How many permanent teeth does an adult usually have?
Explanation: Most adults have 32 permanent teeth, including wisdom teeth. 28 teeth is the count without wisdom teeth, while 30 and 34 are not standard numbers for adults. Thus, 32 teeth is correct for a full adult set.
Which part of the tooth is the hardest substance in the human body?
Explanation: Enamel is the outer layer of the tooth and is the hardest material found in the human body. Dentin is softer and found beneath enamel, gums are tissue surrounding teeth, and pulp is the innermost, non-hard tissue.
What is the main cause of tooth decay in everyday life?
Explanation: Tooth decay is primarily caused by plaque, which harbors bacteria that consume sugars and produce acids. Chewing gum and soft foods do not directly cause decay, and brushing too often typically isn't a risk factor.
How often should you brush your teeth each day for good oral hygiene?
Explanation: Most dental professionals recommend brushing twice a day to effectively remove plaque and maintain oral health. Once a day is insufficient, three times is acceptable but not required, and every other day is too infrequent.
What dental problem is specifically caused by inflammation of the gums?
Explanation: Gingivitis refers specifically to gum inflammation. Cavities are holes in teeth, tartar is hardened plaque, and sensitivity describes a symptom, not a condition caused by inflammation.
Which vitamin is essential for healthy gums and teeth?
Explanation: Vitamin C helps support gum tissue health and wound healing. Vitamin A and B12 are important for general health, and Vitamin K helps with blood clotting but is not specifically noted for oral health.
What is the main purpose of fluoride in toothpaste?
Explanation: Fluoride helps harden tooth enamel and makes it more resistant to decay. It does not primarily whiten teeth, add flavor, or just freshen breath, although some toothpaste ingredients serve those functions.
Which type of dental specialist primarily treats children?
Explanation: Pediatric dentists focus on the dental care of children and adolescents. Endodontists treat the dental pulp, orthodontists correct tooth alignment, and periodontists specialize in gum health.
What condition is commonly referred to as bad breath?
Explanation: Halitosis is the technical term for chronic bad breath. Bruxism is teeth grinding, malocclusion is misalignment of teeth, and xerostomia refers to dry mouth.
How often is a routine dental check-up typically recommended for adults?
Explanation: Routine dental visits every six months help prevent and identify oral health issues early. While some may need more frequent visits, yearly or biannual check-ups are not generally recommended for most adults.
