What Is Syncope and Why Does it Happen at the Dentist?

Let me paint a picture. Someone sits in the dental chair looking worried. All of a sudden, their face goes pale and their eyes start to roll. You ask if they’re okay—then, just like that, they slump over in the chair. You just saw syncope—a quick loss of being awake.

Syncope is the medical word for fainting. It happens when the brain doesn’t get enough blood for a short time. At the dentist, this is common. In fact, studies say up to 80% of dental emergencies are because of syncope. [^1]

Why here, of all places? Simple. The dentist’s chair puts together things like:

• Anxiety, pain, and fear (Scared of needles? Many are.)
• Long time sitting and sudden standing up
• Not eating, low blood sugar, and some medicines

Your job is to stop this chain before it causes a problem.

Who Is Most at Risk of Fainting?

Not every patient has the same chance. Over my years seeing patients, I’ve seen some clear things.

People at higher risk are:

• Young adults (16-35 years): Lots get worried, especially on their first visit or if they are scared of shots.
• Older people: Age means more medicines (like blood pressure pills), heart problems, and low blood pressure.
• Nervous or scared patients: Fear alone can trigger a faint.
• People who don’t eat breakfast: Low blood sugar is a faint’s best friend.
• Patients with health problems: Diabetes, heart rhythm issues, dehydration, or nerve problems.

Tip: Always check health histories carefully—and listen to patients when they talk about their worries. It could save you trouble later on.

Can You Stop Syncope Before It Starts?

Here’s something I wish everyone learned on day one: Most fainting can be stopped before it happens. It just takes good steps.

Easy Ways to Stop Syncopes

• Ask about fainting, heart problems, diabetes, or medicines.
• Update the medical alert form.

• Ask them to eat and drink before coming in.
• Suggest they get good sleep and try to relax.

• Build trust as soon as they arrive.
• Use a semi-laying position for nervous people.
• Use kind words and explain each step—so they don’t worry.
• Don’t make them wait or see things that might scare them.
• Give shots slowly and gently.
• Don’t let them stand up fast when you’re finished.

Think of prevention as your safety net. The tighter it is, the fewer emergencies you will need to fix.

How Can You Spot the Warning Signs?

Fainting almost always has some warning. If you get good at catching pre-syncope symptoms, you can stop most events early.

What Patients Might Say

• “I feel dizzy.”
• “Everything’s going blurry.”
• “I feel hot (or cold).”
• “My ears are ringing.”

What You Might See

• Pale, sweaty, or clammy face
• Fast or slow heart beat
• Shaky, weak, or wobbly
• Breathing fast or slow

If you notice any of these:

• Pause what you are doing.
• Talk calmly and reassure.
• Get your team to help.
• Move the chair right away (see next part).

Quick action can stop a full-out faint.

What Should You Do When Syncope Happens?

This is the big part—what makes the difference between a calm, smooth fix and total panic. I use “P-A-B-C” to remember:

P – Position

• Lay the patient flat, feet up. (Like the Trendelenburg position.)
• Loosen any tight clothes at the neck or waist.
• Take out dental tools or anything in the mouth.

A – Airway

• Check they can breathe. Look, listen, feel.
• Open airway gently if needed—tilt the head, lift the chin.

B – Breathing

• Watch for breathing. If slow or shallow, give oxygen (2-6 liters/min through nose) if you have it.
• If not breathing, start CPR right away.

C – Circulation

• Feel for a pulse (wrist or neck).
• Check pulse, blood pressure, and oxygen.

Extra Steps

• Use a cold cloth on the forehead.
• You can use ammonia carefully, but it’s not always needed.
• Speak kindly, reassure, and keep things quiet.

When Do You Call Emergency Services?

• No better in 2 minutes.
• No pulse, no breathing, or if you think it’s something else like a heart problem, seizure, or stroke.

Here’s a simple table to help you remember:

Most people come back to normal in 2 minutes or less with proper steps.

What About After the Episode?

Don’t let a quick recovery fool you—fainted patients need care after waking up.

• What happened and when
• What they felt before and after
• Vital signs, steps you took, how long it took to get better

• Shorter visits
• Different sedation if needed
• Might need to see a doctor

Always be careful—it’s better to be safe every time.

How Do You Get Your Team Ready for Syncope?

This is where practice helps—every dental team should train for emergencies the way firefighters practice for fires.

Team Practice Tips

• Hold training sessions for what to do if someone faints.
• Pretend emergencies with all staff—let each person have a role like “pulse checker,” “emergency call,” or “person in charge.”
• Make sure everyone knows how to use the key emergency gear:
• Oxygen tanks
• Blood pressure kits
• Pulse checkers
• AEDs

A ready team can save lives. Don’t guess—know the plan before there’s a real crisis!

Is It Syncope – Or Something More Serious?

Sometimes, fainting can look like other problems. Knowing the difference lets you help fast.

Things That Look Like Fainting

• Low blood sugar: Usually in diabetics who didn’t eat. Look for sweating, odd actions, or confusion. Give sugar if awake.
• Seizures: Shaking, biting the tongue, funny breathing. After, they may be confused.
• Bad allergy: Fast reaction, rash, swelling, can’t breathe. Needs fast epinephrine shot.
• Stroke: Sudden weakness, slurred words, droopy face. Call for help right away.

Knowing the differences can save someone. If you are not sure, get help—help the patient first, worry about the schedule later.

Can Dental Labs Help You Improve Safety?

You may ask, “What do dental labs have to do with this?”

Good question. Modern digital dental labs help keep patients safe. By using custom tools and parts, they make shorter, easier visits—which means less stress and less chance of fainting.

Also, good labs talk clearly with you and often have fewer problems, so you can focus more on comfort.

Conclusion: Be Prepared, Stay Calm, and Keep Patients Safe

When it comes to fainting in the dental office, stopping it before it happens is best. But if someone does faint, having a good plan makes all the difference.

And remember, working with the right crown and bridge lab or digital dental lab means happier patients, faster work, and safer visits.

You’re not just fixing teeth—you’re keeping people safe. Never forget how much good planning, watching closely, and acting fast can do.
