Explore key lifestyle habits that support dental health, from brushing and flossing to the effects of food, drinks, and regular dental visits. Perfect for learning the basics of oral care.
How many times should you brush your teeth each day to maintain good oral hygiene?
Explanation: Brushing twice a day removes plaque and reduces risk of oral diseases. Brushing only once may leave harmful bacteria, while three or four times could harm enamel and gums if done aggressively.
What is the main cause of tooth cavities developing over time?
Explanation: Cavities are caused by bacteria feeding on sugar and producing acids that damage enamel. Acidic fruits can contribute slightly but are not primary causes, saliva actually protects teeth, and calcium is essential for strong teeth.
How often is it recommended for most people to visit a dentist for a checkup?
Explanation: A dental visit every 6 months helps with early detection and prevention. Annually may miss problems, monthly is unnecessary for most, and two years is too infrequent for preventive care.
Flossing helps remove which material that brushing alone often leaves behind?
Explanation: Flossing removes trapped food and plaque from areas a toothbrush cannot reach. Surface stains are best addressed with brushing, neither gum tissue nor enamel is removed by flossing.
Which type of drink is considered most harmful to healthy teeth?
Explanation: Sugary soft drinks provide both sugar and acid that can erode enamel and promote decay. Water is safe, milk contains calcium, and unsweetened tea lacks damaging sugars.
What is dental plaque primarily made of?
Explanation: Plaque is a sticky biofilm of bacteria on teeth. While saliva can mix with plaque, it's not the main component; fluoride doesn't form plaque and food bits are only part of initial buildup.
Can gum disease have effects beyond the mouth and influence overall health?
Explanation: Yes, gum disease has been linked to systemic health issues like heart disease. 'No' and 'Only in children' are incorrect; the effects can occur in all ages, while 'Sometimes' is vague and less accurate.
Which substance is commonly added to toothpaste and water to protect teeth from decay?
Explanation: Fluoride strengthens enamel and fights decay. Vitamin D and calcium support overall oral health but do not directly prevent decay, and xylitol is a sugar substitute with some benefits but is not the primary protective agent.
Is bleeding from the gums while brushing considered normal?
Explanation: Bleeding gums during brushing can signal gingivitis or gum disease. While brushing too hard may also cause bleeding, it should not be considered normal; 'always' and 'morning only' are inaccurate.
Why is drinking water considered good for your teeth?
Explanation: Water helps clear away food particles and acids that can erode enamel. It typically does not stain teeth, contains little calcium, and does not instantly whiten teeth.
