It sounds to me like you are anxious about your jaw and possible ear/throat symptoms. I can assure you that bruxism and TMJ issues, while frustrating, will not be permanently affected by your delay in treatment. Surgery is a rarely used option, and only after a series of other treatments, including self-care, have failed.
In these strange and stressful time, it is easy to say this, but do whatever you can to reduce your stress level too – deep breathing, stretching, physical exercise, soothing music, meditation. And avoid activities that increase tension in your body – including competitive video gaming, which causes tension in the neck shoulders & jaw.
Let us know how things go!
