Myth:  Scaling is not good for teeth.

Fact: Scaling removes tartar and keeps teeth and gums healthy. Scaling and deep cleaning of gums prevent the problem of bad breath and bleeding gums. Thus, scaling is beneficial for teeth and gums. One should get professional cleaning done by a dentist with a proper ultrasonic scaler. Also getting extensive scaling (more than required) done is harmful.

Myth: Only sugar causes cavities.

Fact:  It is one of the most popular myths about dental cavities. Cavities occur when bacteria produce acids in the mouth. The process can begin by any carb that you consume. That includes sugar, fruits, vegetables, rice and bread. To reduce chances of tooth decay, one should not only practice good dental care but also limit the intake of acidic products.

Myth:  Teeth whitening is harmful as it damages enamel.

Fact: Modern technique like Zoom Whitening works by exfoliating stains from one’s teeth to lighten them and bring back their natural colour. It is the simplest and safest procedure as a product is being used by dentists for being devoid of bleaching agents and chemicals.

Myth: Brushing your bleeding gums is bad.

Fact: Brushing is not only good on teeth but also on your gums and tongue. Brushing these areas helps get rid of plaque which is what causes inflammation and eventually gum disease. One should not brush too hard if they have sensitive gums nor use a hard toothbrush on bleeding gums. Use a super soft toothbrush instead.
