great advise riya!!
Just want 2 add 1 more point. I'm actually a dental student and wht ive learnt is that there is ! single step u can take to ensure good health of your teeth.
ENsure that obviously u brush twice a day, if u brush once a day, then ensure that its at night, since thats when our saliva flow is lowest, and therefore bacteria in the mouth are more active as there is less saliva( which conatins enzymes and anti-bacterial properties) to wash away bacteria.
THE MOST IMportant factor, howver is to use fluoridated toothpaste, Look at the back of your toothpaste tube, and your fluoride concentartion should b a minimum of 1000 ppm of Fluoride, most have 1450 ppm ( parts per million), this is the exact way it is quoted on the toothpaste tube -
Once uve brushed with this, spit out the excess toothpaste BUT DO NOT RINSE YOUR MOUTH WITH WATER. By doing so the water washes the fluoride away.
Fluoride is important as it helps to protect the teeth 4rm decay and strenghthens your teeth.
Fluoride can help to reverse the decaying processes in teeth as well, where the decay is not that extensive.
I know it seems weird not to rinse your mouth with water, but trust me it really helps
I didn't know all of this b4 i joined dental school, my dentist never told me about this, but it really is the easiest and best way to take care of your teeth :)
