Louder snoring usually has reasons—and many are manageable.
Worsening snoring often reflects multiple factors: nasal blockage increases airflow turbulence; alcohol relaxes throat muscles; weight gain narrows the airway; back-sleeping promotes airway collapse; and jaw/oral anatomy can reduce airway space.
Here are 5 reasons why your snoring might be getting worse, and how professional care can help.
Cause 1: Nasal Congestion & Allergies
Persistent congestion increases resistance and vibration in the airway. For many, treating the underlying allergy or sinus issue is the first step to quieter sleep.
Cause 2: Jaw and Oral Structure—Where Dentists Can Contribute
Jaw position, bite, tongue posture, and oral tissues may affect airway space. Dentists can assess these factors and determine whether oral appliance therapy may be suitable. For example, a receding chin or a large tongue can naturally crowd the airway when you lie down.
Cause 3: Alcohol or Sedatives Before Bed
These substances relax the upper-airway muscles, making them more likely to collapse during sleep. If you notice your snoring is worse after a drink, this is the physiological reason why.
Cause 4: Weight Gain
The NHLBI (NIH) identifies obesity as a major risk factor for sleep apnoea. Weight gain doesn’t just affect your waistline; it can increase neck circumference, putting pressure on the throat and narrowing the airway.
Cause 5: Sleep Position (Especially Sleeping on Your Back)
Back-sleeping allows gravity to pull the tongue and soft tissues backward, worsening airway obstruction. For some, simply switching to side-sleeping can make a significant difference.
Solutions: From Lifestyle Steps to Dentist-Led Options
A) Lifestyle Changes
- Reduce alcohol intake before bed.
- Weight management.
- Treat nasal congestion (consult your GP).
- Try side-sleeping.
B) Dentist-Provided Custom Oral Appliances
The AASM/AADSM guidelines recommend custom, titratable devices provided by qualified dentists when oral appliance therapy is used.
These devices (Mandibular Advancement Devices) gently hold the lower jaw forward to keep the airway open.
Note: Store-bought “boil-and-bite” guards are generally not recommended for treating snoring or sleep apnea as they can be uncomfortable, less effective, and may cause jaw joint issues.
C) If OSA is Suspected
If you experience breathing pauses, choking/gasping, or excessive daytime sleepiness, seek medical evaluation and consider a sleep test.
Common Questions (FAQ)
Q1: Is snoring always Sleep Apnea?
No, but loud snoring accompanied by pauses in breathing or daytime fatigue is a strong indicator of OSA.
Q2: Can I just buy a mouthguard online?
Clinical guidelines advise against this. A custom device, fitted by a dentist, ensures the appliance is effective and does not damage your teeth or jaw joint (TMJ).
Q3: When should I see a doctor?
If your snoring disrupts your partner’s sleep or your own daily energy levels, it is time for a professional assessment.
Book an Assessment
If your snoring is worsening, we recommend consulting a qualified dentist. They can perform a specific airway and bite assessment to discuss if a custom Mandibular Advancement Device is right for you, and coordinate with medical specialists for a sleep test if necessary.
Remember, each treatment method has its pros and cons. It is important to have a basic understanding of the different procedures and associated risks.
