Hello, I recommend that you see your dentist, take an X-ray and have your front teeth evaluated for an abscess. Trauma from intubation can cause dental problems. You already are aware of tissue trauma from the bruising. There could be a fracture. Signs for greater concern include pain, loosening of your teeth, bubble on gum below teeth, darkening teeth, cracking and inability to bite. You can rinse with warm salt water. Avoid irritants and direct pressure. Maintain good daily hygiene. Taking Antiinflammitory medication such as Tylenol or Advil may help. If tissue continues to heal and return to normal, you may have just had soft tissue trauma and only need time to heal. Thank you for your inquiry.
