By the time most dogs and cats turn three, some degree of dental disease is already present — and it's almost always silent until it's advanced, because pets rarely stop eating even with a mouthful of pain. Dental health isn't cosmetic; untreated gum disease is linked to heart, kidney and liver issues from bacteria entering the bloodstream. The good news is that it's one of the most preventable health issues in pets.

How dental disease actually progresses

Signs your pet's mouth needs attention

• Persistent bad breath — not just "doggy breath," but a sharp, unpleasant smell
• Yellow-brown build-up on teeth, especially near the gumline
• Red, swollen, or bleeding gums
• Pawing at the mouth, dropping food, or chewing on one side
• Loose or visibly broken teeth

Building a home dental routine

Brushing is the single most effective thing you can do, and it doesn't need to be a daily battle if introduced gradually.

• Start with a pet-safe toothpaste (never human toothpaste — it contains xylitol, which is toxic to pets) on your finger before introducing a brush
• Aim for 3–4 times a week rather than perfection every day
• Dental chews and water additives help but don't replace brushing — think of them as a supplement
• Introduce brushing slowly with young pets so it becomes a normal routine, not a stressful one

Why anesthesia is used for professional cleanings

A thorough dental clean includes work below the gumline, where the real disease hides — this can't safely be done on an awake pet. Pre-anesthetic blood work is done first to confirm it's safe, and modern protocols make this a routine, low-risk procedure for the vast majority of pets, including seniors.
