Why do my upper front teeth make a clicking sound on being pushed by my tongue?

Hello doctor,

Two months ago, I felt my upper front teeth clicking on, pushing my tongue against them. It generally happens when I eat, but not all the time. After a few days, this feeling resolved, and the symptoms reappeared two weeks ago. My last dental cleaning was three months ago, I was informed that my gums were in good health, other than a couple of four-millimeter pockets. Last week, I consulted my dentist about the symptoms, but he could not find any issues or the need to take an X-ray to investigate further. I do not have a habit of clenching or grinding, the doctor said it was possible I slept with my tongue pushed against my teeth. I have been experiencing anxiety for the past few months, and I am hyper-aware of this sensation. I feel tempted to check whether my tooth has loosened. I am regularly taking multivitamins. What is the cause of my concern? Will the symptoms resolve by itself? Please help.

Thank you.
