Pub landlords in Nottinghamshire have been warned they could be forced to use plastic glasses.
Officers in Retford and Worksop said despite glassing incidents being rare, a recent case had emphasized the damage they could do.
Now pubs not using plastics on busy nights would face a fast track review of licensing conditions which force their use full time, police said.
Pubs said they had to consider cost and branding regulations.
Officers said the move was timed to coincide with the festive period but is also just weeks after a 32-year-old man was sentenced to 15 months in prison after admitting glassing another man in a Retford pub.
The attack, which took place in March 2010, left the victim, aged in his 40s, requiring 25 stitches to a head wound.
Sgt Andy Wilson, of Nottinghamshire Police, said the force was determined to limit such incidents.
"However, we also need the co-operation of the licensing trade. We are asking for all pubs in Worksop and Retford town centres to serve drinks in polycarbonate glasses on high days and holidays.
"If they don't comply we have the power to call an expedited review of the licensing conditions. That review could result in the licensee being required to serve drinks in polycarbonate glassware at all times."
