Well if you need to replace/ repair the damages then you can claim against their security deposit. You should liaise with them first if you haven't already done so. Inform them of the damages and your intention to claim against their deposit so they are not surprised to receive an e-mail from Airbnb re the claims.
You shouldn’t let fears of a bad review determine your actions if these actions are fair. If you are OK with absorbing the financial burden of the damages because you have factored stuff like this into your price, then that is one thing and you may decide to let it be. However if you are not happy to bear the full responsibility, then you should inform them of the damages they have left behind, the cost implications to you and their responsibility financially in this matter.
This might sound harsh bit there is no guarantee that they will leave you a great review even if you don't mention this. And if they do leave you a less favourable review as a result of a claim, they can't tell lies otherwise Airbnb can remove the review; also you can leave a public response to their review. Most importantly, potential guest do have the intelligence to read reviews and decide for themselves if it warrants concern or not. As a Host, I have made two claims against Security deposits, one did leave me a 5* review despite the claim and the other missed the 14 day review window whilst traveling but e-mailed me to say she had a great time, so not every guest runs away from their responsibility or retaliates when their errors are pointed out to them - just my thoughts….
All the best,
