What are Oral Injuries?
There may be times when a piece of twig or a rock can become lodged across the roof of your dog’s mouth, called the hard palate. This type of situation will cause distress to your dog and they may become panicked, clawing at their mouth or coughing. Your primary veterinarian will most likely be able to remove the stick or rock without having to perform surgery; which will often involve sedation.
Veterinary dentistry is becoming an important part of a dog’s routine care. You should maintain a regular schedule of dental cleanings and examinations so your dog can be quickly treated for any oral injuries that are preventing them from being comfortable. Some veterinarians are equipped to handle specialty cases involving oral injuries, but in many cases, your veterinarian may need to refer you to a dental specialist.
Just like humans, oral hygiene and care is very important to dogs. Oral injuries can occur to the soft tissues of the tongue, cheeks, lips or tonsils from foreign objects that dogs like to find and chew. Lacerations are the biggest problem in a dog’s mouth since the soft tissue is sensitive and susceptible to cuts, abrasions and infections. Tumors of the soft tissue of the mouth along with other oral injuries can cause your dog to have difficulty eating.

Symptoms of Oral Injuries in Dogs
When your dog is suffering from an oral injury, sometimes you do not realize they are in pain until you begin to notice weight loss or a refusal to eat or drink. In some instances, the pain is so severe that you have an emergency situation; you will need to seek veterinary attention immediately. Symptoms of oral injuries to watch for include:
  • Swelling of the lips, tongue or cheeks
  • Lump on the lips, tongue or cheek
  • Open laceration in the mouth
  • Foul smell in the mouth
  • Pus or blood in the mouth
  • Refusal to eat or drink
  • Weight loss
  • Clawing at the mouth
  • Crying when chewing
  • Sensitive to a physical examination of the mouth
  • Excessive drooling
Causes of Oral Injuries in Dogs
Oral injuries in dogs can occur from a number of different sources. Dogs are forever finding foreign objects to chew on and sometimes those objects cause lacerations, punctures or even abscesses in your dog’s mouth. Oral tumors are also a concern when any type of mass is found your dog’s mouth. Sticks can become lodged in the roof of your dog’s mouth, causing irritation and panic in your dog. Lacerations can occur from bones, wood or rocks that your dog finds,. Lacerations can easily become infected if not treated quickly. Puncture wounds in your dog’s mouth from foreign objects can cause abscesses and infections that can become life-threatening. 
Oral care for your dog is essential for maintaining a healthy, long life. It is essential that you schedule regular dental examinations and cleanings for your dog. By having regular examinations, any oral injuries can hopefully be found and resolved before they become serious and potentially life-threatening.
Diagnosis of Oral Injuries in Dogs
Your veterinarian will begin by taking your dog’s full medical history and a list of the symptoms that you have observed. A physical examination of your dog’s neck, head and mouth will be done by your veterinarian. In order to perform a thorough examination, your veterinarian may need to sedate your dog or use general anesthesia. The oral cavity will be checked for any signs of injury such as bruising, lacerations, remnants of splinters or abscess.  
X-rays and ultrasounds may be ordered to look for any signs that a foreign object has caused your dog distress in their mouth. Endoscopy can also be used to determine if a foreign object has been pushed down into the esophagus. 
Your veterinarian may opt to refer you to a veterinarian who has specialized in canine dentistry if the oral injury is too severe for general veterinary medicine to deal with. Severe lacerations, tumors or abscesses may require a specialist to properly treat.
Treatment of Oral Injuries in Dogs
Oral surgeries in dogs are on the rise as more and more veterinarians are specializing in canine dentistry. If your dog is suffering from a laceration in their mouth, they will need to be put under general anesthesia. While they are under general anesthesia, the laceration will be fully assessed, cleaned and sutured. A course of antibiotics will be prescribed to prevent infection.
Abscesses found in the mouth will also need to be initially treated under general anesthesia. Your veterinarian will fully assess the abscess and will most likely need to lance it so the infection can drain. A drain tube may need to be inserted to ensure that the abscess does not close prematurely. Antibiotics will be prescribed to remove the infection and prevent further complications.
Oral tumors will require a biopsy to determine if the growth is cancerous or benign. The biopsy will be done under local sedation or general anesthetic. A portion of the tumor is removed and sent to a lab for biopsy. Depending on the results of the biopsy, the tumor will need to be surgically removed and then the area will need to be monitored. Antibiotics will be prescribed following surgery. If your dog is diagnosed with cancer, then your veterinarian will discuss treatment options and prognosis at that time.

