It can happen, but it is uncommon. Freeze-dried liver shatters into small fragments rather than becoming sticky, which means it is less prone to lodging in teeth than semi-moist or sticky treats. If pieces are stuck, they will typically dissolve with normal saliva flow within minutes. Pre-breaking pieces reduces the chance of any larger fragment getting wedged between teeth.

Why freeze-dried treats are less likely to stick
Sticky or semi-moist treats — soft jerky, cheese treats, peanut butter biscuits — are the worst offenders for lodging between teeth because their soft, adhesive texture conforms to dental surfaces and stays put. Freeze-dried liver does the opposite: it shatters into dry, non-adhesive fragments that do not have the surface chemistry to bind to enamel.
The remaining concern is a large fragment that physically wedges between two closely spaced teeth or in a gap from a missing tooth. This is more about geometry than stickiness. A dry fragment that is exactly the wrong size can wedge mechanically even without being sticky.
When it does happen: what to do
If you see a fragment visibly wedged between your dog's teeth, the simplest first step is to wait a few minutes. Saliva will rehydrate the fragment, causing it to soften and either dislodge on its own or become easy to remove. Most fragments that are truly freeze-dried (not rehydrated) will start softening in 2–5 minutes of saliva exposure.
If the fragment is still stuck after a few minutes and causing obvious discomfort (the dog pawing at the mouth, rubbing the face, or showing difficulty closing the jaw), you can use a soft toothbrush or your finger to gently work the piece loose. Do not use sharp objects in a dog's mouth. If you cannot remove it and the dog is uncomfortable, a vet visit for a quick manual removal is the right call.
Dogs more prone to this issue
Small breeds with dental crowding (Yorkies, Chihuahuas, Shih Tzus, and other toys) often have teeth that are more tightly packed relative to jaw size, leaving less space between teeth. This makes any type of treat fragment more likely to become wedged. Pre-breaking treats into very small bits is especially important for these breeds.
Dogs with missing teeth, extraction sites, or large interdental gaps from dental disease can occasionally trap fragments in those spaces. For dogs with active dental disease, your vet's guidance on appropriate treats should take precedence over general recommendations.
Prevention through piece size management
The practical solution is piece size. Pieces smaller than the gap between your dog's teeth cannot get lodged there. For toy breeds, crumble or pea-sized broken pieces are the safest format. For medium and large dogs, piece size is rarely an issue. Break pieces to an appropriate size before training sessions, and you remove the mechanism for this problem to occur.
When to check with your vet about dental concerns
If your dog is regularly pawing at the mouth after treats, showing reluctance to chew, dropping food from the mouth, or having visible difficulty eating, these may indicate dental pain unrelated to treat-lodging. Annual dental assessments (more frequent for small breeds) are recommended by most veterinary organizations. A dog with active dental pain should have a dental evaluation before you continue treat use of any kind.
