Lactobacillus Acidophilus Cavities

Lactobacillus acidophilus is a form of bacteria that causes cavities to form in the mouths of humans as well as dogs. While most humans know the benefits of good oral hygiene to prevent tooth decay, few dog owners practice good oral hygiene on their dogs. Yet the same bacteria that causes cavities in human teeth also causes cavities in dogs’ teeth. For this reason, dogs require dental care, too.

How Cavities Form

Plaque forms when lactobacillus acidophilus bacteria join together with proteins from food debris in the mouth. The bacteria essentially eat food left in the dog’s mouth between his teeth after he eats. Once the bacteria finish eating, they excrete acid, which can erode the calcium on the tooth’s surface, creating a groove. When bacteria get inside the groove, the tooth starts to decay and periodontal disease (gum disease) sets in. Periodontal disease results when gums around the teeth become inflamed and tender. As the disease progresses and decay destroys the tooth, the bone supporting the tooth also begins to weaken, which could cause the tooth to die and fall out.

Signs of Periodontal Disease (Gum Disease)

A dog affected by excess lactobacillus acidophilus bacteria causing periodontal diseasehas bad breath, changeable eating habits, swollen or bleeding gums and incessant drooling.

Contributing Factors

Although all dog breeds are susceptible to cavities from a build-up of lactobacillus acidophilus bacteria, smaller dog breeds are more prone than large ones. In addition, as dogs age, they become more likely to develop plaque, causing tooth decay in their mouths, especially when they’re not on a good oral care routine.

Treatment

You should clean a dog’s teeth every day after meals. Daily brushing prevents lactobacillus acidophilus bacteria from collecting on the dog’s teeth and removes tarter buildup. Most pet stores sell specially formulated toothpastes and brushes for dogs. A veterinarian can also perform an annual dental exam and recommend an at-home care regimen specific to the dog’s needs.

Prevention/Solution

You should feed your dog a diet low in sugar, as sugar encourages the presence of lactobacillus acidophilus bacteria and leads to plaque buildup. Look for a brand of dog food with the Veterinary Oral Health Council (VOHC) seal of acceptance. VOHC approves acceptable dog food brands that promote oral health in dogs and other household pets.
