which is the best home remedy for whitening yellowish teeth?

For an at home remedy, try the baking soda and peroxide, but do not leave it on for very long, the peroxide will damage your soft tissue(gums, tongue, etc), just brush normal using these two ingredients and it will help, the baking soda is an abrasive so be careful, and the peroxide over time may make your teeth sensitive, so try it for a week or so and then see what you think, good luck

Try whitening toothpastes. Though heavily advertised, these only partially whiten teeth and don't provide a complete remedy. Make sure the toothpaste has the American Dental Association (ADA) seal of approval and has been clinically proved to whiten teeth effectively. Very few whitening toothpastes have undergone any type of clinical trial, and ones that are too abrasive can damage teeth or make them very sensitive. Get regular dental cleanings, which remove many food and tobacco stains. No amount of cleaning will remove the severe staining left by tetracycline or systemic disease because these pigments lie inside the tooth; you'll have to take more aggressive measures against these. Consider the two options'in-office and at-home treatments'for bleaching your teeth. A dentist performs in-office treatments by coating the teeth with a bleaching agent, then using periodic flashes of light to activate the solution. Treatments last 30 to 60 minutes, and the complete procedure often requires several appointments. In at-home treatments, patients wear a mouth guard fitted with bleaching gel 2 hours a day for two weeks, depending on the severity of staining.

Crest Premium White Strips

Then use Ultrabrite (total whitening) to maintain

Before whitening toothpastes came out I used peroxide and baking soda. It taste gross but it works. Brush gentley and no more than once a day.

Crest Whitestrips. You will have to use them twice a day for 30 minutes each time until your teeth are the shade you want them. This may take several weeks.

Crest Whitestrips, along with a good whitening toothpaste. (Total Whitening is good).

I constantly use the Crest whitening Pre-Brush mouthwash. It works miracles.
