Complete Guide to Dog Dental Care: Prevention and Treatment

Dental disease is one of the most common health problems in dogs. Learn how to brush your dog’s teeth, recognize warning signs, and know when professional cleaning is necessary.

Introduction

Dental disease affects most dogs over the age of three.¹ Unlike humans, dogs don’t develop cavities, but they do develop serious gum disease (periodontal disease) that can lead to tooth loss, chronic pain, and even systemic health problems affecting the heart, liver, and kidneys.

The good news: dental disease is largely preventable with proper home care and professional maintenance. This guide walks you through everything you need to know to keep your dog’s teeth and gums healthy throughout their life.

Why Dog Dental Care Matters

Your dog’s oral health affects their overall wellbeing. Untreated dental disease causes chronic pain that may go unnoticed until severe. The bacteria that accumulate in infected gums can enter the bloodstream and damage vital organs. Early treatment prevents these complications and maintains your dog’s quality of life.

Prevention through daily home care is far simpler and less expensive than dealing with advanced dental disease.

Home Dental Care

The foundation of good dental health is what you do at home every day.

Daily Tooth Brushing

The best preventative measure is brushing teeth daily with dog-specific toothpaste.² Regular brushing can significantly delay or even prevent the need for professional cleanings.

Aim for at least 2-3 times per week minimum, but daily is ideal.³ Once your dog gets used to it, many owners find twice-daily brushing (morning and night) becomes a routine part of their day.

Critical: Never use human toothpaste. Human toothpaste contains ingredients like fluoride and xylitol that are toxic to dogs.⁴ Human toothpaste also has a different pH, which can irritate your dog’s mouth. Use only dog-specific toothpaste, which is formulated to be safe if swallowed and often contains enzymatic ingredients that help break down plaque naturally.⁵

How to Brush Your Dog’s Teeth

Most dogs can learn to accept teeth brushing if you introduce it gradually and positively.

Step 1: Get Your Dog Comfortable⁶

Start by getting your dog used to having their mouth touched. Gently lift their top lip and run your finger along the gum line while praising them. Do this for several days until they’re comfortable.

Step 2: Introduce the Toothpaste⁶

Put a small amount of dog-specific toothpaste on your finger and let them lick it. This introduces them to the taste and flavor (which is often appealing, like chicken or liver). Always reward them with praise immediately.

Step 3: Use a Soft-Bristled Toothbrush⁷

Use a soft-bristled toothbrush designed for dogs, or start with a rubber thimble that fits on your finger. Begin by gently brushing just a few teeth in a circular motion. Over multiple short sessions, gradually build up until you can brush all teeth comfortably.

Step 4: Focus on the Gum Line⁶

Plaque accumulates where the tooth meets the gum. Brush using gentle circular motions, focusing on the gum line rather than just the tooth surfaces. Brush the front and back of the teeth.

Step 5: Make It Positive⁶

Always reward your dog immediately after brushing with praise, treats, or play. This creates positive association and makes your dog more willing to cooperate next time.

Tip for adult or senior dogs: Start small and be patient. Introduce brushing gradually, allowing several days of just touching their mouth before adding the toothbrush. Some older dogs never become completely comfortable with brushing, but even occasional brushing is beneficial.

Dental Chews and Diet

Dental chews help mechanically clean teeth by creating friction as your dog chews, which can reduce plaque buildup on tooth surfaces. However, they are not a replacement for brushing.

Diet considerations:

• Crunchy kibble vs. soft food: Crunchy kibble may provide more mechanical cleaning than soft food, though there is limited scientific evidence that diet alone prevents dental disease.
• Raw meaty bones: Some owners use raw meaty bones under supervision for natural cleaning. These carry risks (choking, broken teeth, stomach upset) and should only be used under veterinary guidance.
• Dental additives: Water additives and specialized dental foods can support oral health but are most effective alongside daily brushing.

Bottom line: Dental chews, special diets, and additives support oral health but cannot replace daily brushing or remove tartar that’s already formed.

Signs of Dental Disease

Early detection allows you to prevent advanced disease. Many owners don’t realize their dog has dental problems until significant damage has occurred.

