What you’re describing sounds terrible in isolation, but usually these measures are only done if truly needed — at least in Europe?
I passed on the jaw realignment surgery, knowing that the consequences are more bone wear over time and that I’ll never fully recover usage on the left side of my mouth.
None of the dentists/orthos/surgeons involved said I *had* to do it, there is a trade off. Breaking your jaw might weaken it down the line, but bone wear along the tooth line isn’t great either. It’s a tough call.
Grafting is another thing I’ve been postponing, but now the proximity to my roots is getting painful as sensitivity piles up.
Again: this is all optional and full of trade-offs. Sibling comment suggesting you change dentists is not doing a fair assessment of the situation.
People with bad teeth, on average, die younger and have worse diets.
