When to See a Vet

Seek immediate emergency care

  • Heavy oral bleeding that cannot be stopped
  • Bleeding accompanied by fainting or significant difficulty breathing
  • Large open wound in the mouth with exposed bone

Schedule a clinic visit soon (within 24–72 hours)

  • Persistent refusal to eat or significant decrease in food intake
  • Obvious difficulty chewing or spitting out food while eating
  • Excessive drooling or persistent blood around the mouth

01What Symptoms Indicate a Problem?

Alveolar bone trauma commonly presents as oral bleeding and pain, affecting eating, drooling, and behaviour. Early assessment is important to prevent complications.

  • Oral or gum bleeding — may occur suddenly or recur
  • Reluctance to eat, difficulty chewing, or noticeably slower eating
  • Excessive drooling or food residue and blood around the mouth
  • Avoidance when the mouth is touched, resistance to opening, or vocalisation of pain
  • Swollen gums, bad breath, or a sense that a tooth feels loose or unstable

Seek emergency care immediately if you notice the following symptoms:

  • ⚠️ Heavy bleeding that cannot be controlled, persistent oozing, or pulsing/spurting blood
  • ⚠️ Bleeding accompanied by obvious weakness, collapse, or lethargy
  • ⚠️ Difficulty breathing, markedly rapid breathing, or cyanosis

02How Can You Assess the Situation at Home? Key Observations and Emergency Criteria

Observing and recording specific details and timing at home helps the vet quickly assess the extent of injury and prioritise treatment.

  • Record the time of the injury and when bleeding was first noticed
  • Use a phone to photograph and video the inside and outside of the mouth
  • Note any changes in appetite, water intake, and urination/defecation
  • Observe whether touching the mouth causes avoidance or a pain response
  • Weigh your pet and note any significant weight change in a short period
  • If there is heavy bleeding, arrange emergency veterinary care immediately

03How Will the Vet Diagnose? Common Examination Steps

At the clinic, the vet will use oral examination and imaging to assess the extent of damage, and confirm overall condition and anaesthetic risk with blood tests.

Full oral physical examination to assess the gums, tooth stability, and soft tissue injuries

Dental and skull X-rays to confirm damage to the alveolar bone and tooth roots

CT (computed tomography) for detailed assessment of complex or deep fractures

Blood and biochemistry tests to evaluate overall condition and anaesthetic risk

Urinalysis and pre-anaesthetic assessment; referral to a dental or specialist hospital if needed

04How Is It Treated and Managed After Diagnosis? Medications, Diet Adjustments, and Care Guide

Treatment ranges from haemostasis and infection control to surgical repair depending on severity; regular follow-up visits and imaging are needed whether surgery or conservative management is chosen.

  • Initial focus is on stopping bleeding and preventing infection, commonly with antibiotics and local haemostatic treatment
  • Severe alveolar bone or root damage may require surgical stabilisation or gingival repair
  • After surgery or conservative treatment, regular follow-up visits and imaging to monitor healing are scheduled
  • Transition to soft food and restrict chewing — avoid hard objects or toys that could cause further injury
  • Home care includes oral hygiene and medications or dressings as directed by the vet
  • Referral to a dental specialist or specialist hospital is recommended to assess long-term tooth function

05What Should You Prepare Before the Vet Visit? Key Information to Help Your Vet Quickly Identify the Cause

1
Record when symptoms appeared, frequency of bleeding, and any changes over time
2
List recent food intake, changes in appetite, and water consumption
3
Note any changes in elimination patterns and activity level
4
Prepare a list of current medications or supplements for the vet's reference
5
Bring photos and videos of the mouth, and use a secure carrier to minimise stress
6
If you have past X-rays or examination reports, bring them along for comparison
