Anti-snoring devices help many people with positional or tongue-based snoring, with custom-fitted mandibular advancement devices (MADs) outperforming over-the-counter mouthguards. They are not a treatment for sleep apnoea — sleep apnoea is a medical diagnosis requiring sleep specialist assessment. At Dental & Wellness London in Islington, custom anti-snoring devices are fitted by Dr Vee Patel after appropriate screening.
The important upfront caveat — snoring vs sleep apnoea
Snoring is soft-tissue vibration during sleep, not by itself a medical condition. Sleep apnoea is a medical condition where the airway repeatedly closes, diagnosed only by sleep medicine specialists via a sleep study — never self-diagnosed. If you have warning signs (daytime sleepiness, witnessed breathing pauses, morning headaches, high blood pressure), seek sleep medicine assessment first. Our guide to snoring and sleep apnoea explains how the two differ.
The categories of anti-snoring device
1. Mandibular advancement devices (MADs) — hold the jaw slightly forward, opening the airway behind the tongue. Custom-fitted versions (quoted in writing after assessment) meaningfully outperform boil-and-bite versions (£20-£100) on fit, comfort, and adjustability, reducing or eliminating snoring in 60-90% of appropriately selected cases.
2. Tongue-stabilising devices — hold the tongue forward by suction; less well-tolerated than MADs, thinner evidence base.
3. Chin straps — work only for mouth-open sleepers with adequate nasal breathing who tolerate the strap; mixed evidence.
4. Nasal devices — strips and dilators help nasal-obstruction snoring specifically, not soft-palate or tongue-driven snoring.
5. Positional therapy — effective for purely positional snorers, the cheapest option where applicable.
Which device suits which patient
Tongue-base obstruction → custom MAD. Nasal obstruction → nasal strips or ENT assessment. Mouth-open sleeping → chin strap. Position-only → positional device. Sleep apnoea suspected → sleep medicine specialist first.
Do over-the-counter devices work?
Sometimes, but fit imprecision, fixed advancement, poor durability, and bite-changing risk over months of nightly use all favour custom-fitted devices for sustained use.
How long until it works?
MADs often show effect from the first night, optimised over 2-4 weeks of incremental adjustment. If a properly-fitted device shows no benefit after 4-6 weeks, it likely isn't the right intervention.
Side effects
MADs: initial jaw soreness, excess saliva, minor temporary bite changes on removal, possible tooth movement over months (monitored with custom devices). Other devices carry their own minor, usually resolving side effects. The bigger risk with any device is masking undiagnosed sleep apnoea.
When to see a sleep medicine specialist first
Witnessed breathing pauses, waking gasping, daytime sleepiness, morning headaches, resistant high blood pressure, unintentional daytime sleep, or BMI above 30 with significant snoring — all warrant medical assessment before self-treating with a device. DWL doesn't diagnose sleep apnoea; it screens and refers where appropriate.
What the DWL service offers
A 45-minute consultation including airway-aware assessment and screening, custom impressions if a MAD is appropriate, fitting 2-3 weeks later, and follow-up over 4-6 weeks to optimise advancement.
Frequently asked questions
Do anti-snoring mouthguards actually work? Custom MADs work for 60-90% of appropriately selected patients without sleep apnoea.
Do they work for sleep apnoea? They reduce snoring sound but aren't a sleep apnoea treatment unless prescribed by a sleep specialist.
MAD vs CPAP — which is better? A clinical decision for sleep specialists; CPAP suits moderate-to-severe cases, MADs suit mild-to-moderate or CPAP-intolerant patients.
How much do devices cost? Boil-and-bite MADs £20-£100; custom-fitted MADs are quoted in writing after assessment.
How long do they last? Custom MADs 2-4 years; boil-and-bite versions 6-12 months.
Should I see a doctor or dentist first? Warning signs mean a doctor first; otherwise dental sleep consultation is a reasonable start, with referral if needed.
