A mouth check is 6 points, 60-90 seconds, once a week, and it ends with a 3-level grade that tells you whether to wait 6 months, book a dental in 4-6 weeks, or go now. Cats hide mouth pain, so the weekly 90 seconds is often the first time an owner notices a problem months old.

Why weekly, and why 90 seconds is enough

Gum disease moves faster than most owners expect. Plaque turns into tartar in 24-72 hours, gingivitis follows within 2-3 weeks, and by the time a cat drops food or chews on one side, the damage is usually at the root. A weekly check at 52 checks a year catches a red gum line at week 1 instead of at month 8, and 90 seconds covers all 6 points without a wrestling match.

Frequency matters for a second reason: a cat handled for 90 seconds every 7 days stays handleable. A cat checked once a year arrives at the clinic already defensive, and the exam becomes a sedation.

Set up in 60 seconds

Use daylight or a phone light held to the side, never straight into the eye. Sit the cat on a table at chest height, back toward you, with a towel under the paws for grip. One hand goes under the chin and lifts slightly; the other lifts the lip at the side, not the front. If 2 people are available, the second one holds the body and the check drops to 45-60 seconds.

Do not open the mouth wide on the first attempt. A cat jaw opens comfortably about 20-30 degrees, and forcing 60 degrees injures soft tissue in a 12-year-old cat with arthritis.

The 6 points, with seconds on each

  1. Lips and cheek lining, 10-15 seconds. Lift both sides and look for redness, ulcers, or a lump at the corner of the mouth.
  2. Gum line, 15-20 seconds. Run a fingertip along the gum above the upper canine on each side. A healthy line is pale pink and 1 mm wide; a red 2-3 mm band is grade 2.
  3. Outer tooth surface, 15-20 seconds. Look at the upper fourth premolar on each side, the big tooth that collects most tartar. Brown at the gum line is tartar, not food.
  4. Tongue and floor of the mouth, 10 seconds. Lift the tongue tip 1-2 cm; look for ulcers, a string of saliva, or a mass under the tongue.
  5. Hard palate, 5-10 seconds. Tilt the head back 20 degrees and look up; a cleft or a line of red dots is a finding.
  6. Breath and jaw, 10 seconds. Smell the breath at 10 cm, then run both hands along the jawline from the chin to the ear on each side, feeling for swelling or asymmetry.

The 3-level grade

Grade the worst point you found, not the average. The grade decides the next date, and the dates in the table are the ones most vets work with.

Grade 2 is the level where a 300-600 dollar cleaning prevents a 900-1,500 dollar extraction case 12-18 months later, and the cost breakdown puts both numbers next to food and litter. Grade 3 is not a cleaning; it is pain control and then a plan.

Home care between checks

Brushing is still the reference method: a soft pet toothbrush, 30-45 seconds a day, 5-7 days a week, angled 45 degrees at the gum line. Most cats accept it if the first 2 weeks are a finger and a taste of paste, ending at 30 seconds whatever happens. Brushing 3 days a week removes about 60% of the plaque that daily brushing removes; brushing 1 day a week removes very little.

Rinses and gels are a category of their own and only on a vet prescription, because the active agent and the strength have to match the gum condition and the cat, and a human mouthwash with alcohol or a high-strength antiseptic irritates the tissue it is meant to help. Never use a human rinse, and never increase the amount because the breath is worse.

What you must not do

  • Do not pry the mouth open with a finger between the canines. A cat can generate enough bite force at the back teeth to break a finger, and the reflex closing is faster than your hand.
  • Do not use a human toothbrush with hard bristles, or human toothpaste. Fluoride and xylitol are both toxic to cats, and the foam is not rinsed out.
  • Do not scrape tartar with a fingernail, a dental pick or a metal tool. Enamel is 0.5-1 mm thick and a 0.2 mm scratch becomes a cavity.
  • Do not grade on breath alone. A cat with grade 1 gums can have foul breath from the back of the mouth, and a cat with grade 2 can smell normal.
  • Do not check within 30 minutes of a meal. Food debris reads as tartar and the cat is more likely to gag.
  • Do not skip the check because the cat has no teeth left; gum inflammation and masses still happen with 0 teeth.

When the check ends the week and starts a visit

Six findings go to a vet rather than to next week: bleeding that lasts more than 24 hours after a check, a loose tooth, a mass or ulcer that was not there 7 days ago, drooling, eating on 1 side for 3 days or more, and weight loss of 5% or more in 8 weeks. Add a 7th for older cats: any new bad breath in a cat over 8 years, because kidney disease and diabetes both change breath before they change appetite.

Ulcers can also come from chewed plants; the household plant list covers what to move.

Dental work in cats almost always means anesthesia with X-rays, and bloodwork first. A 10-year-old cat needs a chemistry panel and a thyroid check before a dental, and that adds 1-2 days and 50-120 dollars to the plan. It is still the cheap path: a jaw fracture or a kidney hit from untreated infection costs 5-10 times more.

Your first check, in 4 moves

  1. Put a reminder every 7 days for 52 weeks, on the same day as the weight check.
  2. Do 1 full pass of the 6 points and grade the worst finding, not the average.
  3. Photograph the gum line on both sides at 2x zoom; the photo is what makes next month comparable.
  4. If the grade is 2 or 3, book the visit before you buy a toothbrush.

Frequently asked

My cat will not let me open its mouth. Can I still do this check?

Yes, and you should not force it. Five of the 6 points are visible with the mouth closed or barely parted: lift the lip at the side for the gum line and the outer teeth, look at the tongue tip, tilt the head for the palate, and smell the breath. If the mouth cannot be opened at all without pain, that is itself a finding and worth a visit within 1-2 weeks.

How often should a cat have a professional dental cleaning?

There is no single interval, which is why the weekly grade exists. A cat graded 0-1 with good home care often goes 12-24 months between cleanings, while a cat graded 2 needs one within 4-6 weeks regardless of age. Most vets decide from the gum line, the tartar cover and X-ray findings rather than from the calendar, and anesthesia risk is assessed with bloodwork first.

Is anesthesia-free dental cleaning a safe alternative?

It scales what is visible above the gum line and leaves the part that causes disease, which sits under the gum. It also cannot take X-rays, cannot probe pockets, and cannot treat a tooth that is already loose, so a cat with grade 2 or 3 disease can look cleaner and still be in pain. Most vets will not call it a substitute for a dental under anesthesia with imaging.
