Many tooth biscuit recipes incorporate ingredients like enzymes, abrasives, or antimicrobial agents that actively reduce plaque and tartar buildup.

Certain tooth biscuits contain L-arginine, an amino acid that has been shown to help neutralize the acidic byproducts of dental bacteria.

Some tooth biscuit brands include green tea extract, which is a natural source of polyphenols with demonstrated antibacterial effects against oral pathogens.

The crunchy, fibrous nature of tooth biscuits can help strengthen a dog's jaw muscles and stimulate the gums, improving overall oral health.

Tooth biscuits formulated with kelp or seaweed derivatives may provide beneficial minerals like calcium and magnesium to support tooth and enamel strength.

Probiotics included in some tooth biscuit recipes can help rebalance the oral microbiome and suppress the growth of harmful bacteria.
