i have noticed that over the past few months my husbands teeth have started staining. he drinks a lot of tea, no smoking though...
any home remedies to get rid of the stains?
or any permanent solution? we are willing to go in for medical tourism to India or Thailand...

Hi,
Stains on the teeth could have been caused by tea. Also as a person ages the enamel layer wears off and so the teeth gets stained faster. Medical Tourism just for stain removal is useless – If you wish to visit any of the countries on vacation U are most welcome as a bonus U can get both of your teeth cleaned and whitened.
Remedy for staining of teeth is to clean your mouth immediately after taking any food or beverage. Brush your teeth with a mixture of baking soda and table salt once a week.

Hi, Page Me is right about avoiding medical tourism just for this. The travel would far outstrip any gains you may make on this procedure. You may not even need a dentist, you can try any OTC teeth whiteners from your locat pharmacist.
