What are signs my dog needs a dental checkup?

Last updated 23 September 2026 · How we write and check this

Short answer

Watch for visible yellow or brown tartar along the gumline, red or swollen gums, sudden reluctance to chew hard food or toys, pawing at the mouth, and breath that has noticeably worsened over a few weeks. Any one of these on its own is worth a look, and several together point more strongly to a checkup being due.

Visual signs to check for

Lift the lip and look along the gumline, particularly on the back molars, for a yellowish or brownish crust, and check whether the gums themselves look pink and healthy or red and slightly puffy. These visual checks take less than a minute and are worth doing every couple of weeks.

Behavioral signs that are easy to miss

A dog that suddenly starts favoring soft food over kibble, drops hard chews after a few bites when it used to finish them, or paws at its own face repeatedly may be dealing with tooth or gum discomfort rather than simply a change in preference.

Putting it together

One sign alone, like slightly worse breath, might just mean a brushing session or two is overdue. Multiple signs together, especially visible tartar plus reluctance to chew, are a stronger indicator that a professional dental assessment is due rather than something home care alone will fix.

Why catching signs early saves more than just discomfort

Addressing early tartar buildup or mild gum redness before it progresses generally means a simpler, shorter professional cleaning appointment, while waiting until signs are severe can mean a longer procedure and, in more advanced cases, tooth extractions, so early attention genuinely pays off both for your dog's comfort and for the scope of any future treatment.

Keeping a simple monthly reminder to do this quick visual and sniff check, even for a dog with no current concerns, builds the habit of noticing changes early rather than only checking once something has already become obviously uncomfortable for your dog.

Key takeaways

  • Visible tartar and red or swollen gums are clear visual signs worth checking every couple of weeks.
  • A sudden preference for soft food or reluctance to chew can signal mouth discomfort.
  • Several signs appearing together point more strongly toward needing a professional dental checkup.
