Complicated Dental (Tooth) Fractures in Dogs

Overview of Complicated Tooth Fractures in DogsDental fractures (broken teeth) are a common problem in veterinary medicine. Both dogs and cats experience these fractures at a rate of 10% to 20% of all pets. Dogs, however, not only seem likelier to sustain these types of injuries, they’re also susceptible to a wider variety of dental fractures than their feline counterparts.Fractures are often roughly classified as either complicated or uncomplicated. Due to their typical differences in cause, diagnosis and treatment, there is a separate article for uncomplicated dental fractures in dogs.Trauma is the typical cause of complicated dental fractures. The source of trauma includes the following:- Blunt trauma to the face (as when dogs are hit by hard objects during vehicular trauma, athletic events, or while engaged in police or military work)

What to Watch For

The clinical signs of dental fractures are not always as obvious as dog owners might suppose. Indeed, most dogs don’t display any outward signs of pain, even after sustaining complicated dental fractures. Most manage to avoid detection either by chewing with the other side of their mouths or by swallowing their food whole.

Some dogs will, however, display subtle signs that something may be amiss in their mouths. The following may serve as circumstantial evidence of a complicated dental fracture:

Dogs and cats whose complicated dental fractures have led to a tooth root abscess may notice swelling on the side of the face and sometimes even open, oozing sores on the face (most commonly under the eye).

Diagnosis of Complicated Tooth Fractures in Dogs

Definitive diagnosis of complicated fractures, particularly root fractures, requires dental X-rays (always performed under anesthesia).

Many veterinarians in general practice are now equipped with digital dental X-ray capability to quickly assess the problem. Without taking X-rays, it may be impossible to fully assess the tooth’s degree of compromise, classify the fracture, and/or achieve the correct treatment.

Treatment of Complicated Tooth Fractures in Dogs

Treatment of dental fractures typically depends on their type and severity as well as the time elapsed between the fractures and their detection. As for X-rays, anesthesia is always required for these procedures.

When the pulp is exposed, as happens with most complicated fractures, veterinarians usually have only two options: extract the tooth or perform a root canal. Root canals aim to remove the affected pulp and replace it with a special material before applying a new crown that will allow the tooth to function as it did before.

Extraction, however, is similarly effective in relieving pain along with the source of infection. While extracting the tooth results in the permanent loss of a normally functioning tooth, it’s typically the most affordable option.

In some cases, as when the fracture extends into the root, extraction is the only option. But not all root fractures automatically require extraction. If it doesn’t result in a loose tooth or involve the crown, this kind of fracture may well heal on its own. However, these teeth have to be X-rayed often (every six months at least) to be sure they’re healing properly.

Veterinary Cost

The cost of dental fractures varies depending on the species, the kind of fracture and the treatment elected.

Complicated fractures that require extraction may run an owner $500 to $1,000 for a large tooth, if it’s extracted by a general practitioner (significantly more should a board-certified dentist be enlisted). However, this procedure may cost significantly less for cats.

Root canals in dogs and cats cost roughly the same as they do for humans. $1,500 to $3,000 or more is common. The canine tooth in a large dog, in particular, can be very expensive. Depending on the geographic location, a root canal performed on this tooth can cost up to $6,000.
