We understand the importance of immediate dental care and are ready to address any dental emergency, big or small, to restore your health and peace of mind. Severe Tooth Pain: If you have intense, persistent tooth pain that doesn’t go away with over-the-counter pain medication, it may be a sign of an infection or abscess. For Lost Fillings or Crowns: If a filling or crown has come loose, place dental wax or temporary dental cement over the exposed area to protect the tooth.
