Question

saliva tends to destroy germs in the mouth

Answer 1

• saliva contains the enzyme lysozyme that attacks and perforates the cell walls of certain bacteria, eventually making them burst.
• Saliva serves to disorganize the oral bacteria that can cause decay.

Answer 2

Many bacteria are thus entrapped and swallowed. In addition, saliva contains the enzyme lysozyme that attacks and perforates the cell walls of certain bacteria, eventually making them burst. Then there are antibodies (immunoglobulin A) secreted into saliva that prevent pathogens from settling in the oral cavity.
