Puppy teething is the developmental process during which a puppy’s deciduous (baby) teeth fall out and are replaced by permanent adult teeth. This typically begins around 3–4 months of age and is usually complete by 6–7 months. During this time, puppies experience sore, itchy gums that drive an intense need to chew — making management essential for both puppy comfort and household sanity.
What Is Puppy Teething?
Puppies are born toothless. By 3–6 weeks of age, their 28 baby teeth (also called deciduous, milk, or primary teeth) have erupted. These teeth are small, sharp, and needle-like — which is why puppy bites feel so painful despite puppies being tiny.
Starting around 12–16 weeks of age, the baby teeth begin to fall out as the permanent adult teeth push upward through the gums. This process continues until all 42 adult teeth are in place, usually by 6–7 months. The sequence typically runs: incisors first, then canines (fangs), then premolars, and finally molars.
The teething process causes genuine discomfort — inflammation, soreness, and pressure in the gums — which is why puppies chew on everything they can find. This is not bad behavior; it’s a biological response to relieve pain. Understanding this helps owners respond with empathy and appropriate management rather than frustration.
Signs and Symptoms of Puppy Teething
Recognizing teething symptoms helps owners distinguish normal developmental behavior from potential health issues:
- Increased chewing: Puppies chew furniture legs, shoes, clothing, hands, and anything else within reach — with greater intensity than before.
- Drooling: Teething stimulates saliva production, so expect more drool than usual.
- Finding baby teeth: You may notice tiny white teeth on the floor, in toys, or even swallowed (this is normal — it won’t harm the puppy).
- Red or swollen gums: The gum line around emerging teeth can look inflamed and feel tender.
- Reduced appetite: Sore gums can make eating hard kibble uncomfortable; some puppies eat less or more slowly.
- Whimpering or fussiness: Mild discomfort can make puppies momentarily irritable or clingy.
- Mild bleeding: A tiny amount of blood in saliva or on chew toys when a tooth is lost is normal.
Why Puppy Teething Matters for Pet Owners
Teething is not just about discomfort — it has lasting implications for your dog’s adult dental health. If baby teeth don’t fall out properly, they can cause what’s called “retained deciduous teeth,” where the baby tooth stays alongside the incoming adult tooth. This creates overcrowding, abnormal bite alignment, and accelerated tartar buildup — all of which can lead to painful dental disease requiring extraction, sometimes costing $500–$1,500 or more.
Additionally, how owners respond during teething shapes long-term chewing habits. Puppies that learn what’s appropriate to chew now are far less likely to destroy furniture as adult dogs. This is the critical window for bite inhibition training and teaching chewing boundaries.
Scheduling a vet check around 5–6 months is smart — your vet can confirm all baby teeth have fallen out and identify any retained teeth before they cause problems. Many dogs are also spayed or neutered around this age, making it a convenient combined visit.
Best Practices for Managing Puppy Teething
- Provide appropriate chew toys: Offer a variety of textures — rubber chews (like KONG toys), nylon chews, and rope toys. Rotate them to maintain interest. Avoid hard bones that could fracture emerging teeth.
- Freeze toys for relief: Soak a rope toy or fill a KONG with low-sodium broth, then freeze. The cold soothes inflamed gums the same way an ice pack helps a toothache.
- Puppy-proof your home: Remove or protect anything you don’t want chewed — power cords, shoes, furniture legs, houseplants. Use bitter apple spray on surfaces you can’t move.
- Redirect, don’t punish: When your puppy bites you or chews something off-limits, calmly redirect to an appropriate toy. Yelling or punishment confuses puppies and damages trust.
- Practice bite inhibition: When a puppy bites too hard, yelp sharply and withdraw attention for 30 seconds. This mimics how littermates teach bite pressure limits. Consistent puppy training reinforces these lessons.
- Soften food if needed: If your puppy is eating less due to sore gums, add warm water to dry kibble to soften it temporarily.
- Check for retained teeth at 6 months: Have your vet examine the mouth to ensure all baby teeth have been replaced. Don’t wait — retained teeth need prompt extraction.
