Premolars, also known as bicuspids, are the teeth located behind the canines. They have a flat surface with two points called cusps, which aid in chewing and grinding food.

9. What happens if a tooth is lost and not replaced?
If a tooth is lost and not replaced, several complications may arise. Adjacent teeth may shift, causing misalignment and bite issues. The jawbone can also deteriorate over time due to lack of stimulation from the missing tooth root.

Maintaining good oral hygiene is crucial for the health of your bottom teeth. Brushing twice daily with a fluoride toothpaste, flossing regularly, and visiting your dentist for check-ups and cleanings are key to preventing dental issues.

Tooth loss in adults can be caused by various factors, including tooth decay, gum disease, trauma, and poor oral hygiene. Other factors such as smoking, certain medical conditions, and genetic predisposition can also contribute to tooth loss.
