Grinding your teeth
Many of us have nervous habits we aren’t even aware of unless someone points them out. These habits are often an unconscious way of releasing stress and anxiety. Sometimes, though, these nervous tics can lead to other health issues. Bruxism (teeth grinding) or jaw clenching are two examples.
In addition to cracked teeth, teeth grinding can cause hypersensitive teeth, aching jaw muscles, headaches, changes in your bite, tooth wear, and even damage to crowns and fillings.
There are two main types of bruxism: one occurs during sleep (nocturnal bruxism) and one during wakefulness (awake bruxism). People who clench or grind their teeth during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnea).
Signs you grind your teeth
If you experience any of the symptoms below, you should make an appointment with your dentist.
Teeth grinding or clenching, which may be loud enough to wake up your sleep partner
Teeth that are flattened, fractured, chipped, or loose
Worn tooth enamel, exposing deeper layers of your tooth
Increased tooth pain or sensitivity
Tired or tight jaw muscles or a locked jaw that won’t open or close completely
Jaw, neck, or face pain or soreness
Pain that feels like an earache, though it’s not a problem with your ear
Dull headache starting in the temples
Damage from chewing on the inside of your cheek
Treatment
Mild bruxism may not require treatment. Your dentist may create a custom-fitted mouthguard to protect your teeth while you sleep. Your dentist may also encourage you to find ways to relieve stress throughout the day and relax your jaw muscles before bed. If medical problems exist, they also need to be treated. Your dentist is the best person to guide you.
If you know or suspect you may be grinding your teeth, make an appointment with your dentist as soon as possible. The sooner you treat the problem, the better your chances of avoiding more costly services, such as repairing or replacing cracked teeth.
