Discolouration of Teeth
You can run, but you can't hide. The same can be said about disturbingly yellow teeth. Your teeth are covered with a smooth enamel that is naturally white. When that wears out it becomes translucent and reveals the lower layer called 'dentil' that is yellow in colour. The enamel wears out over time but certain habits, dietary and otherwise can accelerate it. (Food items that may damage your teeth)
Too much tea or coffee - Drinking too much tea or coffee stains the teeth. Not only do they erode the enamel but they also make the teeth stickier which causes food particles to latch on.
Sugary drinks - This one's a double whammy. It's a mix of acidity and sugar, both of which are bad for the teeth. If you still want a glass or two once in a while then we suggest you drink quickly instead of sipping on it over a long period of time and rinse your mouth after.
Smoking - This is probably the worst cause for tooth decay and discolouration. It damages the teeth beyond repair. Not only does it make them yellow, in some cases it also leaves behind permanent grey marks that can't be removed.
Brushing right after eating - This might seems harmless and even good but dentists suggest you drop this habit. The acid and sugar produced when we eat weakens the enamel temporarily and brushing it at the time weakens it further. Ideally, wait for half an hour or more or brush before eating and rinse your mouth after the meal. more
Good information though the last comment on brushing right after eating is not clear. Did you write that we should brush half an hour before eating? Similarly, what is sugary drinks? I drink honey and lemon water every morning. Is it helpful or harmful for my teeth. Yes, one change I'll attempt i.e. reduce the intake of tea. Regards and thanks for informative dental care. more
