Dental Chews & Sticks

Dental Chews and Sticks for Dogs Explored

As you will know all too well, keeping your dog's mouth healthy is just as important as looking after their coat or their tummy. Here, though, most dogs will show some signs of dental issues by the time they are 3 years old. While brushing is the best way to clean teeth, not every dog is happy to sit still for a toothbrush.

This is where dental chews and sticks can help.

In this guide, we will explain how dental chews work, how to pick the right one for your pet, and how to make them part of your dog’s daily routine as well.

The Impact of Oral Hygiene on Long-Term Canine Health

In the wild, dogs would clean their teeth by chewing on tough materials. Modern dog food, though, is often softer, which means plaque can build up more easily. Plaque, which is a sticky film of Volatile Sulfur Compounds (VSCs) (bacteria) that forms on the teeth after eating, if it isn't removed, it hardens into tartar (or calculus) within a few days.

Then once tartar forms, you cannot simply brush it away; it usually needs a vet to remove it under anaesthetic.

However, if left alone, it can lead to:

Does Your Dog Have Chronic Halitosis (Bad Breath)?

This is often the first sign that something is wrong.

Gingivitis

Red, sore, or bleeding gums.

Periodontal Disease

This affects the tissues supporting the teeth and can be very painful.

Other Health Issues

Bacteria from a dirty mouth can enter the bloodstream and affect the heart, liver, and kidneys.

Impact of dental health on canine heart disease

Chronic oral inflammation allows Gram-negative bacteria and Volatile Sulfur Compounds (VSCs) to enter the bloodstream through inflamed gingival tissue.

This systemic spread can lead to bacterial endocarditis, where bacteria colonise heart valves, as well as potential secondary damage to the liver and kidneys.

Can a dental stick replace professional scaling?

No. While sticks are excellent for daily prophylactic care, they cannot reach the subgingival areas where the most damaging bacteria reside. Once plaque has mineralised into calculus, it requires professional ultrasonic scaling and polishing under veterinary anaesthesia to be safely removed.

Why does my dog's breath still smell after a dental stick?

If halitosis persists, it often indicates that the bacteria are located in periodontal pockets or on the back of the tongue, which chewing may miss. Persistent bad breath is a primary clinical sign of Stage 2 or 3 Periodontal Disease, requiring a veterinary assessment rather than a treat-based solution.

How to clean back molars without a brush?

To target back molars, utilise molar cleaning sticks specifically designed with a "star" or "X" cross-section. These shapes encourage the dog to use their back teeth to "shear" the treat.

Additionally, applying a small amount of dog-safe enzymatic toothpaste into the grooves of a dental toy can help reach the posterior teeth during play.

Mechanical vs Chemical Action, How Do Dental Chews Disrupt Biofilm?

Dental chews are not just tasty dog treats; they are actually designed with a specific job in mind.

As here they work in three main ways:

1. Mechanical Cleaning

The most important part of a dental stick is its texture and shape. Most have ridges, "X" shapes, or hollow centres. As your dog chews, these shapes then scrape against the surface of the teeth and down to the gum line.

To be effective, the dog should ideally be engaged in the mechanical action for at least 2–5 minutes; this duration ensures sufficient friction to disrupt the biofilm.

As here, the mechanical action of the chew targets the gingival sulcus (the pocket between the tooth and gum), where bacterial biofilms originate. By disrupting these colonies, the chew then prevents the maturation of plaque into calculus.

2. Saliva Production

The act of chewing for a long time makes your dog produce more saliva. Saliva then contains natural enzymes that help to kill bacteria and wash away small bits of food.

The longer the chew lasts, the more saliva is produced.

3. Active Ingredients

Many modern chews contain special ingredients to boost oral health. Some use minerals like sodium hexametaphosphate to prevent plaque from turning into tartar, for instance, while others use natural breath fresheners like mint, parsley, or eucalyptus to help with teh dreaded "doggy breath."

This is specifically true with Sodium Hexametaphosphate (SHMP), which acts as a calcium sequestrant. As it binds to the calcium in a dog's saliva, preventing it from being used by bacteria to mineralise plaque into hardened tartar.

VOHC Guidelines, How to Choose Safe Dental Chews by Size and Age?

Not all chews are the same, though, and to get the best results, you need to choose one that fits your dog’s size, age, and chewing style.

For instance, when you are looking at your options when it comes to dental sticks, you should prioritise products with the VOHC (Veterinary Oral Health Council) seal.

This then makes sure that the product has undergone rigorous clinical trials to prove at least a 15% reduction in plaque or tartar.

For instance, here you have:

Size Matters

Always pick a stick that matches your dog’s weight.

Small Dogs

Need thinner sticks that they can get their mouths around. Giving a large stick to a small dog can be too many calories and may be too hard for them to chew safely.

Large Dogs

Need thick, sturdy chews. If a large dog is given a small stick, they might swallow it whole or in large chunks, which is a choking hazard and won't clean their teeth.

Age Considerations

For a dog's age, here you have to factor in, for instance:

Puppies

Most dental sticks are too hard for puppy teeth.

So, please wait until your puppy has their adult teeth (usually around six months old) before starting dental sticks, and always check the packaging for the minimum age.

Seniors

Older dogs may also have sensitive gums or missing teeth.

Here you should look for "senior" versions that are slightly softer but still provide a good clean.

Age-Appropriate Care, When Can Puppies Start Dental Sticks?

Puppies should generally wait until they have erupted their permanent adult dentition, usually around six months of age. Deciduous (baby) teeth are significantly more brittle than adult teeth; introducing hard dental substrates too early can lead to enamel fractures or premature tooth loss. Always verify the minimum age on the product packaging.

