While most people are trying to avoid unhealthy foods such as fatty dairy, sweetened desserts and deep-fried food, many of us have a hard time letting go of our love for a cup of coffee or tea. Coffee and tea can seem innocent when compared to a bag full of spicy and oily chips or sweet confections. However, tea and coffee can have a lot of sugar. It is easy to see the link between tea and tooth erosion. Tooth decay is caused by sugar in tea and coffee.
Here are the main effects of coffee on your teeth
•    Nature also makes coffee acidic. Acidic by nature, coffee and tea contain sugars that react with the bacteria in your mouth to create acids. These acids can be very damaging to your teeth's protective coatings. Your teeth' inner layer, which is composed of open nerve endings, will be exposed.
•    Coffee contains caffeine, which can dry out your saliva. The growth of bacteria is normally suppressed by saliva. This means bacteria can multiply more quickly and cause bad breath. Sugar-free gum can be used to stimulate saliva and fight bacteria, which will help freshen your breath.
