Puppy teething is the natural process that turns a mouthful of tiny baby teeth into a full adult set. It usually runs from around three weeks of age to about six or seven months, and it explains most of the frantic chewing, drooling, and mouthing new owners notice. The soreness is real, but it is normal. Knowing the timeline and having the right chew options ready makes the whole stage calmer for you and far more comfortable for your puppy.
This guide summarizes established veterinary and American Kennel Club (AKC) guidance on canine dental development, along with the widely accepted, welfare-first approach to handling and bite work. It is an editorially researched overview, not a substitute for your own veterinarian, so any dental concern specific to your dog belongs in front of a professional.
What Is Puppy Teething and Why It Happens
Puppies are born without visible teeth. Over the first weeks of life, they grow 28 deciduous teeth, commonly called baby or milk teeth. These are temporary. As the jaw develops, those 28 baby teeth are pushed out and replaced by 42 permanent adult teeth: incisors at the front, pointed canines, premolars, and molars toward the back.
Teething refers to both parts of this cycle: the eruption of baby teeth early on, and the later loss of those teeth as the adult set breaks through. The gums stretch and inflame as new teeth move through the tissue, which is why they feel sore. Chewing puts pressure on aching gums and helps loosen baby teeth, so a teething puppy chews almost everything within reach.
None of this signals illness. It is a predictable developmental phase, and understanding it removes a lot of the worry that comes with finding a bloody chew toy or a wobbly tooth.
Puppy Teething Timeline by Age
The teething timeline is fairly consistent across breeds, with a few weeks of variation on either end. Knowing what age puppy teething tends to hit each stage helps you tell normal progress from a problem.
- Weeks 2 to 4: Baby teeth begin erupting through the gums. Puppies are still nursing at this point, and breeders often notice the first sharp incisors here.
- Weeks 5 to 8: All 28 deciduous teeth are usually in place. This is often when puppies go to their new homes, already equipped with needle-sharp little teeth.
- 3 to 4 months: The baby teeth start falling out, beginning with the incisors at the front of the mouth. Adult incisors move in behind them.
- 4 to 6 months: Canines, premolars, and molars come through. This is typically the most intense chewing window.
- Around 6 to 7 months: Most puppies have a complete set of 42 adult teeth.
Larger and giant breeds sometimes finish slightly later, and small breeds occasionally hold onto baby teeth longer. If your puppy is well past seven months and still appears to be teething, that is worth a mention at the next vet visit.
Which Puppy Teeth Fall Out (and in What Order)
Puppies lose all 28 baby teeth. The question of what puppy teeth fall out first has a reliable answer: the small incisors at the very front of the mouth go first, usually around three to four months. The canines, the long pointed teeth, and the premolars follow as the weeks pass.
So what puppy teeth do dogs lose overall? Every deciduous tooth is temporary and gets replaced. The adult mouth adds molars that the baby set never had, which is part of why the count jumps from 28 to 42.
Owners often expect to find a small pile of lost teeth around the house and worry when they never appear. Most baby teeth are simply swallowed while eating or chewing, and that is completely harmless. Finding the occasional tooth on the floor or embedded in a chew toy is normal too. Either way, there is nothing to collect or clean up.
What Puppy Teething Looks Like: Signs to Watch For
Knowing what does puppy teething look like helps you respond calmly instead of panicking. Common, expected signs include:
- A sharp increase in chewing and mouthing
- Extra drooling
- Small spots of blood on toys, chews, or bedding
- Visibly missing, loose, or wobbly teeth
- Mild gum swelling or redness
- Fussiness, or a temporary dip in appetite around the days a tooth is coming through
These come and go over several months and rarely need any intervention beyond appropriate chews and patience.
A few signs deserve a veterinary look rather than a wait-and-see approach. A baby tooth that has not fallen out while the adult tooth is already erupting beside it is called a retained deciduous tooth, and it can crowd the adult teeth or trap food and bacteria. Persistent bad breath, a broken or cracked tooth, obvious pain when eating, heavy bleeding, or adult teeth that meet abnormally when the mouth closes (a bite alignment problem known as malocclusion) all warrant professional attention. These are the moments to call, rather than manage at home.
