A Dental Appliance for Diagnosed Sleep Apnoea
An oral appliance for sleep apnoea needs a diagnosis, a suitable fit and follow-up testing. Learn how it differs from a guard made for grinding.
A sleep clinician has diagnosed obstructive sleep apnoea and suggested discussing an oral appliance. This is a treatment intended to help keep the airway open during sleep. It is a different job from protecting teeth against grinding, even if both devices are worn in the mouth at night.[2]
Understand which treatment is being proposed
One type holds the lower jaw forward to reduce airway obstruction. The NHLBI describes oral devices as an option when a person cannot tolerate or does not want CPAP. Suitability still needs assessment. Do not replace prescribed treatment with a shop-bought mouthpiece because its packaging mentions snoring.[2]
Bring the sleep report and the name of the clinician managing your sleep care. Ask whether the dentist has received the diagnosis and treatment recommendation. If you already wear a retainer or nightguard, bring it too and ask how the plans fit together. Two different devices should not become two unrelated sets of instructions.
Fitting is the start of follow-up
The joint AASM/AADSM guideline favours a custom, adjustable appliance over a non-custom device when oral-appliance therapy is prescribed for an adult with obstructive sleep apnoea. It also recommends dental oversight for problems such as changes in the bite, with continuing visits involving both dental and sleep clinicians.[1]
Ask who adjusts the appliance, what discomfort to report and what to do if it no longer fits. Get the cleaning and storage instructions for that particular device. A case that closes properly matters more than collecting generic advice for every appliance sold online.
Quieter sleep is not the only check
The guideline recommends follow-up sleep testing to check treatment effectiveness. Feeling better or hearing less snoring is useful information, but it does not replace that assessment. Before leaving, establish who arranges the test and the next dental review. The treatment plan should explain how you will know whether it is working.[1]
