Understanding pet dental plaque in dogs and cats
Pet dental plaque in dogs and cats is one of the most common but overlooked pet health concerns. Veterinary studies suggest that around 80% of dogs and 85% of cats over the age of three show signs of active dental disease.
However, plaque, tartar and gum inflammation can develop gradually, often going unnoticed until bad breath, red gums or reluctance to eat appear.
Understanding how plaque and tartar build-up forms in dogs and cats forms is the first step in supporting better oral health and preventing more serious dental problems over time.
Maintaining good dental hygiene is therefore an important part of everyday pet care. Alongside brushing and regular veterinary checks, new approaches are exploring how microbial balance in the mouth influences oral health. There is growing interest in approaches such as probiotic pet dental plaque and tartar remover care.
In this article we explain:
- how plaque and tartar form in dogs, cats and other animals
- why the oral microbiome matters for pet health
- how probiotic dental care can support oral hygiene
- a real-life case example showing improvements in one dog’s dental health
While this article focuses mainly on dogs and cats, LUCAA+ Probiotic Pet Dental Care can also be used for other animals including rabbits and horses.
Quick Answer: Can probiotics reduce pet dental plaque?
Probiotic dental spray for pets introduces beneficial microbes ('good' bacteria or probiotics) directly onto the teeth and gums. These beneficial microbes support a balanced oral environment by limiting the growth of less desirable bacteria and breaking down food residues that contribute to plaque build-up. With regular use, this helps reduce pet dental plaque and supports cleaner teeth as part of an everyday dental care routine.
Why managing pet dental plaque in dogs is important
Plaque dental plaque and tartar build-up are the leading causes of dental problems in dogs and cats.
Adult cats have 30 teeth, while adult dogs typically have 42 teeth. Smaller dog breeds are often more prone to tartar formation, and some pedigree cats are also predisposed to dental disease.
Without regular dental care, plaque can accumulate along the gumline and gradually lead to inflammation and infection.
Common warning signs include:
- persistent bad breath
- red, lightly bleeding or swollen gums
- bleeding from the gums
- reluctance to chew food
- reduced appetite
- visible plaque or tartar on the teeth - teeth may look yellow
- excessive drooling
If left unmanaged, plaque and tartar build-up can progress to periodontal disease - gingivitis and periodontitis - which may cause pain and tooth loss.
Over time, these symptoms of gum disease can also cause reluctance to eat and subdued behaviour. Without intervention they can progress to more serious health conditions.
Using a pet tartar remover as part of a regular dental care routine can help manage this build-up over time.
What is dental plaque in dogs?
Pet dental plaque is a sticky, off-white layer that forms on the surface of teeth shortly after eating.
It develops when food residues mix with saliva and bacteria in the mouth. This creates an environment where microbial communities begin to build on the tooth surface.
Plaque deposits promote the growth of harmful bacteria. If plaque penetrates under their gums, it causes inflammation, bad breath and bleeding (gingivitis). Unchecked, this can lead to deeper inflammation, abscesses, decay and tooth loss (periodontal disease).
If pet dental plaque is not removed regularly for dogs and cats it can irritate the gums and lead to inflammation known as gingivitis. Overtime, the plaque starts to react with mineral salts (calcium phosphate) in saliva, and hardens to form a harder deposit known as tartar.
Because this process starts within 24 hours of eating, managing pet dental plaque in dogs as part of a daily routine is so important for long-term oral health and to prevent the formation of tartar.
What is dental tartar?
Tartar (also called calculus) forms when plaque mineralises and hardens on the surface of teeth.
Tartar is not just a cosmetic problem; it is a painful condition that gradually causes irreversible damage to the soft tissue and gums. It presents as a yellow-brown layer of discolouration.
Over time, tartar build-up can increase inflammation until the teeth loosen. It can:
- irritate the gums
- worsen inflammation beneath the gums
- expose sensitive tooth roots
- lead to the loss of affected teeth
Worse still, if untreated, the infection can spread to the rest of the body and cause heart, liver and kidney problems.
