The four goals of treating periodontal diseases in dogs and cats are the same as those used to treat people:

• Removing accumulated plaque and tartar
• Battling infection-causing bacteria
• Reducing inflammation, and
• Halting bleeding

Alkaloids, tannins, essential oils, and flavonoids are examples of phytochemicals that have antibacterial, antiviral, antifungal, antioxidative, anti-inflammatory, and immunomodulatory properties. This enhances oral hygiene and prevents periodontitis, gum disease, and tooth decay. 

Further research on canine and feline clinical studies is required for the responsible use of nutraceuticals in periodontal disorders. The table below shows a list of Nutraceuticals or plant extracts that have been researched in this field.
