The best and fastest way to clean up tooth stains is to go to the hospital for a full mouth cleaning and polishing or sandblasting. Do not listen to little recipes such as using baking soda to rub our teeth, although it can rub off our stains, it will leave scratches on the surface of our teeth, which will cause great damage to our teeth and later accumulate more stains, so it is important to take a scientific approach to clean the stains. Tooth stains are formed mainly because we like to drink colored beverages or have the habit of smoking. Patients are advised to at least rinse their mouths after smoking or drinking colored beverages to reduce the stimulation of such stains on our mouths, and it is best not to smoke if possible.
