Teeth stainer: Acidic beverages
Sorry coffee addicts, but your caffeine habit has a detrimental effect on your teeth. Acidic beverages such as coffee, tea, and soda alter the pH balance of your mouth and damage the surface of the enamel. Soda is especially dangerous, as its exceedingly high sugar content and carbonation can actually erode enamel to the point of forming holes in teeth.
If these beverages are daily indulgences for you, drink lots of water to wash away those stains or chew crunchy vegetables to promote salivary flow, which also helps to remove stains. Also, load up on drinking straws, which help the staining liquid bypass your chompers.