Unlike plaque, tartar cannot always be removed through brushing alone. Veterinary dental procedures such as ultrasonic scaling are sometimes required to remove these hardened deposits.
Although tartar can be successfully removed by ultrasonic descaling, this is usually only a temporary measure. It can be quite expensive and usually needs to be repeated on a regular basis. This is because a fine layer of plaque is re-deposited back on the teeth straight after the first meal. Without regular removal the plaque soon turns to tartar and the whole process starts again.
Why is good dental hygiene necessary for pets?
Why the oral microbiome matters
The mouth is the portal to your pet's body - and a healthy mouth is linked to good health generally - for animals and humans. It contains a complex microbial ecosystem known as the oral microbiome.
This community includes hundreds of species of bacteria and other microorganisms living on the teeth, gums and tongue. The key is to maintain a healthy balance of bacteria (‘good’ and ‘bad’) and other microorganisms found naturally in the mouth.
When microbial communities are balanced, they coexist without causing problems. A diverse, healthy and dynamic microbiome supports good health, well-being and immunity. This is one of the most important factors in pet dental care.
However, when certain unwanted bacteria begin to dominate, the balance of the oral microbiome can shift. An imbalanced microflora in the mouth produces an unpleasant smell, so bad breath can be an early warning sign of gum inflammation.
Researchers are increasingly understanding how microbial balance in the mouth can influence both oral and wider health. The oral microbiome plays a crucial role in both oral and systemic health. A healthy and balanced oral microbiome fosters good general health; but problems occur when the oral microbiome is out of balance.
The formation of dental plaque can involve around 400 different species of bacteria. When bacterial strains linked to dental and other diseases take precedence in the mouth this affects the equilibrium of the whole body.
Signs of poor dental health in animals
It’s therefore essential to take action if your pet has bad breath, red or lightly bleeding gums, yellowish plaque and/or a thick layer of tartar on their teeth. Without intervention these symptoms of gum disease can progress to more serious health conditions:
- Chronic bad breath
- Red, swollen, bleeding gums
- Pain when chewing
- Loss of appetite
- Subdued behaviour
- Visible plaque or tartar (discoloured, brown or yellowish teeth)
- Panting
- Excessive saliva

Serious illnesses caused by canine dental disease
Maintaining a balanced oral microbiome can help to protect animals from dental disease and its links to more serious illness such as:
- Poor appetite
- Heart valve infection
- Liver infection
- Blood infection (sepsis)
- Bone infection (osteomyelitis)

Real example: supporting pet oral hygiene with spray-on probiotics
Pet plaque remover spray in action
This case example shows how supporting pet dental plaque in dogs through a consistent routine can improve oral hygiene over time.
The following case example was shared by a Provilan distributor and illustrates how probiotic dental care was used alongside basic tooth cleaning.
The situation
Luca, a four-year-old Italian Greyhound, had developed:
- noticeable bad breath
- visible tartar deposits
- sore, inflamed gums
Luca had not had an ultrasonic scaling procedure to remove the tartar.
The approach
Luca’s owner introduced a simple daily dental care routine.
Firstly, she gently brushed Luca’s teeth once per day using a pet toothbrush (without toothpaste). She cleaned his teeth from the back towards the front, both the upper and lower row.
Secondly, she applied LUCAA+ Probiotic Pet Dental Spray once or twice daily for three weeks, spraying directly onto his teeth and gums.
If brushing is not tolerated, the product can also be applied using gauze or a soft cloth wrapped around your finger, or with a toothbrush or pipette.
Observed changes over three weeks
After one week
- gum inflammation appeared reduced
- yellow plaque deposits began to lessen
- bad breath improved noticeably
After two weeks
- plaque deposits had reduced significantly
- gum tissue appeared healthier and less inflamed
- breath odour had disappeared
- parts of the hardened tartar began to peel off
After three weeks
- plaque and tartar deposits had reduced substantially
- the yellow coating from the surface of the teeth had disappeared
- gums appeared healthy and not red
- oral hygiene had improved overall
- in this case, there was no need to remove the tartar using a procedure such as ultrasound
This natural pet plaque remover spray supported Luca’s oral microbiome and gum health, and significantly reduced his plaque, tartar and bad breath. It also gave him a lovely white smile. (Note: this is an extra cosmetic bonus; it does not always happen depending on the natural colour of the teeth).