Early Warning Signs

Watch for these early indicators of dental problems:⁸

• Bad breath — Persistent foul-smelling breath is the most common first sign. Healthy dogs should have neutral-smelling breath; “doggy breath” is not normal.
• Visible plaque or tartar — Yellow-brown buildup on teeth, especially along the gum line
• Red or swollen gums — Gums should be pink and firm, not red or puffy
• Reluctance to eat hard food or treats — Your dog may prefer soft food due to pain
• Difficulty picking up food — Dropping food while eating or chewing on one side only
• Excessive drooling — Particularly if drool has a foul odor or contains blood

Advanced Symptoms

If dental disease progresses untreated, you’ll notice more serious symptoms:⁸

• Pawing at the mouth or face — Sign of pain or discomfort
• Loose or missing teeth — Teeth becoming wobbly or falling out
• Bleeding from the mouth — Blood in water bowl, food bowl, or on chew toys
• Facial swelling — Particularly below the eye, indicating tooth root abscess
• Behavioral changes — Withdrawal from play, irritability, or decreased activity
• Weight loss — Caused by difficulty or pain when eating
• Nasal discharge or sneezing — Infection spreading to nasal passages

Stages of Periodontal Disease

Veterinarians classify gum disease into four stages:⁹

Stage 1: Gingivitis (Reversible)⁹

Gums appear red and swollen. Plaque and early tartar are visible above the gum line. This is the only reversible stage. With professional cleaning and improved home care, complete recovery is possible. No permanent damage has occurred.

Stage 2: Early Periodontitis⁹

Infection spreads below the gum line, causing up to 25% attachment loss between teeth and supporting structures. Gum pockets begin forming. Bone loss starts but isn’t visible on X-rays yet. Professional cleaning can halt progression, but damage cannot be reversed.

Stage 3: Moderate Periodontitis⁹

25-50% attachment loss with visible gum recession. Bone loss becomes visible on X-rays. Multiple teeth may be affected.

Stage 4: Advanced Periodontitis⁹

More than 50% attachment loss with severe gum recession and extensive bone destruction. Multiple teeth require extraction. Risk of jaw fracture increases, particularly in small breeds. Bacteria can enter the bloodstream, affecting the heart, liver, and kidneys.

Professional Dental Cleaning

Once tartar has formed on teeth, it cannot be removed by brushing alone. Professional cleaning under anesthesia is necessary.

What Happens During Cleaning

General anesthesia is required for all dental procedures.¹⁰ This allows the veterinarian to clean both above and below the gum line, examine the entire mouth thoroughly, and safely perform any necessary extractions without causing stress or discomfort.

A typical professional cleaning includes:¹¹

• Pre-operative blood tests and IV fluids to ensure safe anesthesia
• Full oral examination of all teeth and gums
• Ultrasonic scaling to remove tartar and plaque above and below the gum line
• Hand scaling of any remaining tartar
• Dental X-rays to examine tooth roots and bone level below the gum line
• Polishing with an abrasive compound to smooth tooth surfaces and discourage future plaque and bacteria adhesion¹¹
• Extraction of damaged or diseased teeth if necessary
• Post-operative pain relief and care

Why anesthesia is necessary: The thick, hardened tartar deposits that accumulate beneath the gum line cannot be safely removed without anesthesia. Professional scaling reaches areas that brushing cannot access, including deep gum pockets and interdental spaces.

Cleaning Frequency

Frequency depends on your individual dog’s predisposition to dental disease. Many veterinarians recommend annual dental checks to monitor your dog’s oral health. Some dogs may need professional cleaning every 1-2 years, while others with severe predisposition may need cleaning annually.

Dogs with good home care (daily brushing) may need professional cleaning less frequently. Dogs with poor home care or genetic predisposition to dental disease may need more frequent professional cleaning.

Cost of Professional Cleaning

Professional dental cleanings typically range from £149 to £500 in the UK, with an average cost of approximately £233-£235.¹² Costs vary based on:

• Anesthesia and monitoring — More expensive for larger or older dogs
• Dental equipment and expertise — Veterinary time, ultrasonic scalers, and X-rays
• Extractions and complications — Removing diseased teeth costs approximately £300-400 per tooth¹²
• Clinic location and type — Urban clinics and veterinary chains tend to be more expensive

This investment in preventative care is significantly less expensive than treating advanced dental disease, tooth extraction, or managing systemic infections that can result from severe periodontal disease.
