With the confidence of experience, he doesn't believe in giving up. As well as treating these patients, he sends them away to manage their own dental care at home with Philips Sonicare products. The Philips AirFloss is designed to make cleaning between the teeth easier and less time-consuming, which in turn means people are more likely to use it, and therefore it helps transform the health of their gums. The dentist knows he can recommend Sonicare products.
