Tartar and resorption (destruction) of roots

If plaque is not cleaned, it mineralizes and turns into tartar. The smell from the mouth becomes stronger, and on the teeth we see brown or dark gray deposits. The stone gradually begins to cover the entire visible part of the tooth and hit the root under the gum. As a result, the tooth dies, the root is destroyed, the dog smells of rot from the mouth.

समस्या का निदान

To understand the cause of the smell from the mouth of a dog, it is first necessary to examine the oral cavity.

If the animal is young and has no complaints about the general condition, then when examining the oral cavity, you can easily find a problem – plaque, food in the teeth, sores on the gums, a broken tooth. Sometimes you can even fix the cause yourself.

If there are other complaints or a pet older than 6 years, it will be more difficult to figure it out. As a rule, a comprehensive examination of the oral cavity, skin assessment, and palpation of the abdomen are required. Next, you should conduct laboratory studies – a biochemical blood test, evaluate organ function and inflammatory processes and anemia, a clinical blood test, conduct an ultrasound examination of the abdominal cavity, and pass urine tests.

An X-ray study allows you to assess the condition of the jaw and the roots of the teeth, it is performed after an examination by the dentist before the extraction of teeth.

Treatment for bad breath in a dog will depend on the causes of its occurrence.

To get rid of tartar, plaque or rotten teeth, a dentist appointment, oral cavity sanitation and removal of non-viable teeth are required. The procedure is different from what people are used to. In dogs, oral hygiene is carried out only under anesthesia and immediately in a complex manner.

In case of inflammation of the gums, antibiotics are prescribed orally and veterinary dental gels – Orozim and Stomadin – to relieve swelling and pain. The underlying cause of stomatitis and gingivitis is also treated.

In kidney disease, treatment is aimed at lowering the level of creatinine and urea in the blood. Droppers are prescribed, appetite is stimulated and special low-protein foods are recommended, for example, RENAL (RENAL) ROYAL CANIN, Hill’s PRESCRIPTION DIET k / d, PRO PLAN® VETERINARY DIETS NF RENAL FUNCTION and others. The disease will need to be monitored throughout life, regular visits to the doctor.

If the cause is in the gastrointestinal tract (GIT), therapy is directed to the surrendering organ. If the case is in the liver, hepatoprotectors are used (to protect the liver), vitamins, droppers, antibiotics and other symptomatic drugs. If in the stomach – gastroprotectors (anti-ulcer), antiemetic. Not without special diets.

To treat diabetes, you will need, as in humans, to put insulin and regularly measure blood sugar, eat a low glycemic index diet and control weight.

If the cause of the smell is a foreign body, trauma or tumor, the help of a surgeon will be required. He will assess the condition of the tissues in the oral cavity and determine the method of treatment. The tumor is usually removed and chemotherapy is prescribed, the wounds are sutured, foreign bodies are removed.

In addition to the fact that a pet, like a person, experiences a toothache, it is difficult for him to eat, the general condition of the body worsens from malnutrition. Local inflammation of the teeth leads to the development of abscesses, fistulas in the nasal cavity, purulent inflammation of the sinuses.

Teeth fall out more often in small breeds of dogs – toy terriers, Yorkshire terriers, Spitz.

Sometimes even pathological fractures of the jaw occur.

A large amount of tartar can cause inflammation of other organs – the stomach, pancreas, as bacteria from the mouth penetrate through the blood throughout the body.

There are several ways to maintain a healthy mouth – toothpaste and brush, hygienic gels, sprays, water additives, toys and food.

  3. Use oral sprays or rinses daily. Now in pet stores a considerable selection of products of this type.

  4. Offer your dog special toys designed to maintain oral hygiene for play.

  5. Industrial feed is also a good helper in the fight for a snow-white smile. If the croquette and the type of food are chosen correctly, the teeth are cleaned mechanically while eating.

Prevention of bad breath in a dog should be comprehensive.

First of all, it is necessary to comply with the rules of feeding and maintenance. The animal has a number of nutritional features, for example, it naturally tears off pieces and swallows them without chewing. Therefore, when choosing a dry diet, it is important to consider the age and size of the dog. This will allow you not to miscalculate the size of the kibble and prevent plaque by mechanical cleaning.

A natural diet should consist not only of soft foods, but also of hard ones. Adding tough vegetables in a natural diet, such as raw carrots, will also create a mechanical peeling effect. To maintain the balance of nutrients in a natural diet, it is best to seek the advice of a nutritionist. This is important for the prevention of diseases of internal organs.

It is necessary that the puppy be kept in acceptable conditions from a very early age, which will avoid developmental pathologies and many diseases in the future.

The diet should be age appropriate.

The content should be in a warm room, with clean bedding. Treat for worms every 3-4 months and for external parasites every month during the season. Choose the right toys so that the puppy does not get hurt by them or damage the teeth.

It is necessary to control the change of teeth in a puppy. By 10-12 months, all molars should be in one row. If the milk teeth have not fallen out, be sure to have them removed by a veterinary dentist.

Follow the rules of oral hygiene. Do not use sticks, rags, plastic and other unsuitable materials for games, it is better to purchase specialized toys based on the size, age and character of the dog.

Regular check-ups by a veterinarian will allow you to notice diseases in the early stages or even avoid them altogether.
