Yellow teeth can be caused by various factors such as smoking, coffee stains, and food residue that sticks to the teeth. However, this condition can be overcome by using toothpaste that contains whitening agents. However, it is important to remember that toothpaste cannot whiten teeth and can only brighten them. If you want to have white teeth, actions such as bleaching with hydrogen peroxide or veneers need to be taken.

Choosing toothpaste with the right content can help brighten teeth or restore natural tooth color. To avoid making the wrong choice, here's how to choose the right toothpaste to brighten teeth.

The following is an example of a bleaching agent that can remove yellow color on teeth: Hydrogen peroxide, Titanium dioxide, Zinc oxide, Magnesium oxide, Calcium oxide, Aluminium oxide. These ingredients can only be used to whiten yellow teeth caused by food stains. If you are a smoker, consider toothpaste with charcoal or mineral clay content.

Xylitol has been proven effective in inhibiting bacterial growth. You may find toothpaste with xylitol on the market, although xylitol is usually found in gum and released gradually. One example of gum commonly used in toothpaste is cellulose gum.
