What is Tooth Bonding?
Bonding is a process of restoring a tooth to its original shape or making aesthetic changes, such as closing a gap, by applying a white filling material, known as composite resin to the tooth structure. The composite resin blends with the surrounding teeth, making it a conservative option for rebuilding your teeth while conserving the remaining tooth structure, as little or no further tooth structure will need to be removed to allow the composite resin to adhere to the enamel and dentine.
What are white fillings?
White fillings have been an alternative form of filling to the traditional silver amalgam fillings since the 1980s and have the ability to seal and bond to the tooth structure. They can be more insulative than silver fillings, as they do not transmit sudden changes in temperature from hot or cold drinks as the older “metal” fillings do. They also have the advantage of appearing more natural and do not contain mercury which has been a continual controversial health concern surrounding the amalgam fillings as they have been shown to leak mercury vapour over time.
Why have bonding or white fillings?
Bonding or white fillings are one of the best options if you have a chip or fracture that is too large to allow cosmetic contouring to take place. It is an effective way to make discoloured, worn or irregularly spaced teeth look much more aesthetically pleasing and ensure you feel confident in your smile.
However, their primary drawback is that the composite resin used in bonding and white plastic glass mixture used for white fillings can over time become discoloured and stained which may require maintenance and/or repetition of the procedure at regular intervals (every few years) to maintain your new gleaming smile.
