Will it work if I have severe sleep apnea?

It can, though CPAP controls severe apnea more completely and is the first recommendation. For someone with severe apnea who genuinely cannot tolerate CPAP, an appliance is an accepted option and a well-used appliance is better than an unused mask. Objective retesting matters more in severe cases.

Can I use it if I have dentures or missing teeth?

It depends on what remains. The appliance anchors on the teeth, so sufficient sound teeth in both arches are needed. Full dentures generally rule it out; partial tooth loss often does not. Implants can change the picture. This is assessed directly rather than assumed.

How long does one last?

Several years with reasonable care, though grinders wear through devices faster. Regular review checks the fit, the bite and the joint — an appliance that no longer fits properly stops treating the airway effectively and starts loading the teeth unevenly.

Oral Appliance Therapy in New York

An oral appliance is a custom device worn during sleep that holds the lower jaw slightly forward, which carries the tongue and soft tissue with it and enlarges the airway behind them. It is the main dental treatment for obstructive sleep apnea, and for many people the difference between treatment they tolerate and treatment they abandon.

How it works

The device consists of upper and lower components connected so that the mandible is held in a protruded position through the night. Advancing the mandible pulls the tongue base forward and increases tension in the pharyngeal walls, enlarging the airway and making collapse less likely. It is a mechanical solution to a mechanical problem, and it works only while it is being worn — there is no residual effect on nights it is left out.

Custom, and why the distinction is not marketing

A custom appliance is made from impressions or a digital scan of your own teeth and, critically, is adjustable so the degree of advancement can be titrated over weeks to find the point where breathing improves without straining the joint. Boil-and-bite devices sold online are bulky, fit poorly, cannot be titrated, and distribute force unevenly across the teeth. Trials comparing the two consistently favour custom titratable devices, and the poorly-fitting alternatives are a common source of tooth movement and jaw discomfort.

Titration is the part people underestimate

The appliance is not set at its final position on day one. It starts at a modest advancement and is progressively adjusted over several weeks, balancing symptom improvement against jaw comfort. This is why treatment is a course rather than an appointment, and why objective confirmation — a repeat sleep test with the appliance in place — matters. Resolved snoring is encouraging but is not proof that apnoeas have been controlled.

The honest trade-offs

Early on, expect excess salivation or dry mouth, jaw stiffness in the morning, and tooth tenderness; these usually settle within a few weeks. The consequence to take seriously is long-term bite change — small movements of the teeth and a gradual change in how they meet can occur over years of nightly wear. It is usually minor and manageable when monitored, which is exactly why long-term follow-up with someone who understands both the bite and the joint is part of the treatment rather than an optional extra.
