Why Puppy Dental Care from Day One Matters
When you bring home a new puppy, your mind is on potty training, crate training, and socializing — not their teeth. But here's a fact that might surprise you: by age three, 80% of dogs show signs of periodontal disease, according to the American Veterinary Medical Association (AVMA). And the foundation for that outcome — good or bad — is laid during puppyhood.
Puppies have 28 deciduous (baby) teeth that begin erupting around 3 weeks of age. By the time your pup reaches 6 months, those baby teeth will be replaced by 42 permanent adult teeth. Every stage of this process presents an opportunity to build habits that will keep your dog pain-free and save you costly veterinary dental cleanings down the road.
The Veterinary Oral Health Council (VOHC) emphasizes that daily oral care is the single most effective way to prevent periodontal disease. Starting when your puppy is young means they'll accept toothbrushing, wipes, and dental chews as a normal part of their routine rather than something to resist.
This guide walks you through exactly what to do at every stage — from the first baby teeth to the arrival of adult teeth — so you can set your puppy up for a lifetime of healthy smiles.
Stage 1: Weeks 3–8 — Baby Teeth & First Socialization
What's happening in your puppy's mouth
Your puppy's baby teeth (incisors first, then canines, then premolars) begin erupting between 3 and 6 weeks of age. By 8 weeks, most puppies have a full set of 28 needle-sharp deciduous teeth. These tiny daggers are nature's way of ensuring puppies can begin eating solid food — and they're also why your hands and ankles are suddenly very interesting.
What you should do
Start handling early. Between 3 and 8 weeks, your puppy is in their prime socialization window. This is the perfect time to introduce mouth and gum handling. Gently lift your puppy's lips, touch their teeth and gums with your finger, and immediately reward with praise or a tiny treat. Do this for 10–15 seconds several times a day.
Introduce a training finger brush. Once your puppy tolerates finger handling, slip a silicone finger brush over your finger and let them lick a bit of pet-safe enzymatic toothpaste off it. You're not brushing yet — you're building positive associations. The American Kennel Club (AKC) recommends choosing a poultry or peanut butter-flavored toothpaste formulated for dogs (never human toothpaste, which contains xylitol, a deadly toxin for dogs).
Do NOT use toothpaste under 6–8 weeks of age. Stick to gentle finger massage with water or a tiny smear of plain pumpkin puree on the brush.
Product safety note
At this stage, avoid hard chews, bones, or anything your puppy could fracture a baby tooth on. Stick to soft silicone brushes and gentle gum massage. Our RunyePet Dental Finger Wipes for Dogs & Cats are a great option — they're soft, textured on one side for gentle cleaning, and require no toothpaste, making them ideal for the youngest puppies beginning at 8 weeks.
Stage 2: Weeks 12–24 — Teething & Losing Baby Teeth
What's happening in your puppy's mouth
This is the stage every puppy owner knows well: the teething phase. Starting around 12 weeks, your puppy's baby teeth roots begin to resorb, and the permanent teeth push through. This process — which the AVMA notes can cause significant discomfort — typically wraps up around 6 months.
You'll find tiny tooth-shaped rice-grain-sized teeth on the floor, in your puppy's bed, and sometimes in your shoe. This is completely normal. During this period, your puppy will chew more aggressively than at any other time in their life. It's how they relieve the pressure and discomfort of erupting adult teeth.
What you should do
Provide safe teething relief. Freeze a damp washcloth (twisted and frozen) for your puppy to gnaw on. Offer rubber teething toys designed for puppies. Chilled — not frozen — rubber toys are especially soothing.
Begin gentle brushing. The VOHC recommends brushing your dog's teeth daily. Start with a soft-bristled puppy toothbrush and enzymatic toothpaste. Focus on the outside surfaces of the teeth, using small circular motions. Aim for 30 seconds per side. If your puppy only tolerates 5 seconds, that's a win — build up gradually.
Monitor for retained baby teeth. As permanent teeth erupt, baby teeth should fall out naturally. If you see a double row of teeth (a baby tooth still present alongside the permanent tooth), contact your veterinarian. Retained deciduous teeth can cause misalignment, plaque traps, and eventual periodontal disease.
Check for signs of teething discomfort. Drooling more than usual, red and swollen gums, decreased appetite for hard food, and increased chewing on everything in sight are all normal signs. If your puppy refuses to eat entirely, has foul-smelling breath, or has visibly bleeding gums, consult your vet — these could signal a problem beyond normal teething.
