What are teeth whitening pens ?
Teeth whitening pens are plastic tubes which has the average length of a pen and looks like a lipstick pencil . Once you remove the cover you would see a brush which overlay the small opening of the pen . The pen houses a gel which we rub onto our teeth to remove visible stain .
What are ingredients in a teeth whitening pen ?
The active ingredient in teeth whitening pens are either hydrogen peroxide or carbamide peroxide a few brands use sodium bicarbonate. Other ingredients may be glycerin,water,carbomer,flavouring agent,carbinol and sodium hydroxide .
Hydrogen peroxide gel is the active products preferred and used by dentist for effective teeth whitening. The disadvantage is that it can cause gum irritation and tooth sensitivity if not used correctly or the concentration is too strong .
Many most home teeth bleaching products active ingredient is carbamide peroxide .Carbamide peroxide is made from hydrogen peroxide and urea is added to it . Carbamide peroxide takes a little longer than hydrogen peroxide to clean your teeth because it has to break down to hydrogen peroxide to start working but it’s less harsh on your teeth and gum . There is a 3:1 ratio of carbamide peroxide so 16 % hydrogen peroxide is equivalent to 48 % carbamide peroxide . The advantage carbamide peroxide has it that it’s good to use for longer periods on your teeth for example if you want to wear a teeth tray.
The other active ingredient in sodium bicarbonate also known as baking soda . This best for those people with sensitive teeth and gums. Research has shown that this abrasive compound of baking soda removes superficial stains but not very effective on deep stains.
