Teeth Grinding at Night Singapore: Causes, Damage & When to See a Dentist
Quick answer
Teeth grinding (bruxism) at night is caused by stress, sleep disorders, or misaligned bite. In Singapore, dentists recommend a custom night guard ($200–$800) as first-line protection. Untreated, grinding causes significant enamel loss, cracked teeth, and TMJ disorder — making early treatment far more cost-effective than waiting.
How do you know you're grinding your teeth?
Navigating dental costs and subsidies in Singapore is genuinely complicated — the rules are spread across CPF, MOH, and CHAS documents that most patients never read. I've done that reading so you don't have to.
Most people are told by a partner who hears the grinding sounds. Other signs include waking with jaw soreness, temples aching on the sides of the head (from masseter muscle tension), worn flat tooth surfaces visible when you smile in a mirror, chipped or cracked teeth with no obvious cause, and increased tooth sensitivity.
Your dentist can diagnose bruxism by examining tooth wear patterns and checking jaw muscle tenderness. They may photograph tooth surfaces to track progression over time.
Why does grinding happen?
Stress and anxiety is the strongest driver — Singapore's high-pressure work culture makes bruxism a very common complaint among working adults. Sleep quality directly affects bruxism frequency — poor sleep architecture (from screen use, alcohol, or sleep apnea) worsens grinding.
Other contributing factors include: misaligned bite (malocclusion), certain medications (SSRIs, stimulants), caffeine intake, and sleep apnea (untreated sleep apnea is strongly associated with bruxism — treating the apnea often reduces grinding).
What happens if grinding is left untreated?
Over years, bruxism causes: significant enamel loss (irreversible), cracked or fractured teeth requiring crowns or extraction, receding gums from root stress, and TMJ joint damage leading to chronic jaw pain. Restorative treatment for advanced bruxism damage can cost $5,000–$20,000+. A night guard at $300–$600 prevents most of this.
Cost in Singapore
$200–$1,500
Night guards and bruxism treatment are not Medisave-claimable. Prevention is far cheaper than repairing grinding damage (crowns: $800–$2,000 each).
Key takeaways
- Wake with jaw aches or flat teeth? See a dentist — it's likely bruxism
- Stress is the primary driver — stress management helps alongside a night guard
- Sleep apnea is strongly linked to bruxism — worth ruling out if grinding is severe
- Untreated grinding is expensive — prevention costs a fraction of the repair
