Oral Spring Cleaning at My Local Dentists Northmead | Dentist Northmead The daylight hours are getting longer and the weather is warming up. Spring is finally here, summer is on the way, and for many of us that means spring cleaning time! During spring-cleaning, we clean our houses, desks, offices, and even our cars, but we neglect to think about our teeth. Which is a shame, because the start of spring is the natural time to get your smile and oral health in tiptop condition for the summer that lies ahead.
