You pet is considered mature adult. Tooth issues may be seen such as the ones you've observed is common. This is where tooth brushing and dental prophylaxis is so important to avoid situations that may result to tooth loss.
At this point of time, however, we suggest to have your pet check with your veterinarian for appropriate dental treatment. Your vet may suggest tooth extractions if necessary.
For the time being,however, we suggest to provide your pet with soft dog food. Examples are dog dry food soaked with water. This may help your dog at least consume a proper diet. Assess too, if tooth brushing is still possible.
