In response to the 2015 refugee crisis Davies said that most of the people attempting to enter the UK via Calais were not refugees fleeing war, but were economic migrants "mostly young men, mostly with mobile phones, chancing their luck". Davies attracted media attention in October 2016 with a tweet suggesting refugees to the UK should have dental checks to determine their age. His view was criticised by the British Dental Association which issued a statement describing the test as "inaccurate, inappropriate and unethical". The suggestion was also criticised by the British Association of Social Workers, and the test was also ruled out by the Home Office. In October 2016, Davies said that a child migrant arriving in the UK from Calais had "lines around his eyes and looks older than I am." Davies appeared on ITV's "Good Morning Britain" on 19 October to defend dental checks, but became engaged in a heated exchange with Piers Morgan, who accused Davies of demonising refugee children, a charge which Davies denied. Later that year, Home Office figures revealed that more than two-thirds of refugees arriving in the UK who had their age assessed were over 18.
