Why when we eat sweets and then toothaches

Sweets can cause of toothaches sometimes because of sugar will absorb water from the tooth nerve. The ability of solution to absorb water through a membrane is one example of osmosis, which is very interesting in the mysteries of nature that caused this.

Osmosis is not responsible for causing toothaches, but a process that has very role for the organism. Oxygen through from the lungs into the corpuscle or Carbon dioxide passes from the corpuscle into the lungs by way of osmosis. Plants get food from ground by osmosis.
