Hi Kiwiinqld
Welcome to the forum and congrats for being the first poster ever!
I'm not quite sure how this is all going to run yet... I suppose a good start would be to answer your question.
Could someone tell me how safe it is to travel overseas for dental work?
This is a very broad question and my first instinct is to say, it depends on where you travel and the dentist you choose.
From my experience a good check list would be:
How experienced is your dentist ?
How long has the dental clinic been in business?
Ask to see gennuine examples of their work
Will they provide a trial fitting of your crowns etc before you leave for home?
Ask to see the qualifications of your dentist.
Ask them to send you their sterilisation methods.
Do they use disposable shringes?
Where do they source their materials, Germany,USA or local ?
Do a search for negative feedback.
Traveling overseas for dental work or any purpose will always carry some risk. but I think the risks can be greatly reduced with careful planning and research.
I did my initial trip alone but given the choice again I would take someone with me. New places seem a lot more fun to explore when you have company.
