Pets are remarkably skilled at hiding pain or discomfort, which often makes it difficult for owners to know when something is wrong. One of the most common and overlooked health problems in dogs and cats is dental disease. If untreated, dental disease can lead to chronic pain, tooth loss, and even impact the heart, liver, and kidneys.
The good news is that there are early signs that can help you recognise potential problems before they become more serious. Here are five key indicators your pet may be developing dental disease and what you can do to protect their health.
1. Bad Breath That Does Not Improve
While occasional “pet breath” is normal, persistent foul odour is one of the earliest signs of dental disease. The smell often comes from bacteria under the gumline, which can cause inflammation and infection. If ignored, bacteria can even enter the bloodstream and harm other organs. If your pet’s breath makes you hesitate to get close, it is time for a dental check-up.
2. Visible Tartar or Discoloured Teeth
Tartar, which forms when plaque hardens, often appears as yellow or brown buildup along the gumline. Tartar allows bacteria to thrive, damaging gums and surrounding tissues. Once it develops, brushing alone cannot remove it and a professional veterinary dental clean is required. Discoloured or darkened teeth may also suggest decay or a dead tooth. Early treatment gives the best chance of saving the tooth.

3. Red or Bleeding Gums
Healthy gums should be smooth and pale pink. Red, swollen, bleeding, or receding gums are often signs of gingivitis, which is the first stage of periodontal disease. Some pets may bleed after chewing toys or eating. Because gum condition strongly reflects oral health, any changes should be taken seriously.
4. Changes in Eating Habits
Dental disease can make eating painful, which may cause pets to chew slowly, drop food, or eat on only one side of the mouth. Some pets avoid dry food or chew toys, even though their appetite remains. If you notice a sudden preference for soft food or unusual chewing behaviour, dental discomfort may be the cause.
5. Pawing at the Mouth or Facial Sensitivity
Repeatedly pawing at the mouth, rubbing the face on the ground, or flinching when touched around the muzzle can be signs of dental pain. While these actions are sometimes mistaken for play, they may indicate discomfort from gum disease, infected teeth, or mouth ulcers.
When to See Your Vet
Even subtle changes can signal serious dental disease. If your pet shows any of these warning signs, book a dental health assessment. A full oral exam, and if necessary, dental x-rays, will help us detect issues before they become advanced and painful.
Our team can recommend the best treatment plan and guide you on preventative care. This may include professional dental cleaning and at-home strategies such as tooth brushing, dental chews, or diets formulated to reduce plaque.
