Cosmetic Dental Treatment: Laser Teeth Whitening
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.
The Laser Whitening Procedure
The in-office laser whitening procedure is a simplified, less messy alternative to brightening your smile using traditional tray delivery systems. No longer do you have to wait weeks for results or wear those uncomfortable trays for extended periods of time. The process takes about 2 hours to achieve the desired results. While relaxing in one of our comfortable dental chairs, the teeth to be whitened are isolated with barrier control solutions, and the whitening gel placed. The Zoom “laser” is placed into position and activated. The photo initiators contained in the whitening gel are activated with the use of the laser, and the process begins. The whitening gel is removed and re-applied for up to three sessions. Each session lasts approximately 20 minutes. Once complete, all the barriers and solutions are removed and rinsed clean.

Teeth Whitening FAQ
Studies have shown teeth whitening to have no adverse effect on tooth enamel. During the whitening process, enamel pores are widened and this can cause sensitivity to hot and cold, but this effect will last only one or two days.
HOW LONG DOES THE WHITENING LAST?
Food and drink will cause teeth to discolour again over time, avoiding red wine, coffee, tea and smoking will help preserve the results. Typically patients can expect results to last one to two years before another whitening treatment is required.
HOW ARE DENTAL WHITENING PROCEDURES DIFFERENT FROM OVER THE COUNTER PRODUCTS?
Whitening toothpastes and other products found in stores only clean stains on the surface of teeth. Dental laser whitening changes the tooth enamel colour, for dramatic results.
