When Cracked Molars, Headaches and Dizziness Share the Same Root Cause
For about ten years, Mitzi's molars kept fracturing and needing crowns. She assumed it was age. Her dentist had mentioned grinding at visits along the way, but she wasn't ready to believe it.
It took a replaced crown and a more direct conversation about grinding before the pieces came together. Around the same time, Mitzi was dealing with mild vertigo, neck pain and headaches that woke her in the middle of the night, and she wasn't sleeping well. Even as a nurse researching her own symptoms, she hadn't connected them to her teeth or jaw.
That's a common pattern. Clenching and grinding — often during sleep — can overload the jaw muscles and joints, and the strain can show up well beyond the mouth: as fractured teeth and worn crowns, as tooth sensitivity, as headaches, or as neck and shoulder tension. It's one of the reasons a jaw-focused evaluation can be worth considering when several of these symptoms show up together.
Mitzi was cautious and honestly didn't expect a splint to help. But after years as Dr. Fernandez's patient, she trusted his judgment and decided to try one. She says she slept well from the first night, the nighttime headaches faded within about two weeks, and the dizziness, jaw pain and tooth sensitivity went away too. Her one complaint: she wakes up with a dry mouth, which goes away once the splint is out. Everyone's experience is different, but an oral appliance like this is usually where we start: a conservative, reversible way to take strain off the teeth and jaw before anything more involved is considered.
Mitzi's goal is to keep her natural teeth for life. She points to the bite marks on her splint as proof of how much force it is absorbing instead of her teeth, and says the biggest difference is her quality of life: no more waking up in the middle of the night with a headache, jaw pain or neck pain.
