I did it in Nepal. Contact Sirish , who knows more.

Some tips.

1) Do not have to tell you, brush gently 2-3 times a day.

2) Rinse mouth every time after eating any thing.

3) Flush atleast once a day.

4) Instead of mouth wash , use 3-4 dorp of Peroxide in 6 oz water , rinse every night, it will take care of gum disease( a liittle bit).

5) Use sensodine to protect tooth enamel.

Give them a call, some times they will give you an option to pay in installment.
