Most pet owners don't look inside their dog's mouth until something goes wrong — bad breath, drooling, or a sudden reluctance to eat. By then, dental disease has often already progressed to a painful stage. Learning how to perform a simple at-home mouth examination takes less than two minutes and can catch problems early when they are most treatable.
The American Veterinary Medical Association (AVMA) reports that periodontal disease is the most common clinical condition in adult dogs, affecting over 80% by age three. Yet most owners never examine their dog's mouth until symptoms are obvious. A monthly at-home check can be the difference between a simple dental wipe routine and a costly veterinary extraction.
When to Examine Your Dog's Mouth
- Weekly: For dogs with known dental issues, senior dogs, and small breeds prone to crowding
- Monthly: For healthy adult dogs with good dental habits
- Before vet visits: Note any changes to discuss with your veterinarian
- After behavior changes: If your dog stops eating kibble, drops food, or paws at the mouth
Step-by-Step Mouth Examination
Step 1: Prepare Your Dog
Choose a calm time of day. Have treats ready. Let your dog sniff your hands first. Begin by gently touching the muzzle, lips, and cheeks — areas your dog is already comfortable with. If your dog pulls away, slow down and practice just the outer-face touching for a few sessions before attempting the exam.
Step 2: Lift the Lips — Check the Front Teeth
Gently lift your dog's upper lip on one side, exposing the canine teeth and incisors. Look for:
- Yellow or brown tartar along the gumline — hardened plaque that requires professional removal
- Red or swollen gums (gingivitis) — the earliest stage of periodontal disease, still reversible with improved home care
- Bleeding along the gumline — a sign of active inflammation
- Chipped, fractured, or discolored teeth — broken teeth expose sensitive dentin or pulp, causing pain
- Loose or wobbly teeth — advanced periodontal disease or tooth root abscess
Step 3: Check the Back Teeth (Premolars and Molars)
Gently pull the corner of your dog's mouth backward (toward the ear). This retracts the cheek, exposing the upper and lower premolars and molars — the teeth most commonly affected by periodontal disease. Pay special attention to:
- The carnassial tooth (upper fourth premolar) — the large tooth near the back of the upper jaw. This is the most common site for tooth root abscesses in dogs
- Deep gum pockets — areas where the gum has pulled away from the tooth, creating a space that traps food and bacteria
- Foreign objects — sticks, bones, or grass awns wedged between teeth or embedded in the gum tissue
Step 4: Check the Lower Jaw and Tongue
Gently press down on your dog's lower jaw to open the mouth slightly. Look at:
- The underside of the tongue — look for ulcers, growths, or foreign objects
- The floor of the mouth — swelling under the tongue can indicate a salivary gland issue or abscess
- The hard palate (roof of the mouth) — check for burns from hot food, foreign objects, or growths
Step 5: Evaluate the Breath
Smell your dog's breath during the exam. While all dog breath isn't minty-fresh, certain odors signal specific problems:
- Sweet or fruity smell — may indicate diabetes, especially if accompanied by increased thirst and urination
- Fishy or garbage-like odor — often indicates advanced periodontal disease or tooth root abscess
- Metallic or bloody smell — active bleeding in the mouth from gum disease, a fractured tooth, or oral tumor
- Ammonia-like smell — may indicate kidney disease, as failing kidneys cannot filter waste products from the blood
What Normal Looks Like
| Feature | Healthy Appearance | Warning Sign |
|---|---|---|
| Gums | Firm, pale pink (or pigmented black for some breeds), no bleeding | Red, swollen, bleeding easily, receding from teeth |
| Teeth | White or slightly off-white, no visible cracks or chips | Yellow/brown buildup, chips, fractures, dark spots, looseness |
| Breath | Mild "dog breath" — not offensive | Persistent strong odor that doesn't improve with cleaning |
| Saliva | Clear and watery | Thick, stringy, bloody, or excessive drooling |
| Tongue | Moist pink surface, smooth texture | Ulcers, growths, swelling, discoloration, excessive coating |
What to Do If You Find a Problem
- Mild tartar without red gums: Start or increase daily cleaning with RunyePet Dental Finger Wipes. Tartar buildup can be prevented from worsening with consistent mechanical removal.
- Red gums with bleeding: Begin gentle daily wiping with RunyePet Dental Finger Wipes and add RunyePet Dental Cleaning Powder to meals for enzymatic support. Schedule a veterinary dental check within 1-2 months.
- Loose teeth or visible abscess: Schedule a veterinary dental cleaning immediately. Loose teeth indicate significant bone loss that requires professional assessment and likely extraction.
- Chipped or fractured tooth: Contact your veterinarian. Fractured teeth may need extraction or root canal depending on how deep the fracture extends.
- Unusual growths or swelling: Schedule a veterinary exam. Oral masses require biopsy to determine if they are benign or malignant.

FAQ: Examining Your Dog's Mouth at Home
How often should I check my dog's mouth?
Monthly for healthy dogs with good dental habits. Weekly for senior dogs, small breeds, and dogs with known dental disease. Before each professional dental cleaning, note any changes to discuss with your vet.
My dog won't let me look in their mouth. What can I do?
Start slowly — just touch the muzzle and lips for several days while giving treats. Graduate to lifting the lip for one second, then two seconds. Use a "high value" treat that only appears during mouth exams. Never force the examination — a struggling dog can accidentally bite, and the stress creates negative associations.
Is it normal for my dog's gums to be black?
Yes! Many dogs have pigmented (black) gums, especially breeds like Chow Chows, Shar-Peis, and some Labrador Retrievers. Black gums are normal as long as they are firm and not swollen. What matters is the gum texture (firm vs. spongy) and whether there is bleeding.
Can I remove tartar myself at home?
No. Only a veterinarian can safely remove tartar during a professional dental cleaning under anesthesia. At-home tools for scraping tartar (dental scalers sold online) can damage tooth enamel and push bacteria into the gums. Use RunyePet Dental Finger Wipes to prevent new tartar from forming, but leave existing tartar removal to the professionals.
What does a dog tooth root abscess look like?
You may see a swollen lump under the eye (for upper teeth abscesses) or along the lower jaw (for lower teeth). The area may be warm, painful to touch, and may drain pus. Your dog may have a fever, loss of appetite, and reluctance to chew on that side.
Should I examine my dog's mouth after every meal?
Not necessary. A monthly systematic check is sufficient for most dogs. However, if your dog ate something unusual (sticks, bones, hard toys), it's wise to do a quick lip-lift check for lodged debris.
Conclusion
A two-minute monthly mouth examination is one of the most valuable habits you can develop as a dog owner. Combined with daily plaque removal using RunyePet Dental Finger Wipes and enzymatic support from RunyePet Dental Cleaning Powder, regular at-home checks help you catch dental problems early — before they become painful, expensive, and damaging to your dog's overall health.
Start today: grab a treat, lift your dog's lip, and see what their smile is telling you.
