The colour of natural teeth can vary widely based on many factors. Additionally, time, wear, and staining can change the colour of the teeth over time.
The most effective way to prevent staining is by avoiding common substances that stain the teeth, including coffee, tea, red wine, and berries. If you can’t avoid these, brush your teeth directly after consuming them whenever possible or rinse with water. Smoking and tobacco use can also stain the teeth, as well as certain types of medications, and trauma to the teeth.
