Understanding Why Dogs Have Tooth Decay : Causes, Symptoms, Prevention, and Treatment

Dogs Have Tooth Decay

Dogs have tooth decay, just like humans, and it can lead to significant health issues if not properly addressed. Tooth decay, or dental caries, is caused by the accumulation of bacteria in the mouth, which forms plaque on the teeth. If not removed, plaque can harden into tartar, leading to the breakdown of the tooth structure. This article from Doshared explores the causes, symptoms, prevention, and treatment of tooth decay in dogs, emphasizing the importance of maintaining good dental hygiene for your furry friends.

Why Dogs Have Tooth Decay

Why Dogs Have Tooth Decay

Understanding why dogs have tooth decay starts with recognizing the contributing factors:

  1. Diet: Diet plays a crucial role in the development of tooth decay. High-carbohydrate diets can promote the formation of plaque. When carbohydrates are broken down, they produce sugars that bacteria in the mouth feed on, creating an acidic environment that erodes the enamel on the teeth.
  2. Poor Dental Hygiene: Just as with humans, neglecting dental hygiene can lead to tooth decay. Infrequent brushing or a lack of dental care allows plaque to build up on the teeth. Over time, this plaque hardens into tartar, which can only be removed by professional cleaning.
  3. Genetics: Some dog breeds are more prone to dental issues, including tooth decay. Smaller breeds, in particular, often have crowded teeth, making it easier for plaque and tartar to accumulate.

Symptoms of Tooth Decay in Dogs

Recognizing the signs that dogs have tooth decay can help in seeking timely veterinary care. Some common symptoms include:

  • Bad Breath (Halitosis): Persistent bad breath is often one of the first signs of dental issues. While some degree of odor is normal, particularly foul breath can indicate decay.
  • Discolored Teeth: Teeth that appear brown or yellow are often a sign of plaque and tartar buildup, which can lead to decay.
  • Difficulty Eating or Chewing: Dogs with tooth decay might experience pain while eating, causing them to chew on one side of their mouth, drop food, or avoid hard foods altogether.
  • Drooling or Dropping Food: Excessive drooling and dropping food from the mouth can also indicate oral discomfort or pain caused by tooth decay.
  • Swollen or Bleeding Gums: Inflamed, red, or bleeding gums are signs of periodontal disease, which often accompanies tooth decay.
  • Loose or Missing Teeth: Advanced tooth decay can weaken the structure of the teeth, leading to looseness or even tooth loss.

Prevention of Tooth Decay in Dogs

Prevention of Tooth Decay in Dogs

Prevention is key to ensuring dogs have tooth decay as infrequently as possible. Implementing a few simple practices can greatly reduce the risk of dental problems.

  1. Regular Brushing: Brushing your dog’s teeth regularly is one of the most effective ways to prevent tooth decay. Use a dog-specific toothbrush and toothpaste to avoid harming your pet. Aim to brush their teeth at least a few times a week.
  2. Dental Chews and Toys: Providing dental chews and toys can help reduce plaque and tartar buildup. These products are designed to promote chewing, which mechanically removes plaque from the teeth.
  3. Professional Cleanings: Regular veterinary dental cleanings are essential for maintaining your dog’s oral health. These cleanings allow for the removal of plaque and tartar that cannot be addressed through at-home care alone.
  4. Diet: Feeding a balanced diet and avoiding high-sugar treats can help prevent the conditions that lead to tooth decay. Specially formulated dental diets can also be beneficial in maintaining oral health.

Treatment of Tooth Decay in Dogs

Treatment of Tooth Decay in Dogs

Despite best efforts, some dogs have tooth decay that requires treatment. Veterinary intervention can address and manage dental caries effectively.

  1. Dental Cleaning: Professional dental cleaning is often the first step in treating tooth decay. This procedure involves scaling to remove plaque and tartar and polishing the teeth to prevent future buildup.
  2. Extractions: In severe cases, where the tooth is too damaged to save, extraction may be necessary. Removing the decayed tooth can relieve pain and prevent further infection.
  3. Fillings: In cases where the decay is not too advanced, veterinarians can sometimes fill cavities to prevent further decay. This approach is less invasive than extraction and can preserve the tooth.

The Importance of Regular Veterinary Check-Ups

Regular veterinary check-ups are crucial for early detection and prevention of tooth decay. During these visits, the veterinarian can assess your dog’s oral health, perform professional cleanings, and provide guidance on at-home dental care.


Dogs have tooth decay just like humans, and it can lead to significant health issues if not properly addressed. By understanding the causes, recognizing the symptoms, and implementing preventive measures, you can help ensure your dog’s teeth remain healthy. Regular veterinary check-ups and professional cleanings are essential for maintaining oral health and preventing tooth decay. By taking these steps, you can keep your furry friend happy, healthy, and free from the pain associated with dental issues.

Remember, dogs have tooth decay, but with proper care and attention, you can minimize the risks and ensure your pet enjoys a healthy, vibrant life. Make dental health a priority in your dog’s routine, and you will both reap the rewards of a happier, healthier life together.
