Why are the Primary or Baby Teeth so Important?
It is very important to maintain the health of the primary teeth. Neglected cavities can and frequently do lead to problems which affect developing permanent teeth. 
Primary teeth, or baby teeth are important for:
- Proper chewing and eating
- Providing space for the permanent teeth and guiding them into the correct position
- Permitting normal development of the jaw bones and muscles
- Development of speech
- Self esteem and appearance
While the 4 front teeth last until 6-7 years of age, the back teeth (cuspids and molars) are not replaced until age 10-13.