Note: Individual results can vary depending on the severity of dental disease and the existing condition of the teeth.
Supporting the oral microbiome
Probiotic dental spray works by introducing beneficial microbes - 'good' bacteria - that support microbial balance within the mouth.
These microbes help by:
- cleaning teeth, tooth sockets and gums at a microbial level
- inhibiting the growth of harmful bacteria
- breaking down food deposits that contribute to bad breath and plaque formation
- helping to restore healthy microflora balance in the mouth and maintain a healthier oral environment
LUCAA+ Probiotic Pet Dental Care contains plant-derived probiotic strains designed for topical use in the mouth.
The formula is:
- PETA certified as cruelty-free
- vegan
- free from harsh chemicals
- vet approved and scientifically proven
- suitable for dogs, cats, rabbits, guinea pigs and hamsters, horses and other large and small animals
Key Takeaways
- Dental disease affects a large proportion of adult dogs and cats
- Plaque and tartar build up can lead to gum inflammation and tooth loss
- The oral microbiome can play an important role in dental and general health
- Probiotic dental care supports healthy microbial balance in the mouth
- Consistent dental care routines is key to maintaining oral hygiene
How to manage pet dental plaque in dogs at home
When selecting a pet tartar remover, it’s helpful to look beyond short-term results and consider how a product supports your pet’s overall oral environment over time. Different approaches work in different ways, and understanding these can help you choose a routine that suits your pet.
1. Gentle vs harsher approaches
Some pet tartar removers focus on breaking down or removing deposits quickly, often through abrasive or chemical-based action. While these may provide visible results, they may not always be suitable for regular, long-term use in sensitive mouths.
Gentler approaches, including microbiome-friendly formulations, are designed to support everyday dental hygiene without disrupting the natural balance of the mouth. These can be more suitable for ongoing care, particularly for pets prone to sensitivity.
2. Supporting the oral microbiome
The mouth contains a complex community of microorganisms known as the oral microbiome. Maintaining balance within this environment is increasingly recognised as an important part of dental health.
Rather than aiming to remove all bacteria, some pet tartar remover approaches focus on supporting beneficial microbes. This helps create conditions that are less favourable for the build-up of plaque and tartar over time, while supporting a more stable oral environment.
3. Ease of use and routine
Consistency is one of the most important factors in maintaining pet dental hygiene. A pet tartar remover that is easy to apply is more likely to be used regularly, which can make a meaningful difference over time.
Spray-based formats, for example, can be applied directly to the teeth and gums and may be easier for pets that do not tolerate brushing. For others, combining different methods - such as brushing alongside a spray - may form part of a balanced routine.
4. Suitability for different animals
Not all dental products are suitable for every pet. Consider:
- species (dogs, cats, rabbits, horses)
- size and breed
- age and existing dental condition
Choosing a pet tartar remover that is suitable for your pet’s specific needs helps ensure it can be used safely and effectively as part of their routine.
5. Long-term approach to dental care
Pet dental hygiene is not a one-off treatment but an ongoing process. While professional cleaning may sometimes be necessary, everyday care plays an important role in maintaining oral health between veterinary visits.
A consistent routine using an appropriate pet tartar remover, alongside regular checks, can help support cleaner teeth, fresher breath and overall oral comfort over time.

Important veterinary advice
If your pet shows signs of severe dental disease, persistent pain, or difficulty eating, always seek advice from a veterinarian.
Professional cleaning or veterinary treatment may sometimes be necessary before introducing ongoing dental care routines.
Although Luca did not have any ultrasound or de-scaling, older animals with severe build-up may require tartar removal by a vet first. In this case, use LUCAA+ Dental spray for proactive maintenance afterwards.
