Why is occlusal adjustment generally discouraged as a first-line TMD treatment?

• A. Because it is expensive
• B. Because evidence shows limited efficacy and potential for irreversible changes that may worsen symptoms; guidelines favor reversible, conservative therapies
• C. Because it is always painful
• D. Because it is illegal in some jurisdictions

Answer: (C)

Starting with reversible, conservative strategies is the guiding approach in TMD care because most patients improve without permanently altering the bite, and irreversible changes carry real risks. Occlusal adjustment reshapes the biting surfaces to change how the teeth contact each other, but the evidence for its effectiveness in reducing TMD symptoms is limited and inconsistent. Because the procedure permanently changes tooth structure, it can create new occlusal imbalances or worsen symptoms in some patients, and there’s a concern that benefits are not durable. That’s why guidelines emphasize non-permanent options first, such as patient education and self-care, bite splints to reduce parFunction forces, physical therapy, and appropriate medications when needed. If occlusal adjustment is ever considered, it should be after trying reversible measures and within a careful, well-monitored plan due to the potential for irreversible consequences. Pain, by itself, isn’t the universal reason for avoiding it—many patients don’t experience sustained relief from adjustment, and the bigger issue is the combination of limited supported benefit and the risk of irreversible change.
