Biting Pain: Sounds like your filling as been comfortable until recently. Sudden biting pain is usually related to a cracked tooth. The happens a lot with large fillings and someone with a strong bite. See your dentist. At the least you probably need a crown, if the crack extends into the nerve you may need a root canal. If the tooth is actually split, you could loose the tooth. See your dentist soon.
