The way in which your period may affect your teeth and gums are quite varied.
You could find that days leading up to the start of your period that you experience increased soreness in your mouth your gums may swell and bleed. This is caused by increased amounts of hormones such as estrogen and progesterone in your body as well as a build-up of plaque.
On the other hand, you may find you experience little to no ill-effects at all.
However your mouth reacts to your period, the best advice is to keep brushing and flossing as normal, this phase will pass as long as you are continuing with your home care.
If you’re on oral contraceptives (“the pill”), which contain progesterone, you may find that the increased levels of the hormone in your body trigger the same kind of gingivitis often seen in pregnant women. Known as “pregnancy gingivitis”, it’s marked by swelling and redness, caused by increased blood flow to the gums. It will be pronounced in the first few months after you go on “the pill” and if it worsens, consult your GP and your Dentist.
Always make sure you tell your dentist when you’re using contraceptives.
