Chewing gum disintegrates in your mouth because of the combination of saliva and mechanical action from your teeth and jaw.

Additionally, the constant chewing and movement in your mouth can break down the gum into smaller pieces, making it feel like it is disintegrating. **

Grout is a mixture of cement, sand, and water that is used to fill gaps between tiles. Over time, grout can deteriorate due to exposure to moisture, cleaning chemicals, and general wear and tear. After 30 years, the grout may have absorbed enough moisture and been subjected to enough stress that it begins to break down, resulting in it disintegrating into dust. Additionally, the constant expansion and contraction of the materials due to temperature changes can weaken the grout over time, leading to its eventual breakdown. **
