Puppy dental care month by month is a simple roadmap that pairs your home routine to your puppy's teething milestones, starting with gentle handling in the first weeks home and building toward a full daily routine by the time the adult teeth are in. Because a puppy's mouth changes so quickly, matching your care to each stage keeps things age-appropriate and effective. We have spent over 25 years at Ark Naturals helping owners get the timing right, so here is how the first year tends to unfold.
Months 2 to 3 (around 8 to 12 weeks): foundation
Most puppies arrive home around eight weeks with a full set of 28 baby teeth. There is no brushing or chewing routine to start yet. The job now is desensitization. Spend a few seconds each day touching your puppy's muzzle, lifting a lip, and gently running a finger over the gums, always paired with praise. These tiny sessions teach your puppy that mouth handling is normal and rewarding.
This is also the time to schedule those early veterinary wellness visits, where your vet will look at the developing mouth and answer your questions.
Month 3 to 4 (around 12 to 16 weeks): first transitions
Around three to four months, baby teeth start to loosen and fall out, beginning with the incisors. You might find a tiny tooth or notice a small gap. Chewing usually picks up as gums get sore.
This stage is when age-appropriate care can begin. Our chews are formulated for dogs 12 weeks and up, so once your puppy crosses that mark you can introduce a daily brushless chew. The Brushless Toothpaste chew is the typical starting point, with the Soft Brushless chew offering a softer texture for tender gums. Use the DENTA-METER on the pack to choose the right size, and check with your veterinarian on timing. Our chews are USA-made with no artificial flavors or colors and carry an Asta-Shield astaxanthin coating as a source of antioxidant support.
You can also introduce a toothbrush now if your puppy is comfortable with handling. Start by letting them lick dog toothpaste, then brush a few teeth at a time.
Months 4 to 6: peak teething
This is the busy stretch. Adult incisors, canines, premolars, and molars arrive, and chewing typically peaks as those teeth push through. Keep a rotation of safe chew items on hand and redirect any inappropriate chewing to approved options.
Watch the canine teeth closely for retained baby teeth, where a baby tooth stays put beside the erupting adult tooth, creating a doubled-up look. This is most common in small breeds. If you spot it, flag it for your veterinarian rather than touching it yourself. The American Veterinary Medical Association's pet dental care information is a helpful companion as you navigate this phase.
Keep building the brushing habit and offering a daily chew. Consistency through these months sets the tone for the adult routine.
Months 6 to 7: the adult set arrives
By six to seven months, most puppies have all 42 permanent teeth, though some large breeds finish slightly later. With teething behind you, the focus shifts fully to prevention. Now is the moment to lock in a steady daily routine: brushing regularly, offering a daily chew, and doing quick weekly mouth checks.
This is also a good time to ask your veterinarian about long-term dental planning, including when professional cleanings might eventually fit in.
Months 7 to 12: building the lifelong routine
Through the rest of the first year, the goal is consistency. Plaque forms on teeth within hours of eating, so daily attention matters. Brush as often as you can, ideally daily, and lean on a daily chew for the days that get away from you. As your dog grows and needs become clearer, you might consider more advanced or targeted options. For smaller dogs, Protection+ is sized for the smallest mouths, and Soft Shield offers advanced protection. Let your vet's input guide any step-up.
Keep up regular veterinary visits, and continue your weekly look inside the mouth for bad breath, redness, or anything unusual.

Frequently asked questions
When should I start a dental routine with my puppy?
Begin gentle mouth handling as soon as your puppy comes home, around eight weeks. Brushing and age-appropriate dental chews can follow after 12 weeks, once your puppy accepts handling and your veterinarian agrees.
At what month do puppies finish teething?
Most puppies have their full set of 42 adult teeth by six to seven months of age. Some larger breeds finish a little later, which is normal.
What should I watch for during the peak teething months?
Watch for heavy chewing, which is normal, and keep an eye on the canines for retained baby teeth that create a doubled-up appearance. Persistent bad breath, swelling, or refusal to eat should prompt a call to your veterinarian.
How do I know which chew size to use as my puppy grows?
Use the DENTA-METER printed on the package to match the chew to your dog's current weight, and reassess as your puppy grows. Your veterinarian can confirm the right size and timing.
