What are the sinus problems that causes teeth grinding?

Usually unrelated: The roots of some of the upper back teeth may be close to the maxillary sinus and therefore sinus problems may produce what seems like a toothache. However, tooth grinding or bruxism is more related to stress and anxiety, or in some cases, bite problems. Discuss sinus problems with your physician and grinding problems with your dentist. They are both independent and there are remedies for both.

Pseudo-Sinusitis: also called fake" sinusitis caused by tooth grinding. The force caused by the jaw muscles when clenching at night can stimulate the ostium causing irritation of the membrane and triggering all the sinusitis symptoms. Currently, no therapy has been proven effective in treating sleep bruxism. Maybe night guard to protect your teeth.
