Grinding & Jaw Soreness: Signs You Might Need Night Guards and How We Protect Enamel

Waking with a tight jaw, tender muscles, or a dull temple headache is more than a bad night’s sleep. Many Australians grind or clench their teeth during sleep, a condition called bruxism. Left unchecked, it wears through enamel, chips fillings, and strains the jaw joints. Night guards do not cure grinding, but they place a protective, well-fitted layer between the upper and lower teeth so forces spread evenly and surfaces stay intact. At dentist Rozelle, our goal is simple: protect your enamel, calm overworked muscles, and keep your bite stable.
Signs you may need a night guard
Look for patterns. Do you wake with jaw stiffness that eases by mid-morning? Do your teeth feel “short” or rough at the edges? These are common red flags:
- Morning jaw soreness or tightness, often with limited opening for a few minutes after waking.
- Headaches at the temples or behind the eyes.
- Flat, shiny wear facets on back teeth, or fine vertical “craze lines” on front teeth.
- Chipped edges, broken fillings, or sensitivity to cold due to exposed dentine.
- Gum recession not explained by brushing habits, sometimes with small notches near the gumline.
- Clicking or tenderness in the jaw joints.
When does it move from watch-and-wait to action? If you notice fractures, sharp edges, or persistent morning pain, you are likely past the early phase. A custom guard will help limit further loss while we address triggers.
Why grinding happens
Bruxism has multiple drivers. Stress and disturbed sleep are common. So are high caffeine or alcohol intake late in the day. Some medicines, including certain antidepressants, can raise muscle activity during sleep. A restricted airway can add to the problem, which is why a history of loud snoring or daytime sleepiness deserves screening. You do not cause bruxism by choice, and you cannot simply “decide” to stop while asleep. The plan is to protect teeth now and reduce triggers over time.
How a night guard protects enamel
A night guard is a thin, shaped splint worn on either the upper or lower teeth. It keeps teeth from locking together and spreads forces so enamel, fillings, and implants take less load. It can also guide the jaw into a repeatable position, which often settles muscles.
Do night guards stop grinding? No. They act as a barrier and force-absorber, which is exactly what enamel needs while we stabilise the bite and manage stress and sleep factors.

A chemist boil-and-bite guard can help in the short term. Is it a long-term fix? Not really; fit is variable, thickness uneven, and they can alter your bite if worn for months. A custom guard is made on digital scans, holds its shape, and can be adjusted accurately.
Our approach to protecting enamel
Assessment comes first. We examine teeth, muscles, and jaw joints, and record any cracks or wear. We often take photographs and scan the bite to track changes over time. If snoring or broken sleep are part of the picture, we coordinate with your GP for airway review.
Fabrication follows. We design a guard to suit your wear pattern and bite. Thinner guards work for light grinders; thicker designs resist heavy forces. We polish the surface so it’s easy to keep clean. At the fit appointment, we fine-tune contact points so the jaw can slide smoothly without catching.
Care is simple. Rinse the guard on waking, brush it with a soft toothbrush and liquid soap, then air-dry in its case. Avoid hot water. Clean tablets help weekly. Bring the guard to each check-up so we can refresh the polish and adjust the bite if needed.
Adjunct care matters. Fluoride varnish and remineralising creams can strengthen exposed dentine. Selective bite adjustment can remove high spots that trigger clenching. Some patients benefit from short-term muscle therapy, jaw physiotherapy, or stress-reduction strategies. Where appropriate, we discuss anti-wrinkle injections for masseter overactivity on a case-by-case basis.
When should you see an emergency dentist? If you chip a front tooth, lose a large filling, or the jaw locks open or shut. Prompt care prevents further fracture and pain.
What patients often ask
Will a guard damage my bite? A well-made, reviewed guard supports a stable bite. We avoid designs that shift teeth. Regular checks keep it accurate.
Can I still look after my smile’s appearance? Yes. Cosmetic care sits alongside protection. Treatments like Teeth whitening work safely once the guard is in place and sensitivity is controlled.
Do I wear it forever? Many patients wear a guard most nights for the long term because the benefits are clear. Some reduce use during calm periods. We guide you based on wear markers and symptoms.
