The “secret” to success using a teeth whitening pen is pretty simple – it is really convenient and you save much time this way, because a teeth whitening pen can be used for only a single minute every twenty-four hours. It is also very affordable and cost effective – every teeth whitening pen contains teeth whitening substance, called whitening gel. Whitening gel is really important because the concentration of the oxidizing agent it contains can easily damage your enamel and severely increase the sensitivity of your teeth. If this happens you will most likely feel serious pain every time you drink or eat something hot. The recommended concentration is between 12 % and 20 % hydrogen peroxide – this oxidizing agent, once in contact with your enamel, is absorbed deep in it and accordingly destroys food stains on the dentin.
Teeth whitening pens are really cost-effective. They contain teeth whitening gel, which you need to apply regularly to your enamel, but they are also pretty easy to use because the only thing you need to do is to take your teeth whitening pen and squeeze it or rotate the plastic part on the bottom of the product so that some gel is dispensed. You should then just apply that gel to your tooth enamel and after a couple of minutes you will probable be able to notice the first results. It is really important that you don’t eat or drink after having used the teeth whitening pen. In case you do this, you will ingest the applied whitening gel, which should not happen because of its ingredients and what is more, you will reduce the efficiency of the teeth whitening process. So, once you have applied some gel you should wait for a minute or two and be careful not to let your tongue get close to the front surface of your teeth, where you have applied the teeth whitening gel.
Teeth whitening pens are really simple and that is the main reason why they are so cost-effective. You can use a single teeth whitening pen for a month, but if you use it the right way you can achieve a shiny white smile for only a couple of weeks.
