Teeth Grinding vs. Clenching
The two are related but not identical, and the difference decides how much damage is being done and how fast.
The top and bottom teeth pressing on each other is called clenching. Now, when this clenching moves side-to-side or forward-backward, it results to teeth grinding or medically called as dental bruxism.

Clenching: pressure without movement
Clenching is static load. The teeth hold against each other, sometimes for long stretches, often during concentration or sleep. Because nothing moves, it is quiet - which is why clenchers are usually the last to know.
The damage is to the muscles and the joint rather than the enamel. Morning jaw tightness and temple headache are the usual first clues.
Grinding: pressure with movement
Grinding adds motion under that same pressure. Now enamel is being worn away, and the joint is being loaded through a range of movement it was never meant to carry under that force.
Grinding is noisier, more likely to be reported by a partner, and visible to a dentist as flattened, chipped or increasingly sensitive teeth.
Why the distinction changes treatment
They are not interchangeable problems. Grinding raises the urgency of protecting the tooth surface before it is lost, while clenching directs attention to muscle load and how the bite closes.
Most patients do some of both, in a mix particular to them. Establishing that mix is part of what a TMJ screening is for.

The self-check takes a minute and shows you which of your symptoms trace back to the jaw joint.
