Causes Of Stained Teeth
Our teeth can be stained by many things, the main culprits are however, smoking and drinking dark drinks such as red wine along with coffee and tea.
Acidic drinks such as juices and sodas can also cause staining.
How Can I Stop These Drinks Staining My Teeth
The easiest thing to do is to stop drinking them, but this is easier said than done. Drinking through a straw would help protect the front teeth , but if this is not possible then you should always try to rinse your mouth with water immediately after drinking.
Other Reasons For Teeth Staining
Some antibiotics are well known to cause teeth staining, of these, the worse ones are minocyline and tetracycline that tend to leave a bluish grey stain on 
the teeth that is quite hard to remove, especially if taken for extended periods.
Other medication including some antihistamines can cause staining. If you are concerned about your medication staining your teeth, speak to your dental surgeon or doctor who may be able suggest a less harmful alternative.
Getting older has a defined effect on our teeth, with age, the enamel becomes thinner and this exposes the yellow under layer called Dentin. Genetics play a big part in just how white or strong your teeth are.
Dark foods and fruits can also cause varying degrees of teeth staining, two such examples are cranberries and soy sauce.
A rule to remember is:
If the food or drink is likely to stain your clothes, it will also stain your teeth
Always rinse your mouth after eating any dark coloured foods
Staining can also be caused by injury to the teeth or after invasive dental procedures such as root canal work
How To Keep Staining To A Minimum
Keeping to a good dental care routine will help, brushing at least twice a day, flossing and making sure that you see a dental surgeon at least twice a year will help maintain your teeth in top condition.
How To Reduce Stains On Teeth
If regular brushing will not remove the stains, then perhaps you should consider teeth whitening, now a common procedure it usually involves the bleaching of the teeth to remove al the stains, leaving you with nice white teeth
Most Dental surgeries offer this treatment, but costs can be prohibitive, at around $250 CAD upwards, many people just cannot afford the costs involved and start looking for cheaper home based treatments that can whiten their teeth.
Home Treatments
The development of good home teeth whitening kits has made this choice far easier.
A good kit will provide the same level of cleaning and whitening that you would get at the dental surgery, but with a massive difference in price.