Products that help during teething
For puppies 12 weeks and older, our RunyePet Dental Cleaning Kit for Dogs & Cats includes everything you need: a double-headed toothbrush with soft bristles, a finger brush for gentle gum massage, and a dental scraper for later use. The finger brush is especially useful during teething because you can feel exactly where your puppy is most sensitive.
Adding a dental supplement to your puppy's food can also help. Our RunyePet Dog Dental Cleaning Powder mixes easily into wet or dry food and contains natural ingredients that help reduce plaque buildup from the inside out — ideal for teething puppies who may not tolerate brushing every single day.
Stage 3: 6+ Months — Adult Teeth & Establishing a Routine
What's happening in your puppy's mouth
By 6–7 months, all 42 permanent adult teeth should be in place. Your puppy now has: incisors (12), canines (4), premolars (16), and molars (10). The molars at the very back are the last to arrive, which is why bad breath sometimes appears around this age — food gets trapped back there and your puppy hasn't learned to let you brush those hard-to-reach areas yet.
This is a critical transition point. The habits you establish between 6 and 12 months will determine whether your dog accepts daily dental care for the rest of their life — or fights it every time.
What you should do
Brush daily. By now, aim for a full two-minute brushing session once per day. The AVMA states that daily brushing is the gold standard for preventing periodontal disease. Use a soft-bristled brush or finger brush with VOHC-accepted enzymatic toothpaste.
Introduce dental wipes for maintenance. For days when brushing isn't practical (travel, late nights, post-walk exhaustion), dental wipes are an excellent backup. Our RunyePet Extra-Large Dental Finger Wipes are designed for adult-sized teeth and are textured on one side to mechanically wipe away plaque. They're infused with natural cleaning ingredients and require no rinsing — simply wipe each tooth surface.
Schedule your first veterinary dental exam. Your veterinarian should examine your dog's adult teeth to check for alignment issues, retained baby teeth, and early signs of dental disease. Some vets recommend the first professional dental cleaning between 1 and 2 years of age, but this varies by breed.
Provide appropriate dental chews. Look for products bearing the VOHC seal of acceptance, which means they've been scientifically proven to reduce plaque or tartar. Offer these after meals, not as meal replacements.
Inspect your dog's mouth weekly. Lift the lips and check for: yellow or brown tartar, red or bleeding gums, broken or chipped teeth, and any unusual growths or swelling. Catching problems early saves pain and money.
Breed-specific considerations
Small and toy breeds (Chihuahuas, Yorkshire Terriers, Pomeranians, Dachshunds) are especially prone to periodontal disease because their teeth are large relative to their jaw size, creating tight spacing where plaque accumulates. Brachycephalic breeds (Pugs, French Bulldogs, Boxers) often have crowded or rotated teeth that create extra plaque traps. If you own one of these breeds, be especially diligent about daily dental care starting from puppyhood.

| Dental cleaning powder | 12+ weeks | Mix into food; great backup for fussy puppies |
| Soft-bristled puppy toothbrush | 12+ weeks | Small head designed for puppy mouths |
| Rubber teething toys | 12+ weeks | Chill (don't freeze) for teething relief |
| VOHC-accepted dental chews | 6+ months | Wait until adult teeth are fully in |
| Dental cleaning kit | 8+ weeks | Use finger brush component first; graduate to toothbrush |
Common Puppy Dental Problems
Retained deciduous teeth
As mentioned above, when a baby tooth doesn't fall out and the permanent tooth erupts beside it, this creates a double row. This is most common in small breeds. Retained teeth trap food and plaque, accelerating periodontal disease. Treatment is extraction under anesthesia, typically performed during spay/neuter surgery. The AVMA recommends checking for retained teeth during every veterinary visit in the first year.
Malocclusion (bad bite)
Some puppies are born with misaligned jaws — an overbite (brachygnathism) or underbite (prognathism). While some breeds (Boxers, Shih Tzus, Bulldogs) are bred for underbites, severe malocclusions can cause pain, difficulty eating, and premature tooth wear. Your veterinarian can assess whether intervention is needed.
Fractured teeth
Puppies love to chew, but they don't yet know their limits. Chewing rocks, hard nylon bones, or metal crate bars can fracture a tooth. Fractured teeth that expose the pulp (the inner living tissue) are painful and require veterinary treatment — usually extraction or root canal therapy. Stick to puppy-appropriate chews that bend rather than break.
