It's never too early to start thinking about your kitten's dental health, and getting it right now is far easier than teaching an adult cat new tricks later. This guide covers the whole kitten dental journey: teething, when to start brushing, safe products, and what to watch for as those adult teeth settle in.

When do kittens get their adult teeth?
Kittens are born without any teeth. Their first set of baby (deciduous) teeth erupts from around 3-4 weeks of age, and by 6-8 weeks they'll have a full set of 26. From about 11-12 weeks, these baby teeth start falling out to make way for permanent adult teeth, with a full adult set of 30 usually in place by 6 months of age.
This swap-over is called teething, and it's normal for kittens to get a bit mouthy, drooly, or off their food while it happens. We've covered signs, timing and home remedies in full in our kitten teething guide.
One thing worth flagging early: hold off on brushing while your kitten is actively teething - sore gums and a toothbrush don't mix well, and it can put your kitten off the whole process before you've even started.
When should I start brushing my kitten's teeth?
Once your kitten's adult teeth are all through, around 6 months of age, is the right time to start a proper daily brushing routine. You don't need to wait until then to get them ready for it though, and honestly, you shouldn't.
In clinic, the kittens who grow into the calmest adult patients for dental checks are almost always the ones whose owners started gently handling their mouth and lips from as young as 8-12 weeks, well before a toothbrush ever came into it. That early handling is what makes brushing feel normal rather than a wrestling match down the track.
How do I introduce tooth brushing to a kitten?
Go slowly and keep it upbeat. Kittens are much easier to train into a brushing routine than adult cats, they haven't yet learned to associate a toothbrush with something to avoid, so this early window is a genuine advantage. Starting with an adult cat instead? Our guide on how to brush your cat's teeth covers building trust from scratch.
A simple step-by-step approach:
- Get them used to touch first. Gently lift the lips and touch the gums and teeth for a few seconds, building up over several days. Reward them with praise or a high-value kitten treat.
- Introduce the taste. Let your kitten lick a cat-safe toothpaste off your finger.
- The finger rub: Gently massage a bit of toothpaste along their gumline and back teeth using your index finger, or a cotton tip.
- Introduce the toothbrush: Let them sniff and lick a soft kitten toothbrush or finger brush first without moving it around.
- Combine the brush and paste. Once comfortable with both, brush just the front teeth for a few seconds, then build up to the full mouth.
- Aim for daily. Daily brushing is the gold standard, though a few times a week still helps.
The most common mistake we see is owners trying to do all of this in one sitting and giving up the moment their kitten wriggles free. Little and often, with plenty of praise, beats one big battle.
What dental products are safe for kittens, and what should I avoid?
When caring for a kitten’s teeth, always choose items designed specifically for felines. Enzymatic cat toothpaste in appealing flavours like poultry or malt is the safest option because it is formulate to be swallowed safely. Pair this with a kitten-sized, soft-bristled toothbrush or a silicone finger brush to gently clean their tiny mouths. Kitten toys that encourage chewing are excellent too - chewing produces saliva which protects the teeth, while the chewing action scrapes the surface of the teeth, reducing plaque build-up. Always monitor your kitten when they are chewing on a toy or treat and replace any damaged products to ensure your kitten is not at risk of choking or swallowing foreign objects.
Dental treats can help reduce plaque between brushes, but they're best introduced around 10 months of age. Look for treats with the Veterinary Oral Health Council (VOHC) seal where possible.
Avoid:
- Human toothpaste, as ingredients like fluoride and xylitol are highly toxic and potentially fatal to cats
- Homemade baking soda pastes, which can cause gastrointestinal upset
- Hard bones
- Rawhide
- Hard chew toys
What should I watch for as my kitten's adult teeth come through?
Keep an eye out for retained baby teeth, where an adult tooth comes through but the baby tooth hasn't fallen out, this is one of the most common findings at a kitten dental check. Also watch for crowding or crooked teeth, as these are easier to manage the earlier they're spotted.
A little gum redness or mild bleeding during teething is normal. Ongoing bleeding, swelling, or a loose or damaged tooth outside the teething window is not, and is worth a vet visit.
What warning signs mean I should see a vet?
Book a check if you notice persistent bad breath, red or bleeding gums that don't settle, reduced appetite, pawing at the mouth, drooling more than usual, or a tooth that looks retained, broken, or out of place.
Kittens tend to show mask pain, often just quietly eating or grooming less rather than anything obvious. If in doubt, call your vet rather than wait to see if it resolves on its own.
What happens at a kitten dental check-up?
Once your kitten's adult teeth are in, around 6 months, a dedicated dental check is recommended, often timed alongside desexing and the final visit on your kitten vaccination schedule. Your vet will check for retained baby teeth, crowding, broken teeth, and bite alignment, and flag anything needing monitoring or treatment.
After this first check, six-monthly vet visits are the general recommendation as your cat grows into adulthood. Once your kitten graduates to a full adult routine, our cat dental care guide covers diet, treats, water additives, dental supplements and common problems, our toothbrushing for cats has a step by step guide, and our pet dental care guide has the basics for the whole household if you've got dogs as well as cats.
