Dog Dental Chart: Puppy Teeth, Adult Teeth, and What to Check

A dog dental chart is useful for orientation, not for diagnosing a mouth. It can help you place puppy teeth in a broad first-year window, compare baby and adult tooth counts, and decide what information to bring to your veterinarian. The chart answers “what stage might fit this age?” It does not answer “is this individual mouth healthy?”

Start With the Dog’s Two Tooth Sets

The MSD Veterinary Manual’s dog dental-development reference describes two normal sets: 28 deciduous, or baby, teeth and 42 permanent teeth. Permanent teeth usually begin appearing at around four to five months, and the permanent set is generally present by about seven months.

Those numbers give a useful map for a new puppy’s first year. They are not a deadline that every puppy reaches on the same day. The same reference notes that tooth eruption provides only an approximate age estimate, so a chart should add context to what you observe rather than overrule it.

If you are looking at a dog dental formula, use it to understand the transition between sets. Avoid turning the count into a home inspection project. A quick view of visible teeth cannot show the whole mouth, and a sore dog may not tolerate close handling.

Use the Puppy Range Without Calling It a Diagnosis

At four months, five months, or seven months, age can help you ask a more precise question. Record the puppy’s approximate age, whether eating seems comfortable, whether chewing has changed, and whether you noticed a tooth that looks missing, retained, broken, painful, or poorly positioned. This is a record for a professional conversation, not a pass-fail test.

Chewing may happen during teething, but chewing alone cannot establish that the mouth is developing normally. A puppy may also chew in other contexts. The safer interpretation is to pair the age range with comfort and eating, then leave the mouth assessment to a veterinarian when something does not fit the puppy’s usual pattern.

This is separate from choosing a brushing routine. The dog dental-care guide covers calm home maintenance and the boundary between brushing and professional care. A chart can orient the conversation; it cannot replace that care.

A Cat Dental Chart Is a Different Species Check

The cat version should not be copied from the dog version. The MSD Veterinary Manual’s cat dental-development reference describes 26 deciduous teeth and 30 permanent teeth. Permanent teeth usually begin appearing at around four to seven months of age.

That wider range is still a window, not a fixed finish line. If you are comparing a kitten’s dental chart with a dog’s, keep the species and age in the note. For a kitten, record eating comfort, mouth behavior, and the timing of any visible change instead of assuming the dog timeline applies. The cat dental-care article explains why home care and professional assessment remain separate decisions.

Turn the Chart Into a Calm Observation Note

Use three short lines rather than trying to count every tooth:

1. Age and species: write “puppy” or “kitten” and the approximate age.
2. Comfort and function: note eating, chewing, drooling, food dropping, and any change from the usual pattern.
3. Visible change: record a tooth that looks retained, damaged, poorly positioned, or different, without forcing the mouth open.

Bad breath is more useful when paired with a change in eating or mouth behavior. The American Veterinary Medical Association lists abnormal chewing, drooling, dropping food, reduced appetite, oral bleeding, or facial swelling alongside bad breath as reasons to contact a veterinarian. One sign does not identify a condition, and a fresher smell would not explain what is happening below the gumline.

Know When the Chart Stops Helping

Move from chart-reading to a veterinary call when the puppy or kitten has difficulty eating, repeated food dropping, oral bleeding, facial swelling, a damaged or poorly positioned tooth, marked drooling, or a sudden mouth-behavior change. Do not force a close look at a mouth that may be painful. Tell the clinic the species, approximate age, what changed, when you noticed it, and whether eating is affected.

If the mouth seems comfortable and the question is routine development, keep the note for the next wellness visit and ask what the veterinarian wants monitored. If you are uncertain, ask before brushing or changing food. Home dental care is maintenance between checks; the chart is a conversation aid, not a home dental examination.
