I Am Planning to Get Invisalign Braces from India During my Holiday and I Am Living in UK?

Although it will likely be cheaper to go this route in the short term, I would highly suggest against doing it.  Especially if someone has told you that you may need 4 teeth removed.  That would indicate you have lots of crowding.  Invisalign will not be a good choice for such significant crowding. 

Besides, your orthodontic treatment is an ongoing process.  It cannot be done with just one visit to a dentist/orthodontist overseas.  

You will be wasting your time and money by doing it this way, no matter what the dentist in India tells you.  Over the long-run, you will have to pay again back in the UK to have it done properly.

Also, we use metal braces for severely crowded teeth all the time.  The level of crowding is not a determining factor for whether we can or cannot use metal braces.  Unfortunately, that argument that was given does not hold water.  

Please don't do it!

Yes Ofcourse you can get Invisalign from India. Infact I have many patients who start their Invisalign treatment with me and I follow up with them either through their visits to India often or through FaceTime. We need to see our patients with Invisalign at least once in six months to see the progress in case they are not in town. I am one of the Certified Invisalign Specialists in Delhi, India and have many patients coming to me from the US and the UK for Invisalign. 
At our practice in both Delhi and Gurgaon, we charge $4000 which includes of all your visits, impressions, X-rays and any additional aligners that maybe required.
Hope this helps.
Warm Regards.

we charge US$3050 for invisalign complex cases. only thing u have to take into consideration is u have to stay for 45 days in india.
