GRANDMOTHER, YOUR TEETH ARE SO....WHITE!
All the better to smile at you, my dear!
Teeth whitening has become so popular that is has become a regular part of a patient's treatment plan (after the needed dental work has been done). Due to lifestyle and eating habits, our teeth can get stained, dull or discolored. Don't worry, we don't judge!
The darker tissue of your teeth, the dentin, can become exposed as the outer layer of enamel is worn away by the effects of aging or things like caffeine and tobacco. And over time, teeth can actually become more absorbant and vulnerable to staining from food and other agents.
Some "whitening toothpastes" can be somewhat effective at removing stains ...
