Question:

Tooth whitening only keeps the teeth white for a few days? Why?

I leave the tooth whitening gel on for half an hour (both the 5 minute kind as well as the 30 minute kind) The teeth look a few shades whiter, but within 2-3 days to a week, the teeth are as yellow as straw again, and I'm whitening every week or sooner ? Is this normal?

  1. yes because tooth whitening is just a topical agent...therefore..all your doing is whitening your teeth on the top..and it wont last..which means you will have to continue the use...best bet..have a dentist office do it.


  2. I suggest you get your teeth whitened professionally if you want lasting results.  I had Zoom whitening done over 5 years ago and my teeth are still so white and beautiful.  I think they guarantee their work for 3 years, but mine has lasted much longer.  Also, if you use the take-home stuff avoid eating/drink dark sodas and foods.  Use a straw whenever necessary.  Those items really harm the color of your teeth.

  3. quit drinking soda and eating things that stain your teeth. AND SMOKING for sure.

  4. Ask your dentist.

  5. You might want to try a more powerful tooth whitener. Your dentist can help choose which tooth whitener is best for you. Also you might want to brush your teeth more often if possible.

  6. yes

  7. I use Crest white strips premium and it lasts for a few months. Consider if you are eating foods that stain your teeth, or drinks such as coffee or cola, smoking also yellows the teeth. Are any of those things a factor?

  8. I would ask the dentist about it.

    If nothing else, look into bleaching at the dentist office or ask for gel. The bleaching gel the dentist gives you is always stronger than store-bought brands.

  9. Yes it is normal, your teeth are obviously naturally a shade of yellow.  All teeth are not naturally "hollywood" white, they are different shades of off white.  

    I have the same problem, although my yellow teeth was caused by 34 years of tea drinking in England I had them professionally whitened in the USA about 3 months ago.  They are now starting to come back to a yellow shade even though I brush 4 times a day, here's my routine for trying to whiten them, arm and hammer baking soda and peroxide, I use pure baking soda after drinking coffee (i no longer drink tea as the tannin will stain your teeth), I then use a tooth sensitive paste.  Then I will use whitening strips or whitening gel with a mould.  

    Still yellow.  after 6 months of this routine, $400 in pro teeth cleaning with Zoom whitening, baking soda, whitening products, strips so I am realising that hollywood has again warped our view of the body, yellowish teeth are natural people!  Hollywood and CNN actors use veneers which are basically plastic strips which goes over the teeth to create the s****. illusion that they are better than everyone else.

    YELLOW TEETH ARE FRICKIN NORMAL!!!!!
