If you snore loudly or feel tired even after a full night of sleep, you are not alone. Millions of people live with undiagnosed sleep apnea, and a simple screening tool can help you find out if you are at risk. I am Dr. Farshid Ariz, DMD, a periodontist at TMJ & Sleep Centre of San Fernando Valley in Brentwood, California. My team and I use the STOP-BANG questionnaire every day to help patients take the first step toward better sleep and better health. Today, I want to walk you through what the STOP-BANG quiz is, how the stop bang score works, and why this quick assessment could change your life for the better.
What Is the STOP-BANG Questionnaire?
The STOP-BANG questionnaire is a validated screening tool developed to identify people who may have obstructive sleep apnea (OSA). It was created by Dr. Frances Chung at the University of Toronto and has since become one of the most widely used sleep apnea screening instruments in the world. The acronym STOP-BANG stands for eight yes-or-no questions that cover key risk factors. Each “yes” answer earns one point, and the total gives you your stop bang score.
Here is what each letter represents:
- S — Snoring: Do you snore loudly, loud enough to be heard through closed doors?
- T — Tired: Do you often feel tired, fatigued, or sleepy during the day?
- O — Observed: Has anyone observed you stop breathing or choking during sleep?
- P — Pressure: Do you have or are you being treated for high blood pressure?
- B — BMI: Is your body mass index greater than 35?
- A — Age: Are you older than 50?
- N — Neck: Is your neck circumference greater than 40 centimeters (about 16 inches)?
- G — Gender: Are you male?
The quiz takes less than two minutes to complete. Yet those two minutes can reveal important information about your sleep health.
How to Interpret Your STOP-BANG Score
Your stop bang score ranges from 0 to 8. The higher the number, the greater your risk for obstructive sleep apnea. Here is a general guide to understanding your result:
- 0–2: Low risk for OSA
- 3–4: Intermediate risk for OSA
- 5–8: High risk for OSA
A study published in the journal Anesthesiology found that a STOP-BANG score of 5 or higher has a sensitivity of 95.2% for detecting moderate-to-severe obstructive sleep apnea (Chung et al., Anesthesiology, 2016). That means the quiz correctly identifies the vast majority of people who truly have the condition. Additionally, research shows that approximately 80% of moderate-to-severe OSA cases remain undiagnosed in the general population, making simple screening tools like the STOP-BANG questionnaire essential for early detection.
If your score places you in the intermediate or high-risk category, the next step is a professional evaluation. At our Brentwood office, we guide patients through the process of getting a proper diagnosis, whether that involves a home sleep test or a referral for a sleep study.
Why the STOP-BANG Quiz Matters for Your Health
Obstructive sleep apnea is more than just snoring. When left untreated, it can contribute to serious health problems, including heart disease, stroke, type 2 diabetes, and high blood pressure. It also affects mood, memory, and daily performance. Many patients I see in Brentwood and the surrounding San Fernando Valley communities tell me they had no idea their daytime fatigue or morning headaches could be linked to a breathing problem during sleep.
The STOP-BANG screening questionnaire serves as a bridge between “I think something might be wrong” and “Now I know what to do about it.” It empowers you with information. It gives your healthcare provider a starting point for a deeper conversation about your sleep health.
If you have been curious about whether your snoring or daytime tiredness might be a sign of something more, I encourage you to read our blog on the truth about sleep apnea risks, solutions, and what you need to know. It pairs well with understanding your stop bang assessment results.
What Happens After You Take the STOP-BANG Quiz?
Completing the questionnaire is just the beginning. If your STOP-BANG score suggests you may be at risk, here is what typically comes next:
- Professional consultation: A sleep medicine-trained provider reviews your score along with your health history.
- Sleep testing: Depending on your situation, you may undergo a home sleep apnea test or an in-lab polysomnography to confirm the diagnosis.
- Treatment planning: If OSA is confirmed, your provider will discuss treatment options. These can range from CPAP therapy to oral appliance therapy. Many patients prefer a custom oral appliance because it is comfortable, portable, and easy to use.
At the TMJ & Sleep Centre of San Fernando Valley, we specialize in oral appliance therapy for patients who prefer an alternative to CPAP or who have mild-to-moderate OSA. Our team works closely with sleep physicians to make sure every treatment plan is personalized and effective.
Who Should Take the STOP-BANG Questionnaire?
The short answer is: almost anyone can benefit from taking it. However, the quiz is especially valuable for people who experience one or more of the following:
- Loud, chronic snoring
- Witnessed breathing pauses during sleep
- Waking up gasping or choking
- Excessive daytime sleepiness
- Morning headaches
- Difficulty concentrating during the day
It is also a smart idea to take the STOP-BANG quiz if you have a family history of sleep apnea or if you are preparing for surgery. Many hospitals now require a preoperative sleep apnea screening to reduce the risk of complications during anesthesia.

The Role of Dental Professionals in Sleep Apnea Screening
You might wonder why a periodontist would be involved in sleep apnea care. The answer is simple. Dentists see patients more regularly than most other healthcare providers — often twice a year for routine checkups. This frequent contact puts us in a unique position to spot early warning signs like tooth grinding, jaw clenching, and certain oral anatomy features that are linked to airway obstruction.
At our Brentwood practice, we incorporate the STOP-BANG sleep apnea screening into our patient evaluations when risk factors are present. We believe that early detection leads to earlier treatment, and earlier treatment leads to a healthier, more energized life.
Taking the First Step Toward Better Sleep
Knowing your stop bang score is one of the easiest and most meaningful things you can do for your sleep health. The quiz is free, fast, and backed by decades of clinical research. Whether you score low and gain peace of mind, or score higher and decide to seek further evaluation, you are making a proactive choice.
If you live in Brentwood, Encino, Tarzana, or anywhere in the greater Los Angeles area, our team at the TMJ & Sleep Centre of San Fernando Valley is here to help. We are passionate about helping patients breathe better, sleep better, and live better. A quick screening questionnaire could be the turning point you have been looking for.
Frequently Asked Questions
What is a good STOP-BANG score?
A score of 0 to 2 is considered low risk for obstructive sleep apnea. This means you are less likely to have the condition, though it does not completely rule it out. If you still experience symptoms like loud snoring or daytime fatigue, it is worth discussing your results with a healthcare provider.
How accurate is the STOP-BANG questionnaire for detecting sleep apnea?
The STOP-BANG questionnaire is highly accurate, especially for moderate-to-severe obstructive sleep apnea. Studies show a sensitivity of over 95% when the score is 5 or higher. It is one of the most validated screening tools available for sleep-disordered breathing.
Can a dentist use the STOP-BANG quiz to screen for sleep apnea?
Yes, dentists are well-positioned to use the STOP-BANG screening tool because they see patients regularly and can identify oral risk factors for airway obstruction. Many dental offices now incorporate this questionnaire as part of comprehensive patient evaluations. Your dentist can then refer you for further testing if your score indicates risk.
What should I do if my STOP-BANG score is 5 or higher?
A score of 5 or higher places you in the high-risk category for obstructive sleep apnea. You should schedule an appointment with a sleep specialist or a sleep-trained dental provider for further evaluation. A diagnostic sleep study can confirm whether you have OSA and help guide the best treatment plan for you.
Is the STOP-BANG questionnaire the same as a sleep apnea diagnosis?
No, the STOP-BANG questionnaire is a screening tool, not a diagnostic test. It identifies your risk level for obstructive sleep apnea based on common risk factors. A confirmed diagnosis requires a sleep study, such as a home sleep test or an in-lab polysomnography, interpreted by a qualified provider.
