Great question, let me help you.
These symptoms are typically caused by medications or biologic changes in your body
If you have been on antibiotics, they could have caused this, and these symptoms will go away after a week after taking the medicine
If the symptoms persist longer than this, then it is likely a hormonal change in your body
Many women your age go through hormonal changes that can cause these kind of symptoms, but realize they are short-lived, and not permanent. They will go back to normal after no longer than a few months.
It is nothing to worry about
And nothing you have to see your dentist for.
