When a "Good" Chew Goes Bad: Preventing Tooth Fractures in Dogs

Chewing is a normal, healthy behavior for dogs. It provides enrichment, reduces stress, and can even support oral health—when appropriate materials are used.

However, one of the most common reasons dogs present to a veterinary dentist is due to tooth fractures caused by chewing on overly hard objects.

What’s often intended as a beneficial habit can quickly become a painful dental injury.

Why Do Teeth Fracture?

Teeth are strong—but not indestructible.

When a dog chews on an object that is harder than the tooth itself, the force has to go somewhere. Unfortunately, that force is often absorbed by the tooth, resulting in a fracture.

In many cases, these are slab fractures of the upper fourth premolar—one of the most important chewing teeth.

Common Causes of Dental Fractures

We frequently see fractures associated with:

• Antlers

• Nylon or “indestructible” bones

• Hard plastic toys

• Natural bones and hooves

• Ice cubes

While these products are widely available, their hardness places teeth at significant risk.

Recognizing a Problem

Dental fractures are not always obvious. Many pets will continue eating and behaving normally despite discomfort.

Signs to watch for may include:

• Chewing on one side

• Avoiding harder treats or toys

• Dropping food while eating

• Pawing at the mouth

• Sensitivity when the face is touched

  
  

In some cases, there may be no visible signs at all, which is why routine oral examinations are so important.

Why Early Evaluation Matters

When a fracture exposes the pulp (the inner, living portion of the tooth), it allows bacteria to enter. This can lead to:

• Infection

• Abscess formation

• Ongoing oral pain

Left untreated, these conditions can progress and impact overall health.

Treatment options—such as root canal therapy or extraction—are most effective when addressed early.

Safer Chewing Alternatives

Not all chewing is harmful. The goal is to select materials that are durable yet forgiving.

We generally recommend:

• Rubber toys that have some flexibility

• Veterinary-approved dental chews

• Products that can be slightly indented with a fingernail

A helpful guideline: if an item is rigid enough that it would hurt if tapped against your own teeth, it is likely too hard for your pet.

Our Approach

At Tribeca Veterinary Dentistry, we emphasize prevention, early detection, and minimally invasive treatment whenever possible.

If you have questions about appropriate chew toys or are concerned about a potential dental injury, we are happy to help guide you.
