i have no idea how to use baking soda?
a chemical right? not for baking cakes right?

i believe soda can clean for a month/2-3 weeks and you will get stains back right?

There is already a type of toothpaste that contains baking soda, have you tried that? You just use baking soda powder? I know you can buy as much as you want at Save-on foods.

cinderelly

from what i've read. you just use regular baking soda to brush your teeth. the kind used for baking

tequila

cinderelly

I used Crest Whitening Strip and it worked.  But I am forgetful and lazy sometimes and didn't use it everyday, but it still worked.

i just went to the dentist yesterday... they said crest whitening strip is the best.. but because of a certain chemical that makes the strips, so if you use it too much it's not good for your teeth

i work at a dental office, whitening strip is the best and the cheapest according to my dentist boss... but it doesn't last very long.

saw something like this online, i wonder if it really works lol

七招讓牙齒快速變白

1、家裏的食醋(陳醋，白醋都可以，但是不可以是醋精)含在嘴裏1分鐘到3分鐘,然後吐掉，刷牙。效果非常的好!但是就是牙齒會覺得非常的酸，麻(感覺會持續2分鐘左右)不能連續，經常做，大約2個月左右做一次，就好了。否則對牙齒不利，是有緊急情況的時候，可以救急的方法(如出門約會前，發現牙齒好黃)，恩，並可以除口臭：)  

　　2、把桔子皮曬乾，磨成粉，和牙膏混在一起刷牙，牙齒很快就可以白  

　　3、這種辦法需要用到草莓和發酵粉（家裏沒有發酵粉，用蘇打粉也可以），然後把草莓放在碗裏（只需一個草莓就可以），在碗里加上兩勺發酵粉，然後搗成泥狀，用牙刷沾著刷牙，持續5分鐘，也可以使牙齒變白！這種方法很實用，堅持這樣可以長久性的使牙齒亮白，但是不能天天用，一週一次就可以了。

　　4.可將明礬研細末，用明礬面刷牙，連刷十至二十天，達同樣效果。  

　　5、每晚在刷牙後，用紗布沾些檸檬汁，摩擦牙齒，牙齒就會變得潔白光亮。 檸檬的洗淨力強，又有潔白作用，且含有維他命C，能強固齒根。  

　　6、把生花生嚼碎，不要吞下去，拿花生屑當牙膏刷牙，可以讓牙齒變白  

　　7、用墨斗魚的骨頭，碾碎放在牙刷上當牙膏使用，立杆見影(墨斗魚就是墨魚，烏賊。它身體有塊大骨頭，是白色的，用指甲刮一刮，能出來很多白色粉末，把這些粉末當牙膏用，可使牙齒變白)

surface stain you can remove by normal brushing....baking soda helps by acting as a abrasive
the strength of the strips are so weak that it can only bleach the surface stain

if the stain is deep inside the teeth.....go see a dentist
