Pain all over the mouth is due to night teeth grinding or it can be due to multiple caries. I suggest you to visit the dentist to get the correct diagnosis. If the pain is radiating to the temple region than bruxism (nigth grinding) is the cause but if it is shooting and localized or radiating to eye region, than it can be due to caries.For more info on tooth pain visit the link...http://www.identalhub.com/articlecategory-dental-pain-42.aspx
