That depends on the damages. If the damages was there when you moved in, you are not obliged to pay for a replacement of the whole floor.
Probably you have paid too much in rent like 90 % of all tenants of privatly owned appartments. If you complain to the local Rent commission (“Huslejenævn”), you have a chance of getting some of the money back.
Become a member of a tenants organisation (“Lejerforening”), and get help.
