Taking certain medications, treatments and being ill can also affect the color of your teeth.

However, whitening kits including strips and teeth whitening gel can do a considerably well job.

They are better at removing stains accumulating on your enamel.

These form because of eating and drinking foods that discolor the shade of your teeth.

Regular smoking can turn your teeth into a dark yellowish or brown shade.

Strips containing gel can usually get rid of these stains and show a considerable difference in the shade of your teeth after using them constantly for 2 weeks.

The results can last as long as 4 months.
