When should you see a vet?

Reddened gums should be looked at by your vet. See your vet soon if:

the mouth or cheek is swollen, possibly with pus,
your dog stops eating or shows clear pain when chewing,
teeth are loose or the gums bleed heavily.

Gum inflammation (gingivitis) shows as red, swollen gums, bad breath and sometimes bleeding. It is usually caused by plaque. Caught early, gingivitis alone is considered reversible, so a visit to the vet is worthwhile.

How does gum inflammation develop?

Bacteria multiply in plaque. If plaque stays on the gum line, it irritates the gums and they become inflamed. Over time the plaque hardens into tartar, to which even more plaque sticks. In small breeds with closely spaced teeth, this often happens earlier.

How do you recognize gum inflammation?

red line along the gum margin
swollen gums that bleed easily
Bad breath
increased drooling or careful chewing

What can it lead to?

If the inflammation is left untreated, it can spread to the tissues that hold the teeth in place. This is called periodontitis. Teeth can loosen and be lost. According to the guidelines of the US veterinary hospital association AAHA, most dogs already have periodontal disease by the age of three.

What happens at the vet?

The vet examines the teeth and gums and decides which treatment is needed. Tartar is usually removed under anesthesia.

What you can do in everyday life

Brush your dog’s teeth ideally every day with a dog toothbrush and dog toothpaste.
Get your dog used to it slowly, with just a few seconds and lots of praise.
Suitable chews complement dental care, but they don’t replace brushing.
Look into your dog’s mouth once a week.

Frequently asked questions about Gums

How do I recognise gum inflammation?

By reddened, swollen gums, bad breath and sometimes bleeding. Some dogs also eat less or avoid hard chews.

Is it dangerous?

Left untreated, the inflammation can damage the tissues that hold the teeth in place, and bacteria can enter the bloodstream. So have it looked at by your vet.

What is the difference from periodontitis?

Gingivitis affects the gums; in periodontitis, the inflammation spreads to the tissues that hold the teeth in place.

What can I do day to day?

Look in your dog’s mouth regularly and ideally brush the teeth every day with dog toothpaste. Your vet can show you how to get started.
