Lesson Content

Personal and Environmental Health

Structure of the Tooth

The tooth is made up of the following parts:

Enamel – The hard, outer covering of the tooth.
Dentin – The layer beneath the enamel, which is softer.
Pulp – The inner part of the tooth containing nerves and blood vessels.
Cementum – A layer that covers the root of the tooth.
Root – The part of the tooth that anchors it to the jawbone.
Crown – The visible part of the tooth above the gum line.
Neck – The part of the tooth between the crown and the root.
Periodontal Ligament – Tissue that helps hold the tooth in place.

Dental Problems

Common dental problems include:

Tooth Decay (Cavities) – Damage to the tooth enamel caused by bacteria.
Gum Disease (Gingivitis) – Inflammation of the gums.
Bad Breath (Halitosis) – Unpleasant odor from the mouth.
Tooth Sensitivity – Pain or discomfort when teeth are exposed to hot, cold, or sweet substances.
Toothache – Pain in or around a tooth.
Impacted Tooth – A tooth that is blocked from erupting fully.
Tooth Abscess – A pocket of pus caused by a bacterial infection.
Teeth Grinding (Bruxism) – Clenching or grinding teeth, often during sleep.

Prevention

Preventive measures for dental problems include:

Brushing teeth at least twice a day with fluoride toothpaste.
Flossing daily to remove plaque and food particles.
Regular dental check-ups and cleanings.
Eating a balanced diet low in sugar.
Avoiding tobacco products.
Using mouthwash to kill bacteria.
drinking plenty of water to keep the mouth hydrated.
Replacing your toothbrush every three months.
