Does the term “Practice Limited to Orthodontics” or “Orthodontic Practice” or “Orthodontic Centre” mean that the dentist who works there is necessarily an orthodontist ?

Definitely not , this simply means that the dentist no longer does general dental procedures like extractions or fillings or dentures etc it certainly does not mean that they are an orthodontist , or indeed that they have any recognised postgraduate training of any sort in orthodontics . This simply means that they have chosen to no longer perform procedures like extractions , fillings, dentures etc.
