Puppy Teething: When Baby Teeth Fall Out & How to Help

Bottom line: Puppy teething runs from about 3 to 6 months, when 28 baby teeth give way to 42 adult teeth. Soft chew toys and a weekly peek at the mouth keep it comfortable — but a baby tooth that lingers next to an adult tooth, or bleeding you can't stop, means a vet visit.

When the teeth actually arrive and leave

Dogs follow a fairly predictable timeline:

• 2-4 weeks: The 28 deciduous (baby) teeth erupt. You rarely notice because Mom and littermates are the main concern then.
• 3-4 months: Adult teeth start pushing from below, and baby teeth begin to loosen and fall out. This is the peak chewing phase.
• 5-6 months: Most puppies have their full set of 42 adult teeth. Some small breeds finish closer to 7 months.

You will occasionally find a tiny tooth on the floor, but most are swallowed during meals — normal and harmless. What you *should* watch for is the opposite: a baby tooth that refuses to leave.

Why teething hurts (and how puppies act)

Adult teeth erupting under baby teeth put pressure on the gums, and that is genuinely uncomfortable. Typical behavior:

1. Relentless chewing on anything handy — shoes, chair legs, your hand.

2. Drooling a bit more than usual, sometimes with tiny blood specks on toys.

3. Grumpy or distracted eating, especially with hard kibble.

4. Mild gum redness along the tooth line.

None of this is dangerous by itself. It is the dog version of a toddler with molars coming in. The job is to redirect the chewing and ease the soreness, not to medicate it.

Teething vs. something else

Not every mouth problem at this age is teething. Tell them apart so you do not miss a real issue:

• Normal teething: mild gum redness, heavy but purposeful chewing, tiny blood specks on toys, behavior otherwise bright and hungry.
• Not teething: one specific tooth looks broken or discolored, the puppy yelps when you touch the muzzle, swelling on the jaw, or bad breath that is strong and sour rather than faint. Those point to injury or infection and deserve a vet look.
• Double teeth: if you see a baby tooth and the adult tooth side by side in the same spot, that is a retained baby tooth (covered below), not a phase to wait out.

When in doubt, a 30-second look from your vet costs little and rules out the scary stuff.

How to soothe sore gums

• Chill a rubber chew toy in the fridge (not the freezer — too hard can crack a tooth). The cold numbs the gums the way a teething ring helps a baby.
• Frozen carrot or ice cube under supervision: a frozen baby carrot is a classic low-calorie chew that many puppies love. Pull it once it gets small enough to swallow whole.
• Soft food days: Mix a little warm water into kibble on rough days so eating does not feel like sandpaper.
• Frozen wet washcloth: Twist a clean, damp washcloth, freeze it, and let the puppy gnaw it. Cheap and effective.

Rotate toys so the novelty keeps their interest off your furniture. For a full daily routine, see our dental care guide.

Chew toys: what is safe, what is not

Safe: rubber teething rings, soft puppy-specific Nylabone, frozen carrots, rope toys under watch, stuffed-and-frozen Kongs.

Not safe during teething: antlers, hooves, raw bones, hard nylon for adults, ice cubes given whole and unsupervised (choking), and anything that does not yield when you press a fingernail into it. If you would not press it into your own knee, it is too hard for a pup with soft new teeth.

The goal is to satisfy the urge, not to test enamel. Picks suited to this stage are in our shop.

When to see a vet

This is general guidance, not a diagnosis. Your veterinarian is the only one who can confirm what is happening in your puppy's mouth.

Setting up the adult teeth

The habits you build now pay off for years. Once the adult teeth are in:

• Start a daily or every-other-day tooth-brushing routine with dog toothpaste (never human paste — fluoride and xylitol are toxic to dogs).
• Keep professional dental checks part of annual wellness visits.
• Use the dental care guide to pick a maintenance plan that fits your breed — small and flat-faced dogs are highest risk for early disease.

Teething is a short, messy few months. Handle it with cold chews and patience, and you set your dog up for a healthier mouth for life.
