How is teeth grinding treated?

Teeth grinding (bruxism) is usually managed rather than cured: a custom night guard protects the teeth, bite problems are measured and corrected, and stress, sleep and jaw-muscle habits are addressed. At Gangnam One Day Dental Clinic the bite is analysed with T-Scan Novus, which records the timing and force of each tooth contact, so adjustments are based on measurements rather than guesswork.

Signs you may be grinding or clenching

Most grinding happens during sleep, so many people only find out when a partner hears it or a dentist sees the wear. Clenching during the day, often while concentrating, is just as common and can be completely silent.

Over time, grinding flattens and chips teeth, cracks fillings and crowns, and overloads the jaw muscles and joints. It is a common hidden cause of sensitive teeth and of implant or crown failures.

  • Flat, shiny or chipped biting edges
  • Jaw tightness or pain on waking
  • Morning headaches around the temples
  • Clicking, popping or locking of the jaw joint
  • Cracked teeth or repeatedly broken fillings and crowns
  • Scalloped edges on the tongue or a ridge inside the cheek

Measuring the bite with T-Scan

When teeth meet unevenly, a few teeth take most of the force and the jaw muscles work harder. Paper marks show where teeth touch but not how hard or in what order. T-Scan Novus records each contact digitally, showing force distribution and timing, so the dentist can see which contacts are overloaded.

Chief Director Dr. Kim Jin-hwan focuses on occlusion and TMJ. He is Vice President of the Korean Academy of Stomatognathic Function and Occlusion (2026–2027) and wrote the chapter on controlling the occlusion of implant-supported restorations in the IGI Global Handbook of Research on T-Scan Technology Applications in Dental Medicine. Bite measurements are also used when fitting implants and crowns, so new teeth are not overloaded.

Treatment: protect, balance, reduce

Protect: a custom night guard spreads force and stops tooth-on-tooth wear. See mouth guards for the types and how they compare.

Balance: if T-Scan shows a few teeth taking excess load, small, measured adjustments or restorations can even out the bite. Worn or broken teeth can be rebuilt with bonding, crowns or, where wear is severe, a planned full-mouth reconstruction.

Reduce: jaw stretches, daytime awareness, caffeine and alcohol limits and sleep review help lower muscle activity. If loud snoring or breathing pauses accompany grinding, a sleep assessment may be advised.

Things to know before you decide

  • A night guard protects teeth but does not stop the brain from triggering grinding; symptoms can return if it is not worn.
  • Bite adjustment removes small amounts of enamel and is not reversible, so it is only done when measurements support it.
  • Over-the-counter boil-and-bite guards can fit poorly and, in some people, increase clenching.
  • Jaw-joint pain can have causes outside dentistry; referral may be suggested if findings point elsewhere.
  • Grinding with loud snoring or breathing pauses may need a sleep assessment before a standard guard is made.

FAQ

Teeth Grinding & TMJ: common questions

Can teeth grinding be cured?
Usually it is managed rather than cured, because grinding is driven by the brain during sleep, stress and other factors. A custom night guard, a balanced bite and habit changes typically reduce damage and jaw pain significantly. The aim is to protect teeth and muscles over the long term.
What is T-Scan and why does it matter for grinding?
T-Scan Novus is a digital sensor you bite on. It records which teeth touch first and how hard, showing force distribution in detail. This shows whether uneven contacts are overloading certain teeth or the jaw, so any bite adjustment or new restoration can be based on measurement.
Why does my jaw hurt every morning?
Morning jaw pain is commonly caused by clenching or grinding during sleep, which tires the chewing muscles and loads the jaw joint. It can also be linked to bite problems or sleep-breathing issues. An examination of the muscles, joints and bite helps identify the cause.
How much does teeth grinding treatment cost in Seoul?
It depends on the diagnostics needed, the type of night guard and whether worn or broken teeth need restoring. Gangnam One Day Dental Clinic gives an estimate after reviewing your photos and symptoms on WhatsApp, and confirms it after examination and bite analysis.
Can grinding damage dental implants or veneers?
Yes. Implants have no natural cushioning ligament, and veneers and crowns can chip under heavy force. Grinders who have or plan implants, veneers or crowns are usually advised to wear a night guard, and the bite is checked so new restorations do not take excess load.
Can I get a night guard during a short trip to Seoul?
Often, yes. A night guard typically needs one visit for the examination, bite analysis and scan, and a second visit a few days later for fitting and adjustment. Send your travel dates and photos on WhatsApp first so the visits can be scheduled within your stay.
