Hello Lybrate user, well you want to keep your teeth naturally start brushing properly and that too twice daily and for not less than 3 minutes each time. Even after brushing properly it not possible to clean each and every surface of the teeth so here comes the role of dentist
. Once a year go for scaling which is actually cleaning of our teeth surface with the help of ultrasonic instrument. Glizer toothpaste is good for whitening
our teeth but don't use it regularly because most of this whitening tooth paste contains abrasives which will gradually make your teeth sensitive. Use it for 7 to 10 days and switch on to your regular tooth paste. Reduce intake of colored drinks. Hope this helps.
