Why Did My Adult Dog Lose a Tooth? A Quick Guide

Finding your adult dog’s tooth on the floor is a major red flag. Unlike puppies, when an adult dog loses a tooth, it signals a serious health issue that needs attention. Here’s what you need to know.

The #1 Cause: Periodontal Disease

Overwhelmingly, the reason is advanced dental disease. It’s a slow, painful process:

1. Plaque (a sticky film of bacteria) builds up on the teeth.
2. Plaque hardens into tartar, irritating the gums.
3. This leads to infection below the gumline, which destroys the bone and tissue that hold teeth in place.

By the time a tooth falls out, the disease is severe and your dog is likely in significant pain.

Other, Less Common Causes

• Trauma: Chewing on hard items like rocks, antlers, or hard bones can crack or break teeth.
• Health Issues: In rare cases, other medical conditions can impact oral health.

Warning Signs of Dental Trouble

Don't wait for a tooth to fall out. Look for these signs:

• Foul bad breath
• Red, swollen, or bleeding gums
• Yellow-brown tartar buildup
• Difficulty chewing or dropping food
• Pawing at the mouth or face
• Facial swelling

How to Prevent Tooth Loss

1. Daily Brushing: Use a dog-specific toothpaste to remove plaque. This is the single most effective thing you can do.
2. Dental Chews & Toys: Look for products approved by the Veterinary Oral Health Council (VOHC).
3. Professional Cleanings: Your vet can perform cleanings under anesthesia to remove tartar and check for problems below the gumline.

Need Immediate Advice? Consider a Vet Chat Service

If you're worried and can't get to your vet right away, a telehealth service can provide guidance. Services like Waggle Vet Chat offer 24/7 access to licensed veterinarians who can help you assess the situation and determine the urgency. It's a great resource for non-emergency questions while you arrange an in-person visit.

What to Do Now

If your dog has lost a tooth, schedule a vet appointment immediately. This is not a "wait and see" problem. A lost tooth means there is advanced disease, and other teeth are likely painful and at risk. Your vet can provide a proper diagnosis and treatment plan to relieve your dog's pain.
