If your teeth are healthy they are yellow

they definitely work but they have been known to cause sensitivity in the teeth and burning on the gums.

it depends on the person so i guess you don't get a straight answer until you try.

they will 100% make your teeth sensitive for a period. 30 minutes, an hour, half a day, it all depends on the person.

White teeth actually aren't healthy and normal, OP. Your teeth should be discolored and a bit yellowed.

>still falling for the white teeth meme

I have yellowish teeth, my dentist says my teeth are perfectly fine. I told him I don't like their color, and he showed me a color scheme of what's considered normal and they're apparently supposed to be yellowish naturally.

That said I asked about whitening and he said it's not worth it unless I am going to be going on TV or something similar.

I still can't help but feel self conscious by it considering the fact every fucking person I see out seems to have perfectly white teeth.

My ex gf tried these and she said it didn't work

shit works. when you're using them you'll want to spit alot since you can't swallow any of it.

I've never had any problems. the enamel MIGHT get more see through. but it's been years since I've used them.

I have a box ready to go.

use it until you see it fucking you up.

used them, they make them whiter but they do make your teeth more sensitive. once a day for 30 minutes doesnt make them unbearable sensitive but it is noticeable

I used a box of the Professional White, ordered from Amazon on sale, worked great

Used them before. Sensitive during treatments to the point of painful throbbing, but I have sensitive teeth to start with. Cleared up a day or two after I finished tho. I'm a daily coffee drinker so I didn't see as much improvement as I would have liked but still noticeable. I used the 3d white toothpaste and mouthwash at the same time. Not sure if necessary, but I wanted to keep my bases covered.

Not sure what he's talking about, you can totally swallow when you're using them.

Also experienced gum burning towards the last few days of treatment.

Your teeth will be sensitive but once you're done it's over.

Your teeth won't be "permanently" sensitive like a lot of virgins say.

Once you're done turning them white, all you need is whitening toothpaste to keep them white (which doesn't even cause sensitivity because of how diluted it is).

i just used them on my top teeth since I chipped a bottom tooth and it would hurt to put the bottom layer on. Got lots of compliments on my white teeth whilst using them
