It depends on the dog - Barney is 10 and has never had a dental. Daisy also 10 has to have a dental soon for a broken tooth and she's going to a dentist not my regular vet since she's high risk. Her exam went well and she has little plaque and no gum recession or periodontal disease. This has been due to alot of home care. Both have eaten only soft home cooked foods with some kibble at times and plenty of crunchy veggies. I don't know why but I've had really good luck with teeth - Teddy is 22 mos and his teeth are also very good with no plaque or stains. Maybe it's the home cooked food.
I'm glad your baby is going to feel better soon
