Invisalign treatment itself cannot cause shoulder pain. However, it can worsen TMJ (Temporomandibular joint) and that can result in shoulder pain. The temporomandibular joint is a joint connected to numerous oculofacial muscles and allows for sideways and vertical movement. When it is inflamed or injured it can cause pain in many areas, such as the neck, shoulders or lower back. It is also possible to experience shoulder pain if you are clenching and grinding on your aligners. This puts a lot of pressure on your jaw joint, causing the problem.
In case you suffer from TMJ you should speak with your orthodontist to determine whether it makes sense to stop receiving Invisalign treatment and concentrate on identifying the roots of the jaw pain and discomfort. Although Invisalign does not cause TMJ, they may bring about problems your orthodontist was unaware of before the beginning of Invisalign treatment.
Invisalign is one of the many treatment options that dentists recommend to help patients improve their smiles without affecting their daily lives. However, if you have TMJ disorder make sure you inform your dental provider about it.
