As a kid i didnt take care of my teeth very often, as a result

Gargle with hydrogen peroxide once a day for 1 minute before brushing.

Cut down on acids/coffee/tobacco.

You're welcome.

Can't change it now without whitening, which can actually do some damage to the integrity of the teeth

I have the same issue. I went to see the dentist about it and he said to drink fizzy drinks with a straw only. Makes sense, because I used to hold them in my mouth for several minutes before swallowing. Now I use a straw all the time, and it's not getting any worse.

Problem is girls notice and I have to explain it's not plaque but staining

unfortunately its hard to undo damage when its done. this isnt like you got some gunk on your teeth this is like leaving your shirt in bleach for a few years then wondering why you can't get the color back. it doesn't exist.

you can go to your dentist and pay to have it whitened, this is standard procedure after braces as you tend to get some yellow regardless of how hygenic you are when you wear those.

Don't do it daily, just once a week is enough. I read somewhere that it destroys healthy bacteria or something in your mouth if you do it all the time.

I also brush with baking soda 2-3x a week and use whitening toothpaste and my dentist considers my teeth A1 shade. They used to look like butter.

those whitening strips make a noticeable difference. they have long and short term plans and the only inconvenience is the extra sensitivity during its use.

If you do it for a long period of time, yeah, once a day can hurt your gums. If you're going to do it for a long period of time, you should dilute it by 1/2 with water.

Baking soda also does help.

Yeah you're just kinda fucked. They're stained. Like any other stained thing, you're gonna need to break out the heavy duty shit to fix it.

But as stated before, you also risk just damaging your teeth even further. I tried whitening and it thinned my enamel so much it made everything painful as fuck, to the point I almost couldn't eat.
Give it a shot, but quit if your teeth start to hurt.

I would advise against using hydrogen peroxide.

It increases your chance of developing oral cancer greatly, damages the gums, tastes terrible, and disturbs the bacterial cultures in your mouth greatly.

I would just suggest using a good non-alcohol based mouthwash for a few minutes every other day or so. A lot of them contain chlorine which will do a great job of bleaching your teeth, and some even re-mineralize teeth which strengthens them.

If you do insist on using peroxide, I would only use it once a week, and in solutions weaker than 2% h202pv.

Like the $5 ones at the pharmacy?

I've got horrible teeth.

I've just learned to live with it. I don't smile any more.

They're usually more expensive than that...like $30+ at least.

You know you can get mouth pieces molded to your teeth that just apply it to the tooth surface right?
