Today, I decided to try whitening my teeth for the first time. I applied the strips to my teeth and decided to lay down and wait for the thirty required minutes to pass. I accidentally fell asleep and woke up three hours later. My teeth are still in excruciating pain and are covered in white streaks. FML

Last call, bad decisions and 3 a.m. texts you'll regret until noon. Cheers.

I remember how the pamphlets that came with my curling irons always had a warning in them along the lines of, "Do not use while asleep!" You're going to be the reason why this warning appears on the whitening strips' literature in the future! Ouch.

As the hydrogen peroxide oxidizes the colorants in the dentin layer of the tooth (in other words, as the whitening gel does its job), it incites a pulpal (tooth nerve) response. This is the sharp pain you may feel. Most whitening strips that you can take home and use are not too concentrated... probably 15%. The OTC stuff might be even less. The 35% concentration should only be used for 30 minutes but the 15% concentration instructions actually say you can sleep with them in. And even if you are awake, you can keep them in for up to 3 hours. The OP should brush their teeth to remove the remaining gel. The sensitivity *should* disappear within an hour or so.

Rinse your mouth (teeth) with fluoride or rub fluoride on your teeth twice a day. Sensitivity should start to wain.

When my patients get sensitivity from bleaching or whitening strips, I normally advise getting some sensodyne, rubbing it on the teeth and leaving it in for about an hour. Do this every day over the course of a week and that should resolve the sensitivity.

If you had watched the Friends episode or the NCIS episode where this happens you would have known not to go lie down.

This reminds me of the episode of Friends where Ross whitens his teeth before a date for too long and they end up glowing in the dark

That really sucks. Love the screen name though.

At least it worked... Partly

Ross? Is that you?

did you sleep through the alarm you set?
