Later, William Add made a toothbrush in 1780 in England with bone and horse hairs. On those days, brushing the teeth was not a common habit except for the elite people who could afford to buy a tooth brush. Then after the invention of Nylon in 1938, the modern day toothbrushes started coming into the market.

... techniques for teeth whitening and laser teeth whitening is the last one in that series.

In laser teeth whitening, a bleaching agent will be applied over the teeth and it will be exposed to the rays from a laser gun. The heat and the light of laser rays will perform as catalysts to fasten the chemical reaction between the chemicals contained in the bleaching agent and the outer surface of the teeth. Thus you will get immediate result.

Although, the modern techniques are found to be safer and hazard free, still there are some concerns about them. Allergic effect of the chemicals contained in the whitening agent is one among them.
