Answer
A: Do you NEED or do you WANT?
NEED: Are these stains on your teeth becoming hard to remove with your daily brushing? Are your gums bleeding again? Are you having bad breath again? That’s when you NEED to have a Professional Teeth Cleaning.
WANT: Do you WANT to have a Professional Teeth Cleaning before all the above happens? That would be a wiser choice. Visit your dentist 2 to 3 times a year for a Professional Teeth Cleaning and a general oral check up.