In all of the above scenarios, pain relief will also be required to ensure your dog is comfortable.

Recovery of Oral Injuries in Dogs
Most dogs will have a good prognosis following being diagnosed with oral injuries. Your veterinarian will be able to give you an accurate recovery timeline for your dog’s oral injuries.

Dogs that have been diagnosed with cancer may have a more guarded prognosis depending on the type of cancer and to what stage it has progressed.

Cut On Tongue
Dog has a large cut on her tongue. Does she need stitches?

Thank you for your question. Pets in the tongue tend to heal quite quickly, and don't often need sutures. If the wound is not bleeding, it may heal on its own, and what you can do is Monitor it for any signs of infection or ongoing bleeding. She may need to be fed soft food for a couple of weeks while it heals, but these wounds are often fine. If it does start to show signs of infection or she does not want to eat, then having her seen by a veterinarian would be best. I hope that all goes well for her.

Thank you for your question. Unfortunately, I"m not able to see what you are looking at in the picture that you sent. If you are concerned that there is something on her lip that is bothering her, and it isn't getting better, it would be a good idea to have her seen by your veterinarian, as they can examine her and see the issue that you are concerned with. I hope that all goes well for her!

My pet has the following symptoms:
Gym Laceration
My 3 year old boxer got a gum laceration yesterday. We think he tried jumping along the brick wall and may have hit his gym. This caused a chunk of gum to hang from his mouth with a small tooth. His breath has gotten smelly. We have been feeding him soft foods. His vet suggested NOT to get OTC pain reliever from Petsmart. He has an appointment on Monday. Any suggestions for cleaning the area?

Thank you for your question. I think that would be painful to clean, and I would leave it alone until you can see your veterinarian.

My pet has the following symptoms:
Tongue Bleeding
My dog chewed a bone yesterday and then became very lethargic. Does not want to be around people right now. He is still eating and drinking at the momemt, although drinking seems a little painful. He is constantly licking his fur, drooling(sometimes a little foamy), and some blood that stops very quickly. I cannot see anything in his mouth. I am wondering if I should take him to the vet during this pandemic or try and treat him at home

Hello- Thank you for reaching out. I do think it would be a good idea to take him to the veterinarian. There could be a piece of bone lodged in his mouth or a laceration that’s difficult to see and your vet will be able to examine him, give him some sedation medication and then do a thorough oral exam. Many vets are doing curbside service during the pandemic so if you’d prefer to drop off versus being in the hospital most clinics are offering that as an option. I hope he feels better soon.

My pet has the following symptoms:
Coughing
He ate a little piece of a chip and starting coughing then threw it up but started eating a lot of grass and now keeps licking his lips

Hello, So sorry that your dog is having issues. The chip could have injured his throat. It would be best to feed him soft foods for a day or two to allow it to heal. If he continues to vomit, it would be best to see your vet.

My pet has the following symptoms:
Bruise
Bruise Tongue
Patch Of Skin Missing
Frost Bite
We are going through the polar vortex right now and we're in the Midwest. 2 nights ago he went out to play for 20 min and came back with patches of skin missing from tip of his tongue, with a little bleeding around the patches. And last night we found a bruise under his tongue. I'm thinking it's from the cold, but is there anything I can do about it? Or is it actually a serious condition? He's peeeerfctly fine! We coconut oil his paws nose n coat especially with the cold. He even licks his oil container and eats a little on it's own... I just don't know what to do about the tongue. Thanks
