Answer:

When you have acidic saliva, your smile will likely suffer from acid erosion, which can ultimately lead to enamel loss, tooth decay, and cavities. On the other hand, studies have shown that an alkaline pH level in your mouth can increase bone density and enamel strength.

Explanation:

pH of saliva effects tooth decay

When we have acidic saliva, our smile will likely suffer from acid erosion, which can ultimately lead to enamel loss, tooth decay, and cavities.

Effects of pH on growth of plants

pH can affect plant growth in several ways:

In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth.

Soil pH may also affect the availability of plant nutrients.

Nutrients are most available to plants in the optimum 5.5 to 7.0 range.

Effects of pH on aquatic animals

If the pH of water is too high or too low, the aquatic organisms living within it will die.

pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹².

The more sensitive a species, the more affected it is by changes in pH.
