Dental Chews

Dental chews are treats made for dogs (and, in a different form, cats) to gnaw on, with the specific aim of keeping their teeth and gums healthier rather than just filling time between meals. As your dog chews, the physical scraping and abrasion helps lift soft plaque off the tooth surface before it has a chance to harden into calculus, which is the tougher, discoloured buildup that brushing alone can no longer shift. Several controlled trials in dogs have found that a daily dental chew measurably reduces gingivitis, plaque and calculus compared with dogs eating the same diet without one, and some chews also cut down on the volatile sulphur compounds that cause bad breath odour. This matters because periodontal disease, the gum and tooth-supporting tissue damage that starts as plaque-driven inflammation, is thought to affect the majority of dogs by their first year of life, and left unchecked it can progress to pain, tooth loss and wider effects on the body.

It helps to know that dental chews are a supplement to care, not a replacement for it. Daily brushing is still considered the most effective thing an owner can do at home, and dental chews tend to work best alongside it rather than instead of it, especially since brushing less often can leave gaps that a chew helps fill in. A three-way comparison of brushing, a daily dental chew and a prescription dental diet found brushing was by far the most effective at controlling plaque on its own, which is a useful reality check if a chew is being used as a full substitute for toothbrushing. It is also worth knowing that chewing mainly cleans the teeth used for grinding, so front teeth and canines get much less benefit from either chews or dental diets.

Not all chews are equal, and the category is a mixed bag: some are minimally processed animal parts, some are heavily processed products like rawhide, and others are plant-based or designed purely as consumable chew aids. Alongside the dental upside, there are real risks to weigh up, including tooth fractures from very hard products, choking or blockage risk, upset stomachs, extra calories, and contamination concerns with some minimally processed items, so supervision and choosing reputable products matters. A chew that has been independently tested and shown to reduce plaque and tartar, rather than one only claiming to, is generally the safer bet.

A few signs worth watching for and mentioning at your next vet visit:

• Bad breath that doesn't improve with home care
• Red, swollen or bleeding gums
• Visible tartar buildup or discoloured teeth
• Reluctance to chew, dropping food, or pawing at the mouth

If you notice any of these, or you are unsure whether a chew is appropriate for your pet's size, chewing style or dental history, a vet visit is the right next step.
