Why do teeth turn yellow?
As a person gets older, the white enamel wears away. When this happens, the calcified tissue will begin to show through underneath. This tissue is called dentin and is yellow in color.
- Teeth can turn yellow for the following reasons:
- Compounds that discolor the surface
- Plaque formation gives a yellow tinge
- Enamel wears off and dentin comes through
The latter cause is difficult to prevent as it is a natural part of the aging process. However, staining can be reduced by avoiding:
- Coffee
- Red wine
- Beetroot
- Blueberries
- Smoke
- Chewing tobacco
Here are 5 natural remedies that can help get rid of yellow teeth at home. These are an alternative to teeth whitening options that a dentist can offer:
1. Baking soda and hydrogen peroxide
There are several different options for teeth whitening that can be tried at home or offered by dentists.
Using a toothpaste that contains baking soda and hydrogen peroxide can help reduce the yellowing of your teeth.
It is possible to make a paste at home by mixing 1 tablespoon of baking soda with 2 tablespoons of hydrogen peroxide.
2. Vitamin C
A 2007 study found that vitamin C deficiency can worsen periodontitis, which is a buildup of bacteria on your teeth and gums. This build-up contributes to the discoloration.
It follows that replenishing with vitamin C can reduce tooth discoloration. More research needs to be done on whether taking vitamin C can have a whitening effect on teeth.
3. Fruit enzymes
When added to toothpaste, certain fruit enzymes can fight discoloration.
A 2012 study found that toothpaste, which contains papain enzyme from papaya fruit and bromelain enzyme from pineapple, helps remove tooth stains.
4. Apple Cider Vinegar
When used in small amounts, apple cider vinegar can reduce tooth discoloration and improve whiteness.
A 2014 study found that apple cider vinegar had whitening effects on teeth. However, it should be noted that this was a study on animals.
Apple cider vinegar can damage the tooth surface if used too often. More research is needed into using apple cider vinegar as a tooth whitener. In the meantime, it should be used sparingly and with caution.
5. Coconut oil pulling
A 2015 study found that oil pulling or mouth rinsing with coconut oil could be an effective way to reduce the buildup of plaque on teeth. Since plaque build-up can contribute to the yellowing, pulling coconut oil can reduce the discoloration.
