Understanding the Effects of Clenching and Grinding Your Teeth
Many of us bite down on our teeth or clench our jaws without even realizing it. This has often been considered a harmless habit. But is continually biting and putting pressure on your teeth actually bad for your oral health?
Defining Bruxism
The medical term for habitual, forceful teeth grinding and jaw clenching is "bruxism." It typically occurs involuntarily during sleep or while awake.
People often assume only major tooth grinding qualifies as bruxism. However, even continually clenching with small forces can lead to problems over time.
What Causes Bruxism?
Doctors aren't entirely sure what causes bruxism, but contributing factors can include:
- Stress and anxiety
- Abnormal bite alignment
- Sleep disorders
- Certain medications
- Smoking, alcohol, caffeine
- Family genetics
Potential Short and Long Term Effects
Bruxism puts a tremendous amount of pressure on the teeth. This can lead to a variety of issues:
Tooth Damage
Continual grinding forces can fracture tooth enamel or even shatter the entire tooth. It also accelerates overall tooth wear and tear.
Headaches and Jaw Pain
All that pressure placed on the temporomandibular joint and surrounding muscles often results in pain and soreness.
Dental Work Complications
The grip force while clenching can dislodge or break dental restorations like fillings, crowns and even dental implants over time.
Tooth Sensitivity
Loss of protective enamel from bruxism leads to tooth sensitivity and nerve pain due to exposure of underlying dentin.
Gum Recession and Bone Loss
Long term grinding causes the gums and bone that support teeth to gradually recede and deteriorate.
Consequences of Leaving Bruxism Unaddressed
It's estimated that around 25% of adults suffer from frequent bruxism. But allowing forceful jaw clenching and teeth grinding to continue unchecked can set you up for myriad issues down the road.
Permanent Tooth Damage
Eventually, extreme bruxism can completely destroy tooth structure necessitating complicated treatments like root canals, crowns or tooth extraction and replacement.
Increased Infection Risk
Tooth enamel normally protects underlying dentin and pulp from bacteria that cause cavities and infections. Loss of enamel allows more bacteria to invade the tooth's sensitive interior.
TMJ Dysfunction
The strain of continual grinding disrupts healthy functioning of TMJ tissues leading to displaced discs, limited mobility, and impaired jaw movement over time.
Digestive Troubles
Jaw muscle tension and misalignment from long term bruxism can make biting and chewing difficult, leading to problems with proper digestion and nutrition.
Protecting Your Oral Health
If you suspect you're grinding or clenching more than normal, don't delay bringing it up with your dentist. There are several things that can be done to protect your teeth.
Address Underlying Causes
Treating issues like chronic stress, sleep disorders or medication side effects may alleviate bruxism triggers. Developing more relaxation techniques can also help.
Dental Treatments
Custom mouthguards, bite splints and nightguards help absorb grinding forces and alter bite alignment to minimize tooth wear.
Monitor and Repair Damage
Regular dental visits allow early detection and repair of existing tooth damage before it gets worse. Things like fillings, crowns and gum grafts help stabilize teeth.
Stay Diligent
Being proactive with at-home care like brushing properly, flossing daily and massaging sore jaw muscles helps mitigate grinding effects long-term.
When to See Your Dentist
Make an appointment with your dentist right away if you experience:
- Tooth fracture, breakage or new onset tooth sensitivity
- Changes in your bite alignment
- Sudden increase in bruxism frequency or force
- Sore, stiff or tender jaw muscles
- Headaches, especially near the temples
Prompt evaluation and management is key to protecting your oral health.
Outlook for People with Bruxism
The bottom line? Any degree of forceful, repetitive biting or clenching applies abnormal pressures to the teeth and should be addressed.
While occasional, mild teeth grinding likely causes little harm, continually overloading teeth can lead to chronic complications over months and years.
Catching bruxism early and taking preventative steps makes the outlook much more promising. So pay attention to your habits and work with your dentist on protecting your smile.
