If your pet is experiencing common dental problems, they may begin to show signs of oral issues such as drooling excessively (and the drool may contain pus or blood), or they may use their paws to physically try to claw at their teeth and faces. They may also yawn excessively, grind their teeth, or stop grooming sufficiently.
Bad breath, swollen gums and pain may all interfere with your pet's eating habits.
