You may often find that no matter how much you brush your teeth or whichever teeth whitener you might use, your teeth still appear stained and your smile still appears dull. There are certain foods, such as coffee, alcohol like red wine, soya sauce etc. which can be considered obvious culprits. However, it is not only the foods that cause staining, several other factors contribute to this as well. Following is a list of 5 things which can stain your teeth sooner than you think.

1. High intake of tea
Research has suggested that tea, be it brewed tea, green tea or iced tea, causes a high level of staining in your teeth; often in levels much higher than coffee. This is because tea contains a high level of tannins and also high amounts of acid, which aid the staining process, and eventually lead to much yellower teeth and long-lasting stains.

2. Drinking high amounts of lemonade
Lemonade is rich in sugars and acids, which effectively lead to wearing down of the enamel and exposing the next layer called the dentin, which itself is yellow in color. This makes the teeth appear yellowish. In cases where the enamel coating on your teeth is thin, the acid erosion takes place quicker; often leading to stained teeth. This condition may often become permanent or semi-permanent, with modes of reversal becoming increasingly difficult.

3. Extended periods of medication-intake
Injuries or illnesses, which lead to taking medications for sustained periods, can negatively affect the flow of blood to the teeth. This may lead to discoloration and staining. Certain medications, such as cough syrups which are rich in sugars can, also result in yellowing of teeth.

4. Swimming for long durations
Swimming for prolonged periods [usually around 6 hours a week in chemically-treated pools, can also lead to the browning of your teeth. This is because, often when you open your mouth and let water in, you allow certain chemicals to enter your mouth which can have adverse reaction on the tooth enamel. This ultimately leads to teeth corrosion and eventual staining.

5. Having excessive sugary drinks
Certain drinks which contain large amounts of synthetic food coloring increase sugar levels and aid the growth of bacteria in your mouth, thus causing tooth decay and discoloration of teeth.
