Many people think of snoring as just an annoyance. Many people think of teeth grinding as “a bit of stress.” The reality is that both can have real consequences. Grinding can wear teeth down, crack fillings, and strain the jaw joints. Snoring can be a sign that airflow during sleep isn’t ideal, and in some cases it can be associated with broader sleep breathing concerns.

Dentists don’t replace your GP or sleep physician, but we can often spot the dental and jaw signs early. We can also help with protective strategies for teeth, and we can guide you on when medical assessment is worth pursuing.

Key takeaways

• If sleep breathing concerns are suspected, the right pathway is medical

What is teeth grinding (bruxism)?

Bruxism is clenching or grinding of teeth, often during sleep. Some people also clench during the day without realising it. Clenching can be just as damaging as grinding because it loads teeth for long periods.

You might not know you grind until someone tells you, or until a dentist sees the signs.

Signs you might be grinding

Common clues include:

• flattened or worn tooth edges
• small chips on front teeth
• cracked fillings or crowns that keep failing
• jaw soreness, especially on waking
• headaches or temple soreness in the morning
• teeth feeling “tired” or sensitive
• tight facial muscles

Grinding can also make cracks more likely, especially in teeth with large fillings.

Why do people grind?

There isn’t one cause. Stress can play a role, but so can:

• sleep quality and fragmented sleep
• airway factors
• caffeine and alcohol
• certain medications
• bite factors in some cases

The key is not to blame yourself. The goal is to protect teeth and reduce harm while you work out what’s driving it.

What snoring can mean

Snoring is vibration of soft tissues when airflow is partially obstructed. Some people snore occasionally, especially when congested or after alcohol. Others snore most nights.

Persistent snoring can be associated with poor sleep quality for you and your partner. In some cases, it can be linked with sleep breathing concerns. A dentist can’t diagnose sleep apnoea, but we can help identify red flags and encourage appropriate medical assessment.

Red flags worth discussing with your GP

If you snore and you also have:

• excessive daytime sleepiness
• morning headaches
• witnessed pauses in breathing
• waking up gasping
• high blood pressure
• frequent night waking

it’s worth discussing with your GP. A sleep study may be recommended to assess what’s going on.

How your dentist can help

2)Identify the signs early

Many people don’t realise the damage until teeth become short, flat, or cracked. Early detection helps prevent bigger restorative work later.

2)  Protect teeth with a night guard

A custom night guard can reduce tooth wear and protect restorations by creating a protective barrier between teeth. It doesn’t “cure” grinding, but it can reduce damage.

3)  Manage the consequences

If grinding has caused cracks, sensitivity, or broken restorations, we can stabilise teeth and discuss longer-term protection such as ceramic onlays or crowns when appropriate.

4)  Guide you toward the right next step

If there are signs suggesting sleep breathing concerns, we can encourage medical review. Dentistry and medicine often work together here.

What a night guard feels like (and what to expect)

Most people adapt quickly to a well-fitted guard. It should feel snug, comfortable, and not bulky. If it feels thick or makes you gag, it may not be the right design. Like any dental appliance, it needs follow-up checks to ensure fit remains good.
