Keep the water clean with frequent water changes to help prevent a secondary infection and to encourage healing. You removed the possible cause (plastic plant)...if you have a filter watch that too if it has a strong current and baffle as needed to prevent more damage.
IME-Depending on the amount of damage, but generally healing and re-growth can take 3 days to 3 weeks. Sometimes, again, depending on amount and location of damage the re-growth can look white in color and may not regain the normal color/look as it once did before damage.
