When Do Cats Lose Their Baby Teeth?

Most kittens lose their baby teeth between about 3 and 6 months, and usually have their full 30 adult teeth by 6 to 7 months.

If you are finding tiny teeth on the floor, seeing extra chewing, or noticing "double teeth," you are likely in the normal teething window. The key is knowing what is expected versus what needs veterinary attention.

Normal Tooth Timeline in Kittens

According to Cornell and VCA references, kittens develop two sets of teeth in life:

• 26 deciduous (baby) teeth
• 30 permanent (adult) teeth

Typical pattern:

| Age | Dental stage | |---|---| | 3-8 weeks | Baby teeth erupt | | 10-16 weeks | Baby incisors begin to fall out; adult incisors erupt | | 4-6 months | Adult canines and premolars erupt | | 6-7 months | Most kittens have all adult teeth present |

Common Teething Signs

Many kittens show mild, temporary signs:

• More chewing on toys or household objects
• Slight gum sensitivity
• Small amount of drooling
• Brief fussiness while eating harder food

You may never see the shed tooth because kittens often swallow them while eating.

What Is Not Normal

Call your vet if you notice:

• Persistent bad breath at a young age
• Refusal to eat or obvious oral pain
• Heavy drooling or oral bleeding
• Facial swelling
• Adult and baby teeth occupying the same spot for weeks

Retained Deciduous Teeth: Why It Matters

Retained baby teeth can trap food and bacteria, increase crowding, and alter bite alignment. Over time this raises periodontal risk and can injure soft tissues.

Treatment is usually extraction of the retained deciduous tooth by your veterinarian, often under anesthesia, to protect normal adult alignment (VCA (opens in new tab)).

Teething Care at Home

Simple steps help most kittens stay comfortable:

• Offer safe chew toys (not hard bones or brittle objects)
• Keep dangerous chew targets out of reach (cords, plants, strings)
• Feed texture your kitten can eat comfortably
• Start gentle mouth handling so brushing is easier later

Brushing During Teething

Dental training should begin early, but intensity should match comfort. If gums are very sensitive during active tooth replacement, use shorter sessions and ask your veterinary team when to resume regular brushing cadence.

Use pet-safe toothpaste only; never use human toothpaste.

Vet Dental Checks in the First Year

A routine kitten wellness exam should include oral checks so retained teeth, malocclusion, or early gingival inflammation are caught early. Early correction is easier and can reduce lifelong dental burden.

Bottom Line

Kittens normally lose baby teeth starting around 3 to 4 months and complete adult dentition by about 6 to 7 months. Mild chewing and drooling can be normal, but "double teeth," pain, or poor appetite deserves prompt veterinary evaluation.
