your tooth being cleaned out and filling with a composite resin. This is then shaped and polished to blend in with the rest of your teeth.
2. Amalgam fillings could crack your teeth as they expand and contract with extreme temperatures: white fillings do not.
Amalgam expands and contracts with the heat and the cold, which has been known to crack teeth. If the crack is only above the gum line a dental crown can save the tooth. However, if the tooth cracks below the gum line and the root of your tooth is badly affected then unfortunately extraction may be required.
3. Amalgam fillings do not comprehensively protect your teeth: white fillings do.
With amalgam fillings bacteria can get underneath an amalgam filling and cause further tooth decay. However, with white fillings the cavity is completely filled and protected. Of course this does not mean that that tooth is now impervious to decay.
Inlays and Onlays
Inlays and onlays are a natural looking alternative to fillings. Made from porcelain for strength, they are custom made to fit and fill most types of cavities, and are almost impossible to distinguish from your natural teeth. Inlays and onlays use a precise replica of your tooth, made from a moulded impression.
Inlays and Onlays are restorative treatments that are stronger than a filling but not as strong as a dental crown
Unlike conventional fillings, which require the removal of large amounts of healthy tooth, only the damaged portion of the tooth needs to be removed. Once placed, they are virtually undetectable in the mouth and they preserve much more of your natural tooth structure than standard amalgam fillings.
Usually taking two appointments to complete, inlays and onlays look exactly like the rest of your tooth, and are so durable that they need not be replaced for many years.
