Impact of Diet on Dog Dental Health: What Every Pet Parent Needs to Know

Does Your Dog’s Diet Impact Their Dental Health?

Yes! A dog’s diet plays a significant role in maintaining oral hygiene and overall health. Poor dental hygiene can lead to plaque accumulation, gum disease, and even systemic infections. While brushing and professional dental cleanings are essential, diet plays a crucial role in supporting dental health between cleanings.

‍

How Important Is My Dog's Dental Hygiene?

Periodontal disease is one of the most common health issues in dogs, affecting over 80% of dogs by the age of three. Poor oral hygiene can lead to serious health problems, including:

• Plaque & Tartar Buildup – Accumulation of bacteria can cause gingivitis and bad breath.
• Tooth Decay & Loss – Severe cases of dental disease can result in tooth extractions.
• Systemic Infections – Bacteria from the mouth can enter the bloodstream and affect major organs, including the heart, liver, and kidneys.

Maintaining good oral hygiene through diet and dental care can significantly reduce the risk of these conditions.

A dog’s oral health is crucial to their overall well-being. Poor dental hygiene can lead to plaque buildup, gum disease, and even systemic infections affecting major organs. Just like humans, dogs require regular dental care, and diet plays a vital role in preventing dental issues.

‍

Brushing & Professional Cleaning Are Key

Daily brushing using pet-safe toothpaste helps reduce plaque and tartar. Additionally, scheduling professional cleanings with your veterinarian ensures thorough removal of hidden bacteria. However, diet also plays a major role in maintaining healthy teeth between cleanings.

‍

How Diet Affects Dental Health

Certain types of pet food promote dental hygiene by naturally cleaning teeth through chewing. Others, however, may contribute to plaque buildup and decay. The right balance of ingredients can prevent common dental issues and keep your dog’s breath fresh.

Comparison of Pet Diets for Dental Health: Dry Kibble vs. Wet Food vs. Raw Food vs. Dehydrated Food

1. Dry Kibble vs. Wet Food

• Dry kibble provides mechanical abrasion, helping to scrape plaque off teeth.
• Some kibble brands are designed specifically for dental health, reducing plaque and calculus buildup.
• Wet food, while easier to eat, sticks to teeth and increases plaque accumulation.

2. Raw Food Diets

• Raw diets provide natural chewing benefits, but uncooked meat may harbor bacteria, increasing the risk of infections.
• Raw bones, if not properly supervised, can pose a risk of choking, gastrointestinal blockages, and sharp fragments that may cause cuts in the digestive tract.
• In addition, excessive chewing on hard bones or meat can lead to premature tooth wear or even tooth fractures.

3. Dehydrated Foods

• These diets retain nutrients while providing some chewing resistance, often making them a better alternative to wet food for dental health.

Ingredients That Support Dog Dental Health

Certain nutrients play a crucial role in maintaining strong teeth, healthy gums, and reducing oral bacteria:

‍

• Zinc – Supports wound healing, reduces plaque formation, and helps control bacterial overgrowth in the mouth.
• Medium-Chain Triglycerides (MCTs) – Have antimicrobial properties that reduce harmful bacterial populations.
• Enzymes- certain enzymes can help break down 
• Omega-3 Fatty Acids – Reduce inflammation and support overall gum health.
• Prebiotics & Probiotics – Help balance oral and gut microbiota, reducing the prevalence of pathogenic bacteria that contribute to dental disease.
• Polyphenols & Natural Antioxidants – Found in foods like cranberries and green tea, these compounds help prevent bacterial adhesion to teeth and reduce inflammation.
• Calcium & Phosphorus – Strengthen enamel and maintain strong tooth structure.
• Enzymes (e.g., Proteases, Amylases, and Glucoamylase) – Help break down food particles and biofilms, reducing plaque formation.
• Lysozyme & Lactoferrin – Natural antimicrobial enzymes that help combat pathogenic bacteria in the mouth.

‍

Carbohydrates and Sugars: The Hidden Danger

Certain foods contribute to plaque buildup and poor oral health:

• High-Carbohydrate Diets – While dogs do not produce salivary amylase to break down carbohydrates in the mouth, starchy foods can still adhere to teeth, providing a substrate for bacterial fermentation and plaque formation.
• High Sugar, Soft or Sticky, Processed Treats – Treats with added sugars and starches stick to teeth and promote plaque accumulation.
• Soft Canned Food – Lacks mechanical cleaning action and can contribute to tartar buildup.

Note: Although high-carbohydrate diets have often been blamed for plaque, research shows that high-protein diets can also contribute to tartar, as many oral bacteria in dogs thrive on protein as well. Therefore, it’s not always clear that carbs are worse than protein for dental health. A balanced diet, combined with regular dental care, is key.

‍

Chewing and Dental Treats: A Snack & a Hygiene Tool

Certain chews and toys can help reduce plaque and tartar buildup, but they should complement, not replace, daily oral care.

‍

• VOHC-Approved Dental Chews – Products approved by the Veterinary Oral Health Council (VOHC) have been scientifically tested to reduce plaque and tartar.
• Raw Bones (Supervised) – Provide natural chewing resistance, but should be used cautiously to avoid dental fractures, choking hazards, and gastrointestinal obstructions.
• Rubber Chew Toys – Stimulate gums and help remove food particles from teeth.

‍

Dental Hygiene Beyond Diet: Brushing & Professional Care

‍

Even with the best diet, regular dental hygiene is essential:

1. Daily Brushing – Use dog-safe toothpaste to remove plaque before it hardens.
2. Routine Professional Cleanings – Vet checkups help detect and address dental issues early.
3. Dental Wipes & Water Additives – Useful for dogs resistant to brushing.
