If you are unsure, it is best to consult with your healthcare provider before the blood test. **

Yes, dogs' teeth are generally harder than human teeth. This is because dogs are carnivores and their teeth are designed for tearing and crushing bones and tough meat.

There are four types of teeth in the human mouth: incisors, canines, premolars, and molars. Incisors are the front teeth used for cutting and biting food.

Molars are the back teeth used for grinding and crushing food. **

Wisdom teeth, also known as third molars, can lead to crooked teeth by causing overcrowding in the mouth. When wisdom teeth start to erupt, they can push against the surrounding teeth, causing them to shift out of alignment. This can result in crowding, misalignment, and crookedness of the teeth. In some cases, the pressure from wisdom teeth can also cause the front teeth to become crowded or crooked. **
