Do I grind my teeth at night?

Most people who grind in their sleep hear about it from someone else: a partner woken by a gritty squeak, or a hygienist pointing at a flattened edge. You can bring more than a hunch to your next appointment. Here is a one-week way to gather it, and what to take with you.

Signs people notice

The American Dental Association’s MouthHealthy site says most people aren’t aware they clench or grind, and that dentists and hygienists are often the first to spot it. When people do notice, the clues tend to turn up at the edges of the day:

• A jaw that feels tight or sore when you wake up, or tired before you’ve finished breakfast.
• A dull headache, or an ache around the ears, first thing in the morning.
• Teeth that twinge with cold water, or edges that look flatter, chipped or cracked.
• A partner who says they heard you. The NHS lists this as one of the reasons to see a dentist.
• During the day, catching your teeth pressed together at a red light or halfway through a difficult email.

None of these proves grinding on its own. MouthHealthy points out that a sore jaw can also come from sinus problems, infections, arthritis, injuries, gum disease or the jaw joint itself. That’s why what you collect this week is for your dentist to weigh. It isn’t a verdict you reach alone.

Night and day are different things

Clenching while you’re awake and grinding in your sleep can feel related, but Cleveland Clinic describes them as two separate conditions. Awake clenching tends to follow what you’re doing: concentrating, driving, bracing for a hard conversation. Sleep grinding happens without you knowing. Keep the two apart in your notes, and don’t assume one explains the other.

A week of your own evidence

Seven nights is long enough to see whether anything repeats and short enough that you’ll actually finish. You need your phone, a charger and about five minutes each morning.

Before the first night

• Put the phone on the nightstand, plugged in, microphone uncovered and facing your side of the bed. Not under the pillow.
• Write down the regular noises in your room: the fan, the fridge through the wall, the cat that turns up at 2am. You will hear them again in the morning, and knowing them in advance makes the listening quicker.

Each morning

• Before you get up, notice your jaw. Loose, or tight? Write one word.
• Play a handful of the night’s strongest sounds and mark only the ones you’re confident about. Anything you’re unsure of can stay unmarked. Three moments you’d swear to are worth more than twenty maybes.
• Add one line of notes about the day before: when you had your last coffee, whether you drank, a deadline, a late night on your phone, anything new. Facts, not theories.

During the day

• Two or three times, whenever you remember (waiting for the kettle, stopped at lights, before a meeting), check where your teeth are. Apart and relaxed, or pressed together?

On day seven

Read the week back. Did the sounds you marked bunch up on certain nights? Do those nights share anything in your notes? Did the clenched check-ins pile up on workdays? Write down what you see and hold it loosely. A week is a small sample, and your dentist is the one who can say what it means.

This is the routine Bruxa is built around. It records the night on your iPhone and lines up the sounds it heard, strongest first, for you to play and mark “Sounded like grinding” or “Not grinding”. Jaw check-ins and a “What changed?” note sit beside each night. Bruxa gives the night no score and counts nothing, and the audio never leaves the phone.

What a recording can’t tell you

• It can miss things. Quiet clenching may make no sound a phone can pick up.
• By sound alone, a phone can’t reliably tell grinding from a fan, traffic, a pet or a partner. Your ears are the filter, and they get it wrong sometimes too.
• A quiet night is not proof that nothing happened.
• It can’t see your teeth. Cleveland Clinic notes that dentists usually go by an examination and your symptoms, and that an overnight sleep study is sometimes used.

What to bring to your appointment

• The signs, with when they happen. “Sore jaw most mornings, gone by lunch” tells a dentist more than “jaw pain”.
• Two or three of the sounds you marked, ready to play. A few seconds each is plenty.
• Your week of notes and jaw check-ins.
• A list of the medicines you take. The NHS says grinding is sometimes linked to medicines for sleep problems, depression or anxiety. Don’t stop or change a medicine on your own; ask whoever prescribed it.
• Your questions, written down before you sit in the chair. For example:
  • Can you see wear on my teeth, and where?
  • Is it worth protecting them with a night guard?
  • Should I raise anything with my doctor, like stress or sleep?
  • What should I keep an eye on before my next visit?

With Bruxa PRO, the Dentist Report gathers the moments you marked “Sounded like grinding”, your jaw check-ins, your notes and the list of nights you recorded into a PDF and a CSV. Nothing the app guessed goes in.

When not to wait for a week

The NHS suggests seeing a dentist if you grind and have tooth damage or sensitive teeth, or pain in your jaw, face or ear; if a partner says you grind in your sleep; or if you’re worried about a child grinding. For things that can sit behind grinding, such as stress, anxiety, smoking or drinking, it suggests talking to a GP, your family doctor.
