Dog’s mouth is prone to infections that cause bad breath and odor. The most common infection is the periodontal disease which affects 75% of dogs of 2 years of age and above. This foul smell results when bacteria cause inflammation in the gums present around the teeth. When teeth are not brushed, these bacteria along with food particles can deposit on the teeth. When left untreated, this continues to grow until this inflammation leads to periodontal disease. This can cause permanent damage to the gums. This irreparable damage can lead to deeper infection, pain, and tooth loss eventually. Periodontal therapy aims at restoring oral health by regular teeth brushing and regular dental checkups. Brushing teeth for dogs is just as important as for humans and ensures a healthy life.
