It seems like one of my teeth is wobbly and feeling loose.

While chewing dried squid, one of my molars suddenly felt loose, and now I feel discomfort every time I eat rice. At first, I thought it would get better with time, but when I eat hard foods, I don't feel pain in the molar, but I do feel a sort of lifting or floating sensation. It also feels somewhat loosened, and I am very worried. Usually, it gets better within a week, but this time, even after several months, there has been no change, and I am concerned.
