Matt Wrack, the general secretary of the NASUWT teaching union, said it was "horrifying to hear that multiple teachers in the South East have reported experiencing suffering serious injuries".
"Sadly this is borne out by our own data where teachers report being bitten, kicked and punched while teaching," he added.
"Pens, scissors and even tables have been used as weapons."
Mr Wrack said the problem was worse in secondary schools, but they were also seeing an increase in this behaviour from primary pupils.
"It's frankly outrageous that teachers have started to see this as just part of the job," he said.
The government has announced a review into behaviour in schools.
"We need counsellors in every school and an increase in alternative provision for pupils with higher needs," added Mr Wrack.
