Teeth discolouration is a common problem, faced by people all over the world. Black tea, black coffee, smoking, red wine, are the most common cause of teeth discolouration. Apart from this, sodas, and aerated cold drinks can harm the enamel and make it more prone to discolouration. Teeth whitening products like toothpastes or home remedies can also do more harm than good . Such products usually work by removing the layer of your enamel which can lead to tooth sensitivity.  Therefore,  it is recommended that if you want a million dollar bright white smile, it should be done under the supervision of a Dentist  at the Happy teeth corio dental clinic.