Halitosis (bad breath)
While "puppy breath" is famous for being sweet, truly bad breath in a puppy is not normal. It can signal plaque buildup, retained food, or — in rare cases — a foreign object lodged between teeth or a systemic issue. If your puppy's breath is persistently foul, schedule a veterinary exam.
Gingivitis
Red, swollen, bleeding gums are signs of gingivitis — the earliest stage of periodontal disease. The good news is that gingivitis is completely reversible with improved dental care. The VOHC notes that daily brushing, combined with dental wipes and VOHC-accepted products, can reverse gingivitis within 2–3 weeks in most dogs.
FAQ
When should I start brushing my puppy's teeth?
You can start as early as 8 weeks old. Begin by letting your puppy lick a small amount of pet-safe enzymatic toothpaste from a silicone finger brush. Don't worry about actual brushing at first — the goal is to build positive associations. Gradually increase to gentle circular motions on the outside surfaces of the teeth over the following weeks.
How often should I brush my puppy's teeth?
The Veterinary Oral Health Council (VOHC) and the American Veterinary Medical Association (AVMA) both recommend daily brushing as the gold standard. If daily brushing isn't possible, aim for at least 3–4 times per week. Every-other-day brushing is significantly more effective than sporadic brushing, and daily brushing is always the goal once adult teeth are fully in.
Are dental wipes as effective as brushing for puppies?
Dental wipes are an excellent supplement to brushing but not a complete replacement. Wipes mechanically remove plaque from tooth surfaces and are especially useful for puppies who resist the toothbrush, for travel, or for quick cleanings after meals. The mechanical friction of a wipe against the tooth surface is the key — it disrupts the plaque biofilm before it mineralizes into tartar. For the best results, use wipes in combination with daily brushing and consider adding a dental cleaning powder to your puppy's food for comprehensive care.
What should I do if my puppy's baby tooth doesn't fall out?
If you see a permanent tooth erupting while the baby tooth is still firmly in place (a "double row"), contact your veterinarian. Retained deciduous teeth are common in small breeds and should be addressed early. Your vet will likely recommend extraction, often performed during the spay/neuter procedure. Delaying treatment can lead to misalignment, plaque accumulation, and periodontal disease in the adjacent teeth.
Can I give my puppy dental chews?
Yes, but only once your puppy has their full set of adult teeth — typically around 6+ months of age. Before that, hard dental chews can fracture baby teeth or hurt sensitive teething gums. Once adult teeth are in, look for VOHC-accepted dental chews appropriate for your puppy's size and chewing style. Always supervise your puppy with any chew product.
My puppy's gums are bleeding — is that normal?
A tiny amount of pink-tinged saliva during the first few brushing sessions is normal, especially if your puppy has mild gingivitis. However, significant or persistent bleeding from the gums is not normal and should be evaluated by a veterinarian. It could indicate gingivitis, a retained tooth fragment, a foreign object, or — in rare cases — a clotting disorder. If your puppy's gums bleed when they eat hard food or play with toys, schedule a veterinary exam.
Do I need to brush the inside (tongue side) of my puppy's teeth?
For most dogs, focusing on the outside (cheek side) surfaces is sufficient. The tongue's natural movement across the inside surfaces helps keep those areas relatively clean. That said, if your puppy tolerates it, a quick pass along the inside surfaces never hurts. The most important areas are the upper molars and canines — these accumulate the most plaque and tartar.
What toothpaste brands are safe for puppies?
Only use toothpaste specifically formulated for dogs. Dog toothpastes are enzymatic (they contain enzymes that help break down plaque) and are available in pet-safe flavors like poultry, beef, and peanut butter. Never use human toothpaste — it contains xylitol (highly toxic to dogs), fluoride (harmful if swallowed in quantity), and foaming agents that dogs will ingest. Look for products with the VOHC seal of acceptance for guaranteed efficacy.
The Bottom Line
Puppy dental care doesn't need to be complicated or expensive. The formula is simple: start early, be consistent, and use the right tools for each stage.
Begin with gentle finger handling at 3–8 weeks. Introduce a finger brush or dental wipes at 8 weeks. Graduate to a soft toothbrush and enzymatic toothpaste during the teething phase (12–24 weeks). By the time your puppy's adult teeth arrive at 6 months, a daily dental routine should be second nature to both of you.
Our RunyePet Dental Cleaning Kit and Dental Finger Wipes are designed to grow with your puppy — from those first tentative gum massages through to daily adult maintenance.
