Caring for your pet’s teeth is an important part of maintaining their overall well being. There are several reasons why dental care is more important in this day and age:
*Pets are living longer
Thanks to advances in veterinary medicine and increased awareness of how to look after our pets properly, dogs and cats are now living longer. That's why it is important that their teeth last a long time too. 
*Hereditary traits
Over many years our pets have been carefully bred to achieve the certain distinct characteristics that we know. However, as a result, some of our pets mouths have become quite overcrowded and uneven which can influence the onset of dental disease.
*Hunting reduction
Our canine and feline companions, large and small, had ancestors who resembled and behaved like wolves and lions - catching and eating their food- fur, bones and all - which provided excellent cleaning actions for teeth. While we have excellent diets available now to feed our pets we need to clean their teeth too.
