Why Do Hamsters Break Their Teeth?

Hamsters possess 16 teeth, four of which are called incisors – these teeth play an integral part in crushing and grinding food as well as filling their cheek pouches with food.

If a hamster’s teeth become overgrown, this could lead to problems for them when eating or could impede digestion. As soon as this occurs, a vet should be consulted in order to assist.

Hamsters teeth continue to develop throughout their lives. By eating and chewing items in their cages, their teeth wear down over time; if they bite down too forcefully on things such as cage bars or shelled nuts their teeth may be damaged permanently. Incisors (long front teeth) usually grow the fastest; when overgrown they can interfere with closing mouth for chewing as well as poke into gums or tongue causing cuts, bleeding, or break off altogether causing cuts and bleeding or break off altogether.

Hamsters may suffer tooth damage as a result of fighting. Syrian hamsters’ territorial behavior often leads to serious battles which lead to injury to both parties involved. If one hamster bites another on their face, jaw or cheek, this may result in broken or even detached teeth – potentially even leading to total removal altogether!

Hamsters can break their teeth through biting items in their cage. This behavior often indicates boredom or stress. Hamsters require toys in their cage to play with and chew on; branches instead of cage bars could help deter this behavior. In addition, bar chewing may indicate hunger; therefore it is crucial that their diet includes both fresh and dry food in order to avoid this scenario.

Broken teeth can be detrimental to hamster health as they cannot chew properly and feed themselves, potentially leading to infections and abscesses in their mouths. Should your hamster experience any tooth issues it is best to visit the vet immediately for treatment.

As soon as a hamster has broken teeth it is crucial that its behavior is closely observed. Look out for signs such as difficulty eating, drooling and unusual facial swelling; once these have appeared it’s time to schedule an appointment with an exotic veterinarian who can make sure its teeth are growing and wearing down correctly as well as provide liquid or food mixes from them to assist the healing process.


Preventative care for hamsters is key. Owners must ensure their pet receives an appropriate diet of nutritionally balanced pellets mixed with fresh produce such as seeds. Wood blocks should also be provided so hamsters can file down their teeth naturally while sugary treats should be limited or completely avoided as these could potentially cause dental issues.

Additionally, pet owners must ensure that their hamster has plenty of enrichment in its cage; boredom can lead to it gnawing at the bars and chipping or breaking their teeth. Enrichment activities could include running in a hamster ball or wheel or exploring various tunnels within its enclosure. It’s also beneficial for them to have companions in their cage, since hamsters enjoy having friends around.

Hamsters in the wild use their sharp incisors to break open shelled nuts such as Brazil nuts and walnuts – essential sources of nutrients – as part of their diet, and to defend themselves against predators or animals that catch them by surprise. A broken tooth could hinder this natural defense mechanism as well as cause oral and facial injuries.

Hamsters with overgrown teeth often develop an infected mouth that smells foul, as well as developing abscesses that can be painful and lead to further infections in other parts of their bodies. This condition must be treated immediately in order for optimal outcomes.

Vets may trim hamster teeth, and critical care mixes must be fed until damaged incisors have fully grown back. When feeding with a syringe, carefully remove it from its cage and hold it carefully while slowly pouring the liquid critical care mix directly into its mouth through your syringe. After each feeding and veterinarian appointment be sure to inspect its teeth.


Hamster incisor teeth develop throughout their lives, making it inevitable that some will break from time to time. Because they eat hard food like nuts and shelled nuts, hamsters need their incisors for cracking open shelled foods with chewing; unfortunately this causes their teeth to be worn away over time. Incisors also play an integral part in digging tunnels in their habitats in nature.

When one or two front incisors of a hamster’s teeth become broken, this typically isn’t a major problem; other healthy incisors will still allow the animal to bite and chew efficiently. However, multiple broken front incisors could make eating normal quite challenging for your hamster.

Hamsters often experience discomfort from broken teeth, so it is wise to monitor their mouth for any indications of trouble. Drooling may indicate tooth problems in hamsters but can also indicate other medical problems like infection or stress.

Feed your hamster foods rich in nutrients and minerals, such as fresh fruits and vegetables, oats, spelt, or seeds; this will ensure healthy teeth while providing them with essential vitamins and minerals.

Reducing access to chewable objects like wooden bars and blocks is one way to help stop teeth breaking in hamsters, as this allows them to explore the texture and taste of these objects without chewing on them for too long. When selecting chew toys made of non-toxic material it would be ideal. Sugary treats should also be avoided since sugar contributes to tooth decay that makes the teeth more brittle leading to additional incisor breaks as a result. For best results when caring for hamsters’ dental health it is wise to consult with an animal specialist veterinarian regarding care when handling their dental health needs.


Hamsters that cannot eat properly can develop serious health conditions, and their teeth play an integral part in chewing and eating. While a broken tooth might require treatment initially, most problems usually heal over time. Their incisors grow continually throughout their lives and eventually wear down as the animal chews on food or other objects like cage bars – however if something hits too hard the animal could potentially break one or more of its incisors and require extraction.

Broken incisors typically grow back at an equal rate as healthy ones, yet may not grow evenly across. A veterinarian can trim the teeth so they all meet at equal length and fit together correctly.

If your hamster experiences blood on its gums or the roof of its mouth, they should see their veterinarian immediately. Sharp points from broken teeth can lacerate oral cavity tissues and cause bleeding, infections and other health complications. Furthermore, an oral-nasal fistula might form between its mouth and nasal passageways that leads to illness in its future.

Your best defense against dental issues in your hamster is to provide them with plenty of chew sticks made of balsa wood or another lightweight and soft material for them to chew on. Also consider giving dog biscuits once every month to help wear down its teeth and stop them from growing too long.

Too long teeth in hamsters can get caught in their cheek pouches and lead to infections or abscesses, so to check whether yours are too long, remove it from its cage and gently pull on the skin on its neck until you can clearly see its teeth – they should have yellowish-brown coloring and should look as though they’re smiling.

If your hamster’s teeth are broken, a veterinarian can use surgical scissors to clip them back. Trimming should take place every three to six months depending on its age and diet; in the meantime provide your hamster with soft fruits, vegetables, dried or pelleted food and seeds as snacks until then.
