Okay to wear retainer after teeth whitening?

Based on what you've reported, I would definitely recommend that you wear your retainer.  You may need to just purchase whitening refills from your dentist and whiten your teeth more frequently, like every 3-5 months.  I recommend wearing your retainer because you would hate to have your teeth shift and end-up having to pay for orthodontics again, later on down the road.  Good luck and I hope this helps.

Hi, the retainers are normally not the cause of staining. As you have gathered from previous answers, it could be due to some diet or rarely any enamel decalcification leading to staining. Also check that your gums are not receding due to prolonged retainer wear. This can lead to root exposure which is less white than tooth enamel.

Your dental retainer should have absolutely no effect on causing any stains to your teeth.  I doubt very seriously if your retainer caused your teeth to stain.  Is that what your dentist or orthodontist told you?It is okay to continue to wear your retainer unless directed otherwise from your dentist or orthodontist.Regarding external staining, most often it can be attributed to oral hygiene or certain foods (curry sauce, soy sauce, red wine, berry juice, etc.) or smoking.
