Limited opening : This can be a sign of TMJ dysfunction or bruxism. If there is damage to the disc that the jaw rests on or if the jaw gets stuck on the disc or there is swelling in the disc it can feel like the teeth don't fit together right or you can experience limited opening . Have it checked by your dentist.

Brush, rinse, floss: Brush and keep them clean, floss them gently and try rinsing with warm salt water in that area specifically. Rinse for a minute or so or as long as you can. This should help it go away. If the swelling is not going away you need to see your dentist to have it checked out. Good luck.

Hydroquinone cream: Try hydroquinone cream. Rub in a small amount 2 times each day. You can find a 2% hydroquinone cream over the counter in most pharmacies. Natural liquorice extract is another treatment that works but is usually not as effective.
