There are different types of tooth stains that could potentially be removed through the use of teeth whitening techniques. However, not all stains can be removed through the use of teeth whitening. Understanding the type of stains that you have will determine the right treatment to address your condition, and help you achieve a brand new, brighter smile.
Teeth are naturally porous. Each tooth is made of hollow tube-like structures referred to as dentin tubules. When the enamel layer of teeth picks up stains through the tubules, the teeth lose the natural shine and colour. It may be caused due to acidic food or beverages like red wine, carbonated drinks, tea, or coffee. In some cases, oral health problems also lead to tooth discolouration and effective teeth whitening procedures can remove the stains from teeth.
