Primary Teeth:
Primary teeth, also known as baby teeth, are temporary structures that are present from birth to around age 6 or 7.
They are typically made of a softer tissue called dental pulp, which contains blood vessels and nerves that provide nutrients to the developing teeth.
Primary teeth are held in place by muscles in the mouth called the muscles of mastication.
They are replaced by permanent teeth when children reach around age 6 or 7.
Permanent Teeth:
Permanent teeth, also known as adult teeth, are formed completely from hard tissue called enamel.
They are more durable and resistant to damage than primary teeth.
Permanent teeth have an outer layer called dentin that contains nerve endings and blood vessels.
The root portion of a permanent tooth extends deep into the jaw bone, providing stability and support.
They are also less mobile than primary teeth and cannot be easily displaced or knocked out.
Additional Points:
Primary teeth are typically smaller and softer than permanent teeth.
They have a limited number of cusps and ridges, which are small bumps that help with biting and chewing.
Permanent teeth have more cusps and ridges, which are larger bumps that help to grind food.
Primary teeth are not visible when a person smiles, but permanent teeth are usually visible
