Causes of secondary headache

There are different types of splints. Some fit over the top of the teeth, some on the bottom. They may be designed to keep your jaw in a more relaxed position, inhibit clenching, or provide some other function. If one type doesn't work, another may.

For example, a new type of splint is called the NTI-tss. It fits over just a couple of top, front teeth. The idea is to keep all of your back teeth completely separated, under the theory that most clenching is done by these back teeth. With the NTI splint, the only contact is between the tiny splint and one bottom front tooth.

MORE AGGRESSIVE TREATMENT

Be cautious about any non-reversible treatment method that permanently alters your bite. However, if a mouth guard doesn't work, your dentist may recommend orthodontics to help re-align your teeth.

Reconstructive surgery of the jaw is rarely required. In fact, studies have shown that the results are often worse than before surgery.

Muscle relaxant medications may help. Nonsteroidal anti-inflammatory medications (NSAIDS) help reduce inflammation in the jaw stemming from arthritis or other causes of inflammation.

For additional information, two excellent books are Taking Control of TMJ by Robert Uppgaard and The Trigger Point Therapy Workbook by Clair Davies.

Most cases can be successfully treated, although initially it may be difficult to diagnose the problem and find an effective solution. Some cases of pain go away on their own without treatment. TMJ-related pain tends to be cyclical and may return again in the future. If the cause is nighttime clenching, treatment can be particularly tricky because it is a sleeping behavior that is hard to control.

Mouth splints are a common treatment approach for teeth grinding. While some splints may silence the grinding by providing a flat, even surface, their effectiveness at reducing pain or stopping clenching is more controversial. Splints may be effective in the short-term but could become less effective over time. Splints can also cause changes in your bite.
