Nowadays, 8 out of 10 families have pets, and 5 out of 10 have dogs. In fact, the main reason is because dogs are not particularly troublesome to raise, and they are very humane. However, raising a pet will definitely encounter various troubles. What will happen if the dog suddenly loses its teeth? Friends who want to know must read it.

1. Teeth replacement

Generally, dogs will start to lose teeth around 3-4 months old, and it will take about eight months for all deciduous teeth to be replaced with permanent teeth. Therefore, if the dog is younger, it may be losing teeth, which is a normal physiological phenomenon. Because dogs will grind their teeth when their teeth are changing, owners can buy some teething sticks or teething toys for them to consume their energy and prevent them from chewing up furniture or appliances at home.

2. Calcium deficiency

Because the main component of dog teeth is calcium, when dogs are deficient in calcium, their teeth will soften and fall off. In this case, you need to take your dog to the pet hospital for treatment in time and choose appropriate calcium tablets or other treatments.

3. External damage

Dogs are naturally more lively and active. At this time, if they are injured by external force, such as falls, bruises, accidentally eating too hard food, etc., they can easily cause tooth loss. If this is the case, the owner needs to pay attention to whether the dog's teeth have completely fallen out, and whether there is bleeding in the dog's mouth. If the teeth have not completely fallen out or the bleeding cannot be stopped, it is recommended that the owner take the dog to the hospital in time for tooth extraction or hemostasis. If no other tissue is damaged, the tooth will grow back.

4. Oral diseases

If the dog is neither in the tooth replacement period nor has been harmed by external forces, and the daily diet is relatively balanced, but teeth are still falling out, it is likely that the dog has some oral diseases, such as dental calculus, gingivitis and periodontitis, etc., resulting in the teeth not being able to survive firmly in the oral cavity. At this time, it is recommended that the owner take the dog to the pet hospital for examination in time, and then provide symptomatic treatment based on the examination results.

5. Too old

Normally, dogs’ teeth will begin to loosen and fall out when they are about 8 to 10 years old. Therefore, if the dog is already older, then tooth loss at this time is a normal physiological phenomenon. In order to allow the dog to eat normally, the owner needs to give special care during this period, soak the dog's dog food until soft and then feed it. At the same time, it is necessary to feed the dog food rich in calcium and ensure a balanced intake of nutrients.
