Stages and Effects of Tooth Decay

The video explains the stages of tooth decay, starting with bacteria feeding on sugars to produce acids that dissolve the enamel. Once the enamel is compromised, bacteria can access the dentine, leading to further decay. As the decay progresses, bacteria reach the pulp cavity, causing toothache. If untreated, the infection can spread to the jaw, resulting in an abscess. The video emphasizes the importance of early detection and treatment to prevent severe dental issues.

At what stage do we typically start feeling pain due to tooth decay?

• When the pulp cavity is involved

• When the enamel is first affected

• When the jaw is infected

• When the dentine is exposed

What do bacteria feed on to produce acids in the first stage of tooth decay?

• Proteins

• Minerals

• Sugars

• Fats

What happens to the enamel during the first stage of tooth decay?

• It hardens

• It becomes thicker

• It dissolves

• It changes color

What is the dentine described as in the context of tooth decay?

• A bony structure

• A glossy substance

• A liquid

• A soft tissue

How do bacteria progress after reaching the dentine?

• They exit the tooth

• They enter the pulp cavity

• They move to the enamel

• They stop progressing

What is the result of bacteria reaching the pulp cavity?

• Tooth whitening

• Toothache

• Tooth strengthening

• Tooth growth

Which stage of tooth decay involves the nerves?

• Abscess formation

• Pulp cavity involvement

• Dentine decay

• Enamel decay

What is the primary cause of pain in tooth decay?

• Enamel erosion

• Dentine exposure

• Nerve infection

• Jaw infection

What is the term for the infection that can occur in the jaw due to advanced tooth decay?

• Abscess

• Gingivitis

• Cavity

• Plaque

What is the final stage of tooth decay called?

• Enamel erosion

• Dentine exposure

• Pulp cavity involvement

• Abscess formation
