At Pet Medical clinics we are running a free dental check during the month of August. Why are we doing this? Over 80% of aging pets suffer some sort of dental disease and it becomes more severe with age. Animals with dental disease left untreated will lead to teeth that require extraction due to infection within the gums and jawbone. These teeth can be very painful despite animals hiding mouth pain very well. Bacteria in the mouth can cause damage to the heart, liver and kidneys.
