Answer 10

cementum

Question 11

______ also protects the root from decay and sensitivity.

Answer 11

Cementum

Question 12

______ is the soft, innermost tissue of the tooth that contains nerves, blood vessels, and connective tissue.

Answer 12

Answer 14

dental pulp

Question 15

The ______ helps in immune defense by responding to infections or injuries.

Answer 15

dental pulp

Question 16

______ is the part of the jawbone that supports and holds teeth in place.

Answer 16

Alveolar bone

Question 17

______ forms the sockets that anchor the tooth roots and works with the periodontal ligament to provide stability during chewing and biting.

Answer 17

Alveolar bone

Question 18

The ______ continuously remodels in response to forces from tooth movement, such as orthodontic treatment.

Answer 18

alveolar bone

Question 19

The ______ also plays a crucial role in oral health, as bone loss due to gum disease or tooth loss can lead to structural changes in the jaw.

Answer 19

alveolar bone

Question 20

______ is a soft connective tissue that surrounds the tooth root, attaching it to the alveolar bone.

Answer 20
