If you've been asking the question 'how often should I brush my dog's teeth?', you might be surprised to learn that the answer is more frequently than you probably think. Like humans, dogs get plaque on their teeth, which can cause issues when it builds up. For this reason, dog owners should ensure they have the best toothbrush for dogs and make brushing their pup’s teeth part of their normal routine.
From picking out the best toothbrush to learning how to brush a dog’s teeth, getting started is often the hardest part. The frequency at which a dog’s teeth are brushed can have a huge impact on how effective toothbrushing is—keep reading to learn more about how often you should brush your dog’s teeth.
Why should I brush my dog’s teeth?
Dental disease is one of the most common diseases seen by veterinarians. It is estimated that at least two-thirds of dogs have some degree of periodontal disease by the time they reach 3 years of age. Periodontal disease is especially prevalent in small dogs and brachycephalic (i.e., flat-faced) breeds like Pugs and French Bulldogs.
Periodontal disease occurs when plaque, a sticky film containing bacteria, builds up and mineralizes into calculus, also known as tartar. Calculus acts as a surface for bacteria to accumulate and multiply, thus resulting in gingivitis, or inflammation of the gums. This can lead to pockets forming between the gums and affected teeth, loose teeth, and eventually tooth loss. Detecting and treating periodontal disease early can prevent oral pain as well as issues in organs such as the heart, liver, and kidneys if bacteria enter the bloodstream and travel to them.
The American Animal Hospital Association (AAHA) (opens in new tab) recommends that an oral hygiene routine is initiated when a puppy’s adult teeth come in to prevent or delay the development of periodontal disease. Although there are several products on the market to help prevent the buildup of plaque, toothbrushing is the most effective technique. A toothpaste specifically formulated for dogs should always be used, as they are safe to be swallowed unlike human toothpastes, which contain ingredients that can cause tummy upset in dogs or even be toxic, such as xylitol (opens in new tab).
How often should I brush my dog’s teeth?
In an ideal world, a dog’s teeth should be brushed twice a day to keep dog teeth clean and healthy because plaque buildup can occur within hours after a meal. This is not feasible for most owners, however. It typically takes 24-48 hours for plaque to harden into calculus, so toothbrushing is recommended every day or every other day at a minimum—the more frequent, the better!
Toothbrushing should be performed for at least 30 seconds on each side of the mouth, focusing on the gumline and not forgetting the back teeth, which tend to accumulate plaque and calculus the fastest.
Is brushing my dog’s teeth once a week enough?
Because of how quickly plaque mineralizes into calculus, brushing only once a week may not be effective at preventing periodontal disease in dogs. Although a 2021 study published in Animals (opens in new tab) that was conducted on 160 racing Greyhounds found that both daily and weekly toothbrushing significantly reduced calculus buildup, only daily brushing was able to reduce gingivitis, which can be painful and lead to the progression of dental disease. In addition, a study on Beagles published in the Journal of Veterinary Dentistry (opens in new tab) in 2015 found that brushing daily or every other day significantly reduced the severity of gingivitis and the accumulation of plaque and calculus compared to brushing weekly. It is therefore recommended to brush a dog’s teeth at least every other day, if not daily.
If you are unable to brush your dog’s teeth this frequently for whatever reason, the addition of other types of plaque-preventative products can help to keep plaque at bay. These include the best dental chews for dogs, oral gels, wipes, water additives, and veterinary dental diets. The Veterinary Oral Health Council (VOHC) provides a list of products (opens in new tab) that have been scientifically proven to prevent the accumulation of plaque and calculus. You should also consider alternatives to toothbrushing if your dog tries to bite you when you go near them with a toothbrush—your safety comes first.
What time of day should I brush my dog's teeth?
Although you may see the most benefits with brushing your dog’s teeth right after mealtime, it is more important that the timing is consistent from day to day so that toothbrushing can become a part of your dog’s daily routine. Toothbrushing may be easiest when your dog’s energy is low, like after a walk, since this will be less stressful for both you and them, but the time of day is unlikely to make a significant difference in your dog’s oral health as long as toothbrushing is done regularly.
Is it too late to start brushing my dog’s teeth?
It’s never too late to start brushing your dog’s teeth! Training dogs to tolerate toothbrushing tends to be quicker and easier in younger dogs, but toothbrushing is beneficial for dogs of all ages.
That being said, toothbrushing only works against plaque, not calculus once it has formed. The only way to get rid of calculus is by doing a dental cleaning using specialized tools, which must be done under general anesthesia at your vet clinic. In addition, dogs who have moderate to severe gingivitis may find toothbrushing painful, in which case it is best to wait to start brushing until after they have had a dental cleaning.
If your dog shows signs of dental disease such as bad breath, yellow or brown discoloration of the teeth, obvious calculus, red or bleeding gums, loose or missing teeth, excessive drooling, difficulty chewing, dropping food, or a sensitive or painful mouth, they will most likely benefit from having a dental cleaning. Once periodontal disease has progressed to a certain point, it cannot be reversed and teeth may require extraction to make your dog more comfortable. After an oral examination, your vet can get an idea of the extent of your dog’s dental disease and provide answers to any questions you might have around how much does dog cleaning cost if needed.
