Over time, teeth naturally change colour, usually darkening or yellowing as we age. Tooth colour is affected by a number of factors, including consumption of food, drink, and tobacco products. It can be difficult to determine the best and safest treatments for whitening teeth. We don’t recommend store-bought products such as whitening toothpastes and white strips because most products scrub off the tooth enamel in order to achieve the whitening result – this can be dangerous for your dental health in the long run. Furthermore, the results will generally be slight, so these products are not recommended for patients seeking a dramatic improvement. Professional whitening treatments that take place in the dental office reach below the tooth’s surface, for a more dramatic, lasting result.
