Dental disease is the most common health problem in adult dogs and cats, and the reason is simple: almost nobody manages to brush their pet's teeth daily. A spray exists for that gap. It takes about three seconds, needs no cooperation beyond a lifted lip, and can be worked into a daily routine in a way that a toothbrush realistically cannot for most households.

A quick spritz onto the teeth and gums targets the bacteria that produce the odour compounds behind bad breath, which is why the change in smell is usually the first thing owners notice. It can be applied straight into the mouth or sprayed onto a favourite chew if your pet objects to the bottle, and the chewing then spreads it around. Daily use is what makes any product of this type worth having; occasional use does very little.

• 100ml bottle - For dogs and for cats - Applied directly to the teeth and gums, no brushing needed - Can be sprayed onto a chew instead of into the mouth - Intended for daily use

Be realistic about what a spray does. It works on bacteria and breath odour. It does not remove tartar that has already hardened onto a tooth, and nothing in a bottle will: that needs a scale and polish under anaesthetic at your vet. Treat this as maintenance between professional cleans, not a replacement for them. If your pet has a painful mouth, a loose tooth, or breath that has changed suddenly, see a vet rather than reaching for a spray.

Who it's for: Owners of pets who will not tolerate a toothbrush but need something done daily.
