Gel Application. 

For better results after thoroughly drying the teeth, express a small ‘dab’ of whitening gel onto the centre each tooth.

Less is more effective than thicker layers.

Then, avoiding gums spread the gel evenly over each entire tooth with a whitening gel applicator tool. Apply gel to each quadrant consecutively, 4-5 teeth at a time.

This will ensure a thin shiny layer of gel covers each tooth.

This method is faster, and avoids uneven layers of gel, which reduces the amount of gel required.

It also, limits the risk of gel getting onto gums..
