Just something to watch for - if your child gets recurrent ear infections or complains regularly of pain in the ear, you may want to check for TMJ (Temporo-Mandibular Joint) trouble.
This is the joint where the jaw joins the temporal bone of the skull, immediately in front of the ear on each side of your head. A small disc of cartilage separates the bones, each time you chew, talk, swallow, yawn or make faces you move it. You can also feel the joint motion in your ear canal. When everything is not not quite fitted, ie: the teeth (bite) are not perfectly aligned, the pressure to this area may not be distributed evenly and pain in or near the ear or both ears may develop. Your child may appear to have an ear infection without many of the associated symptoms. Look for ear pain, sore jaw muscles, temple or cheek pain, jaw popping, clicking or grinding, locking of the jaw, difficulty in opening the mouth fully, ringing in the ears, or frequent head/neck aches.

If you think your child may be suffering from TMJD, mention it to your doctor. The good news is the symptoms can often be alleviated and prevented by avoiding chewing gum, chewing ice, taking large bites, overly extending the jaw (as in yawning or making faces - my daughter does this a lot - silly girl), clenching or tensing the jaw and applying moist heat to the jaw when pain does occur. (Many drugstores sell micowavable heat pads that work really well, or microwaving a damp handtowel works too, just be careful not to make it too hot.)

Your doctor, dentist, or specialist (otolaryngologist) may have more long term solutions if the problem persits and may recommend braces or other alignment, relaxation techniques, muscle relaxants or anti-inflammatory drugs. Check with your medical insurance as well, as many companies cover some of the cost of braces if the need is related to TMJD.
