Your dog's mouth ages faster than you think—and if you’re not paying attention, small problems can build up into bigger health issues.

Research shows that as dogs grow older, major changes happen inside their mouth, making consistent dental care more important than ever.

Here are 3 key ways your dog’s mouth changes with age:

1. Their Oral Microbiome Becomes Less Diverse

   A 2024 study found that older dogs have less diversity in their oral microbiome—the natural balance of bacteria in their mouths.

   
   

   Researchers discovered that as dogs age, important "good" bacteria decline, leaving room for more harmful bacteria to grow.

   
   

2. Tartar and Plaque Build Up Faster

   With fewer beneficial bacteria, the bad bacteria take over—leading to more plaque and tartar buildup.

   
   

   Over time, this raises the risk of gum disease, bad breath, infections, and other serious dental issues.

   
   

3. Dental Health Affects Overall Wellness

   Poor dental health doesn’t stay just in the mouth.

   
   

   Changes in oral health can also influence your dog’s overall wellbeing, from digestion to heart health, especially as they age.

How You Can Help

Luckily, caring for your dog’s teeth doesn’t have to be complicated.

✔️ Daily brushing can help remove plaque and slow down tartar buildup.

✔️ Giving your dog a natural dental chew each day is an easy way to support cleaner teeth and fresher breath—just choose a single-ingredient chew for the best results.
