Greetings,
There are a lot of reasons that can loosen a tooth.
In order to find the exact cause of this problem, a clinical examination is required.
For black fungus - a biopsy test will be recommended.
If you need any further help or advice then you can consult me on practo.
All your queries will be solved.