How to tell if a chew is too hard for a dog's enamel?

A common veterinary benchmark is the "Thumbnail Test." If the chew is so hard that your thumbnail cannot leave a slight indentation in the surface, it is likely too dense for canine enamel. Items with high dental substrate hardness, such as antlers or certain nylon toys, can cause "slab fractures" in aggressive chewers.

Are antlers safe for dogs with sensitive teeth?

No. Antlers are composed of bone-like calcified tissue with extremely high density. For dogs with sensitive teeth, receding gums, or brittle enamel, the force required to gnaw an antler can cause pain or structural damage. Opt for softer, porous dental sticks that prioritise mechanical abrasion over sheer hardness.

Are olive wood sticks safe for aggressive chewers?

Olive wood is a popular natural alternative because it is infused with olive oil and does not splinter like traditional wood. However, for "power chewers," the wood can still be hard. While generally safer than bones, they should be used under supervision to ensure the dog doesn't break off large, swallowable chunks.

Edible Sticks vs. Natural Chews, Comparative Efficacy and Safety

There are many options available, so you can find what works best for your pet as well.

For instance, here you have:

Daily Dental Sticks

These are designed to be given once a day, and they are usually low in fat and have a porous texture that "scrubs" the teeth.

Natural Chews

While natural items offer great tooth-to-stick contact time, be mindful of dental substrate hardness. Materials like antlers have a high hardness level that may not be tooth enamel safe for aggressive chewers.

Then items like dried bull pizzles, deer antlers, or olive wood sticks are very long-lasting. They provide great mechanical cleaning but can be very hard, so they aren't suitable for dogs with brittle teeth.

Veggie Chews

Great for dogs with meat allergies or sensitive tummies. These often use potato or rice flour and are easy to digest.

Dental Toys

These are made of durable rubber or nylon with grooves. You can sometimes add dog-friendly toothpaste to the grooves for extra cleaning power.

Digestibility Comparison, Are Rawhide-Free Dental Sticks Safer?

Many veterinarians recommend rawhide-free alternatives because they are typically made from highly digestible plant-based starches or collagen. Traditional rawhide can swell in the stomach and poses a risk of gastrointestinal blockage or "bloat" if large pieces are swallowed whole.

Best dental sticks for dogs with beef allergies or IBS

For dogs with protein sensitivities or Irritable Bowel Syndrome (IBS), look for hypoallergenic veggie chews that use potato or rice starch as the primary base. Avoid treats with "animal derivatives" and prioritise grain-free options that use limited ingredients to reduce the risk of a flare-up.

Can dental sticks cause diarrhoea in dogs?

Yes, if introduced too quickly or if the dog has a sensitivity to specific binders or artificial sweeteners like sorbitol. Always introduce a new brand of dental stick gradually. If the chew is too rich or contains high levels of fat, it can lead to osmotic diarrhoea or mild upset in sensitive dogs.

Implementing a Daily Prophylactic Dental Routine for Dogs

You should also ideally make it into a routine.

You can do that, for instance, by:

Timing - Once a Day

Think of it like your own tooth brushing. Give one stick every day at the same time - perhaps after breakfast or when you are cleaning your own teeth.

Watch the Calories

Even though dental sticks are healthy for teeth, they still contain calories.

If your dog is on a diet, remember to reduce their main meal slightly to account for the treat.

Supervise

Always watch your dog while they are enjoying a chew, as this ensures they don't choke on a large piece.

Fresh Water

Chewing can make a dog thirsty, so make sure they have a bowl of fresh water nearby.

Why does my dog swallow dental sticks whole?

Dogs are biologically driven to "gulp" food. If a stick is too small or highly palatable, they may swallow it to prevent others from taking it. This is a major pharyngeal obstruction risk. Always choose a stick sized for a dog larger than yours if they are a known "gulper" to force more chewing time.

Nutritional Management, How to Calculate the '10% Rule' for Dental Treats

Follow the 10% Rule, dental treats and snacks should never exceed 10% of your dog's total Kilocalorie (kcal) requirement. For example, a medium Pedigree Dentastix contains approximately 82 calories. If your dog requires 800 calories a day, that stick represents exactly 10% of their daily allowance, meaning no other treats should be given.

Difference between dental toys and dental treats

Dental treats are edible and provide cleaning through a combination of mechanical action and chemical ingredients (like SHMP). Dental toys are non-edible, made of rubber or nylon, and rely purely on mechanical abrasion. Toys are better for "weight-watching" dogs, while treats provide the added benefit of salivary enzymes and breath-freshening agents.

Frequently Asked Questions

Across our many local pet stores up and down the country, our team often gets asked many questions around dog chews, including, for instance:

Can dental sticks replace brushing?

No. Brushing with dog-safe toothpaste is the "gold standard" of care. However, dental sticks are an excellent second choice for dogs that won't tolerate a brush.

How long does my dog need to chew a dental stick for it to work?

For a dental chew to provide effective mechanical cleaning, your dog should actively chew it for at least 2 to 5 minutes. If your dog consumes the treat too quickly, the ridges do not have enough time to scrape away the plaque biofilm.

If your dog is a "power chewer," consider moving up a size or choosing a denser, longer-lasting variety.

My dog eats the stick in seconds - is it still working?

If your dog finishes a stick too quickly, it isn't spending enough time rubbing against the teeth.

Here, you should try a larger size or a tougher type of chew.

Are rawhide chews safe?

Rawhide is traditional, but some dogs find it hard to digest. If you are worried, there are many "rawhide-free" alternatives made from vegetables or collagen.
