Yes, if the dental work done is non-routine. For example can’t claim for filing’s or extraction of teeth etc.
Non-routine dental treatment obtained outside the State may be allowed provided the dentist is a qualified practitioner (i.e. entitled under the laws of the country in which the care is provided to practice dentistry there).
