Translation of orthodontist in German

I hope my explanation was also clear that would say that for english verbs a to needs to be put from the selection list. Like: inhale would be 'to inhale' == 'inhalar'. The 'to' is taken from a selection list.
I think it's a good idea to fly to Antigua to a language school. I feel more confident with the grammar in Spanish. Perhaps it would be better if the school would arrange the accommodation.
I have problems with adjectives, endings and articles. The grammar is so difficult. I am very happy to learn Spanish with you. What went wrong with the lessons? Thanks and best regards.