How Long Puppy Teething Lasts
For most dogs, teething spans from about three weeks of age to roughly six or seven months, though the loudest phase for owners is the four-to-six-month stretch when adult teeth are pushing through fast. Breed plays a role: some smaller breeds wrap up a little earlier, while large and giant breeds may take a few extra weeks.
Teething should be fully complete once all 42 adult teeth are in and settled. If the bite looks off after that, with teeth that overlap oddly or a lower jaw that sits noticeably forward or back, have a veterinarian assess it. Some misalignments are cosmetic and harmless; others affect chewing or cause teeth to rub, and those are easier to address earlier than later.
How to Soothe Teething Pain and Discomfort
What helps puppy teething most is giving the gums safe, satisfying pressure and a bit of cold. A few reliable options:
- Durable rubber teethers and chew toys sized for your puppy’s mouth. Too small is a choking risk; aim for something they cannot fit entirely inside their mouth.
- A chilled or frozen wet washcloth, twisted and lightly frozen, gives cold relief and a chewy texture.
- Frozen carrots work as an inexpensive, low-calorie chew for many puppies, offered under supervision.
- Freezable teething toys designed to be chilled hold cold longer than a room-temperature toy.
Just as important is what to avoid. Very hard items can fracture developing teeth: skip real antlers, hard nylon bones, cooked bones, and hooves. Whole ice cubes are harder than many owners assume and can chip a tooth, so slushy or softer cold options are safer. Before giving any teething gel, pain product, or supplement, check with your veterinarian, since some human products are unsafe for dogs.
How to Stop Teething Biting and Redirect Mouthing
Sharp puppy teeth on human skin is one of the hardest parts of this stage, and it is where training and teething overlap. Reward-based, force-free handling is the widely accepted, welfare-first approach, and it works well here.
The goal is bite inhibition: teaching a puppy to control the force of its mouth. When teeth touch skin, calmly stop the interaction for a moment, then offer an approved chew toy the instant the puppy redirects. The pattern you want to build is simple and consistent: skin means fun pauses, toy means fun continues. Reward calm mouthing on the toy with attention and praise.
Consistency across everyone in the household matters more than any single technique. Avoid rough hand play, tug near the face, or wiggling fingers, all of which teach a teething puppy that hands are toys. Keep a chew within arm’s reach so redirection is instant rather than a scramble.
Teething handling folds naturally into early routines. Getting the timing of this right connects to when to start puppy training, which begins gently the day your puppy comes home, not months later.
Protecting Your Home and Your Puppy During Teething
A teething puppy will chew things it should not, and some of those things are dangerous. Puppy-proofing reduces both property damage and the risk of a swallowed object causing a blockage. Move electrical cords, shoes, small objects, and toxic plants out of reach.
Environmental management does the heavy lifting. A crate or pen gives your puppy a safe zone stocked with approved chews when you cannot supervise directly. This same structure supports house-training and a predictable daily rhythm, and a consistent puppy sleep schedule tends to reduce the overtired, extra-nippy behavior that shows up late in the day.
Frequently Asked Questions
Why are my puppy’s teeth so sharp?
Baby teeth are thin and needle-like partly because puppies have weak jaws. The sharpness gives them effective bite feedback during play, which is exactly how they learn to soften their mouth before the stronger adult teeth arrive.
Why is my puppy teething so bad?
Intensity varies by individual and often peaks when several adult teeth erupt at once, usually in the four-to-six-month window. A puppy that seems to be teething harder than expected simply may have more teeth moving at the same time. Ongoing distress, refusal to eat, or bleeding beyond minor spotting is worth a vet call.
Should I remove a loose baby tooth?
Leave loose teeth alone. Pulling a baby tooth can break the root or damage the developing adult tooth beneath it. Let them fall out naturally, and if one stays put while the adult tooth is already in, have a veterinarian evaluate it rather than removing it yourself.
Practical takeaway: Stock two or three correctly sized chews, keep one within reach for instant redirection, skip anything hard enough to crack a tooth, and mark your calendar to check the bite around seven months. Everything else is patience while nature swaps 28 baby teeth for 42 adult ones.
