Why are your teeth yellow even when you brush them every day? Here are some common reasons:
- Genes (e.g. if one of your parents’ teeth are yellow, yours might be too)
- Enamel is already thin (yellow dentin starts to show more)
- Wear and tear as well as teeth grinding (results in thinning of enamel)
- Smoking (nicotine can cause yellow or brown stains on teeth)
- Stain from coffee, tea, wine and certain sauces and spices
- Antibiotics (can lead to permanently stained teeth)
- Excess fluoride
- Physical impact to the teeth (discolouration because of bleeding)
To know the exact cause and treatment, you should visit a dentist. This way, you can know your options on how to whiten your teeth. Note that you should not brush harder to get rid of that yellow hue. This can further erode your enamel and show more of the yellow dentin underneath.
